The operating principle of the 3-blade roots blower: two three-lobed rotors are arranged 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 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.

Function of our roots blower:
1. Huge adjustment of the air volume
two. Minimal Noise
three. Substantial performance
4. Minimal vitality cosumption
5. Prolonged time life
six. Trustworthy running, straightforward servicing,little footprint

Our factory is a specialist producer of Roots blowers which has over twenty years’ experience in equipment
production. It is located in Xihu (West Lake) Dis. East Industrial Park, fifty kilometers to the east of Shan EPT provincial
cash— HangZhou. Our firm also has convenient targeted traffic transportation, as it is 15 kilometers absent from
Diaozhen Town station of HangZhou-HangZhou expressway, and 30 kilometers away from East HangZhou station of
ZheJiang -ZheJiang expressway.The foremost solution of our organization is ESR -variety Roots Blower. The roots
vacuum pump is a new kind of high-effectiveness roots blower, which is designed independently based on the
domestic and overseas sophisticated technologies. Several patented technologies have been adopted on Roots
Blower, and as a result we have produced important outcomes in strength conservation and noise reduction, etc.. So considerably, our
organization has invested much more than thirty,000,000 RMB to introduce such sophisticated professional tools as
horizontal machining middle, vertical machining middle, two-way CNC surface area planer, CNC lathe, CNC milling
machine, CNC planer, aircraft grinder, cylindrical grinding equipment, and a few coordinates screening device.
Besides, we have taken various measures to standardize the process stream these kinds of as working and cooperating
with a lot of scientific research units, faculties and universities at house and abroad. We also continuously try out to
soak up and increase the domestic sophisticated production systems, so as to advertise the upgrading and
optimization of the merchandise and make the product good quality attain the sophisticated stage at house and abroad.
ESR -variety Roots Blower consists of several collection this kind of as 3-leaves Kind, Two-leaves Variety and Centrifugal
Type,which can be even more divided to hundreds of versions. The items are extensively utilized in sewage therapy,
pneumatic conveying,vacuum packaging, aquaculture, food processing, EPT electrical power, petrochemical, cement,
mining and other industries. Our products have this sort of positive aspects as minimal sound, energy conserving, steady top quality,
and extended support existence, and many others.. With the sales outlets throughout the domestic funds cities, our goods offer effectively all
more than the region, and have been exported to North The united states,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other nations. Getting got the ISO9001 Global Quality System Certification, we have

The Application of the Roots Blower

Servicing and inspection
(one) Verify all fasteners and finding pins conditions no matter whether they are loosening.
(2) Usually check out whether or not the leakage phenomenon of the physique.
(3) Shell out interest to lubrication, volume of grease and noises when running,
figure out no matter whether it works below the needed circumstances.
(four) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop position ≥
190ºC). Exchange the lubricant and grease following first two hundred hrs managing, and change
yet again right after a moth working. Afterwards, replace the lubricant and grease according to the
atmosphere and lubricant (grease) top quality propose a suitable EPT for a few
(five) Always check out the inlet air filter, cleanse or exchange the filter in time.
(six) Blower overload sometimes not instantly shown, so spend interest to
the consumption and exhaust strain, bearing temperature and the current improve tendencies
of motor to establish whether the blower operates generally
(7) Ahead of disassembling the blower, the assembling relation and proportions
need to be recorded or measured, make marks on factors to make certain the authentic
demands soon after assembling.
(8) When recently device or overhaul, the oil tank must be cleaned ahead of use
and suggest exchange all grease soon after eight hrs operating.

Typical failure purpose and troubleshooting

No Failure Attainable motives Elimination approaches
1 Friction
amongst the
(one) Impurities on the impeller,
resulting in the hole is as well small
(2) Gear wear, ensuing in a
big backlash
(3) The gear is not nicely mounted,
can not preserve the impeller
(four) Bearing wear resulting in
clearance escalating.
(1) Get rid of dirt and verify
whether there is damage areas
(two) Change the equipment hole, replace
the gears if the gear backlash is
increased than the regular thirty% to
(three)Re-assemble the gears, maintain
the taper get in touch with spot is to 75%
(4)Change the bearing
two Collision
impeller and
wall, the
impeller best
and casing
(one) Installation gap is not correct
(2) operating force is as well
higher, exceeding the specified
(3) Functioning temperature is way too high
(four) Casing or base deformation,
positioning admirer failure
(five) Bearing axial area is not great
(1) Modify the gap
(two) Recognize brings about of
overloading, lowered the strain
to the specified price
(three) Examine the installation
accuracy and reduce the pipe
(four) Verify and mend bearings,
and to make certain the clearance
3 Temperature
way too high
(one) Oil in tank is as well much, too
thick or too soiled
(two) Filter or silencer is blocked
(3)The pressure is larger than
the specified benefit
(4)Abnormal put on of the
impeller, big hole
(5)Bad air flow, indoor
temperature is higher, ensuing in
inlet air’s high temperature
(6) The rotating pace is way too reduced,end result in the belt slipping.
(one)Reduce the oil stage or rely on
(2)Take away of blocking objects
(three)Reducing the force via
the blower
(4)Repair its clearance
(five)Open up vents to lessen room
(6) Increase pace to avoid the
belt slipping.
four Inadequate
(1) The inlet filter is blocked
(two) Impeller dress in and the hole
raises also significantly
(3) Belt slipping
(4) Huge imports stress loss
(5) Pipeline air flow leakage
(one) Clean the filter dust and
(two) Restore the hole
(3)Tighten the belt and increase
the variety of belts
(4)Change the inlet pressure to the
specified benefit
(5) Examine and repair the pipeline
five Oil leaking or
oil leaking
into the enclosure
(one)High tank placement cause
leakage from the discharge port
(two) Seal dress in, resulting in shaft oil spills
(3) The pressure is higher than
the specified price

(one)Reduce the oil level
(2)Change the seals
(3)Obvious the air vents, 2mm diameter faucet is mounted in the
middle chamber, open the faucet
under the wall
6 Abnormal
vibration and
(1)Bearing clearance exceeds the
specified worth or bearing put on
(2) The equipment backlash is too
huge, not in a tight fastened
(3) The international objects and dust
induced by the impeller and the
impeller, the impeller and the
housing collision
(4) the impeller shaft
deformation brought on the collision
induced by overload,
(five) Friction amongst the impeller

situation is damaged
(four)Examine the again strain, verify
the wheel and adjust hole
(five)Examine the filter and back
strain, increase the gap
amongst the impeller inlet and the
(6)Thoroughly clean the impeller and the
casing, to guarantee that the impeller
clearance work
(7) Tighten the anchor bolts and
leveling the foundation.
7 Motor
(1)Compared with the necessary
force, the pressure distinction
is huge that the back force or
the inlet strain is substantial
(two) When compared with the
products requirements, blower
flow is way too large, so its force
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (stuck)
rotating elements
(five) The oil stage is as well higher
(6) Slim V-belt is overheat,
vibration is also big, or pulley
is also tiny
(1) Decrease the stress to the
specified price
(2) Exhaust the excess fuel into
the atmosphere or lessen the
blower pace
(3) Eliminate the obstructions
(four)Instantly shut down, check out
the cause
(5) Change the oil to the correct
(six) Examine the belt tension, and
replaced it with massive diameter
