The working basic principle of the three-blade roots blower: two a few-lobed rotors are organized in the cavity, and the
suction port and the discharge port are opened on equally sides of the cavity. Via 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 gas in the chamber is pushed to obtain the
function of blowing.

Function of our roots blower:
1. Massive adjustment of the air quantity
2. Lower Sound
three. Higher efficiency
four. Low vitality cosumption
5. Extended time lifestyle
6. Reputable managing, easy upkeep,little footprint

The Software of the Roots Blower

Servicing and inspection
(one) Check out all fasteners and locating pins problems no matter whether they are loosening.
(two) Usually examine whether or not the leakage phenomenon of the entire body.
(three) Pay out focus to lubrication, quantity of grease and noises when running,
determine regardless of whether it works underneath the essential conditions.
(four) Lubricant & grease: The lubricant is for medium load industrial gear oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall point ≥
190ºC). Replace the lubricant and grease following initial 200 hrs managing, and substitute
again following a moth running. Later, replace the lubricant and grease in accordance to the
environment and lubricant (grease) quality suggest a ideal EPT for three
(five) Always check the inlet air filter, thoroughly clean or exchange the filter in time.
(6) Blower overload occasionally not quickly displayed, so pay out interest to
the ingestion and exhaust strain, bearing temperature and the existing increase trends
of motor to decide no matter whether the blower performs generally
(seven) Ahead of disassembling the blower, the assembling relation and dimensions
have to be recorded or measured, make marks on factors to guarantee the original
requirements soon after assembling.
(eight) When newly equipment or overhaul, the oil tank ought to be cleaned ahead of use
and propose exchange all grease right after 8 several hours managing.

Frequent failure explanation and troubleshooting

No Failure Achievable motives Elimination approaches
1 Friction
in between the
(1) Impurities on the impeller,
resulting in the hole is too modest
(two) Gear dress in, resulting in a
massive backlash
(three) The gear is not well fixed,
can not sustain the impeller
(4) Bearing dress in resulting in
clearance increasing.
(1) Remove dirt and verify
regardless of whether there is damage areas
(2) Alter the gear gap, exchange
the gears if the equipment backlash is
increased than the common 30% to
(3)Re-assemble the gears, maintain
the taper speak to location is to 75%
(four)Exchange the bearing
two Collision
impeller and
wall, the
impeller prime
and casing
(1) Installation hole is not proper
(two) operating force is way too
large, exceeding the specified
(three) Operating temperature is too substantial
(4) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial spot is not great
(one) Modify the hole
(two) Identify causes of
overloading, lowered the force
to the specified worth
(three) Verify the installation
precision and decrease the pipe
(4) Verify and fix bearings,
and to guarantee the clearance
3 Temperature
too substantial
(1) Oil in tank is also significantly, also
thick or too dirty
(2) Filter or silencer is blocked
(3)The force is higher than
the specified worth
(4)Abnormal wear of the
impeller, massive hole
(five)Inadequate air flow, indoor
temperature is large, ensuing in
inlet air's higher temperature
(six) The rotating pace is way too minimal,consequence in the belt slipping.
(one)Minimize the oil amount or count on
(two)Take away of blocking objects
(three)Decreasing the stress via
the blower
(four)Mend its clearance
(five)Open vents to lessen place
(six) Boost pace to prevent the
belt slipping.
4 Inadequate
(1) The inlet filter is blocked
(two) Impeller wear and the gap
will increase too much
(three) Belt slipping
(four) Large imports force loss
(5) Pipeline ventilation leakage
(1) Clear the filter dust and
(2) Restore the gap
(three)Tighten the belt and increase
the amount of belts
(4)Adjust the inlet strain to the
specified price
(5) Check out and restore the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Substantial tank situation lead to
leakage from the discharge port
(2) Seal put on, resulting in shaft oil spills
(three) The pressure is higher than
the specified price

(one)Reduce the oil amount
(2)Replace the seals
(three)Very clear the air vents, 2mm diameter faucet is fastened in the
middle chamber, open up the faucet
beneath the wall
six Abnormal
vibration and
(1)Bearing clearance exceeds the
specified price or bearing wear
(2) The gear backlash is way too
massive, not in a limited mounted
(three) The international objects and dust
caused by the impeller and the
impeller, the impeller and the
housing collision
(four) the impeller shaft
deformation induced the collision
triggered by overload,
(5) Friction in between the impeller
and the inlet housing caused by
(six) Unbalance of the impeller
caused by fouling or international
(seven) Anchor bolts or other
fasteners are loosened
(one)Change bearings or bearing
(two)Reassemble gear and make sure
(3)Cleansing blower, check out the
situation is damaged
(four)Verify the back again force, check
the wheel and modify gap
(five)Check out the filter and again
strain, enhance the hole
between the impeller inlet and the
(6)Thoroughly clean the impeller and the
casing, to make certain that the impeller
clearance work
(7) Tighten the anchor bolts and
leveling the base.
7 Motor
(1)In contrast with the essential
strain, the strain difference
is large that the back strain or
the inlet stress is large
(2) When compared with the
gear needs, blower
circulation is also large, so its stress
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (trapped)
rotating components
(5) The oil degree is as well substantial
(6) Narrow V-belt is overheat,
vibration is also large, or pulley
is way too little
(one) Lessen the strain to the
specified worth
(2) Exhaust the excessive gasoline into
the ambiance or reduce the
blower speed
(3) Get rid of the obstructions
(four)Immediately shut down, check
the explanation
(five) Adjust the oil to the correct
(6) Examine the belt stress, and
replaced it with massive diameter
