The working theory of the a few-blade roots blower: two three-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. Through the action 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 fuel in the chamber is pushed to obtain the
goal of blowing.

Feature of our roots blower:
one. Big adjustment of the air volume
two. Reduced Sound
three. Substantial performance
4. Minimal power cosumption
five. Long time lifestyle
6. Reliable operating, straightforward upkeep,small footprint

The Software of the Roots Blower

Upkeep and inspection
(one) Check all fasteners and finding pins problems whether they are loosening.
(two) Often verify whether or not the leakage phenomenon of the physique.
(3) Pay out attention to lubrication, quantity of grease and noises when running,
determine whether it works under the essential problems.
(4) CZPT & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall level ≥
190ºC). Change the lubricant and grease right after first two hundred hours working, and change
yet again soon after a moth operating. Later on, exchange the lubricant and grease in accordance to the
setting and lubricant (grease) high quality suggest a suited alternative for 3
(5) Constantly examine the inlet air filter, clean or substitute the filter in time.
(6) Blower overload sometimes not instantly displayed, so shell out focus to
the intake and exhaust force, bearing temperature and the recent enhance developments
of motor to decide whether or not the blower works normally
(7) Ahead of disassembling the blower, the assembling relation and dimensions
should be recorded or measured, make marks on factors to make sure the CZPT
needs right after assembling.
(eight) When recently equipment or overhaul, the oil tank must be cleaned ahead of use
and propose exchange all grease right after eight several hours working.

Frequent failure reason and troubleshooting

No Failure Achievable causes Elimination strategies
1 Friction
in between the
(1) Impurities on the impeller,
ensuing in the hole is as well tiny
(two) Gear wear, resulting in a
large backlash
(three) The gear is not effectively mounted,
can not maintain the impeller
(four) Bearing wear ensuing in
clearance increasing.
(one) Take away dirt and check
whether or not there is hurt areas
(two) Adjust the gear gap, exchange
the gears if the equipment backlash is
higher than the regular 30% to
(3)Re-assemble the gears, keep
the taper make contact with location is to 75%
(four)Exchange the bearing
2 Collision
in between
impeller and
wall, the
impeller top
and casing
(one) Installation gap is not right
(two) working force is way too
higher, exceeding the specified
(3) Operating temperature is also substantial
(four) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial location is not very good
(1) Modify the hole
(2) Discover triggers of
overloading, diminished the force
to the specified price
(three) Examine the set up
accuracy and reduce the pipe
(4) Check and mend bearings,
and to make sure the clearance
three Temperature
too higher
(one) Oil in tank is way too significantly, also
thick or also dirty
(two) CZPT or silencer is blocked
(3)The force is larger than
the specified price
(four)Abnormal use of the
impeller, huge gap
(five)Very poor air flow, indoor
temperature is high, ensuing in
inlet air’s high temperature
(six) The rotating velocity is also lower,result in the belt slipping.
(one)Decrease the oil stage or count on
(two)Remove of blocking objects
(3)Minimizing the pressure by way of
the blower
(four)Restore its clearance
(5)Open up vents to reduce space
(6) Increase velocity to avoid the
belt slipping.
four Insufficient
(1) The inlet filter is blocked
(two) Impeller dress in and the hole
boosts way too a lot
(3) Belt slipping
(4) Massive imports pressure reduction
(five) CZPT ventilation leakage
(one) Thoroughly clean the filter dust and
(2) Mend the hole
(three)Tighten the belt and increase
the quantity of belts
(four)Modify the inlet pressure to the
specified worth
(five) Check out and fix the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)Substantial tank place cause
leakage from the discharge port
(2) Seal put on, resulting in shaft oil spills
(three) The strain is higher than
the specified benefit

(1)Minimize the oil stage
(2)Change the seals
(3)Very clear the air vents, 2mm diameter faucet is fastened in the
middle chamber, open the faucet
underneath the wall
six Irregular
vibration and
(1)Bearing clearance exceeds the
specified worth or bearing use
(two) The equipment backlash is too
big, not in a restricted set
(three) The foreign objects and dust
caused by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation triggered the collision
caused by overload,
(five) Friction between the impeller
and the inlet housing induced by

(2)Reassemble gear and make sure
(3)Cleansing blower, check out the
situation is destroyed
(four)Check the again force, verify
the wheel and modify gap
(5)Examine the filter and back again
strain, increase the gap
between the impeller inlet and the
(six)Cleanse the impeller and the
casing, to guarantee that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the foundation.
seven Motor
(one)In contrast with the essential
force, the strain big difference
is huge that the again stress or
the inlet strain is substantial
(2) In comparison with the
tools needs, blower
flow is as well huge, so its force
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (stuck)
rotating parts
(5) The oil level is as well higher
(6) Slender V-belt is overheat,
vibration is as well big, or pulley
is as well little
(1) Minimize the force to the
specified worth
(two) Exhaust the surplus fuel into
the environment or decrease the
blower pace
(3) Get rid of the obstructions
(4)Right away shut down, check out
the reason
(five) Change the oil to the proper
(6) Check out the belt rigidity, and
replaced it with huge diameter
