The working basic principle of the 3-blade roots blower: two a few-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on each sides of the cavity. By means of the action of a pair of
synchronous gears, the two rotors rotate in opposite 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 attain the
objective of blowing.

Attribute of our roots blower:
one. Big adjustment of the air quantity
2. Low Sounds
3. Higher effectiveness
4. Minimal strength cosumption
5. Extended time lifestyle
six. Reliable managing, easy upkeep,small footprint

The Application of the Roots Blower

Routine maintenance and inspection
(one) Check out all fasteners and finding pins circumstances whether they are loosening.
(2) Always check out no matter whether the leakage phenomenon of the body.
(three) Shell out consideration to lubrication, amount of grease and noises when managing,
figure out whether it operates beneath the essential problems.
(four) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop point ≥
190ºC). Substitute the lubricant and grease after first two hundred hrs working, and change
once more after a moth running. Later on, change the lubricant and grease according to the
environment and lubricant (grease) quality suggest a suitable EPT for three
(5) Usually check the inlet air filter, cleanse or exchange the filter in time.
(6) Blower overload occasionally not instantly shown, so spend attention to
the intake and exhaust strain, bearing temperature and the current enhance traits
of motor to decide whether or not the blower functions normally
(7) Just before disassembling the blower, the assembling relation and proportions
must be recorded or calculated, make marks on factors to ensure the unique
requirements after assembling.
(8) When recently device or overhaul, the oil tank need to be cleaned ahead of use
and suggest substitute all grease after eight hrs managing.

Common failure reason and troubleshooting

No Failure Achievable motives Elimination methods
1 Friction
among the
(one) Impurities on the impeller,
resulting in the hole is as well small
(two) Equipment wear, ensuing in a
massive backlash
(three) The equipment is not nicely fastened,
can not maintain the impeller
(four) Bearing use ensuing in
clearance growing.
(1) Get rid of grime and verify
whether or not there is damage elements
(2) Change the gear hole, replace
the gears if the gear backlash is
increased than the common thirty% to
(three)Re-assemble the gears, maintain
the taper contact spot is to seventy five%
(four)Change the bearing
two Collision
impeller and
wall, the
impeller leading
and casing
(one) Set up gap is not correct
(two) functioning stress is way too
higher, exceeding the specified
(3) Functioning temperature is way too substantial
(four) Casing or base deformation,
positioning admirer failure
(five) Bearing axial place is not very good
(one) Change the hole
(two) Recognize leads to of
overloading, decreased the stress
to the specified price
(3) Check out the set up
accuracy and minimize the pipe
(4) Examine and repair bearings,
and to make certain the clearance
three Temperature
as well large
(1) Oil in tank is as well much, as well
thick or way too soiled
(2) Filter or silencer is blocked
(three)The pressure is increased than
the specified worth
(4)Excessive dress in of the
impeller, massive gap
(5)Bad air flow, indoor
temperature is higher, resulting in
inlet air’s high temperature
(six) The rotating pace is also minimal,result in the belt slipping.
(one)Minimize the oil degree or depend on
(two)Get rid of of blocking objects
(three)Minimizing the pressure by way of
the blower
