The working principle of the a few-blade roots blower: two a few-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. Via the action of a pair of
synchronous gears, the two rotors rotate in opposite 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 attain the
objective of blowing.

Attribute of our roots blower:
one. Big adjustment of the air quantity
two. Low Sounds
three. Substantial effectiveness
four. Low power cosumption
five. Extended time existence
6. Reputable operating, easy maintenance,small footprint

The Application of the Roots Blower

Upkeep and inspection
(1) Check all fasteners and locating pins problems no matter whether they are loosening.
(2) Often check no matter whether the leakage phenomenon of the entire body.
(three) Pay out consideration to lubrication, volume of grease and noises when operating,
determine whether it functions underneath the needed conditions.
(four) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Exchange the lubricant and grease following initial two hundred hrs running, and substitute
once more following a moth working. Afterwards, change the lubricant and grease according to the
atmosphere and lubricant (grease) top quality propose a suited EPT for three
(five) Often verify the inlet air filter, clear or replace the filter in time.
(six) Blower overload often not quickly exhibited, so spend attention to
the ingestion and exhaust stress, bearing temperature and the existing boost tendencies
of motor to determine no matter whether the blower operates usually
(7) Just before disassembling the blower, the assembling relation and dimensions
should be recorded or measured, make marks on parts to make certain the first
requirements following assembling.
(8) When recently equipment or overhaul, the oil tank ought to be cleaned just before use
and propose substitute all grease after 8 hrs managing.

Widespread failure cause and troubleshooting

No Failure Attainable factors Elimination strategies
1 Friction
among the
(one) Impurities on the impeller,
resulting in the hole is as well modest
(2) Gear dress in, ensuing in a
huge backlash
(three) The equipment is not properly fixed,
can not keep the impeller
(4) Bearing put on resulting in
clearance increasing.
(one) Eliminate filth and check
whether or not there is injury parts
(2) Modify the gear gap, exchange
the gears if the equipment backlash is
better than the regular thirty% to
(three)Re-assemble the gears, preserve
the taper speak to spot is to 75%
(four)Replace the bearing
two Collision
in between
impeller and
wall, the
impeller leading
and casing
(1) Set up gap is not correct
(2) functioning force is also
substantial, exceeding the specified
(three) Operating temperature is also higher
(four) Casing or base deformation,
positioning supporter failure
(5) Bearing axial location is not excellent
(one) Adjust the hole
(2) Identify leads to of
overloading, lowered the force
to the specified benefit
(three) Verify the set up
precision and lessen the pipe
(four) Check and restore bearings,
and to guarantee the clearance
3 Temperature
also large
(one) Oil in tank is as well significantly, way too
thick or as well dirty
(two) Filter or silencer is blocked
(3)The pressure is greater than
the specified price
(four)Excessive dress in of the
impeller, huge hole
(five)Very poor air flow, indoor
temperature is substantial, resulting in
inlet air’s higher temperature
(6) The rotating pace is way too minimal,outcome in the belt slipping.
(one)Lessen the oil stage or depend on
(2)Eliminate of blocking objects
(three)Decreasing the stress through
the blower
(4)Fix its clearance
(5)Open up vents to minimize room
(6) Enhance velocity to stop the
belt slipping.
4 Inadequate
(1) The inlet filter is blocked
(two) Impeller put on and the gap
raises way too much
(three) Belt slipping
(four) Large imports pressure reduction
(five) Pipeline ventilation leakage
(one) Cleanse the filter dust and
(2) Restore the gap
(3)Tighten the belt and improve
the amount of belts
(four)Modify the inlet strain to the
specified worth
(5) Examine and fix the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)High tank placement cause
leakage from the discharge port

center chamber, open the faucet
below the wall
six Abnormal
vibration and
(one)Bearing clearance exceeds the
specified value or bearing wear
(two) The gear backlash is also
big, not in a tight fixed

triggered by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation caused the collision
caused by overload,

situation is damaged
(four)Check the back pressure, verify
the wheel and modify gap
(five)Check the filter and again
strain, improve the hole
in between the impeller inlet and the
(6)Thoroughly clean the impeller and the
casing, to ensure that the impeller
clearance function
(seven) Tighten the anchor bolts and
leveling the foundation.
seven Motor
(one)In contrast with the necessary
force, the strain variation
is huge that the back pressure or
the inlet strain is high
(2) When compared with the
products demands, blower
stream is as well massive, so its pressure
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (caught)
rotating components
(5) The oil stage is way too substantial
(6) Slender V-belt is overheat,
vibration is way too large, or pulley
is way too tiny
(1) Minimize the pressure to the
specified value
(2) Exhaust the surplus fuel into
the ambiance or decrease the
blower pace
(three) Eliminate the obstructions
(four)Quickly shut down, verify
the reason
(5) Adjust the oil to the right
(6) Check the belt rigidity, and
changed it with huge diameter
