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 the two sides of the cavity. By means of the motion of a pair of
synchronous gears, the two rotors rotate in opposite 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 accomplish the
function of blowing.

Attribute of our roots blower:
1. Huge adjustment of the air volume
2. Minimal Noise
three. High effectiveness
four. Lower strength cosumption
five. Long time daily life
six. Dependable running, simple servicing,small footprint

with several scientific research units, colleges and universities at home and abroad. We also constantly consider to
absorb and increase the domestic innovative production technologies, so as to advertise the upgrading and
optimization of the product and make the item good quality reach the innovative degree at property and overseas.
ESR -kind Roots Blower consists of several collection these kinds of as Three-leaves Sort, Two-leaves Type and Centrifugal
Type,which can be additional divided to hundreds of varieties. The items are widely utilized in sewage remedy,
pneumatic conveying,vacuum packaging, aquaculture, food processing, EPT electricity, petrochemical, cement,
mining and other industries. Our items have this sort of positive aspects as lower sound, vitality saving, secure good quality,
and lengthy service existence, etc.. With the revenue outlets throughout the domestic capital metropolitan areas, our items sell well all
over the region, and have been exported to North The us,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other countries. Having received the ISO9001 International Top quality Program Certification, we have
established and enhanced the quality assurance of the goods planning, manufacturing, and set up.

The Application of the Roots Blower

Routine maintenance and inspection
(one) Examine all fasteners and locating pins problems whether or not they are loosening.
(2) Constantly check no matter whether the leakage phenomenon of the entire body.
(three) Pay out consideration to lubrication, sum of grease and noises when running,
determine whether it works beneath the needed 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 (artificial lithium grease penetration 220-250, drop stage ≥
190ºC). Substitute the lubricant and grease after initial two hundred hours working, and change
again following a moth operating. Later, replace the lubricant and grease according to the
surroundings and lubricant (grease) top quality suggest a appropriate EPT for a few
(five) Always verify the inlet air filter, clear or change the filter in time.
(6) Blower overload often not immediately exhibited, so pay interest to
the intake and exhaust stress, bearing temperature and the present increase tendencies
of motor to determine no matter whether the blower works normally
(7) Ahead of disassembling the blower, the assembling relation and dimensions
should be recorded or calculated, make marks on components to ensure the unique
needs following assembling.
(eight) When recently device or overhaul, the oil tank must be cleaned before use
and suggest substitute all grease soon after 8 several hours managing.

Widespread failure purpose and troubleshooting

No Failure Possible causes Elimination strategies
one Friction
among the
(1) Impurities on the impeller,
resulting in the gap is as well tiny
(2) Equipment put on, resulting in a
big backlash
(three) The equipment is not effectively set,
can not sustain the impeller
(4) Bearing wear resulting in
clearance growing.
(1) Eliminate dust and check out
no matter whether there is hurt elements
(two) Modify the equipment gap, change
the gears if the gear backlash is
greater than the average 30% to
(three)Re-assemble the gears, preserve
the taper get in touch with location is to seventy five%
(four)Exchange the bearing
two Collision
impeller and
wall, the
impeller best
and casing
(one) Set up gap is not appropriate
(two) working force is too
high, exceeding the specified
(three) Operating temperature is as well large
(4) Casing or foundation deformation,
positioning fan failure
(5) Bearing axial location is not good
(1) Adjust the gap
(2) Discover brings about of
overloading, lowered the pressure
to the specified worth
(three) Verify the set up
precision and minimize the pipe
(four) Verify and restore bearings,
and to make sure the clearance
three Temperature
too large
(1) Oil in tank is way too a lot, way too
thick or too dirty
(two) Filter or silencer is blocked
(three)The force is larger than
the specified worth
(four)Extreme dress in of the
impeller, big hole
(5)Poor ventilation, indoor
temperature is high, resulting in
inlet air's high temperature
(six) The rotating velocity is too lower,outcome in the belt slipping.
(one)Reduce the oil level or count on
(2)Remove of blocking objects
(3)Reducing the force by way of
the blower
(four)Restore its clearance
(5)Open up vents to lessen space
(6) Enhance velocity to stop the
belt slipping.
4 Insufficient
(1) The inlet filter is blocked
(2) Impeller put on and the gap
raises too much
(three) Belt slipping
(4) Massive imports stress loss
(five) Pipeline ventilation leakage
(1) Clean the filter dust and
(two) Fix the gap
(3)Tighten the belt and improve
the quantity of belts
(4)Change the inlet force to the
specified value
(5) Examine and restore the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)Substantial tank place result in
leakage from the discharge port
(2) Seal dress in, ensuing in shaft oil spills
(three) The stress is higher than
the specified value

(1)Decrease the oil stage
(2)Substitute the seals
(three)Clear the air vents, 2mm diameter faucet is fixed in the
middle chamber, open the faucet
underneath the wall
six Abnormal
vibration and
(one)Bearing clearance exceeds the
specified benefit or bearing wear
(two) The gear backlash is way too
big, not in a tight fastened
(three) The international objects and dust
triggered by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation triggered the collision
induced by overload,
(5) Friction in between the impeller
and the inlet housing caused by
(6) Unbalance of the impeller
triggered by fouling or international
(seven) Anchor bolts or other
fasteners are loosened
(1)Replace bearings or bearing
(2)Reassemble equipment and ensure
(3)Cleansing blower, check the
situation is broken
(four)Check out the back strain, check out
the wheel and modify gap
(5)Examine the filter and back
stress, boost the hole
among the impeller inlet and the
(6)Thoroughly clean the impeller and the
casing, to guarantee that the impeller
clearance operate
(7) Tighten the anchor bolts and
leveling the foundation.
7 Motor
(1)When compared with the required
strain, the force variation
is large that the again strain or
the inlet force is large
(two) When compared with the
gear demands, blower
movement is also large, so its stress
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(four) Collusion or friction (stuck)
rotating parts
(five) The oil stage is way too high
(6) Slender V-belt is overheat,
vibration is as well massive, or pulley
is as well modest
(1) Decrease the strain to the
specified worth
(two) Exhaust the surplus fuel into
the environment or decrease the
blower speed
(3) Eliminate the obstructions
(four)Instantly shut down, check
the explanation
(5) Alter the oil to the appropriate
(six) Check the belt pressure, and
replaced it with massive diameter
