The functioning principle of the three-blade roots blower: two 3-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Via the motion of a pair of
synchronous gears, the two rotors rotate in reverse instructions and Relying on the mutual engagement of the two
rotors, the suction port and the discharge port are isolated, and the fuel in the chamber is pushed to achieve the
objective of blowing.

Feature of our roots blower:
one. Huge adjustment of the air quantity
two. Lower Noise
3. Large efficiency
four. Reduced energy cosumption
five. Long time lifestyle
six. Reputable operating, easy routine maintenance,modest footprint

The Software of the Roots Blower

Upkeep and inspection
(one) Check out all fasteners and locating pins situations no matter whether they are loosening.
(2) Often check no matter whether the leakage phenomenon of the body.
(three) Pay attention to lubrication, quantity of grease and noises when managing,
establish whether it functions underneath the necessary situations.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, drop position ≥
190ºC). Substitute the lubricant and grease soon after first two hundred hrs working, and substitute
once more after a moth running. Later, replace the lubricant and grease according to the
environment and lubricant (grease) good quality propose a ideal substitution for three
(5) Always check the inlet air filter, cleanse or change the filter in time.
(six) Blower overload sometimes not quickly displayed, so pay consideration to
the intake and exhaust pressure, bearing temperature and the current improve traits
of motor to establish regardless of whether the blower functions typically
(seven) Ahead of disassembling the blower, the assembling relation and proportions
need to be recorded or measured, make marks on elements to ensure the CZPT
demands right after assembling.
(eight) When newly device or overhaul, the oil tank ought to be cleaned ahead of use
and suggest change all grease after eight several hours running.

Widespread failure purpose and troubleshooting

No Failure Achievable causes Elimination techniques
1 Friction
between the
(1) Impurities on the impeller,
ensuing in the gap is too small
(2) Gear dress in, ensuing in a
big backlash
(three) The gear is not well set,
can not preserve the impeller
(four) Bearing use resulting in
clearance growing.
(1) Eliminate filth and verify
no matter whether there is harm components
(2) Alter the equipment gap, change
the gears if the equipment backlash is
better than the common 30% to
(three)Re-assemble the gears, keep
the taper contact location is to seventy five%
(four)Exchange the bearing
2 Collision
in between
impeller and
wall, the
impeller prime
and casing
(one) Installation hole is not proper
(two) operating strain is also
higher, exceeding the specified
(3) Operating temperature is as well high
(four) Casing or foundation deformation,
positioning admirer failure
(five) Bearing axial area is not good
(one) Modify the hole
(2) Discover brings about of
overloading, decreased the pressure
to the specified worth
(3) Check out the set up
precision and decrease the pipe
(four) Verify and mend bearings,
and to make sure the clearance
three Temperature
also high
(1) Oil in tank is as well much, too
thick or as well filthy
(two) CZPT or silencer is blocked
(3)The strain is greater than
the specified value
(4)Abnormal wear of the
impeller, big hole
(5)Inadequate air flow, indoor
temperature is higher, resulting in
inlet air’s higher temperature
(6) The rotating speed is also low,consequence in the belt slipping.
(one)Lessen the oil level or count on
(2)Eliminate of blocking objects
(3)Lowering the force through
the blower
(4)Restore its clearance
(5)Open vents to reduce room
(6) Enhance speed to avoid the
belt slipping.
4 Insufficient
(one) The inlet filter is blocked
(two) Impeller dress in and the hole
increases also much
(3) Belt slipping
(4) Massive imports stress decline
(five) Pipeline air flow leakage
(one) Clear the filter dust and
(two) Restore the hole
(three)Tighten the belt and increase
the variety of belts
(4)Change the inlet strain to the
specified value
(5) Check out and repair the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Higher tank place result in
leakage from the discharge port
(2) Seal use, resulting in shaft oil spills
(3) The force is greater than
the specified value

(one)Minimize the oil level
(two)Substitute the seals
(three)Very clear the air vents, 2mm diameter faucet is set in the
center chamber, open up the faucet
under the wall
six Abnormal
vibration and
(1)Bearing clearance exceeds the
specified value or bearing wear
(two) The equipment backlash is way too
massive, not in a limited fastened
(three) The overseas objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation caused the collision
induced by overload,
(five) Friction in between the impeller
and the inlet housing triggered by
(6) Unbalance of the impeller
brought on by fouling or foreign
(7) Anchor bolts or other
fasteners are loosened
(one)Substitute bearings or bearing
(2)Reassemble equipment and make sure
(3)Cleaning blower, check the
scenario is destroyed
(4)Examine the again pressure, examine
the wheel and modify hole
(five)Check out the filter and again
strain, enhance the hole
among the impeller inlet and the
(six)Clean the impeller and the
casing, to guarantee that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the base.
seven Motor
(1)Compared with the necessary
force, the force variation
is big that the again pressure or
the inlet stress is substantial
(2) In comparison with the
products needs, blower
movement is as well large, so its force
will increase
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating components
(5) The oil stage is way too large
(6) Narrow V-belt is overheat,
vibration is also massive, or pulley
is way too little
(one) Decrease the strain to the
specified worth
(2) Exhaust the extra gasoline into
the ambiance or minimize the
blower speed
(3) Remove the obstructions
(4)Instantly shut down, check
the purpose
(5) Change the oil to the proper
(six) Check out the belt rigidity, and
changed it with big diameter
