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
(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
(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
(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
(three)Re-assemble the gears, keep
the taper speak to spot is to 75%
(4)Change the bearing
2 Collision
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
(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
(4) Verify and restore bearings,
and to make certain the clearance
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.

casing, to guarantee that the impeller
clearance perform
(7) Tighten the anchor bolts and
leveling the foundation.
seven Motor
(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
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (trapped)
rotating elements
