The functioning theory of the 3-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. By way of the motion of a pair of
synchronous gears, the two rotors rotate in reverse directions 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
function of blowing.

Function of our roots blower:
one. Large adjustment of the air quantity
two. Minimal Noise
3. Large efficiency
four. Lower strength cosumption
5. Lengthy time life
6. Trustworthy working, effortless servicing,modest footprint

The Software of the Roots Blower

Routine maintenance and inspection
(one) Examine all fasteners and locating pins problems whether they are loosening.
(2) Often check out no matter whether the leakage phenomenon of the entire body.
(three) Pay out interest to lubrication, volume of grease and noises when managing,
establish whether or not it functions under the required situations.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (artificial lithium grease penetration 220-250, fall level ≥
190ºC). Substitute the lubricant and grease right after very first two hundred several hours operating, and substitute
once more soon after a moth managing. Later on, replace the lubricant and grease according to the
atmosphere and lubricant (grease) high quality propose a appropriate EPT for a few
(five) Always verify the inlet air filter, cleanse or change the filter in time.
(six) Blower overload often not immediately shown, so spend focus to
the consumption and exhaust stress, bearing temperature and the current improve trends
of motor to determine regardless of whether the blower operates usually
(7) Before disassembling the blower, the assembling relation and dimensions
have to be recorded or measured, make marks on components to make certain the unique
demands soon after assembling.
(eight) When freshly machine or overhaul, the oil tank ought to be cleaned ahead of use
and propose exchange all grease right after eight hours managing.

Widespread failure cause and troubleshooting

No Failure Achievable factors Elimination approaches
1 Friction
among the
(1) Impurities on the impeller,
resulting in the hole is also modest
(two) Gear wear, ensuing in a
huge backlash
(3) The equipment is not properly mounted,
can not keep the impeller
(four) Bearing use resulting in
clearance increasing.
(1) Eliminate filth and check
whether or not there is harm parts
(two) Alter the equipment gap, exchange
the gears if the gear backlash is
higher than the typical 30% to
(3)Re-assemble the gears, hold
the taper speak to area is to seventy five%
(four)Substitute the bearing
two Collision
impeller and
wall, the
impeller prime
and casing
(1) Set up gap is not correct
(two) running pressure is also
substantial, exceeding the specified
(three) Operating temperature is also high
(four) Casing or foundation deformation,
positioning supporter failure
(five) Bearing axial place is not very good
(one) Modify the gap
(2) Discover triggers of
overloading, lowered the force
to the specified benefit
(3) Check the installation
precision and decrease the pipe
(four) Check and restore bearings,
and to ensure the clearance
3 Temperature
also large
(1) Oil in tank is as well considerably, as well
thick or also filthy
(two) Filter or silencer is blocked
(3)The pressure is larger than
the specified price
(four)Extreme put on of the
impeller, large gap
(5)Very poor ventilation, indoor
temperature is substantial, ensuing in
inlet air’s substantial temperature
(6) The rotating pace is too lower,end result in the belt slipping.
(1)Minimize the oil level or rely on
(two)Take away of blocking objects
(three)Reducing the strain through
the blower
(4)Fix its clearance
(5)Open vents to decrease area
(six) Increase speed to stop the
belt slipping.
4 Insufficient
(1) The inlet filter is blocked
(2) Impeller wear and the hole
raises way too considerably
(three) Belt slipping
(four) Huge imports pressure reduction
(five) Pipeline ventilation leakage
(1) Cleanse the filter dust and
(2) Fix the hole
(3)Tighten the belt and increase
the amount of belts
(four)Adjust the inlet stress to the
specified price
(5) Check out and mend the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Higher tank situation cause
leakage from the discharge port
(two) Seal put on, ensuing in shaft oil spills
(three) The force is greater than
the specified value

(1)Reduce the oil stage
(two)Substitute the seals
(3)Distinct the air vents, 2mm diameter faucet is mounted in the
middle chamber, open up the faucet
beneath the wall
6 Abnormal
vibration and
(one)Bearing clearance exceeds the
specified value or bearing dress in
(2) The equipment backlash is too
huge, not in a tight fastened
(three) 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
caused by overload,
(5) Friction among the impeller
and the inlet housing induced by
(six) Unbalance of the impeller
brought on by fouling or international
human body
(7) Anchor bolts or other
fasteners are loosened
(1)Replace bearings or bearing
(2)Reassemble gear and guarantee
(3)Cleansing blower, check the
case is broken
(four)Examine the back force, verify
the wheel and modify hole
(five)Check out the filter and back again
strain, boost the hole
amongst the impeller inlet and the
(six)Cleanse the impeller and the
casing, to make certain that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the foundation.
7 Motor
(one)When compared with the essential
stress, the stress difference
is big that the back again force or
the inlet pressure is high
(two) Compared with the
gear demands, blower
stream is too massive, so its force
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating components
(five) The oil amount is too large
(six) Slim V-belt is overheat,
vibration is way too huge, or pulley
is as well small
(one) Decrease the strain to the
specified price
(two) Exhaust the surplus fuel into
the ambiance or reduce the
blower speed
(3) Eliminate the obstructions
(4)Quickly shut down, examine
the reason
(five) Modify the oil to the correct
(6) Verify the belt pressure, and
changed it with huge diameter
