We make all kinds of roots blower, centrifugal blower, Our Main products are as below:

The working 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. Through the action 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 gas in the chamber is pushed to achieve the
purpose of blowing.

Feature of our roots blower:
1. Large adjustment of the air volume
2. Low Noise
3. High efficiency
4. Low energy cosumption
5. Long time life
6. Reliable running, easy maintenance,small footprint

Our factory is a professional manufacturer of Roots blowers which has over 20 years’ experience in machinery
manufacturing. It is located in Xihu (West Lake) Dis. East Industrial Park, 50 kilometers to the east of Shan EPT provincial
capital— HangZhou. Our company also has convenient traffic transportation, as it is 15 kilometers away from
Diaozhen Town station of HangZhou-HangZhou expressway, and 30 kilometers away from East HangZhou station of
ZheJiang -ZheJiang expressway.The leading product of our company is ESR -type Roots Blower. The roots
vacuum pump is a new type of high-efficiency roots blower, which is developed independently based on the
domestic and foreign advanced technologies. Several patented technologies have been adopted on Roots
Blower, and thus we have made significant effects in energy conservation and noise reduction, etc.. So far, our
company has invested more than 30,000,000 RMB to introduce such advanced professional equipment as
horizontal machining center, vertical machining center, two-way CNC surface planer, CNC lathe, CNC milling
machine, CNC planer, plane grinder, cylindrical grinding machine, and three coordinates testing machine.
Besides, we have taken various measures to standardize the process flow such as working and cooperating
with many scientific research units, colleges and universities at home and abroad. We also continuously try to
absorb and improve the domestic advanced production technologies, so as to promote the upgrading and
optimization of the product and make the product quality reach the advanced level at home and abroad.
ESR -type Roots Blower includes several series such as Three-leaves Type, Two-leaves Type and Centrifugal
Type,which can be further divided to hundreds of varieties. The products are widely used in sewage treatment,
pneumatic conveying,vacuum packaging, aquaculture, food processing, EPT power, petrochemical, cement,
mining and other industries. Our products have such advantages as low noise, energy saving, stable quality,
and long service life, etc.. With the sales outlets throughout the domestic capital cities, our products sell well all
over the country, and have been exported to North America,Russia, Malaysia, Indonesia, Vietnam, South Africa
and some other countries. Having got the ISO9001 International Quality System Certification, we have
established and improved the quality assurance of the products designing, manufacturing, and installation.
From the process of design, research and development to the finished products, we have got the whole
process controlled independently, thus providing the full basis and reliability guarantee for the products stability
and durability. Having a perfect sales network and after-sales service, we provide our customers with higher-
quality and more efficient service.All staff of our company sincerely welcome the broad masses of friends to
guide, and negotiate business with us.

The Application of the Roots Blower

Maintenance and inspection
(1) Check all fasteners and locating pins conditions whether they are loosening.
(2) Always check whether the leakage phenomenon of the body.
(3) Pay attention to lubrication, amount of grease and noises when running,
determine whether it works under the required conditions.
(4) Lubricant & grease: The lubricant is for medium load industrial gear oil
(grade 220, kinematic viscosity of 198 ~ 242mm2 / s 40ºC, flash point ≥ 200ºC);
The grease is butter (synthetic lithium grease penetration 220-250, drop point ≥
190ºC). Replace the lubricant and grease after first 200 hours running, and replace
again after a moth running. Later, replace the lubricant and grease according to the
environment and lubricant (grease) quality; propose a suitable EPT for three
months.
(5) Always check the inlet air filter, clean or replace the filter in time.
(6) Blower overload sometimes not immediately displayed, so pay attention to
the intake and exhaust pressure, bearing temperature and the current increase trends
of motor to determine whether the blower works normally;
(7) Before disassembling the blower, the assembling relation and dimensions
must be recorded or measured, make marks on components to ensure the original
requirements after assembling.
(8) When newly machine or overhaul, the oil tank should be cleaned before use
and propose replace all grease after 8 hours running.
