Roots vacuum pump (referred to as: roots pump) refers to the pump is equipped with two opposite direction synchronous rotation of the leaf rotor, the rotor, the rotor and the pump shell wall has a small gap between the non-contact with a variable capacity vacuum pump.

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
