The operating basic 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 the two sides of the cavity. By way of the motion of a pair of
synchronous gears, the two rotors rotate in reverse 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 attain the
function of blowing.

Attribute of our roots blower:
one. Big adjustment of the air quantity
two. Minimal Sound
3. Large performance
four. Minimal vitality cosumption
five. Long time daily life
six. Dependable managing, straightforward servicing,tiny footprint

The Application of the Roots Blower

Upkeep and inspection
(1) Check all fasteners and finding pins situations whether they are loosening.
(2) Always check regardless of whether the leakage phenomenon of the entire body.
(three) Pay focus to lubrication, quantity of grease and noises when operating,
decide regardless of whether it performs beneath the necessary conditions.
(4) CZPT & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall level ≥
190ºC). Replace the lubricant and grease soon after first 200 several hours operating, and replace
yet again soon after a moth running. Afterwards, substitute the lubricant and grease according to the
atmosphere and lubricant (grease) good quality suggest a appropriate substitute for three
(five) Always verify the inlet air filter, cleanse or change the filter in time.
(six) Blower overload at times not right away exhibited, so spend focus to
the intake and exhaust pressure, bearing temperature and the current improve tendencies
of motor to figure out regardless of whether the blower functions generally
(7) Prior to disassembling the blower, the assembling relation and proportions
must be recorded or calculated, make marks on parts to make sure the CZPT
demands right after assembling.
(8) When recently device or overhaul, the oil tank must be cleaned prior to use
and suggest exchange all grease following eight hours operating.

Typical failure purpose and troubleshooting

No Failure Achievable factors Elimination methods
1 Friction
between the
(one) Impurities on the impeller,
resulting in the gap is as well small
(2) Gear put on, ensuing in a
huge backlash
(3) The equipment is not well fastened,
can not keep the impeller
(four) Bearing wear resulting in
clearance growing.
(one) Eliminate dirt and check
no matter whether there is hurt areas
(2) Change the equipment hole, substitute
the gears if the gear backlash is
greater than the common 30% to
(3)Re-assemble the gears, hold
the taper speak to area is to 75%
(four)Change the bearing
2 Collision
impeller and
wall, the
impeller prime
and casing
(one) Installation gap is not right
(2) operating stress is also
higher, exceeding the specified
(three) Running temperature is also large
(4) Casing or base deformation,
positioning enthusiast failure
(5) Bearing axial spot is not great
(one) Change the hole
(two) Recognize brings about of
overloading, decreased the force
to the specified worth
(3) Check out the set up
accuracy and decrease the pipe
(4) Verify and fix bearings,
and to make certain the clearance
3 Temperature
as well high
(one) Oil in tank is too significantly, too
thick or also filthy
(2) CZPT or silencer is blocked
(3)The force is larger than
the specified worth
(4)Excessive use of the
impeller, huge gap
(5)Bad ventilation, indoor
temperature is higher, resulting in
inlet air’s higher temperature
(6) The rotating velocity is also reduced,consequence in the belt slipping.
(1)Lessen the oil amount or count on
(2)Eliminate of blocking objects
(three)Reducing the pressure by way of
the blower
(four)Repair its clearance
(5)Open up vents to lessen area
(6) Improve pace to stop the
belt slipping.
four Inadequate
(1) The inlet filter is blocked
(two) Impeller dress in and the hole
increases as well a lot
(three) Belt slipping
(4) Big imports strain decline
(five) CZPT ventilation leakage
(one) Clear the filter dust and
(2) Restore the hole
(3)Tighten the belt and boost
the amount of belts
(4)Adjust the inlet force to the
specified price
(five) Check and repair the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(one)Large tank place lead to
leakage from the discharge port

middle chamber, open the faucet
beneath the wall
6 Irregular
vibration and
(one)Bearing clearance exceeds the
specified price or bearing wear
(two) The equipment backlash is also
huge, not in a restricted 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 induced the collision
brought on by overload,

situation is broken
(4)Check out the back pressure, check
the wheel and modify gap
(5)Check the filter and back
stress, enhance the hole
between the impeller inlet and the
(6)Clear the impeller and the
casing, to guarantee that the impeller
clearance function
(7) Tighten the anchor bolts and
leveling the base.
seven Motor
(1)When compared with the necessary
pressure, the stress variation
is massive that the again pressure or
the inlet force is high
(two) Compared with the
gear requirements, blower
stream is as well massive, so its strain
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (trapped)
rotating components
(five) The oil degree is also substantial
(six) Narrow V-belt is overheat,
vibration is too huge, or pulley
is way too little
(1) Minimize the stress to the
specified benefit
(two) Exhaust the excessive gas into
the environment or reduce the
blower pace
(3) Eliminate the obstructions
(four)Immediately shut down, check
the explanation
