The working theory of the 3-blade roots blower: two 3-lobed rotors are arranged 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 opposite 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 obtain the
objective of blowing.

Function of our roots blower:
one. Huge adjustment of the air volume
2. Lower Sound
three. Higher effectiveness
four. Lower energy cosumption
five. Long time life
six. Reliable managing, simple routine maintenance,little footprint

The Software of the Roots Blower

Upkeep and inspection
(one) Check out all fasteners and finding pins problems regardless of whether they are loosening.
(2) Often verify whether the leakage phenomenon of the physique.
(3) Pay attention to lubrication, quantity of grease and noises when running,
determine regardless of whether it performs below the essential conditions.
(4) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop level ≥
190ºC). Replace the lubricant and grease after 1st 200 hrs running, and change
again following a moth working. Later on, exchange the lubricant and grease in accordance to the
atmosphere and lubricant (grease) high quality propose a ideal EPT for three
months.
(5) Constantly examine the inlet air filter, clean or exchange the filter in time.
(six) Blower overload sometimes not immediately shown, so pay out focus to
the consumption and exhaust strain, bearing temperature and the existing boost trends
of motor to figure out regardless of whether the blower functions generally
(seven) Before disassembling the blower, the assembling relation and proportions
should be recorded or measured, make marks on components to make sure the unique
demands following assembling.
(eight) When recently equipment or overhaul, the oil tank need to be cleaned just before use
and propose replace all grease following 8 hrs working.

Typical failure cause and troubleshooting

No Failure Attainable motives Elimination approaches
1 Friction
in between the
impeller
(one) Impurities on the impeller,
ensuing in the hole is too tiny
(two) Gear dress in, resulting in a
huge backlash
(three) The equipment is not effectively set,
can not maintain the impeller
synchronization
(4) Bearing wear ensuing in
clearance increasing.
(one) Take away dust and examine
whether or not there is damage components
(2) Adjust the gear gap, replace
the gears if the equipment backlash is
better than the average thirty% to
fifty%
(three)Re-assemble the gears, keep
the taper speak to spot is to 75%
(4)Change the bearing
2 Collision
between
impeller and
wall, the
impeller top
and casing
(one) Set up hole is not appropriate
(two) functioning pressure is as well
higher, exceeding the specified
value
(three) Operating temperature is way too higher
(4) Casing or base deformation,
positioning supporter failure
(five) Bearing axial place is not excellent
(1) Modify the hole
(2) Determine brings about of
overloading, diminished the strain
to the specified value
(3) Check the installation
precision and reduce the pipe
stress
(4) Verify and restore bearings,
and to make certain the clearance
(5)Relocation
three Temperature
too high
(one) Oil in tank is as well a lot, as well
thick or also filthy
(2) Filter or silencer is blocked
(three)The stress is larger than
the specified benefit
(4)Excessive use of the
impeller, massive gap
(five)Poor air flow, indoor
temperature is large, resulting in
inlet air’s large temperature
(6) The rotating pace is also reduced,result in the belt slipping.
(one)Minimize the oil stage or rely on
oil
(two)Remove of blocking objects
(3)Decreasing the strain by way of
the blower
(4)Fix its clearance
(five)Open vents to decrease area
temperature
(six) Boost velocity to stop the
belt slipping.

increases also much
(3) Belt slipping
(4) Big imports strain reduction
(five) Pipeline air flow leakage
(one) Clean the filter dust and
obstruction
(2) Mend the gap
(three)Tighten the belt and enhance
the variety of belts
(4)Change the inlet force to the
specified worth
(five) Check and restore the pipeline
five Oil leaking or
oil leaking

(three)Clear the air vents, 2mm diameter faucet is fastened in the
center chamber, open up the faucet
below the wall
6 Abnormal
vibration and
noise
(one)Bearing clearance exceeds the
specified value or bearing use
(2) The equipment backlash is way too
huge, not in a restricted mounted
(3) The foreign objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation caused the collision

the wheel and alter hole
(five)Check the filter and back
strain, enhance the hole
amongst the impeller inlet and the
casing
(six)Cleanse the impeller and the
casing, to guarantee that the impeller
clearance perform
(7) Tighten the anchor bolts and
leveling the foundation.
seven Motor
overload
(1)Compared with the required
pressure, the force distinction
is huge that the back pressure or
the inlet force is higher
(two) In comparison with the
tools requirements, blower
movement is also large, so its force
raises
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (trapped)
rotating elements
(five) The oil level is way too substantial
(six) Slender V-belt is overheat,
vibration is also huge, or pulley
is as well little
(1) Reduce the pressure to the
specified price
(two) Exhaust the extra gas into
the environment or decrease the
blower velocity
(three) Remove the obstructions
(4)Instantly shut down, examine
the reason
