The doing work principle of the a few-blade roots blower: two 3-lobed rotors are arranged 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 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 obtain the
goal of blowing.

Feature of our roots blower:
1. Large adjustment of the air quantity
2. Reduced Noise
three. Higher performance
4. Reduced energy cosumption
five. Long time life
6. Dependable working, easy routine maintenance,tiny footprint

The Software of the Roots Blower

Servicing and inspection
(one) Check all fasteners and locating pins conditions whether or not they are loosening.
(two) Usually verify whether or not the leakage phenomenon of the body.
(3) Spend focus to lubrication, volume of grease and noises when running,
determine regardless of whether it functions below the needed circumstances.
(four) CZPT & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop stage ≥
190ºC). Exchange the lubricant and grease right after first two hundred hrs running, and change
once again after a moth managing. Later, exchange the lubricant and grease in accordance to the
surroundings and lubricant (grease) top quality propose a suited substitute for three
months.
(5) Usually check out the inlet air filter, clean or change the filter in time.
(6) Blower overload often not immediately exhibited, so spend consideration to
the ingestion and exhaust pressure, bearing temperature and the existing boost traits
of motor to establish no matter whether the blower functions typically
(seven) Ahead of disassembling the blower, the assembling relation and dimensions
must be recorded or calculated, make marks on factors to make sure the CZPT
demands right after assembling.
(8) When newly machine or overhaul, the oil tank ought to be cleaned before use
and suggest exchange all grease right after eight hours working.

Common failure explanation and troubleshooting

No Failure Feasible reasons Elimination approaches
1 Friction
between the
impeller
(one) Impurities on the impeller,
ensuing in the gap is also little
(two) Equipment dress in, resulting in a
big backlash
(3) The gear is not effectively set,
can not maintain the impeller
synchronization
(four) Bearing dress in ensuing in
clearance escalating.
(one) Get rid of filth and check
whether or not there is harm areas
(two) Modify the gear gap, change
the gears if the gear backlash is
better than the regular 30% to
50%
(three)Re-assemble the gears, maintain
the taper get in touch with area is to seventy five%
(four)Substitute the bearing
two Collision
among
impeller and
wall, the
impeller top
and casing
(1) Installation hole is not appropriate
(two) functioning force is also
higher, exceeding the specified
price
(three) Functioning temperature is as well high
(four) Casing or base deformation,
positioning admirer failure
(five) Bearing axial place is not great
(one) Alter the hole
(two) Determine brings about of
overloading, reduced the pressure
to the specified price
(3) Examine the installation
accuracy and decrease the pipe
rigidity
(four) Verify and mend bearings,
and to make sure the clearance
(5)Relocation
3 Temperature
also high
(1) Oil in tank is too considerably, too
thick or too filthy
(two) CZPT or silencer is blocked
(three)The pressure is larger than
the specified worth
(four)Too much wear of the
impeller, large gap
(five)Bad ventilation, indoor
temperature is higher, ensuing in
inlet air’s substantial temperature
(six) The rotating pace is too low,result in the belt slipping.
(one)Reduce the oil amount or rely on
oil
(2)Remove of blocking objects
(three)Minimizing the force by means of
the blower
(four)Repair its clearance
(five)Open up vents to lessen place
temperature
(six) Boost speed to prevent the
belt slipping.
four Insufficient
stream
(1) The inlet filter is blocked
(2) Impeller dress in and the gap
increases way too significantly
(three) Belt slipping
(4) Massive imports pressure loss
(5) CZPT air flow leakage
(1) Clear the filter dust and
obstruction
(2) Mend the hole
(3)Tighten the belt and improve
the quantity of belts
(four)Modify the inlet force to the
specified price
(five) Examine and repair the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(one)Substantial tank situation result in
leakage from the discharge port
(2) Seal dress in, ensuing in shaft oil spills
(3) The force is higher than
the specified benefit

 
(1)Decrease the oil level
(two)Change the seals
(three)Distinct the air vents, 2mm diameter faucet is fixed in the
middle chamber, open the faucet
below the wall
6 Irregular
vibration and
noise
(one)Bearing clearance exceeds the
specified benefit or bearing wear
(two) The equipment backlash is also
huge, not in a limited mounted
(3) The foreign objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation brought on the collision
induced by overload,
(five) Friction among the impeller
and the inlet housing caused by
overheating
(6) Unbalance of the impeller
brought on by fouling or international
body
(seven) CZPT bolts or other
fasteners are loosened
(1)Exchange bearings or bearing
seat
(2)Reassemble equipment and make sure
backlash
(3)Cleansing blower, check out the
circumstance is destroyed
(4)Check the again stress, examine
the wheel and change gap
(five)Check out the filter and again
stress, boost the gap
amongst the impeller inlet and the
casing
(six)Clear the impeller and the
casing, to guarantee that the impeller
clearance operate
(7) Tighten the anchor bolts and
leveling the base.
seven Motor
overload
(1)When compared with the needed
strain, the strain big difference
is big that the again strain or
the inlet strain is substantial
(2) When compared with the
products requirements, blower
flow is too huge, so its strain
will increase
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating elements
(five) The oil level is way too large
(six) Slim V-belt is overheat,
vibration is also big, or pulley
is also modest
(one) Decrease the force to the
specified price
(2) Exhaust the surplus gas into
the ambiance or lessen the
blower velocity
(three) Eliminate the obstructions
(four)Right away shut down, examine
the explanation
(five) Adjust the oil to the appropriate
level
(6) Check the belt pressure, and
replaced it with massive diameter
pulley.
