The operating basic principle of the three-blade roots blower: two three-lobed rotors are arranged in the cavity, and the
suction port and the discharge port are opened on both sides of the cavity. By means of the action 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 gasoline in the chamber is pushed to achieve the
purpose of blowing.

Function of our roots blower:
1. Huge adjustment of the air volume
2. Minimal Noise
three. Large performance
4. Reduced power cosumption
5. Extended time existence
6. Reliable running, simple routine maintenance,little footprint

Our manufacturing unit is a professional producer of Roots blowers which has over 20 years’ experience in equipment
manufacturing. It is found in Xihu (West Lake) Dis. East Industrial Park, 50 kilometers to the east of Shan EPT provincial
cash— HangZhou. Our organization also has handy traffic transportation, as it is fifteen kilometers absent from
Diaozhen Town station of HangZhou-HangZhou expressway, and thirty kilometers away from East HangZhou station of
ZheJiang -ZheJiang expressway.The foremost merchandise of our company is ESR -kind Roots Blower. The roots
vacuum pump is a new type of higher-effectiveness roots blower, which is developed independently dependent on the
domestic and overseas innovative technologies. Several patented technologies have been adopted on Roots
Blower, and hence we have created considerable outcomes in power conservation and noise reduction, etc.. So significantly, our
organization has invested a lot more than 30,000,000 RMB to introduce such innovative skilled tools as
horizontal machining centre, vertical machining middle, two-way CNC floor planer, CNC lathe, CNC milling
machine, CNC planer, airplane grinder, cylindrical grinding machine, and three coordinates testing machine.
Apart from, we have taken a variety of actions to standardize the approach flow this kind of as working and cooperating
with several scientific research units, faculties and universities at house and abroad. We also continuously try out to
soak up and increase the domestic sophisticated creation technologies, so as to market the upgrading and
optimization of the merchandise and make the item good quality get to the superior degree at home and overseas.
ESR -sort Roots Blower consists of a number of sequence this sort of as 3-leaves Variety, Two-leaves Sort and Centrifugal
Variety,which can be further divided to hundreds of varieties. The items are extensively utilized in sewage treatment,
pneumatic conveying,vacuum packaging, aquaculture, meals processing, EPT electrical power, petrochemical, cement,
mining and other industries. Our products have this sort of benefits as reduced sound, strength preserving, steady top quality,
and lengthy services life, and so forth.. With the revenue outlets throughout the domestic funds metropolitan areas, our products promote properly all
over the region, and have been exported to North The united states,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other international locations. Getting obtained the ISO9001 Intercontinental High quality Program Certification, we have

The Application of the Roots Blower

Servicing and inspection
(one) Check all fasteners and finding pins problems no matter whether they are loosening.
(2) Usually check regardless of whether the leakage phenomenon of the entire body.
(3) Spend attention to lubrication, quantity of grease and noises when running,
decide whether or not it works under the essential problems.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(quality 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash position ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, drop level ≥
190ºC). Substitute the lubricant and grease right after very first 200 hrs operating, and change
again following a moth working. Later on, replace the lubricant and grease according to the
environment and lubricant (grease) high quality suggest a suited EPT for a few
(five) Often verify the inlet air filter, clear or exchange the filter in time.
(6) Blower overload at times not quickly exhibited, so shell out interest to
the consumption and exhaust stress, bearing temperature and the present boost trends
of motor to decide no matter whether the blower functions usually
(seven) Before disassembling the blower, the assembling relation and dimensions
have to be recorded or measured, make marks on parts to make sure the unique
needs right after assembling.
(8) When recently machine or overhaul, the oil tank must be cleaned ahead of use
and suggest substitute all grease right after eight hours working.

Common failure explanation and troubleshooting

No Failure Possible causes Elimination strategies
1 Friction
among the
(one) Impurities on the impeller,
ensuing in the hole is as well little
(2) Gear put on, resulting in a
huge backlash
(three) The equipment is not properly fixed,
can not preserve the impeller
(four) Bearing use resulting in
clearance rising.
(one) Remove dirt and examine
whether or not there is injury areas
(2) Adjust the gear gap, substitute
the gears if the equipment backlash is
increased than the average 30% to
(three)Re-assemble the gears, preserve
the taper speak to location is to seventy five%
(four)Change the bearing
2 Collision
impeller and
wall, the
impeller top
and casing
(one) Set up gap is not proper
(2) functioning strain is way too
large, exceeding the specified
(three) Running temperature is way too large
(four) Casing or base deformation,
positioning enthusiast failure
(five) Bearing axial location is not very good
(1) Modify the gap
(2) Discover leads to of
overloading, lowered the strain
to the specified benefit
(three) Check out the set up
precision and minimize the pipe
(4) Check and mend bearings,
and to guarantee the clearance
3 Temperature
as well substantial
(one) Oil in tank is also considerably, way too
thick or too soiled
(2) Filter or silencer is blocked
(3)The stress is larger than
the specified value
(four)Excessive dress in of the
impeller, huge hole
(five)Inadequate air flow, indoor
temperature is substantial, resulting in
inlet air’s substantial temperature
(6) The rotating pace is as well reduced,end result in the belt slipping.
(one)Minimize the oil degree or rely on
(two)Take away of blocking objects
(3)Minimizing the stress via
the blower
(four)Restore its clearance
(five)Open up vents to minimize place
(six) Enhance pace to stop the
belt slipping.
four Inadequate
(1) The inlet filter is blocked

5 Oil leaking or
oil leaking
into the enclosure
(1)High tank situation trigger
leakage from the discharge port
(2) Seal put on, resulting in shaft oil spills
(3) The strain is increased than
the specified worth

(one)Minimize the oil stage
(two)Change the seals
(three)Very clear the air vents, 2mm diameter faucet is fixed in the
center chamber, open the faucet
below the wall
six Irregular
vibration and
(one)Bearing clearance exceeds the
specified price or bearing dress in
(two) The equipment backlash is too
huge, not in a limited set

case is broken
(4)Check the back force, verify
the wheel and modify hole
(five)Check out the filter and back again
pressure, enhance the gap
amongst the impeller inlet and the
(6)Clean the impeller and the
casing, to guarantee that the impeller
clearance perform
(7) Tighten the anchor bolts and
leveling the base.
seven Motor
(one)When compared with the required
stress, the stress big difference
is large that the back force or
the inlet strain is substantial
(two) In contrast with the
tools requirements, blower
circulation is way too huge, so its strain
(3)Inlet filter is blocked, or outlet
pipe is obstructed or blocked
(4) Collusion or friction (caught)
rotating areas
(five) The oil degree is also high
(six) Narrow V-belt is overheat,
vibration is way too large, or pulley
is also little
(one) Decrease the strain to the
specified benefit
(two) Exhaust the excess gas into
the atmosphere or minimize the
blower pace
(three) Take away the obstructions
(4)Right away shut down, check out
the cause
(5) Adjust the oil to the right
(6) Check the belt stress, and
replaced it with big diameter
