The operating 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 each sides of the cavity. Through the motion 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 obtain the
function of blowing.

The Software of the Roots Blower

Servicing and inspection
(1) Check out all fasteners and finding pins problems no matter whether they are loosening.
(two) Always verify whether the leakage phenomenon of the human body.
(three) Pay out attention to lubrication, quantity of grease and noises when managing,
determine whether it performs underneath the necessary situations.
(4) CZPT & 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 point ≥
190ºC). Substitute the lubricant and grease after initial 200 several hours managing, and substitute
yet again soon after a moth running. Afterwards, change the lubricant and grease according to the
setting and lubricant (grease) top quality propose a ideal substitution for 3
months.
(five) Often check the inlet air filter, clear or exchange the filter in time.
(six) Blower overload sometimes not instantly exhibited, so pay consideration to
the ingestion and exhaust force, bearing temperature and the present enhance tendencies
of motor to figure out whether the blower works typically
(seven) Just before disassembling the blower, the assembling relation and dimensions
need to be recorded or measured, make marks on parts to guarantee the CZPT
requirements after assembling.
(eight) When recently device or overhaul, the oil tank need to be cleaned prior to use
and propose substitute all grease right after eight several hours running.

Widespread failure cause and troubleshooting

No Failure Achievable causes Elimination techniques
one Friction
between the
impeller
(one) Impurities on the impeller,
resulting in the hole is also little
(2) Equipment use, resulting in a
large backlash
(three) The gear is not effectively fastened,
can not keep the impeller
synchronization
(four) Bearing use resulting in
clearance increasing.
(1) Eliminate grime and check
whether or not there is hurt areas
(2) Adjust the gear hole, exchange
the gears if the gear backlash is
better than the average 30% to
fifty%
(3)Re-assemble the gears, hold
the taper contact location is to seventy five%
(four)Exchange the bearing
2 Collision
in between
impeller and
wall, the
impeller prime
and casing
(1) Set up hole is not right
(2) functioning force is also
higher, exceeding the specified
price
(three) Working temperature is way too higher
(4) Casing or base deformation,
positioning admirer failure
(5) Bearing axial spot is not good
(1) Adjust the gap
(2) Discover triggers of
overloading, reduced the pressure
to the specified benefit
(three) Check the installation
accuracy and lessen the pipe
tension
(four) Verify and repair bearings,
and to guarantee the clearance
(5)Relocation
three Temperature
as well large
(1) Oil in tank is way too a lot, as well
thick or too dirty
(two) CZPT or silencer is blocked
(three)The force is larger than
the specified value
(4)Too much use of the
impeller, huge gap
(five)Bad air flow, indoor
temperature is large, resulting in
inlet air’s large temperature
(6) The rotating speed is as well minimal,outcome in the belt slipping.
(one)Decrease the oil stage or depend on
oil
(2)Get rid of of blocking objects
(three)Decreasing the stress by means of
the blower
(4)Mend its clearance
(5)Open vents to lessen place
temperature
(six) Increase speed to avert the
belt slipping.
4 Inadequate
circulation
(1) The inlet filter is blocked
(2) Impeller wear and the gap
boosts also much
(3) Belt slipping
(four) Large imports force reduction
(5) CZPT air flow leakage
(1) Clean the filter dust and
obstruction
(2) Fix the gap
(three)Tighten the belt and enhance
the variety of belts
(four)Adjust the inlet stress to the
specified value
(5) Check out and mend the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(one)High tank situation lead to
leakage from the discharge port
(2) Seal wear, ensuing in shaft oil spills
(three) The pressure is higher than
the specified worth

 
(one)Reduce the oil amount
(two)Replace the seals
(3)Obvious the air vents, 2mm diameter faucet is mounted in the
center chamber, open the faucet
underneath the wall
6 Irregular
vibration and
noise
(one)Bearing clearance exceeds the
specified worth or bearing wear
(2) The gear backlash is too
large, not in a limited fastened
(three) The overseas objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation brought on the collision
brought on by overload,
(5) Friction between the impeller
and the inlet housing caused by
overheating
(six) Unbalance of the impeller
brought on by fouling or foreign
body
(7) CZPT bolts or other
fasteners are loosened
(one)Exchange bearings or bearing
seat
(2)Reassemble gear and guarantee
backlash
(three)Cleaning blower, check out the
case is destroyed
(four)Check the again force, check
the wheel and adjust hole
(5)Examine the filter and again
stress, increase the hole
between the impeller inlet and the
casing
(six)Clean the impeller and the
casing, to make certain that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the foundation.
7 Motor
overload
(1)When compared with the essential
stress, the force big difference
is massive that the again stress or
the inlet pressure is substantial
(2) In comparison with the
gear specifications, blower
flow is also big, so its stress
boosts
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (caught)
rotating parts
(5) The oil level is also large
(6) Slim V-belt is overheat,
vibration is too huge, or pulley
is too modest
(1) Lessen the pressure to the
specified price
(2) Exhaust the excessive gasoline into
the environment or lessen the
blower velocity
(3) Eliminate the obstructions
(4)Instantly shut down, check
the cause
(five) Adjust the oil to the proper
stage
(six) Examine the belt rigidity, and
changed it with huge diameter
pulley.
