The operating principle of the a few-blade roots blower: two a few-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 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 gasoline in the chamber is pushed to achieve the
function of blowing.

Feature of our roots blower:
one. Huge adjustment of the air volume

The Software of the Roots Blower

Servicing and inspection
(1) Check out all fasteners and locating pins conditions whether or not they are loosening.
(2) Always check whether or not the leakage phenomenon of the human body.
(three) Pay out interest to lubrication, sum of grease and noises when managing,
establish whether or not it operates below the necessary circumstances.
(4) CZPT & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall position ≥
190ºC). Change the lubricant and grease after 1st two hundred hours managing, and replace
yet again right after a moth working. Afterwards, replace the lubricant and grease in accordance to the
surroundings and lubricant (grease) quality suggest a ideal alternative for a few
months.
(five) Constantly verify the inlet air filter, cleanse or exchange the filter in time.
(6) Blower overload sometimes not quickly exhibited, so pay out consideration to
the intake and exhaust force, bearing temperature and the existing increase developments
of motor to establish whether or not the blower functions typically
(seven) Just before disassembling the blower, the assembling relation and dimensions
must be recorded or calculated, make marks on components to make certain the CZPT
needs after assembling.
(8) When freshly equipment or overhaul, the oil tank should be cleaned before use
and propose replace all grease right after 8 hours operating.

Widespread failure reason and troubleshooting

No Failure Attainable causes Elimination approaches
one Friction
among the
impeller
(1) Impurities on the impeller,
ensuing in the hole is as well tiny
(2) Gear dress in, resulting in a
big backlash
(3) The gear is not nicely mounted,
can not preserve the impeller
synchronization
(four) Bearing dress in resulting in
clearance increasing.
(1) Take away dust and check out
no matter whether there is harm parts
(2) Change the equipment gap, replace
the gears if the equipment backlash is
higher than the average 30% to
fifty%
(3)Re-assemble the gears, keep
the taper speak to area is to 75%
(four)Replace the bearing
2 Collision
between
impeller and
wall, the
impeller best
and casing
(one) Set up hole is not right
(2) working stress is also
high, exceeding the specified
benefit
(three) Operating temperature is way too high
(four) Casing or base deformation,
positioning admirer failure
(5) Bearing axial area is not great
(one) Modify the hole
(2) Discover leads to of
overloading, lowered the strain
to the specified value
(three) Verify the installation
precision and reduce the pipe
tension
(4) Verify and repair bearings,
and to guarantee the clearance
(five)Relocation
three Temperature
too large
(one) Oil in tank is way too a lot, way too
thick or too filthy
(2) CZPT or silencer is blocked
(three)The pressure is larger than
the specified benefit
(4)Excessive put on of the
impeller, huge gap
(five)Bad ventilation, indoor
temperature is substantial, resulting in
inlet air’s high temperature
(6) The rotating pace is way too lower,end result in the belt slipping.
(1)Lessen the oil amount or count on
oil
(two)Take away of blocking objects
(three)Minimizing the strain through
the blower
(four)Repair its clearance
(5)Open up vents to lessen place
temperature
(6) Boost speed to stop the
belt slipping.
4 Insufficient
flow
(one) The inlet filter is blocked
(two) Impeller put on and the gap
raises way too much
(3) Belt slipping
(four) Big imports strain loss
(five) CZPT ventilation leakage
(1) Clean the filter dust and
obstruction
(two) Fix the hole
(3)Tighten the belt and improve
the variety of belts
(4)Alter the inlet force to the
specified worth
(five) Verify and fix the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(one)High tank place result in
leakage from the discharge port
(2) Seal put on, resulting in shaft oil spills
(3) The pressure is higher than
the specified benefit

 
(1)Minimize the oil degree
(two)Substitute the seals
(3)Clear the air vents, 2mm diameter faucet is set in the
center chamber, open the faucet
below the wall
six Abnormal
vibration and
sound
(1)Bearing clearance exceeds the
specified value or bearing put on
(2) The gear backlash is as well
huge, not in a limited set
(three) The international objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation caused the collision
triggered by overload,
(five) Friction amongst the impeller
and the inlet housing brought on by
overheating
(6) Unbalance of the impeller
caused by fouling or international
physique
(7) CZPT bolts or other
fasteners are loosened
(1)Substitute bearings or bearing
seat
(2)Reassemble gear and guarantee
backlash
(three)Cleansing blower, examine the
situation is damaged
(4)Check the back again force, examine
the wheel and modify gap
(five)Check the filter and back
pressure, boost the gap
among the impeller inlet and the
casing
(six)Thoroughly clean the impeller and the
casing, to make sure that the impeller
clearance perform
(7) Tighten the anchor bolts and
leveling the foundation.
seven Motor
overload
(one)In comparison with the needed
force, the stress difference
is huge that the back stress or
the inlet strain is high
(2) When compared with the
products demands, blower
circulation is also huge, so its pressure
boosts
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (stuck)
rotating components
(5) The oil degree is as well high
(6) Slender V-belt is overheat,
vibration is as well massive, or pulley
is way too tiny
(one) Reduce the force to the
specified value
(two) Exhaust the extra fuel into
the environment or lessen the
blower speed
(3) Remove the obstructions
(four)Immediately shut down, examine
the purpose
(five) Modify the oil to the right
degree
(6) Check out the belt stress, and
replaced it with large diameter
pulley.
