The functioning basic principle of the a few-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Via the motion of a pair of
synchronous gears, the two rotors rotate in reverse directions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the gasoline in the chamber is pushed to achieve the
objective of blowing.

The Application of the Roots Blower

Routine maintenance and inspection
(one) Verify all fasteners and finding pins situations regardless of whether they are loosening.
(2) Constantly check whether or not the leakage phenomenon of the entire body.
(3) Spend focus to lubrication, amount of grease and noises when working,
determine whether or not it operates under the required circumstances.
(four) CZPT & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop position ≥
190ºC). Substitute the lubricant and grease after initial 200 hours working, and exchange
once again after a moth running. Later, exchange the lubricant and grease in accordance to the
surroundings and lubricant (grease) top quality propose a suitable replacement for 3
months.
(five) Constantly check out the inlet air filter, thoroughly clean or exchange the filter in time.
(6) Blower overload often not instantly exhibited, so shell out attention to
the intake and exhaust pressure, bearing temperature and the existing increase traits
of motor to decide no matter whether the blower operates usually
(7) Before disassembling the blower, the assembling relation and proportions
need to be recorded or measured, make marks on elements to make sure the CZPT
specifications following assembling.
(eight) When recently device or overhaul, the oil tank need to be cleaned just before use
and suggest change all grease after eight several hours operating.

Typical failure reason and troubleshooting

No Failure Attainable factors Elimination approaches
one Friction
among the
impeller
(one) Impurities on the impeller,
resulting in the hole is too tiny
(two) Gear dress in, resulting in a
massive backlash
(three) The gear is not effectively mounted,
can not maintain the impeller
synchronization
(four) Bearing wear ensuing in
clearance escalating.
(1) Remove dust and examine
regardless of whether there is hurt parts
(two) Adjust the gear gap, change
the gears if the equipment backlash is
better than the typical 30% to
fifty%
(three)Re-assemble the gears, preserve
the taper make contact with area is to 75%
(4)Change the bearing
two Collision
among
impeller and
wall, the
impeller leading
and casing
(one) Installation gap is not appropriate
(two) running pressure is too
higher, exceeding the specified
value
(3) Working temperature is as well large
(4) Casing or foundation deformation,
positioning supporter failure
(five) Bearing axial location is not excellent
(one) Modify the gap
(2) Recognize triggers of
overloading, decreased the pressure
to the specified worth
(three) Examine the set up
precision and decrease the pipe
tension
(4) Verify and mend bearings,
and to make sure the clearance
(5)Relocation
3 Temperature
also higher
(one) Oil in tank is too significantly, way too
thick or also dirty
(2) CZPT or silencer is blocked
(three)The stress is larger than
the specified benefit
(four)Extreme wear of the
impeller, large hole
(5)Inadequate ventilation, indoor
temperature is substantial, ensuing in
inlet air’s high temperature
(six) The rotating pace is as well low,outcome in the belt slipping.
(one)Lessen the oil level or depend on
oil
(2)Remove of blocking objects
(3)Minimizing the force by way of
the blower
(four)Restore its clearance
(five)Open up vents to decrease space
temperature
(6) Enhance velocity to avoid the
belt slipping.
4 Insufficient
flow
(one) The inlet filter is blocked
(two) Impeller wear and the gap
raises as well much
(three) Belt slipping
(four) Massive imports stress reduction
(5) CZPT ventilation leakage
(one) Cleanse the filter dust and
obstruction
(2) Repair the gap
(3)Tighten the belt and enhance
the number of belts
(four)Alter the inlet stress to the
specified price
(five) Examine and fix the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)Higher tank placement lead to
leakage from the discharge port
(2) Seal use, resulting in shaft oil spills
(three) The pressure is greater than
the specified price

 
(one)Lessen the oil stage
(two)Substitute the seals
(three)Distinct the air vents, 2mm diameter faucet is set in the
center chamber, open up the faucet
below the wall
six Irregular
vibration and
sounds
(1)Bearing clearance exceeds the
specified price or bearing put on
(two) The gear backlash is also
big, not in a tight set
(three) The overseas objects and dust
brought on by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation caused the collision
brought on by overload,
(5) Friction between the impeller
and the inlet housing induced by
overheating
(6) Unbalance of the impeller
triggered by fouling or international
physique
(7) CZPT bolts or other
fasteners are loosened
(one)Exchange bearings or bearing
seat
(2)Reassemble equipment and make certain
backlash
(three)Cleansing blower, check the
case is broken
(four)Examine the back again pressure, examine
the wheel and change gap
(5)Check out the filter and back
strain, increase the hole
amongst the impeller inlet and the
casing
(six)Clear the impeller and the
casing, to guarantee that the impeller
clearance operate
(seven) Tighten the anchor bolts and
leveling the base.
seven Motor
overload
(1)When compared with the necessary
force, the stress big difference
is huge that the again pressure or
the inlet force is large
(2) Compared with the
tools needs, blower
movement is way too large, so its force
boosts
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (caught)
rotating components
(5) The oil amount is too substantial
(6) Slender V-belt is overheat,
vibration is as well big, or pulley
is as well modest
(1) Minimize the stress to the
specified benefit
(2) Exhaust the excess gasoline into
the atmosphere or reduce the
blower speed
(three) Eliminate the obstructions
(4)Quickly shut down, examine
the cause
(5) Alter the oil to the appropriate
level
(6) Check out the belt rigidity, and
replaced it with massive diameter
pulley.
