The functioning theory of the three-blade roots blower: two three-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on the two sides of the cavity. Through the action 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 obtain the
function of blowing.

Characteristic of our roots blower:
1. Massive adjustment of the air volume
two. Minimal Sounds
3. High performance
4. Lower vitality cosumption
5. Long time life
6. Trustworthy operating, easy maintenance,small footprint

The Application of the Roots Blower

Upkeep and inspection
(1) Verify all fasteners and locating pins circumstances no matter whether they are loosening.
(2) Usually check whether the leakage phenomenon of the body.
(3) Shell out focus to lubrication, sum of grease and noises when managing,
determine regardless of whether it functions below the required circumstances.
(4) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop point ≥
190ºC). Substitute the lubricant and grease after very first two hundred hours managing, and substitute
again soon after a moth running. Later on, change the lubricant and grease in accordance to the
surroundings and lubricant (grease) top quality suggest a suitable EPT for 3
months.
(five) Always examine the inlet air filter, thoroughly clean or exchange the filter in time.
(6) Blower overload often not quickly displayed, so shell out attention to
the ingestion and exhaust stress, bearing temperature and the existing boost trends
of motor to decide regardless of whether the blower performs typically
(seven) Just before disassembling the blower, the assembling relation and dimensions
have to be recorded or calculated, make marks on components to make certain the first
needs after assembling.
(eight) When freshly device or overhaul, the oil tank must be cleaned prior to use
and suggest exchange all grease soon after 8 several hours operating.

Common failure reason and troubleshooting

No Failure Achievable motives Elimination techniques
one Friction
in between the
impeller
(1) Impurities on the impeller,
ensuing in the gap is also tiny
(2) Equipment dress in, ensuing in a
huge backlash
(3) The equipment is not effectively mounted,
can not maintain the impeller
synchronization
(4) Bearing put on ensuing in
clearance escalating.
(1) Remove filth and verify
no matter whether there is injury areas
(2) Change the gear gap, exchange
the gears if the gear backlash is
greater than the typical thirty% to
fifty%
(3)Re-assemble the gears, maintain
the taper get in touch with region is to seventy five%
(four)Substitute the bearing
two Collision
amongst
impeller and
wall, the
impeller top
and casing
(1) Set up hole is not appropriate
(two) operating force is way too
substantial, exceeding the specified
benefit
(3) Functioning temperature is also large
(four) Casing or base deformation,
positioning supporter failure
(5) Bearing axial location is not great
(1) Modify the hole
(2) Identify brings about of
overloading, decreased the stress
to the specified worth
(three) Check the set up
accuracy and decrease the pipe
tension
(four) Verify and repair bearings,
and to guarantee the clearance
(five)Relocation
three Temperature
too high
(one) Oil in tank is also much, as well
thick or too soiled
(two) Filter or silencer is blocked
(3)The pressure is higher than
the specified benefit
(4)Too much use of the
impeller, large hole
(five)Inadequate ventilation, indoor
temperature is substantial, resulting in
inlet air’s substantial temperature
(6) The rotating speed is also lower,outcome in the belt slipping.
(one)Decrease the oil degree or count on
oil
(2)Take away of blocking objects
(three)Minimizing the strain by means of
the blower
(4)Restore its clearance
(5)Open vents to decrease area
temperature
(six) Increase speed to stop the
belt slipping.
four Inadequate
flow
(1) The inlet filter is blocked
(2) Impeller put on and the gap
increases as well a lot
(three) Belt slipping
(four) Large imports pressure decline
(five) Pipeline ventilation leakage
(1) Thoroughly clean the filter dust and
obstruction
(two) Repair the gap
(3)Tighten the belt and improve
the variety of belts
(4)Change the inlet strain to the
specified value
(5) Check and repair the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Large tank situation result in
leakage from the discharge port
(2) Seal put on, ensuing in shaft oil spills
(3) The force is higher than
the specified value

(2)Exchange the seals
(three)Very clear the air vents, 2mm diameter faucet is fixed in the
middle chamber, open the faucet
below the wall
six Irregular
vibration and
noise
(one)Bearing clearance exceeds the
specified price or bearing use
(two) The gear backlash is also
massive, not in a restricted fastened
(three) The overseas objects and dust
caused by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft

fasteners are loosened
(1)Replace bearings or bearing
seat
(two)Reassemble equipment and make sure
backlash
(3)Cleansing blower, verify the
situation is broken
(four)Verify the back again strain, verify
the wheel and modify hole
(5)Check the filter and back
force, enhance the hole
in between the impeller inlet and the
casing
(6)Thoroughly clean the impeller and the
casing, to guarantee that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the base.
seven Motor
overload
(one)Compared with the essential
stress, the strain big difference
is huge that the back pressure or
the inlet force is substantial
(two) Compared with the
gear needs, blower
stream is way too big, so its pressure
boosts
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (stuck)
rotating elements
(five) The oil level is as well high
(six) Slim V-belt is overheat,
vibration is too huge, or pulley
is way too modest
(1) Decrease the force to the
specified benefit
(two) Exhaust the extra fuel into
the environment or minimize the
blower velocity
(three) Remove the obstructions
(4)Immediately shut down, verify
the purpose
(five) Adjust the oil to the appropriate
amount
(6) Check out the belt tension, and
changed it with big diameter
pulley.
