The working theory of the 3-blade roots blower: two a few-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on both 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 gas in the chamber is pushed to obtain the
purpose of blowing.

Characteristic of our roots blower:
one. Massive adjustment of the air volume
2. Minimal Noise
3. Higher performance
four. Reduced vitality cosumption
5. Extended time daily life
6. Trustworthy operating, effortless servicing,small footprint

The Software of the Roots Blower

Maintenance and inspection
(one) Examine all fasteners and locating pins circumstances whether or not they are loosening.
(2) Always verify whether or not the leakage phenomenon of the physique.
(3) Spend consideration to lubrication, sum of grease and noises when managing,
figure out whether or not it functions beneath the required problems.
(4) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash stage ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop stage ≥
190ºC). Replace the lubricant and grease after 1st two hundred several hours running, and replace
once more following a moth managing. Later on, change the lubricant and grease according to the
atmosphere and lubricant (grease) quality propose a suited EPT for a few
(5) Usually examine the inlet air filter, cleanse or replace the filter in time.
(6) Blower overload at times not immediately displayed, so pay out attention to
the consumption and exhaust strain, bearing temperature and the recent increase traits
of motor to establish regardless of whether the blower operates typically
(7) Just before disassembling the blower, the assembling relation and dimensions
have to be recorded or measured, make marks on factors to make certain the original
requirements right after assembling.
(8) When recently device or overhaul, the oil tank ought to be cleaned prior to use
and suggest replace all grease after eight several hours operating.

Typical failure cause and troubleshooting

No Failure Attainable motives Elimination strategies
one Friction
among the
(one) Impurities on the impeller,
resulting in the hole is too tiny
(2) Gear dress in, resulting in a
huge backlash
(3) The equipment is not nicely set,
can not preserve the impeller
(four) Bearing put on ensuing in
clearance rising.
(one) Take away dirt and verify
regardless of whether there is hurt elements
(two) Alter the gear hole, exchange
the gears if the equipment backlash is
increased than the typical 30% to
(three)Re-assemble the gears, hold
the taper get in touch with location is to seventy five%
(4)Change the bearing
two Collision
impeller and
wall, the
impeller best
and casing
(1) Set up gap is not appropriate
(two) running strain is too
high, exceeding the specified
(3) Functioning temperature is way too higher
(four) Casing or base deformation,
positioning admirer failure
(five) Bearing axial area is not good
(one) Alter the gap
(two) Determine triggers of
overloading, reduced the pressure
to the specified value
(3) Check the installation
accuracy and minimize the pipe
(four) Check and fix bearings,
and to make certain the clearance
three Temperature
too substantial
(one) Oil in tank is as well a lot, too
thick or as well dirty
(2) Filter or silencer is blocked
(3)The pressure is greater than
the specified value
(4)Extreme wear of the
impeller, big gap
(5)Bad air flow, indoor
temperature is large, ensuing in
inlet air’s substantial temperature
(six) The rotating pace is way too minimal,result in the belt slipping.
(one)Reduce the oil level or rely on
(2)Eliminate of blocking objects
(3)Lowering the strain through
the blower
(4)Restore its clearance
(5)Open vents to decrease room
(six) Enhance pace to avert the
belt slipping.
four Inadequate
(1) The inlet filter is blocked
(2) Impeller put on and the hole
increases as well much

center chamber, open up the faucet
under the wall
six Irregular
vibration and
(one)Bearing clearance exceeds the
specified price or bearing wear
(2) The gear backlash is as well

casing, to make sure that the impeller
clearance work
(seven) Tighten the anchor bolts and
leveling the foundation.
seven Motor
(one)In comparison with the essential
force, the strain variation
is large that the back pressure or
the inlet pressure is high
(two) In contrast with the
equipment requirements, blower
stream is too big, so its pressure
(three)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating elements
(5) The oil amount is too large
(6) Slim V-belt is overheat,
vibration is too huge, or pulley
is way too little
(one) Reduce the stress to the
specified worth
(2) Exhaust the extra fuel into
the ambiance or lessen the
blower pace
(three) Eliminate the obstructions
(four)Immediately shut down, examine
the purpose
(5) Adjust the oil to the correct
(6) Check out the belt pressure, and
replaced it with massive diameter
