The working principle 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. Through 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
goal of blowing.

Function of our roots blower:
one. Huge adjustment of the air volume
2. Low Noise
three. Large performance
four. Low vitality cosumption
5. Lengthy time lifestyle
6. Trustworthy working, easy servicing,tiny footprint

The Application of the Roots Blower

Maintenance and inspection
(one) Check all fasteners and finding pins situations whether they are loosening.
(2) Always examine regardless of whether the leakage phenomenon of the entire body.
(3) Spend attention to lubrication, volume of grease and noises when managing,
decide whether or not it works beneath the required situations.
(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, fall position ≥
190ºC). Replace the lubricant and grease soon after first 200 hrs running, and replace
yet again following a moth managing. Afterwards, exchange the lubricant and grease according to the
setting and lubricant (grease) quality propose a suitable EPT for a few
(five) Often verify the inlet air filter, clean or replace the filter in time.
(6) Blower overload occasionally not immediately displayed, so spend attention to
the ingestion and exhaust force, bearing temperature and the recent boost traits
of motor to establish no matter whether the blower operates typically
(7) Prior to disassembling the blower, the assembling relation and proportions
should be recorded or measured, make marks on elements to make sure the original
demands after assembling.
(eight) When freshly equipment or overhaul, the oil tank should be cleaned just before use
and propose change all grease after 8 hours managing.

Common failure purpose and troubleshooting

No Failure Achievable motives Elimination methods
one Friction
in between the
(one) Impurities on the impeller,
resulting in the hole is too tiny
(two) Equipment use, resulting in a
large backlash
(three) The gear is not well set,
can not preserve the impeller
(4) Bearing put on resulting in
clearance escalating.
(1) Take away dust and examine
no matter whether there is injury parts
(two) Adjust the equipment gap, change
the gears if the gear backlash is
better than the typical 30% to
(3)Re-assemble the gears, hold
the taper get in touch with region is to seventy five%
(four)Substitute the bearing
two Collision
impeller and
wall, the
impeller prime
and casing
(1) Installation hole is not correct
(2) operating pressure is as well
large, exceeding the specified
(3) Running temperature is also higher
(4) Casing or base deformation,
positioning admirer failure
(five) Bearing axial spot is not very good
(one) Modify the gap
(2) Identify leads to of
overloading, decreased the strain
to the specified price
(3) Examine the installation
accuracy and lessen the pipe
(4) Check and fix bearings,
and to ensure the clearance
3 Temperature
way too high
(one) Oil in tank is also considerably, also
thick or way too dirty
(two) Filter or silencer is blocked
(3)The pressure is increased than
the specified value
(four)Too much use of the
impeller, huge hole
(5)Poor ventilation, indoor
temperature is substantial, resulting in
inlet air’s high temperature
(six) The rotating speed is too low,outcome in the belt slipping.
(one)Reduce the oil degree or rely on
(2)Take away of blocking objects
(3)Reducing the strain through
the blower
(four)Mend its clearance
(five)Open up vents to decrease room
(6) Boost velocity to stop the
belt slipping.
4 Insufficient
(1) The inlet filter is blocked
(two) Impeller use and the gap
will increase too much
(three) Belt slipping
(4) Massive imports pressure reduction
(five) Pipeline air flow leakage
(1) Clear the filter dust and
(two) Fix the gap
(3)Tighten the belt and improve
the number of belts
(four)Adjust the inlet strain to the
specified value
(five) Check out and restore the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Higher tank situation lead to
leakage from the discharge port
(two) Seal dress in, ensuing in shaft oil spills
(three) The strain is greater than
the specified value

(1)Lessen the oil degree
(two)Exchange the seals
(3)Clear the air vents, 2mm diameter faucet is fixed in the
center chamber, open the faucet
underneath the wall
six Irregular
vibration and
(one)Bearing clearance exceeds the
specified benefit or bearing use
(two) The gear backlash is also
big, not in a restricted fastened
(three) The foreign objects and dust
brought on by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation caused the collision
triggered by overload,
(5) Friction in between the impeller
and the inlet housing brought on by

circumstance is damaged
(4)Examine the again strain, check
the wheel and alter gap
(5)Check out the filter and back again
pressure, improve the hole
among the impeller inlet and the
(6)Cleanse the impeller and the
casing, to make sure that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the base.
7 Motor
(one)In contrast with the needed
strain, the force difference
is massive that the back pressure or
the inlet stress is large
(two) Compared with the
tools specifications, blower
stream is too huge, so its pressure
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating components
(5) The oil stage is too higher
(six) Slim V-belt is overheat,
vibration is way too large, or pulley
is way too small
(1) Decrease the pressure to the
specified benefit
(two) Exhaust the extra gas into
the ambiance or minimize the
blower speed
(three) Take away the obstructions
(four)Quickly shut down, check out
the reason
(five) Alter the oil to the right
(six) Check the belt tension, and
replaced it with huge diameter
