The doing work principle of the 3-blade roots blower: two three-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on equally sides of the cavity. Through the action 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 gasoline in the chamber is pushed to accomplish the
goal of blowing.

Characteristic of our roots blower:
one. Huge adjustment of the air quantity
two. Minimal Sound
three. Substantial effectiveness
four. Minimal strength cosumption
5. Lengthy time daily life
six. Dependable running, straightforward routine maintenance,small footprint

The Application of the Roots Blower

Servicing and inspection
(1) Examine all fasteners and finding pins situations regardless of whether they are loosening.
(two) Constantly check whether or not the leakage phenomenon of the physique.
(three) Pay out consideration to lubrication, quantity of grease and noises when running,
determine no matter whether it functions beneath the required conditions.
(4) 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 (synthetic lithium grease penetration 220-250, fall position ≥
190ºC). Change the lubricant and grease following very first two hundred several hours managing, and change
once again right after a moth running. Afterwards, substitute the lubricant and grease in accordance to the
environment and lubricant (grease) high quality propose a appropriate alternative for 3
months.
(5) Constantly check out the inlet air filter, clean or substitute the filter in time.
(six) Blower overload occasionally not quickly shown, so pay attention to
the ingestion and exhaust pressure, bearing temperature and the present increase tendencies
of motor to figure out regardless of whether the blower functions normally
(7) Before disassembling the blower, the assembling relation and proportions
should be recorded or measured, make marks on parts to guarantee the CZPT
demands following assembling.
(8) When freshly machine or overhaul, the oil tank need to be cleaned just before use
and suggest change all grease right after eight hours operating.

Widespread failure explanation and troubleshooting

No Failure Possible motives Elimination techniques
1 Friction
among the
impeller
(one) Impurities on the impeller,
ensuing in the gap is as well little
(two) Gear wear, ensuing in a
big backlash
(3) The equipment is not properly fixed,
can not preserve the impeller
synchronization
(four) Bearing put on resulting in
clearance increasing.
(one) Eliminate dust and examine
whether or not there is hurt components
(2) Modify the gear hole, replace
the gears if the gear backlash is
better than the typical 30% to
50%
(three)Re-assemble the gears, maintain
the taper speak to location is to seventy five%
(four)Change the bearing
two Collision
amongst
impeller and
wall, the
impeller top
and casing
(one) Set up hole is not proper
(two) running stress is also
large, exceeding the specified
price
(3) Functioning temperature is too substantial
(four) Casing or base deformation,
positioning supporter failure
(5) Bearing axial place is not great
(one) Modify the hole
(2) Determine causes of
overloading, diminished the force
to the specified worth
(3) Examine the set up
precision and decrease the pipe
stress
(4) Examine and mend bearings,
and to make certain the clearance
(five)Relocation
3 Temperature
also substantial
(one) Oil in tank is way too a lot, way too
thick or too filthy
(2) CZPT or silencer is blocked
(three)The stress is increased than
the specified price
(4)Abnormal use of the
impeller, large gap
(5)Very poor ventilation, indoor
temperature is high, ensuing in
inlet air’s substantial temperature
(6) The rotating speed is as well low,result in the belt slipping.
(one)Minimize the oil level or depend on
oil
(2)Remove of blocking objects
(three)Minimizing the force by means of
the blower
(4)Restore its clearance
(five)Open vents to lessen area
temperature
(six) Improve speed to prevent the
belt slipping.
four Insufficient
movement
(one) The inlet filter is blocked
(two) Impeller use and the gap
raises way too a lot
(3) Belt slipping
(four) Massive imports force loss
(5) CZPT air flow leakage
(one) Clean the filter dust and
obstruction
(two) Restore the gap
(3)Tighten the belt and improve
the quantity of belts
(4)Alter the inlet stress to the
specified price
(five) Verify and repair the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)Large tank position cause
leakage from the discharge port
(two) Seal use, ensuing in shaft oil spills
(three) The pressure is larger than
the specified benefit

 
(1)Reduce the oil degree
(2)Change the seals
(three)Distinct the air vents, 2mm diameter faucet is fixed in the
middle chamber, open up the faucet
underneath the wall
6 Irregular
vibration and
sound
(1)Bearing clearance exceeds the
specified benefit or bearing dress in
(2) The equipment backlash is as well
massive, not in a limited set
(three) The international objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation brought on the collision
brought on by overload,
(5) Friction in between the impeller
and the inlet housing caused by
overheating
(6) Unbalance of the impeller
triggered by fouling or international
human body
(7) CZPT bolts or other
fasteners are loosened
(1)Substitute bearings or bearing
seat
(two)Reassemble gear and guarantee
backlash
(3)Cleaning blower, check out the
scenario is damaged
(4)Check the back again stress, verify
the wheel and alter gap
(5)Verify the filter and back again
force, boost the gap
in between the impeller inlet and the
casing
(6)Thoroughly clean the impeller and the
casing, to make sure that the impeller
clearance perform
(7) Tighten the anchor bolts and
leveling the base.
7 Motor
overload
(1)Compared with the necessary
force, the strain big difference
is big that the back force or
the inlet strain is substantial
(two) In comparison with the
gear requirements, blower
circulation is too large, so its pressure
increases
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (caught)
rotating elements
(5) The oil degree is also substantial
(six) Slim V-belt is overheat,
vibration is way too huge, or pulley
is as well little
(one) Decrease the force to the
specified price
(2) Exhaust the excessive gasoline into
the environment or reduce the
blower speed
(3) Take away the obstructions
(4)Quickly shut down, check
the purpose
(five) Adjust the oil to the right
level
(6) Verify the belt rigidity, and
replaced it with massive diameter
pulley.
