JZB Roots vacuum pump

1. Construction features and working principle of the pump:
Model ZJ Mechanical Booster Pump, also known as a Roots pump, is a volumetric pump.
It employs a pair of rotors, identical and in 8-figure with certain clearance between them
in the pump housing, rotating at the same speed in opposite directions to perform
function of suction and discharge of gas. The 2 rotors are supported by rolling bearings
in the end covers of the pump, rotating at high speed and are kept at a
fixed relative position by a pair of timing gears. The end clearance between rotors and
end covers are fixed by adjustable metal shims between the bearing housings and the
end cover at the fixed end, which ensures one-direction expansion of the rotor when
temperature rises during its operation.
Four sets of inner seals (also known as piston ring) in the 2 end covers prevent lube oil
entering into the pump housing. The shaft seal at the front-end cover, also called as
framework oil seal or shaft seal, prevents leakage of air into the pump housing.
In order to reduce temperature of the pump, all models of pumps (expect the two
smallest models) are equipped with a gearbox cooler and front-end cover cooler.
Power is transmitted through a coupling or V-belt from the motor to the driving shaft of
the pump and then through synchronizing gears to the driven shaft

What Is the Role of Vacuum Pumps in Pharmaceutical Manufacturing?

Vacuum pumps play a crucial role in various aspects of pharmaceutical manufacturing. Here’s a detailed explanation:

Vacuum pumps are extensively used in pharmaceutical manufacturing processes to support a range of critical operations. Some of the key roles of vacuum pumps in pharmaceutical manufacturing include:

1. Drying and Evaporation: Vacuum pumps are employed in drying and evaporation processes within the pharmaceutical industry. They facilitate the removal of moisture or solvents from pharmaceutical products or intermediates. Vacuum drying chambers or evaporators utilize vacuum pumps to create low-pressure conditions, which lower the boiling points of liquids, allowing them to evaporate at lower temperatures. By applying vacuum, moisture or solvents can be efficiently removed from substances such as active pharmaceutical ingredients (APIs), granules, powders, or coatings, ensuring the desired product quality and stability.

2. Filtration and Filtrate Recovery: Vacuum pumps are used in filtration processes for the separation of solid-liquid mixtures. Vacuum filtration systems typically employ a filter medium, such as filter paper or membranes, to retain solids while allowing the liquid portion to pass through. By applying vacuum to the filtration apparatus, the liquid is drawn through the filter medium, leaving behind the solids. Vacuum pumps facilitate efficient filtration, speeding up the process and improving product quality. Additionally, vacuum pumps can aid in filtrate recovery by collecting and transferring the filtrate for further processing or reuse.

3. Distillation and Purification: Vacuum pumps are essential in distillation and purification processes within the pharmaceutical industry. Distillation involves the separation of liquid mixtures based on their different boiling points. By creating a vacuum environment, vacuum pumps lower the boiling points of the components, allowing them to vaporize and separate more easily. This enables efficient separation and purification of pharmaceutical compounds, including the removal of impurities or the isolation of specific components. Vacuum pumps are utilized in various distillation setups, such as rotary evaporators or thin film evaporators, to achieve precise control over the distillation conditions.

4. Freeze Drying (Lyophilization): Vacuum pumps are integral to the freeze drying process, also known as lyophilization. Lyophilization is a dehydration technique that involves the removal of water or solvents from pharmaceutical products while preserving their structure and integrity. Vacuum pumps create a low-pressure environment in freeze drying chambers, allowing the frozen product to undergo sublimation. During sublimation, the frozen water or solvent directly transitions from the solid phase to the vapor phase, bypassing the liquid phase. Vacuum pumps facilitate efficient and controlled sublimation, leading to the production of stable, shelf-stable pharmaceutical products with extended shelf life.

5. Tablet and Capsule Manufacturing: Vacuum pumps are utilized in tablet and capsule manufacturing processes. They are involved in the creation of vacuum within tablet presses or capsule filling machines. By applying vacuum, the air is removed from the die cavity or capsule cavity, allowing for the precise filling of powders or granules. Vacuum pumps contribute to the production of uniform and well-formed tablets or capsules by ensuring accurate dosing and minimizing air entrapment, which can affect the final product quality.

6. Sterilization and Decontamination: Vacuum pumps are employed in sterilization and decontamination processes within the pharmaceutical industry. Autoclaves and sterilizers utilize vacuum pumps to create a vacuum environment before introducing steam or chemical sterilants. By removing air or gases from the chamber, vacuum pumps assist in achieving effective sterilization or decontamination by enhancing the penetration and distribution of sterilants. Vacuum pumps also aid in the removal of sterilants and residues after the sterilization process is complete.

It’s important to note that different types of vacuum pumps, such as rotary vane pumps, dry screw pumps, or liquid ring pumps, may be utilized in pharmaceutical manufacturing depending on the specific requirements of the process and the compatibility with pharmaceutical products.

In summary, vacuum pumps play a vital role in various stages of pharmaceutical manufacturing, including drying and evaporation, filtration and filtrate recovery, distillation and purification, freeze drying (lyophilization), tablet and capsule manufacturing, as well as sterilization and decontamination. By enabling efficient and controlled processes, vacuum pumps contribute to the production of high-quality pharmaceutical products, ensuring the desired characteristics, stability, and safety.

What Is a Vacuum Pump, and How Does It Work?

A vacuum pump is a mechanical device used to create and maintain a vacuum or low-pressure environment within a closed system. Here’s a detailed explanation:

A vacuum pump operates on the principle of removing gas molecules from a sealed chamber, reducing the pressure inside the chamber to create a vacuum. The pump accomplishes this through various mechanisms and techniques, depending on the specific type of vacuum pump. Here are the basic steps involved in the operation of a vacuum pump:

1. Sealed Chamber:

The vacuum pump is connected to a sealed chamber or system from which air or gas molecules need to be evacuated. The chamber can be a container, a pipeline, or any other enclosed space.

2. Inlet and Outlet:

The vacuum pump has an inlet and an outlet. The inlet is connected to the sealed chamber, while the outlet may be vented to the atmosphere or connected to a collection system to capture or release the evacuated gas.

3. Mechanical Action:

The vacuum pump creates a mechanical action that removes gas molecules from the chamber. Different types of vacuum pumps use various mechanisms for this purpose:

– Positive Displacement Pumps: These pumps physically trap gas molecules and remove them from the chamber. Examples include rotary vane pumps, piston pumps, and diaphragm pumps.

– Momentum Transfer Pumps: These pumps use high-speed jets or rotating blades to transfer momentum to gas molecules, pushing them out of the chamber. Examples include turbomolecular pumps and diffusion pumps.

– Entrapment Pumps: These pumps capture gas molecules by adsorbing or condensing them on surfaces or in materials within the pump. Cryogenic pumps and ion pumps are examples of entrainment pumps.

4. Gas Evacuation:

As the vacuum pump operates, it creates a pressure differential between the chamber and the pump. This pressure differential causes gas molecules to move from the chamber to the pump’s inlet.

5. Exhaust or Collection:

Once the gas molecules are removed from the chamber, they are either exhausted into the atmosphere or collected and processed further, depending on the specific application.

6. Pressure Control:

Vacuum pumps often incorporate pressure control mechanisms to maintain the desired level of vacuum within the chamber. These mechanisms can include valves, regulators, or feedback systems that adjust the pump’s operation to achieve the desired pressure range.

7. Monitoring and Safety:

Vacuum pump systems may include sensors, gauges, or indicators to monitor the pressure levels, temperature, or other parameters. Safety features such as pressure relief valves or interlocks may also be included to protect the system and operators from overpressure or other hazardous conditions.

It’s important to note that different types of vacuum pumps have varying levels of vacuum they can achieve and are suitable for different pressure ranges and applications. The choice of vacuum pump depends on factors such as the required vacuum level, gas composition, pumping speed, and the specific application’s requirements.

In summary, a vacuum pump is a device that removes gas molecules from a sealed chamber, creating a vacuum or low-pressure environment. The pump accomplishes this through mechanical actions, such as positive displacement, momentum transfer, or entrapment. By creating a pressure differential, the pump evacuates gas from the chamber, and the gas is either exhausted or collected. Vacuum pumps play a crucial role in various industries, including manufacturing, research, and scientific applications.

Roots vacuum pump (abbreviated as Roots pump) is a rotary variable capacity vacuum pump without internal compression. It utilizes 2 8-shaped rotors to rotate in the pump casing to generate suction and exhaust effects. Its principle is similar to that of a Roots blower. Due to its operation in a low pressure range, the gas molecules have a large free range, and the resistance of gas leakage through small slits is high, so it can achieve a high compression ratio and can be used as a booster vacuum pump; But it cannot directly discharge the gas into the atmosphere alone, and needs to be used in series with the front stage vacuum pump. The extracted gas is carried into the atmosphere through the front stage vacuum pump.

Roots pumps are widely used in vacuum degassing, vacuum melting, vacuum treatment of molten steel in the vacuum metallurgy industry, as well as in devices such as space simulation and low-density wind tunnels to extract corrosive gases. It can also be used in production processes such as distillation, evaporation, and drying in industries such as chemical, food, pharmaceutical, and motor manufacturing.

The ZJ series Roots vacuum pump is a rotary variable capacity vacuum pump that requires a front stage pump to be used. It has a large pumping speed in a wide pressure range in China and is not sensitive to dust and water vapor in the extracted gas. It is widely used in industries such as metallurgy, chemical industry, food, and electronic coating.

What Is a Roots Vacuum Pump, and How Does It Work?

A Roots vacuum pump, also known as a Roots blower or a rotary lobe pump, is a type of positive displacement vacuum pump that is widely used for various industrial applications. Here’s a detailed explanation of what a Roots vacuum pump is and how it works:

A Roots vacuum pump consists of two synchronized rotors, known as lobes or impellers, that rotate in opposite directions within a housing. The lobes have a unique helical shape with multiple lobes, which allows them to trap and move gas efficiently. The rotors are synchronized with the help of timing gears to maintain precise clearances between the lobes and the housing.

The operation of a Roots vacuum pump can be described in the following steps:

1. Inlet Stage: The process begins with the lobes rotating in opposite directions. As the lobes rotate, the volume between them and the housing gradually increases, creating a larger space at the inlet side of the pump. This expansion of the volume causes the gas to enter the pump through the inlet port. The gas is drawn in due to the pressure difference between the inlet and the pump’s internal chamber.

2. Compression Stage: As the gas enters the pump, it gets trapped in the spaces between the lobes and the housing. As the lobes continue to rotate, the trapped gas gets carried along the rotating lobes. The gas is essentially trapped in the pockets formed by the lobes and the housing. The rotating lobes then compress the gas as they move towards the outlet side of the pump.

3. Outlet Stage: As the lobes approach the outlet side of the pump, the volume between them and the housing decreases, resulting in the compression of the trapped gas. This compression raises the pressure of the gas, causing it to be expelled through the outlet port of the pump. The expelled gas is then discharged into the atmosphere or directed to a downstream process or another vacuum pump, depending on the application.

It’s important to note that a Roots vacuum pump operates as a non-contacting pump, meaning that there is no physical contact between the lobes or between the lobes and the housing. This characteristic eliminates the need for lubrication within the pump and reduces the risk of contamination or oil vapor backstreaming into the vacuum system.

Roots vacuum pumps are known for their high pumping speed and ability to handle large volumes of gas. However, they are not capable of achieving high vacuum levels on their own. To achieve higher vacuum levels, a Roots pump is often used in conjunction with other vacuum pumps, such as rotary vane pumps or diffusion pumps, in a hybrid or combination pumping system.

In summary, a Roots vacuum pump operates based on the principle of positive displacement. It utilizes synchronized rotating lobes to trap and compress gas, allowing it to be discharged at a higher pressure. The non-contacting design of the pump eliminates the need for lubrication and reduces the risk of contamination. Roots vacuum pumps are commonly employed in various industrial applications, especially when high pumping speed and large gas handling capacity are required.

Applications:
The main advantage of Roots vacuum pump is that it can operate with high pumping speed under lower suction pressures, however, has to be backed by a backing pump.Under normal working conditions, it is permissible to not add by-pass pipes.Roots vacuum pump should not operate with a higher-pressure difference than allowable,otherwise overheating and overload will cause damage of Roots vacuum pump.
Therefore, proper backing pump and necessary protection devices must be considered.Oil sealed mechanical pump is usually selected as the fore vacuum pump. Other types of backing pumps may be used where their requirement for ultimate vacuum is not too strict. Particularly, when gas pumped containing large amount of vapor, water-ring vacuum pump maybe an ideal option though ultimate vacuum achieved is on the low side.

How Are Roots Vacuum Pumps Utilized in the Automotive Industry?

Roots vacuum pumps play a significant role in various applications within the automotive industry. Here’s a detailed explanation:

1. Brake System Vacuum Pumps:

– Vacuum Boosters: Roots vacuum pumps are commonly used as vacuum boosters in automotive brake systems. They assist in enhancing the braking performance by providing the necessary vacuum for power brake operation. When the driver applies the brake pedal, the vacuum booster uses the suction power generated by the Roots pump to amplify the force applied to the brake master cylinder, resulting in more effective braking.

– Electric Brake Vacuum Pumps: In modern electric or hybrid vehicles, where traditional engine-driven vacuum sources may not be available, electric brake vacuum pumps are utilized. These pumps, often based on the Roots principle, generate vacuum independently to power the brake booster and ensure reliable braking performance.

2. Emissions Control:

– Evaporative Emission Control: Roots vacuum pumps are employed in evaporative emission control systems to prevent the release of harmful vapors from the fuel system into the atmosphere. These pumps create a vacuum within the system, purging and storing fuel vapors in a canister for subsequent combustion or recycling.

– Positive Crankcase Ventilation (PCV): PCV systems, which are designed to reduce emissions and maintain the integrity of the engine, also utilize Roots vacuum pumps. These pumps draw crankcase gases and vapors, including oil mist, from the engine’s crankcase into the intake manifold for combustion, improving overall engine efficiency and reducing pollution.

3. Engine Testing and Development:

– Vacuum Leakage Testing: Roots vacuum pumps are utilized for vacuum leakage testing in engine manufacturing and development. By creating a vacuum in the intake manifold or other engine components, these pumps enable the detection of leaks and ensure the integrity of the engine’s air delivery system.

– Air Flow Calibration: During engine testing and calibration, Roots vacuum pumps are used to simulate various operating conditions by controlling the intake air flow. This allows engineers to fine-tune the engine’s performance, optimize fuel-air mixture ratios, and assess the engine’s efficiency and emissions characteristics.

4. HVAC Systems:

– Climate Control: Roots vacuum pumps are employed in automotive HVAC (Heating, Ventilation, and Air Conditioning) systems to facilitate the flow and distribution of air. These pumps help regulate the operation of HVAC components, such as air blend doors and vacuum actuators, ensuring proper air temperature and direction control inside the vehicle cabin.

5. Fuel System and Turbocharging:

– Fuel Transfer and Evacuation: In automotive fuel systems, Roots vacuum pumps are used for fuel transfer and evacuation. These pumps assist in priming the fuel system, removing air pockets, and ensuring the continuous flow of fuel to the engine, enhancing the overall fuel delivery performance.

– Turbocharger Control: Roots vacuum pumps are sometimes employed in turbocharged engines to control the actuation of variable geometry turbochargers (VGT). These pumps provide the necessary vacuum signals to actuate the VGT mechanism, optimizing turbocharger performance and enhancing engine efficiency.

6. Other Applications:

– Electric Vehicle Battery Systems: In electric vehicles, Roots vacuum pumps are utilized to create a vacuum in battery enclosures, helping to maintain the integrity and safety of the battery system by preventing the ingress of moisture, dust, or contaminants.

– Engine Air Induction: Some automotive engines utilize Roots-type superchargers or twin-screw superchargers, which are essentially positive displacement Roots vacuum pumps operating in reverse. These devices compress and force air into the engine’s intake manifold, resulting in increased engine power and performance.

In summary, Roots vacuum pumps find extensive utilization in the automotive industry. They play a crucial role in brake systems, emissions control, engine testing and development, HVAC systems, fuel systems, turbocharging, electric vehicle battery systems, and engine air induction. By contributing to braking performance, emissions reduction, engine calibration, HVAC functionality, fuel system efficiency, turbocharger control, battery system safety, and engine power enhancement, Roots vacuum pumps contribute significantly to the overall operation and performance of automotive systems and components.

Can Roots Vacuum Pumps Be Used for Vacuum Distillation?

Yes, Roots vacuum pumps can be used for vacuum distillation in certain applications. Here’s a detailed explanation:

Vacuum distillation is a process used to separate and purify components of a liquid mixture by exploiting the difference in boiling points under reduced pressure. By operating at lower pressures, the boiling points of the components are decreased, allowing for more selective evaporation and separation. Vacuum distillation is commonly employed in industries such as petrochemical, pharmaceutical, and chemical manufacturing.

Roots vacuum pumps can play a role in vacuum distillation processes by assisting in the creation and maintenance of the required vacuum conditions. Although Roots vacuum pumps alone may not achieve the high vacuum levels necessary for certain applications, they are often used in combination with other vacuum pumps, such as rotary vane pumps or oil-sealed pumps, to create a hybrid pumping system.

In a typical setup, Roots vacuum pumps are utilized as the primary roughing pump in the distillation system. Their high pumping speed allows for efficient removal of large volumes of gas, reducing the pressure in the system and enabling the effective operation of subsequent stages. The Roots pump works by trapping and compressing the gas, creating a pressure differential that facilitates the evacuation of the system.

While Roots vacuum pumps are effective in generating rough vacuum levels, they may not be capable of achieving the very high vacuum levels often required for precise separation in vacuum distillation. Therefore, they are commonly used in conjunction with other vacuum pumps, such as oil-sealed pumps or molecular pumps, that are better suited for achieving and maintaining high vacuum levels.

It’s important to note that the selection and configuration of the vacuum pumps for vacuum distillation depend on various factors, including the desired vacuum level, the characteristics of the liquid mixture being distilled, and the specific requirements of the distillation process. The vacuum system needs to be carefully designed to ensure optimal performance and efficient separation.

In summary, while Roots vacuum pumps alone may not be sufficient for achieving the high vacuum levels required for vacuum distillation, they are commonly employed as part of a hybrid pumping system in conjunction with other vacuum pumps. Their high pumping speed and capability to handle large gas volumes make them valuable for creating the initial vacuum conditions in the distillation process.

Can Roots Vacuum Pumps Be Used for Vacuum Impregnation in Manufacturing?

Yes, Roots vacuum pumps can be used for vacuum impregnation in manufacturing. Here’s a detailed explanation:

1. Vacuum Impregnation in Manufacturing: Vacuum impregnation is a process used in manufacturing to fill porous materials or components with a liquid or resin. It is commonly employed to enhance the properties of materials by improving their strength, sealing capability, or resistance to chemicals or corrosion. The process involves placing the porous material in a vacuum chamber and removing the air or gas trapped within its pores. Once a vacuum is established, a liquid or resin is introduced, and the vacuum is released, allowing the material to absorb the impregnating substance.

2. Role of Roots Vacuum Pumps: Roots vacuum pumps play a crucial role in the vacuum impregnation process by creating and maintaining the required vacuum conditions. Here’s how they contribute:

– Evacuation: Roots pumps are used to evacuate the impregnation chamber, removing the air and gas from within the pores of the porous material. By creating a vacuum, the trapped gases are extracted, creating a void space for the impregnating substance to penetrate.

– Pressure Control: Roots pumps help control the pressure within the impregnation chamber during different stages of the process. They can rapidly achieve and maintain the desired vacuum level, ensuring proper impregnation of the material and preventing the formation of air bubbles or voids.

– Gas Removal: Roots pumps effectively remove gases released from the impregnating substance during the impregnation process. As the liquid or resin fills the pores of the porous material, gases may be released due to the reaction or outgassing. The vacuum pump evacuates these gases, preventing their accumulation and ensuring complete impregnation.

3. Advantages of Roots Vacuum Pumps for Vacuum Impregnation:

– High Pumping Speed: Roots vacuum pumps have a high pumping speed, enabling rapid evacuation of the impregnation chamber. This reduces the overall impregnation cycle time, increasing manufacturing throughput and efficiency.

– Large Volume Handling: Roots pumps are capable of handling large volumes of gas, allowing them to evacuate chambers of different sizes effectively. This is advantageous when impregnating large or complex-shaped components that require a significant amount of impregnating substance.

– Continuous Operation: Roots pumps can operate continuously, maintaining the vacuum conditions required for impregnation throughout the process. This ensures consistent impregnation results and reduces the risk of incomplete impregnation or material defects.

– Compatibility with Impregnating Substances: Roots vacuum pumps are compatible with a wide range of impregnating substances, including resins, oils, solvents, and other liquids. They can handle different chemical compositions and provide a clean and efficient environment for the impregnation process.

4. Considerations for Vacuum Impregnation:

– Material Compatibility: It is essential to consider the compatibility of the porous material with the impregnating substance and the impregnation process itself. Some materials may require pre-treatment or surface preparation before impregnation. The choice of impregnating substance should also align with the material’s properties and intended application.

– Process Parameters: Vacuum impregnation involves controlling various process parameters, such as vacuum level, impregnation time, pressure release, and curing conditions. These parameters may vary depending on the material, impregnating substance, and desired impregnation results. Proper process optimization and control are crucial for achieving consistent and reliable impregnation outcomes.

– System Design: The design of the vacuum impregnation system should consider factors such as chamber size, gas flow rates, vacuum pump capacity, and pressure control mechanisms. Proper system design ensures efficient operation, reliable vacuum conditions, and effective impregnation of the porous material.

In summary, Roots vacuum pumps are well-suited for vacuum impregnation in manufacturing. Their high pumping speed, large volume handling capability, continuous operation, and compatibility with impregnating substances make them effective in creating and maintaining the required vacuum conditions for successful impregnation. By considering material compatibility, process parameters, and system design, Roots vacuum pumps contribute to the efficient and reliable impregnation of porous materials in various manufacturing applications.

What Are the Differences Between Dry and Wet Roots Vacuum Pumps?

Dry and wet Roots vacuum pumps are two different types of pumps with distinct operating principles and characteristics. Here’s a detailed explanation of their differences:

1. Operating Principle:

– Dry Roots Vacuum Pump: A dry Roots vacuum pump operates without the use of any lubricating fluid or sealing liquid. It consists of two or more intermeshing lobed rotors that rotate in opposite directions, creating a series of expanding and contracting chambers. As the rotors rotate, gas is trapped in the chambers and carried from the inlet to the outlet, resulting in the generation of a vacuum.

– Wet Roots Vacuum Pump: A wet Roots vacuum pump, also known as a liquid ring pump, uses a liquid, typically water or another compatible liquid, as a sealing and working fluid. The liquid forms a rotating ring inside the pump, creating a seal between the lobes of the rotors. As the rotors turn, the liquid ring traps and carries the gas from the inlet to the outlet, creating a vacuum.

2. Lubrication and Sealing:

– Dry Roots Vacuum Pump: Dry Roots pumps do not require lubrication or sealing fluid. The absence of liquids eliminates the need for maintenance associated with fluid handling, such as oil changes or water management. Dry pumps are often preferred in applications where contamination from lubricants or sealing fluids is a concern, such as in semiconductor manufacturing or pharmaceutical industries.

– Wet Roots Vacuum Pump: Wet Roots pumps rely on a liquid seal for operation, requiring a continuous supply of sealing liquid, typically water. The liquid serves as both a sealant and a coolant for the pump. However, it also necessitates careful management of the liquid, including water supply, disposal, and potential contamination risks. Wet pumps are commonly used in applications where the presence of the sealing liquid is not a concern or can be easily managed.

3. Operation Efficiency:

– Dry Roots Vacuum Pump: Dry pumps are known for their high operational efficiency. They can achieve high pumping speeds and create substantial vacuum levels. Dry pumps are particularly suitable for processes that require quick pump-down times or applications where a deep vacuum is necessary.

– Wet Roots Vacuum Pump: Wet pumps typically have lower pumping speeds compared to dry pumps. While they can achieve moderate vacuum levels, they are not as effective in creating deep vacuums. Wet pumps are often used in processes where the pumping speed requirements are not as demanding, or in applications where the presence of the sealing liquid can provide benefits, such as in handling condensable gases or preventing contamination.

4. Application Suitability:

– Dry Roots Vacuum Pump: Dry pumps are commonly used in a wide range of applications, including semiconductor manufacturing, analytical instruments, vacuum packaging, and industrial processes. Their ability to handle different gases and their high operational efficiency make them suitable for various industries and processes.

– Wet Roots Vacuum Pump: Wet pumps find application in processes where the presence of a sealing liquid is advantageous. They are often used in applications involving the handling of water vapor, condensable gases, or corrosive gases. Wet pumps are utilized in industries such as chemical processing, pharmaceuticals, food processing, and environmental applications.

5. Maintenance and Care:

– Dry Roots Vacuum Pump: Dry pumps generally require less maintenance compared to wet pumps. They do not rely on sealing liquid, reducing the need for fluid changes, disposal, or monitoring of liquid levels. Dry pumps may require periodic maintenance, such as cleaning, inspection, and rotor lubrication, but the maintenance requirements are typically less frequent and less involved.

– Wet Roots Vacuum Pump: Wet pumps require regular maintenance due to the presence of the sealing liquid. Maintenance tasks include monitoring and replenishing the liquid, managing the water supply, and ensuring proper disposal of the used liquid. The sealing liquid may also require filtration or treatment to remove contaminants or prevent scaling or corrosion.

In summary, dry and wet Roots vacuum pumps differ in their operating principles, lubrication and sealing methods, operation efficiency, application suitability, and maintenance requirements. Dry pumps operate without lubrication or sealing fluid, offer high efficiency and are suitable for a wide range of applications. Wet pumps rely on a liquid seal, have lower pumping speeds, are used in applications where the liquid presence is advantageous, and require regular maintenance and care.

Are Roots Vacuum Pumps Used in Industrial Applications?

Yes, Roots vacuum pumps are widely used in various industrial applications. Here’s a detailed explanation of their application in industrial settings:

China Professional 5.5 Kw Zjp-600 Roots Vacuum Pump for Medical Industry with Good quality

Product Description

Working principle

Roots vacuum pump, also known as mechanical booster pump, is a rotary positive displacement vacuum pump. The schematic structure of the Roots vacuum pump is shown in Figure on the left. There are 2 figure-8 rotors in the pump chamber, which are installed on a pair of shafts in parallel, and are driven by a pair of synchronous gear. The rotor and the rotor, the rotors and the pump chamber maintain a certain gap and do not contact each other, so the friction loss during operation is very small, the friction power consumption is extremely small, and high-speed operation can be achieved.

Figure below shows the internal structure of the Roots vacuum pump. The 2 rotors of the pump are supported in the rolling bearings on the end covers on both sides of the pump chamber, and rely on a pair of adjustable synchronous gears to keep the 2 rotors rotating at high speed. A certain mutual position, and the end face gap between the rotor and the end cover is guaranteed by the special structure of the fixed end (closer to the motor side), so that the pump can only expand to 1 end of the gearbox due to heat during operation.

The 4 sets of PTFE piston ring seals in the end caps on both sides can prevent the lubricating oil in the oil tanks on both sides from entering the pump chamber, and the balanced mechanical seal at the outlet shaft can prevent the atmosphere from leaking into the pump chamber.
The cooling method of the pump is usually air cooling. If the pump is used for working in the high pressure range, it is recommended to select a pump with a water cooling structure. The power of the motor is transmitted to the driving shaft through the coupling, and then the driven shaft is driven to rotate by the driving shaft through the synchronous gear. ZJ series Roots vacuum pumps are of horizontal structure, and the pump is directly connected with the motor by means of a coupling. But the pump with special requirements can adopt the V-belt drive structure.

ZJP type Roots vacuum pump with bypass valve is a derivative product of ZJ type Roots vacuum pump. The pumping principle is the same as that of ZJ type pump. It also uses a pair of 8-shaped rotors to maintain a certain gap in the pump casing. It rotates to generate suction and exhaust. The difference is that the inlet and exhaust ports of the ZJP type Roots vacuum pump with bypass valve are connected, and a gravity valve is installed vertically on the channel of the 2 (see Figure on the left). When the force on the valve caused by the pressure difference between the intake port and the exhaust port exceeds the weight of the valve itself, it will automatically open. This value of pressure difference which cause the valve to open is the highest differential pressure at which the pump can operate reliably. Therefore, this valve is actually an overload automatic protection valve, and it is also the biggest advantage of ZJP type Roots vacuum pump. Theoretically, the ZJP Roots pump can be started synchronously with the backing pump under atmospheric pressure to pump the system. If the system volume is large, the bypass valve of the ZJP Roots pump is open for a long time, and the pump’s effective pumping speed is small, so it is not economical to start the ZJP type Roots pump at atmospheric pressure for large systems. It is recommended to start the ZJP Roots vacuum pump when the backing pump reaches a certain pressure.

The advantage of the Roots vacuum pump is that it has a higher pumping speed at a lower inlet pressure, but it cannot be used alone. There must be a backing vacuum pump in series, and the pressure in the system is pumped by the backing vacuum pump to an allowable starting pressure of the Roots vacuum pump before it is started(See figure on the left). In general, the Roots vacuum pump is not allowed to work under high pressure difference, otherwise it will be overloaded, overheated and damaged, so the backing vacuum pump must be selected reasonably, and the necessary protective equipment must be installed.
The backing vacuum pump is generally an oil-sealed mechanical pump, but if the ultimate pressure requirement is not high, other forms of rough vacuum pump can be used as the backing pump, especially when the gas containing a large amount of water vapor is extracted, the dry screw vacuum pump is recommended as the backing pump.

Remark:
1. The pumping speed refers to the maximum pumping speed measured when the inlet pressure of the Roots vacuum pump is in the range of 67 Pa ~ 2.67 Pa under the condition that the recommended backing pump is used.
2. The ultimate pressure refers to the stable minimum air pressure measured at the inlet of the pump with a vacuum gauge after fully operation without any additional container, the pump port is closed and no intake air is provided under the condition that the recommended backing pump is used.
3. The performances in the above table are obtained under the condition that the recommended backing pump is used. Users can choose different backing vacuum pumps according to different situations, but their main performance data will vary.
