The doing work basic principle of the 3-blade roots blower: two a few-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on both 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 fuel in the chamber is pushed to attain the
purpose of blowing.

Feature of our roots blower:
one. Huge adjustment of the air volume
2. Reduced Sound
three. Higher efficiency
four. Lower strength cosumption
five. Long time lifestyle
6. Trustworthy operating, straightforward servicing,little footprint

The Application of the Roots Blower

Maintenance and inspection
(one) Verify all fasteners and finding pins circumstances regardless of whether they are loosening.
(two) Constantly verify regardless of whether the leakage phenomenon of the human body.
(3) Pay out interest to lubrication, amount of grease and noises when managing,
figure out whether or not it functions under the required conditions.
(four) CZPT & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall position ≥
190ºC). Change the lubricant and grease after 1st two hundred several hours working, and substitute
yet again following a moth operating. Later, exchange the lubricant and grease in accordance to the
surroundings and lubricant (grease) high quality propose a suitable alternative for 3
(5) Often verify the inlet air filter, clean or change the filter in time.
(6) Blower overload sometimes not right away displayed, so shell out interest to
the intake and exhaust stress, bearing temperature and the recent enhance trends
of motor to establish no matter whether the blower operates usually
(seven) Ahead of disassembling the blower, the assembling relation and proportions
should be recorded or measured, make marks on factors to guarantee the CZPT
specifications right after assembling.
(eight) When newly equipment or overhaul, the oil tank must be cleaned just before use
and propose substitute all grease following eight hours running.

Common failure cause and troubleshooting

No Failure Achievable causes Elimination techniques
one Friction
among the
(1) Impurities on the impeller,
ensuing in the hole is too small
(2) Equipment dress in, ensuing in a
huge backlash
(3) The equipment is not well mounted,
can not maintain the impeller
(4) Bearing use resulting in
clearance growing.
(1) Get rid of grime and examine
whether or not there is hurt areas
(2) Change the gear gap, replace
the gears if the equipment backlash is
better than the typical thirty% to
(3)Re-assemble the gears, maintain
the taper make contact with region is to 75%
(four)Change the bearing
two Collision
in between
impeller and
wall, the
impeller best
and casing
(1) Installation gap is not proper
(two) running stress is way too
high, exceeding the specified
(3) Running temperature is as well high
(4) Casing or base deformation,
positioning fan failure
(five) Bearing axial area is not good
(1) Adjust the gap
(2) Discover causes of
overloading, diminished the force
to the specified value
(3) Check the installation
precision and lessen the pipe
(four) Check out and repair bearings,
and to guarantee the clearance
three Temperature
also substantial
(one) Oil in tank is as well a lot, also
thick or too dirty
(2) CZPT or silencer is blocked
(three)The pressure is larger than
the specified benefit
(four)Extreme dress in of the
impeller, massive gap
(5)Very poor ventilation, indoor
temperature is high, ensuing in
inlet air’s large temperature
(6) The rotating velocity is too lower,end result in the belt slipping.
(1)Reduce the oil stage or rely on
(2)Remove of blocking objects
(three)Lowering the pressure by way of
the blower
(4)Repair its clearance
(5)Open vents to reduce place

casing, to make sure that the impeller
clearance perform
(7) Tighten the anchor bolts and
leveling the base.
seven Motor
(one)In contrast with the required
pressure, the force big difference
is huge that the again stress or
the inlet strain is higher
(2) Compared with the
tools demands, blower
stream is way too large, so its force
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (stuck)
rotating components
(five) The oil degree is as well substantial
(six) Slender V-belt is overheat,
vibration is also large, or pulley
is as well little
