The functioning principle of the three-blade roots blower: two three-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on each sides of the cavity. Through the action 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 attain the
goal of blowing.

Feature of our roots blower:
one. Massive adjustment of the air quantity
2. Low Sounds
three. Higher performance
four. Lower power cosumption
5. Lengthy time daily life
6. Trustworthy working, simple upkeep,tiny footprint

The Application of the Roots Blower

Upkeep and inspection
(one) Check all fasteners and finding pins situations no matter whether they are loosening.
(two) Usually check out whether the leakage phenomenon of the body.
(3) Spend interest to lubrication, volume of grease and noises when managing,
figure out no matter whether it functions below the needed situations.
(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 (artificial lithium grease penetration 220-250, fall level ≥
190ºC). Exchange the lubricant and grease right after 1st two hundred hours managing, and substitute
yet again following a moth working. Later on, exchange the lubricant and grease according to the
surroundings and lubricant (grease) high quality suggest a appropriate EPT for three
(five) Always examine the inlet air filter, clean or exchange the filter in time.
(6) Blower overload occasionally not immediately displayed, so pay out interest to
the intake and exhaust stress, bearing temperature and the recent increase trends
of motor to decide no matter whether the blower performs usually
(seven) Prior to disassembling the blower, the assembling relation and proportions
need to be recorded or calculated, make marks on elements to make sure the first
requirements after assembling.
(8) When newly device or overhaul, the oil tank should be cleaned prior to use
and propose exchange all grease following 8 several hours managing.

Widespread failure purpose and troubleshooting

No Failure Achievable factors Elimination strategies
one Friction
among the
(1) Impurities on the impeller,
ensuing in the gap is also little
(2) Gear use, ensuing in a
big backlash
(three) The equipment is not properly mounted,
can not keep the impeller
(four) Bearing put on ensuing in
clearance rising.
(one) Remove filth and verify
whether there is damage elements
(two) Modify the gear gap, exchange
the gears if the equipment backlash is
higher than the average thirty% to
(three)Re-assemble the gears, preserve
the taper get in touch with region is to seventy five%
(4)Exchange the bearing
two Collision
impeller and
wall, the
impeller leading
and casing
(1) Installation hole is not correct
(2) working strain is too
higher, exceeding the specified
(3) Running temperature is too substantial
(4) Casing or foundation deformation,
positioning enthusiast failure
(5) Bearing axial place is not great
(1) Modify the hole
(two) Identify triggers of
overloading, diminished the force
to the specified price
(3) Check the installation
accuracy and reduce the pipe
(four) Verify and restore bearings,
and to ensure the clearance
three Temperature
too high
(1) Oil in tank is too significantly, also
thick or too dirty
(2) Filter or silencer is blocked
(three)The force is increased than
the specified worth
(4)Too much put on of the
impeller, massive hole
(five)Bad air flow, indoor
temperature is substantial, resulting in
inlet air’s high temperature
(six) The rotating velocity is way too reduced,outcome in the belt slipping.
(one)Minimize the oil degree or depend on
(two)Eliminate of blocking objects
(3)Decreasing the force by way of
the blower
(4)Restore its clearance
(5)Open up vents to decrease space
(6) Enhance pace to avert the
belt slipping.
4 Insufficient
(one) The inlet filter is blocked
(2) Impeller wear and the hole
will increase too considerably
(three) Belt slipping
(4) Massive imports force decline
(five) Pipeline ventilation leakage
(1) Thoroughly clean the filter dust and
(2) Mend the gap
(three)Tighten the belt and enhance
the amount of belts
(4)Modify the inlet stress to the
specified benefit
(five) Check out and repair the pipeline
5 Oil leaking or
oil leaking
into the enclosure
(one)Higher tank place cause
leakage from the discharge port
(2) Seal dress in, ensuing in shaft oil spills
(3) The strain is larger than
the specified value

(1)Lessen the oil level
(two)Replace the seals
(three)Clear the air vents, 2mm diameter faucet is set in the
center chamber, open up the faucet
underneath the wall
6 Abnormal
vibration and
(1)Bearing clearance exceeds the
specified benefit or bearing wear
(two) The gear backlash is way too
massive, not in a restricted set
(three) The overseas objects and dust
caused by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation triggered the collision
brought on by overload,
(five) Friction amongst the impeller
and the inlet housing triggered by
(six) Unbalance of the impeller
triggered by fouling or foreign
human body
(7) Anchor bolts or other
fasteners are loosened
(one)Change bearings or bearing
(two)Reassemble gear and make sure
(three)Cleaning blower, verify the
scenario is ruined
(4)Check the back stress, examine
the wheel and modify gap
(5)Examine the filter and back again
stress, increase the gap
among the impeller inlet and the
(6)Thoroughly clean the impeller and the
casing, to ensure that the impeller
clearance function
(seven) Tighten the anchor bolts and
leveling the foundation.
7 Motor
(1)Compared with the required
pressure, the strain difference
is massive that the back again pressure or
the inlet stress is higher
(2) In contrast with the
tools needs, blower
stream is too large, so its stress
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating elements
(five) The oil degree is way too large
(six) Slim V-belt is overheat,
vibration is also large, or pulley
is also tiny
(1) Decrease the force to the
specified worth
(2) Exhaust the surplus gas into
the atmosphere or minimize the
blower velocity
(3) Get rid of the obstructions
(4)Instantly shut down, check out
the explanation
(5) Change the oil to the proper
(six) Examine the belt rigidity, and
replaced it with big diameter
