Application of roots vacuum pump :

Roots vacuum pump, widely used in petroleum, chemical, plastics, pesticides, steam turbine rotor balancing, aerospace space simulation devices such as petroleum, chemical, metallurgy, textile and other industries.The accessories for the vacuum pump is vavuum pump muffler , which can deal with the noise.

Structural features of roots vacuum pump:

(1)within a wide range of pressure has a larger pumping speed;
(2) the rotor has good geometric symmetry, so the vibration is small, smooth operation.There are gaps between the rotor and the rotor and the shell, it needs no lubrication, friction loss is small, can greatly reduce the drive power, which can achieve a higher turn
Speed;
(3) the pump cavity without oil seal and lubrication, it can reduce the oil vapor, which will pollut the vacuum system;
(4) pump cavity without compression, no exhaust valve. The structure is simple, compact,

Characteristics of roots vacuum pump

1.Start fast,
2.Less power consumption,
3.Low operation and maintenance costs,
4.Pumping speed, high efficiency

Product Description
Roots vacuum pump is a dry positive displacement pump. They operate on the Roots principle, which is similar to that of rotary vane pumps. These pumps are the ideal solution when fast pumping speeds are required. In the case of contactless, oil-free compression Roots booster pumps, two symmetrical cams rotate in the working chamber. During this process, the rotating blades do not come into contact with each other or the housing. Roots vacuum pumps are often used in pumping stations in combination with oil-lubricated rotary vane pumps to achieve very high volume flows and deep final vacuums.

Benyuan's three-lobes roots vacuum pump is an internationally advanced roots blower produced by importing and digesting patents and proprietary technology from the American Hibar company and utilizing the company's advanced manufacturing processes.

Features
