The doing work 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 both sides of the cavity. By means of 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 gas in the chamber is pushed to achieve the
function of blowing.

Feature of our roots blower:
1. Large adjustment of the air volume
two. Reduced Noise
three. Substantial performance
4. Minimal energy cosumption
five. Prolonged time daily life
six. Trustworthy running, easy upkeep,modest footprint

The Application of the Roots Blower

Routine maintenance and inspection
(1) Examine all fasteners and locating pins situations regardless of whether they are loosening.
(two) Often check out regardless of whether the leakage phenomenon of the physique.
(three) Spend consideration to lubrication, amount of grease and noises when operating,
determine whether it functions under the needed circumstances.
(4) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop point ≥
190ºC). Exchange the lubricant and grease right after very first two hundred hours managing, and substitute
once more after a moth operating. Later on, replace the lubricant and grease according to the
environment and lubricant (grease) top quality suggest a appropriate EPT for a few
(five) Constantly check out the inlet air filter, cleanse or change the filter in time.
(six) Blower overload often not instantly displayed, so pay interest to
the intake and exhaust strain, bearing temperature and the current boost traits
of motor to figure out regardless of whether the blower performs usually
(7) Before disassembling the blower, the assembling relation and dimensions
must be recorded or measured, make marks on components to ensure the first
needs soon after assembling.
(8) When freshly device or overhaul, the oil tank need to be cleaned prior to use
and propose change all grease following eight several hours managing.

Widespread failure reason and troubleshooting

No Failure Attainable causes Elimination techniques
one Friction
between the
(1) Impurities on the impeller,
ensuing in the gap is too small
(two) Equipment use, resulting in a
massive backlash
(3) The equipment is not well fixed,
can not keep the impeller
(4) Bearing use ensuing in
clearance escalating.
(1) Remove grime and check
no matter whether there is injury components
(two) Change the equipment hole, replace
the gears if the equipment backlash is
greater than the typical 30% to
(3)Re-assemble the gears, hold
the taper make contact with region is to seventy five%
(4)Change the bearing
2 Collision
impeller and
wall, the
impeller prime
and casing
(1) Set up gap is not correct
(two) working force is also
substantial, exceeding the specified
(3) Running temperature is also higher
(4) Casing or base deformation,
positioning admirer failure
(five) Bearing axial location is not good
(one) Adjust the hole
(two) Discover triggers of
overloading, reduced the force
to the specified value
(3) Check out the installation
accuracy and lessen the pipe
(four) Check out and mend bearings,
and to guarantee the clearance
3 Temperature
also high
(1) Oil in tank is too much, as well
thick or way too soiled
(2) Filter or silencer is blocked
(3)The stress is greater than
the specified worth
(four)Extreme dress in of the
impeller, massive gap
(five)Very poor air flow, indoor
temperature is high, ensuing in
inlet air’s large temperature
(six) The rotating velocity is as well low,consequence in the belt slipping.
(1)Decrease the oil degree or depend on
(2)Get rid of of blocking objects
(three)Minimizing the pressure via
the blower
(four)Fix its clearance
(five)Open vents to minimize place
(six) Boost pace to avert the
belt slipping.
4 Inadequate
(1) The inlet filter is blocked
(two) Impeller dress in and the gap
increases too much
(3) Belt slipping
(4) Massive imports force decline
(5) Pipeline air flow leakage
(one) Thoroughly clean the filter dust and
(2) Repair the hole
(three)Tighten the belt and increase
the number of belts
(four)Adjust the inlet stress to the
specified worth
(five) Check out and fix the pipeline
five Oil leaking or
oil leaking
into the enclosure
(1)Large tank position trigger
leakage from the discharge port
(two) Seal put on, ensuing in shaft oil spills
(three) The force is higher than
the specified benefit

(1)Lessen the oil degree
(two)Change the seals
(3)Clear the air vents, 2mm diameter faucet is fastened in the
middle chamber, open the faucet
below the wall
six Irregular
vibration and
(1)Bearing clearance exceeds the
specified price or bearing wear
(2) The equipment backlash is way too

(6)Thoroughly clean the impeller and the
casing, to make sure that the impeller
clearance perform
(7) Tighten the anchor bolts and
leveling the base.
seven Motor
(one)When compared with the necessary
pressure, the stress difference
is big that the back strain or
the inlet pressure is large
(two) In contrast with the
equipment needs, blower
circulation is too large, so its stress
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (caught)
rotating elements
(five) The oil amount is also higher
(six) Slim V-belt is overheat,
vibration is way too huge, or pulley
is way too little
(one) Reduce the stress to the
specified price
(2) Exhaust the excess fuel into
the environment or decrease the
blower pace
(3) Remove the obstructions
(four)Immediately shut down, check
the cause
(5) Alter the oil to the correct
(6) Verify the belt rigidity, and
replaced it with huge diameter
