The working 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 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 fuel in the chamber is pushed to accomplish the
function of blowing.

Feature of our roots blower:
one. Huge adjustment of the air volume
2. Lower Noise
three. Higher effectiveness
4. Minimal vitality cosumption
5. Lengthy time life
six. Trustworthy working, simple servicing,little footprint

Our manufacturing unit is a expert producer of Roots blowers which has more than twenty years’ experience in equipment
producing. It is located in Xihu (West Lake) Dis. East Industrial Park, fifty kilometers to the east of Shan EPT provincial
funds— HangZhou. Our organization also has hassle-free visitors transportation, as it is 15 kilometers absent from
Diaozhen City station of HangZhou-HangZhou expressway, and 30 kilometers absent from East HangZhou station of
ZheJiang -ZheJiang expressway.The foremost solution of our firm is ESR -sort Roots Blower. The roots
vacuum pump is a new variety of large-effectiveness roots blower, which is designed independently primarily based on the
domestic and international sophisticated systems. Numerous patented technologies have been adopted on Roots
Blower, and hence we have made important effects in vitality conservation and noise reduction, and many others.. So significantly, our
company has invested more than 30,000,000 RMB to introduce these kinds of superior specialist equipment as
horizontal machining center, vertical machining heart, two-way CNC area planer, CNC lathe, CNC milling
machine, CNC planer, airplane grinder, cylindrical grinding machine, and three coordinates testing device.
In addition to, we have taken various steps to standardize the approach circulation this kind of as operating and cooperating
with several scientific research units, colleges and universities at property and abroad. We also repeatedly attempt to
take in and increase the domestic superior production systems, so as to encourage the upgrading and
optimization of the product and make the item good quality reach the sophisticated amount at house and abroad.
ESR -variety Roots Blower contains several collection this kind of as Three-leaves Kind, Two-leaves Sort and Centrifugal
Kind,which can be further divided to hundreds of varieties. The goods are widely employed in sewage therapy,
pneumatic conveying,vacuum packaging, aquaculture, foodstuff processing, EPT electrical power, petrochemical, cement,
mining and other industries. Our products have such rewards as minimal sound, strength conserving, steady top quality,
and long services daily life, and so on.. With the sales outlets throughout the domestic money metropolitan areas, our goods offer effectively all
more than the region, and have been exported to North America,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other international locations. Possessing acquired the ISO9001 Global High quality Program Certification, we have
set up and enhanced the good quality assurance of the merchandise designing, production, and installation.
From the method of style, research and improvement to the concluded products, we have acquired the whole
approach managed independently, as a result providing the entire foundation and trustworthiness ensure for the products balance
and toughness. Getting a perfect product sales network and following-product sales service, we provide our consumers with greater-
top quality and a lot more productive services.All personnel of our company sincerely welcome the wide masses of pals to

The Software of the Roots Blower

Maintenance and inspection
(one) Check all fasteners and finding pins circumstances whether they are loosening.
(two) Usually verify no matter whether the leakage phenomenon of the human body.
(3) Shell out interest to lubrication, quantity of grease and noises when working,
figure out whether or not it works beneath the necessary problems.
(4) Lubricant & grease: The lubricant is for medium load industrial equipment oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash level ≥ 200ºC)
The grease is butter (synthetic lithium grease penetration 220-250, fall level ≥
190ºC). Change the lubricant and grease after very first two hundred hrs operating, and change
once again soon after a moth running. Afterwards, exchange the lubricant and grease in accordance to the
setting and lubricant (grease) quality suggest a suited EPT for three
(five) Constantly check out the inlet air filter, clean or replace the filter in time.
(6) Blower overload occasionally not immediately displayed, so shell out attention to
the consumption and exhaust force, bearing temperature and the recent increase traits
of motor to figure out whether or not the blower functions normally
(seven) Ahead of disassembling the blower, the assembling relation and dimensions
must be recorded or measured, make marks on parts to make sure the authentic
specifications after assembling.
(eight) When recently device or overhaul, the oil tank should be cleaned prior to use
and propose replace all grease after eight hours working.

Frequent failure cause and troubleshooting

No Failure Feasible causes Elimination methods
one Friction

(one) Impurities on the impeller,
resulting in the gap is too small
(2) Gear put on, resulting in a
massive backlash
(3) The equipment is not nicely fastened,
can not keep the impeller
(4) Bearing dress in resulting in
clearance increasing.
(1) Get rid of dust and verify
whether there is hurt elements
(2) Change the gear hole, replace
the gears if the gear backlash is
better than the average 30% to
