The working principle of the three-blade roots blower: two a few-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on each sides of the cavity. By means of the motion 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 gas in the chamber is pushed to obtain the
purpose of blowing.

Characteristic of our roots blower:
1. Huge adjustment of the air volume
two. Low Sounds
three. Higher performance
four. Lower energy cosumption
5. Lengthy time existence
6. Dependable working, simple maintenance,tiny footprint

The Application of the Roots Blower

Upkeep and inspection
(one) Verify all fasteners and locating pins situations no matter whether they are loosening.
(2) Constantly verify whether the leakage phenomenon of the human body.
(three) Shell out interest to lubrication, sum of grease and noises when working,
decide no matter whether it performs below the needed problems.
(four) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Change the lubricant and grease after 1st 200 hours working, and replace
once again following a moth managing. Later, substitute the lubricant and grease in accordance to the
surroundings and lubricant (grease) top quality suggest a suited EPT for a few
months.
(five) Usually check out the inlet air filter, clean or substitute the filter in time.
(6) Blower overload occasionally not immediately displayed, so spend interest to
the consumption and exhaust pressure, bearing temperature and the current improve developments
of motor to determine whether or not the blower performs typically
(seven) Just before disassembling the blower, the assembling relation and dimensions
should be recorded or calculated, make marks on parts to make sure the original
needs soon after assembling.
(8) When newly device or overhaul, the oil tank must be cleaned ahead of use
and propose substitute all grease after eight hours managing.

Frequent failure reason and troubleshooting

No Failure Possible reasons Elimination techniques
one Friction
among the
impeller
(one) Impurities on the impeller,
ensuing in the gap is also little
(two) Gear wear, ensuing in a
huge backlash
(3) The equipment is not effectively fastened,
can not sustain the impeller
synchronization
(four) Bearing dress in resulting in
clearance escalating.
(one) Remove grime and verify
whether there is harm areas
(two) Change the equipment hole, substitute
the gears if the equipment backlash is
higher than the regular thirty% to
50%
(three)Re-assemble the gears, keep
the taper get in touch with region is to 75%
(4)Change the bearing
2 Collision
in between
impeller and
wall, the
impeller top
and casing
(one) Installation gap is not appropriate
(two) functioning force is as well
large, exceeding the specified
worth
(3) Running temperature is as well high
(4) Casing or foundation deformation,
positioning supporter failure
(5) Bearing axial area is not very good
(one) Change the hole
(2) Identify causes of
overloading, diminished the force
to the specified worth
(three) Check out the installation
precision and minimize the pipe
tension
(4) Examine and mend bearings,
and to make certain the clearance
(five)Relocation
three Temperature
too large
(one) Oil in tank is way too much, way too
thick or too filthy
(two) Filter or silencer is blocked
(three)The stress is higher than
the specified benefit
(four)Abnormal dress in of the
impeller, huge hole
(5)Very poor air flow, indoor
temperature is high, resulting in
inlet air’s higher temperature
(6) The rotating velocity is also minimal,consequence in the belt slipping.
(1)Reduce the oil level or depend on
oil
(2)Eliminate of blocking objects
(3)Minimizing the pressure via
the blower
(4)Restore its clearance
(five)Open up vents to lessen space
temperature
(6) Enhance speed to stop the
belt slipping.
4 Inadequate
stream
(1) The inlet filter is blocked
(2) Impeller put on and the hole
boosts way too much
(3) Belt slipping
(4) Massive imports pressure decline
(five) Pipeline air flow leakage
(1) Clean the filter dust and
obstruction
(two) Repair the gap
(three)Tighten the belt and improve
the amount of belts
(four)Adjust the inlet strain to the
specified price
(five) Verify and mend the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(1)Substantial tank placement trigger
leakage from the discharge port
(2) Seal use, ensuing in shaft oil spills
(3) The strain is larger than
the specified benefit

 
(1)Lessen the oil degree

(3)Very clear the air vents, 2mm diameter faucet is set in the
middle chamber, open up the faucet
under the wall
six Irregular
vibration and
sound
(1)Bearing clearance exceeds the
specified value or bearing use
(2) The gear backlash is also
large, not in a tight fastened
(3) The international objects and dust
brought on by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation induced the collision

seat
(two)Reassemble equipment and make certain
backlash
(three)Cleaning blower, verify the
circumstance is ruined
(four)Check out the again stress, check out
the wheel and modify hole
(5)Check out the filter and back
pressure, boost the gap
among the impeller inlet and the
casing
(6)Cleanse the impeller and the
casing, to make sure that the impeller
clearance operate
(7) Tighten the anchor bolts and
leveling the base.
seven Motor
overload
(1)In comparison with the necessary
stress, the stress variation
is massive that the back again stress or
the inlet pressure is large
(two) In comparison with the
tools needs, blower
flow is too huge, so its stress
increases
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (trapped)
rotating areas
(five) The oil degree is too large
(6) Narrow V-belt is overheat,
vibration is also massive, or pulley
is too small
(1) Minimize the pressure to the
specified benefit
(two) Exhaust the excess fuel into
the environment or decrease the
blower pace
(3) Get rid of the obstructions
(4)Right away shut down, verify
the purpose
(5) Adjust the oil to the appropriate
amount
(6) Check out the belt stress, and
replaced it with massive diameter
pulley.
