The working basic principle of the a few-blade roots blower: two three-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. By means of the action of a pair of
synchronous gears, the two rotors rotate in reverse instructions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the gas in the chamber is pushed to achieve the
purpose of blowing.
Function of our roots blower:

Our Roots Blower Workshop
Doosn Horzitonal CZPT Middle
The Application of the Roots Blower
Upkeep and inspection
(one) Check out all fasteners and finding pins conditions no matter whether they are loosening.
(2) Often check out whether the leakage phenomenon of the entire body.
(three) Pay attention to lubrication, quantity of grease and noises when operating,
establish whether or not it operates under the necessary conditions.
(four) CZPT & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall stage ≥
190ºC). Replace the lubricant and grease right after initial two hundred hrs working, and change
once again following a moth running. Later, replace the lubricant and grease in accordance to the
environment and lubricant (grease) good quality propose a appropriate replacement for a few
months.
(five) Usually check the inlet air filter, clear or change the filter in time.
(6) Blower overload at times not immediately shown, so pay attention to
the consumption and exhaust stress, bearing temperature and the present enhance traits
of motor to determine whether the blower performs usually
(seven) Before disassembling the blower, the assembling relation and dimensions
should be recorded or measured, make marks on components to guarantee the CZPT
needs after assembling.
(8) When recently equipment or overhaul, the oil tank must be cleaned ahead of use
and suggest exchange all grease soon after eight hrs running.
Widespread failure purpose and troubleshooting
No | Failure | Achievable reasons | Elimination approaches |
1 | Friction amongst the impeller |
(one) Impurities on the impeller, resulting in the hole is also modest (two) Equipment put on, ensuing in a huge backlash (three) The equipment is not properly mounted, can not sustain the impeller synchronization (4) Bearing put on ensuing in clearance rising. |
(1) Get rid of grime and verify regardless of whether there is damage areas (2) Alter the equipment gap, exchange the gears if the equipment backlash is increased than the typical 30% to fifty% (3)Re-assemble the gears, hold the taper get in touch with region is to 75% (4)Replace the bearing |
2 | Collision among impeller and wall, the impeller leading and casing |
(one) Set up hole is not proper (two) working force is too high, exceeding the specified value (three) Working temperature is too substantial (4) Casing or base deformation, positioning admirer failure (5) Bearing axial place is not excellent |
(1) Adjust the gap (two) Determine leads to of overloading, reduced the stress to the specified worth (three) Examine the installation precision and decrease the pipe stress (four) Verify and fix bearings, and to guarantee the clearance (five)Relocation |
3 | Temperature also substantial |
(1) Oil in tank is as well much, as well thick or as well soiled (two) CZPT or silencer is blocked (three)The force is increased than the specified price (4)Excessive wear of the impeller, large hole (5)Poor air flow, indoor temperature is large, resulting in inlet air’s large temperature (six) The rotating velocity is way too lower,end result in the belt slipping. |
(one)Decrease the oil stage or rely on oil (2)Eliminate of blocking objects (three)Minimizing the force via the blower (four)Fix its clearance (five)Open vents to reduce place temperature (six) Improve velocity to stop the belt slipping. |
4 | Inadequate stream |
(one) The inlet filter is blocked (2) Impeller wear and the hole will increase too considerably (three) Belt slipping (four) Large imports pressure reduction (5) CZPT air flow leakage |
(one) Thoroughly clean the filter dust and obstruction (2) Mend the hole (3)Tighten the belt and improve the variety of belts (4)Adjust the inlet force to the specified benefit (5) Check and fix the pipeline |
five | Oil leaking or oil leaking into the enclosure |
(1)Substantial tank situation lead to leakage from the discharge port (2) Seal use, resulting in shaft oil spills (3) The strain is larger than the specified benefit |
(one)Reduce the oil degree (two)Replace the seals (three)Distinct the air vents, 2mm diameter faucet is mounted in the middle chamber, open up the faucet underneath the wall |
6 | Irregular vibration and sound |
(1)Bearing clearance exceeds the specified benefit or bearing dress in (two) The gear backlash is too large, not in a limited set (3) The foreign objects and dust triggered by the impeller and the impeller, the impeller and the housing collision (four) the impeller shaft deformation induced the collision brought on by overload, (five) Friction between the impeller and the inlet housing caused by overheating (6) Unbalance of the impeller induced by fouling or international body (seven) CZPT bolts or other fasteners are loosened |
(1)Replace bearings or bearing seat (2)Reassemble gear and make sure backlash (three)Cleansing blower, verify the circumstance is ruined (four)Check the again stress, examine the wheel and modify gap (five)Examine the filter and back stress, increase the hole between the impeller inlet and the casing (6)Clear the impeller and the casing, to ensure that the impeller clearance perform (seven) Tighten the anchor bolts and leveling the foundation. |
7 | Motor overload |
(one)When compared with the needed pressure, the pressure big difference is huge that the back again stress or the inlet strain is high (two) In contrast with the products specifications, blower flow is also large, so its pressure raises (3)Inlet filter is blocked, or outlet pipe is obstructed or blocked (four) Collusion or friction (trapped) rotating parts (5) The oil level is also large (6) Slim V-belt is overheat, vibration is too large, or pulley is as well modest |
(1) Minimize the stress to the specified worth (two) Exhaust the excessive fuel into the ambiance or reduce the blower velocity (three) Take away the obstructions (four)Right away shut down, verify the explanation (5) Modify the oil to the proper degree (six) Verify the belt stress, and replaced it with massive diameter pulley. |
