The doing work theory of the 3-blade roots blower: two 3-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 way of 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 gas in the chamber is pushed to accomplish the
purpose of blowing.

Function of our roots blower:
1. Huge adjustment of the air quantity
two. Reduced Sounds
three. Substantial effectiveness
four. Reduced power cosumption
five. Prolonged time life
6. Reliable managing, easy upkeep,little footprint

The Application of the Roots Blower

Servicing and inspection
(1) Check all fasteners and locating pins conditions whether or not they are loosening.
(2) Often examine whether the leakage phenomenon of the human body.
(3) Pay focus to lubrication, sum of grease and noises when working,
decide no matter whether it performs beneath the required conditions.
(four) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop point ≥
190ºC). Substitute the lubricant and grease right after 1st two hundred hrs operating, and exchange
once again right after a moth running. Afterwards, substitute the lubricant and grease in accordance to the
environment and lubricant (grease) good quality suggest a appropriate EPT for 3
(five) Constantly check out the inlet air filter, clean or replace the filter in time.
(6) Blower overload occasionally not right away shown, so pay out attention to
the consumption and exhaust force, bearing temperature and the existing enhance tendencies
of motor to figure out whether the blower performs generally
(seven) Just before disassembling the blower, the assembling relation and proportions
must be recorded or calculated, make marks on factors to make certain the unique
needs following assembling.
(8) When newly device or overhaul, the oil tank need to be cleaned just before use
and suggest substitute all grease right after eight hours operating.

Widespread failure explanation and troubleshooting

No Failure Achievable causes Elimination methods
1 Friction
among the
(one) Impurities on the impeller,
resulting in the gap is as well little
(two) Equipment dress in, ensuing in a
large backlash
(three) The gear is not effectively fixed,
can not keep the impeller
(four) Bearing use ensuing in
clearance rising.
(1) Remove dust and examine
whether there is injury areas
(2) Adjust the gear hole, replace
the gears if the equipment backlash is
better than the regular thirty% to
(three)Re-assemble the gears, hold
the taper get in touch with region is to seventy five%
(four)Replace the bearing
2 Collision
impeller and
wall, the
impeller best
and casing
(one) Set up hole is not correct
(2) running strain is way too
high, exceeding the specified
(3) Running temperature is way too substantial
(four) Casing or base deformation,
positioning supporter failure
(5) Bearing axial area is not very good
(one) Modify the gap
(2) Discover leads to of
overloading, diminished the strain
to the specified price
(three) Verify the set up
precision and lessen the pipe
(four) Check and restore bearings,
and to make certain the clearance
3 Temperature
also large
(one) Oil in tank is also a lot, way too
thick or also filthy
(2) Filter or silencer is blocked
(three)The stress is higher than
the specified value
(4)Too much use of the
impeller, huge gap
(five)Very poor ventilation, indoor
temperature is large, ensuing in
inlet air’s high temperature
(6) The rotating pace is too minimal,end result in the belt slipping.
(one)Lessen the oil stage or count on
(two)Eliminate of blocking objects
(three)Decreasing the strain by means of
the blower
(four)Fix its clearance
(5)Open vents to minimize place
(6) Enhance pace to avert the
belt slipping.
four Insufficient
(1) The inlet filter is blocked
(2) Impeller wear and the gap
will increase as well a lot
(3) Belt slipping
(4) Massive imports pressure reduction
(five) Pipeline air flow leakage
(one) Clean the filter dust and
(two) Restore the gap
(3)Tighten the belt and enhance
the variety of belts
(4)Adjust the inlet pressure to the
specified price
(5) Check and fix the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(one)Substantial tank place cause
leakage from the discharge port
(two) Seal dress in, ensuing in shaft oil spills
(3) The stress is greater than
the specified value

(one)Decrease the oil amount
(2)Exchange the seals
(3)Very clear the air vents, 2mm diameter faucet is mounted in the
middle chamber, open up the faucet
under the wall
six Abnormal
vibration and
(one)Bearing clearance exceeds the
specified benefit or bearing dress in
(2) The gear backlash is way too
massive, not in a tight fastened
(three) The international objects and dust
caused by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation caused 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 international
(seven) Anchor bolts or other
fasteners are loosened
(1)Substitute bearings or bearing
(two)Reassemble equipment and make certain
(3)Cleaning blower, check out the
scenario is ruined
(4)Verify the again force, check
the wheel and modify hole
(five)Verify the filter and back again
force, boost the gap
in between the impeller inlet and the
(six)Thoroughly clean the impeller and the
casing, to make certain that the impeller
clearance operate
(7) Tighten the anchor bolts and
leveling the base.
7 Motor
(1)In contrast with the necessary
stress, the strain variation
is big that the back again force or
the inlet strain is high
(2) When compared with the
products demands, blower
flow is also big, so its stress
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (caught)
rotating parts
(five) The oil degree is also substantial
(6) Slim V-belt is overheat,
vibration is also large, or pulley
is way too modest
(one) Reduce the pressure to the
specified value
(2) Exhaust the excess gas into
the atmosphere or lessen the
blower velocity
(3) Get rid of the obstructions
(4)Right away shut down, check
the explanation
(five) Change the oil to the right
(six) Check out the belt stress, and
replaced it with huge diameter
