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

Function of our roots blower:
1. Big adjustment of the air quantity
2. Reduced Sounds
three. Substantial effectiveness
4. Lower vitality cosumption
five. Extended time daily life
6. Reliable working, straightforward upkeep,small footprint

The Software of the Roots Blower

Upkeep and inspection
(1) Check all fasteners and locating pins situations regardless of whether they are loosening.
(two) Always check out no matter whether the leakage phenomenon of the human body.
(three) Shell out consideration to lubrication, sum of grease and noises when operating,
decide whether or not it operates underneath the essential situations.
(four) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall position ≥
190ºC). Exchange the lubricant and grease following 1st two hundred hrs working, and exchange
once again soon after a moth managing. Later on, replace the lubricant and grease in accordance to the
surroundings and lubricant (grease) high quality suggest a suitable EPT for 3
(five) Often check the inlet air filter, clean or change the filter in time.
(6) Blower overload often not immediately displayed, so pay interest to
the ingestion and exhaust strain, bearing temperature and the existing increase trends
of motor to determine whether or not the blower operates usually
(seven) Prior to disassembling the blower, the assembling relation and proportions
must be recorded or measured, make marks on parts to make certain the original
specifications after assembling.
(eight) When freshly device or overhaul, the oil tank should be cleaned just before use
and propose substitute all grease following eight hours running.

Widespread failure purpose and troubleshooting

No Failure Attainable motives Elimination strategies
one Friction
between the
(1) Impurities on the impeller,
ensuing in the hole is as well little
(2) Equipment dress in, ensuing in a
huge backlash
(three) The gear is not nicely fastened,
can not keep the impeller
(4) Bearing wear resulting in
clearance escalating.
(1) Remove dust and verify
whether or not there is damage components
(two) Alter the gear gap, replace
the gears if the gear backlash is
greater than the typical 30% to
(3)Re-assemble the gears, keep
the taper speak to region is to seventy five%
(4)Substitute the bearing
two Collision
in between
impeller and
wall, the
impeller prime
and casing
(1) Set up hole is not correct
(two) functioning pressure is too
higher, exceeding the specified
(3) Running temperature is too large
(4) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial spot is not very good
(1) Alter the gap
(2) Determine triggers of
overloading, reduced the strain
to the specified price
(three) Examine the installation
accuracy and lessen the pipe
(four) Check out and restore bearings,
and to make certain the clearance
3 Temperature
as well higher
(one) Oil in tank is as well significantly, also
thick or too soiled
(2) Filter or silencer is blocked
(three)The pressure is increased than
the specified worth
(four)Too much wear of the
impeller, big hole
(five)Very poor ventilation, indoor
temperature is substantial, resulting in
inlet air’s higher temperature
(6) The rotating pace is way too minimal,outcome in the belt slipping.
(1)Decrease the oil amount or rely on
(2)Eliminate of blocking objects
(3)Lowering the strain via
the blower
(4)Restore its clearance
(5)Open up vents to decrease area
(six) Increase velocity to stop the
belt slipping.
4 Insufficient
(one) The inlet filter is blocked
(two) Impeller use and the gap
increases too much
(3) Belt slipping
(4) Large imports strain loss
(five) Pipeline ventilation leakage
(one) Thoroughly clean the filter dust and
(two) Restore the gap
(three)Tighten the belt and enhance
the amount of belts
(four)Adjust the inlet strain to the
specified worth
(5) Verify and repair the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)Higher tank situation lead to
leakage from the discharge port
(two) Seal wear, ensuing in shaft oil spills
(3) The pressure is higher than
the specified value

(one)Reduce the oil level
(two)Substitute the seals
(three)Distinct the air vents, 2mm diameter faucet is set in the
middle chamber, open up the faucet
beneath the wall
6 Irregular
vibration and
(one)Bearing clearance exceeds the
specified price or bearing use
(two) The equipment backlash is too
huge, not in a tight mounted
(three) The foreign objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation induced the collision
caused by overload,
(5) Friction among the impeller
and the inlet housing brought on by
(six) Unbalance of the impeller
triggered by fouling or foreign
(seven) Anchor bolts or other
fasteners are loosened
(one)Exchange bearings or bearing
(two)Reassemble equipment and make certain
(3)Cleaning blower, check out the
situation is destroyed
(4)Check out the back again pressure, examine
the wheel and alter gap
(five)Examine the filter and back
stress, enhance the hole
among the impeller inlet and the
(6)Thoroughly clean the impeller and the
casing, to ensure that the impeller
clearance operate
(7) Tighten the anchor bolts and
leveling the base.
7 Motor
(1)When compared with the essential
pressure, the force difference
is huge that the back again strain or
the inlet stress is large
(two) In contrast with the
gear needs, blower
movement is way too large, so its stress
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (caught)
rotating components
(five) The oil level is also higher
(six) Slender V-belt is overheat,
vibration is way too huge, or pulley
is too small
(1) Reduce the stress to the
specified value
(two) Exhaust the excessive fuel into
the ambiance or decrease the
blower velocity
(3) Take away the obstructions
(four)Immediately shut down, check
the purpose
(five) Alter the oil to the right
(six) Check out the belt stress, and
replaced it with massive diameter
