Characteristics of vacuum pump

Release time：

2021-09-15

(1) There is a large pumping speed in a wide pressure range; (2) The rotor has good geometric symmetry, so it has small vibration and stable operation. There is clearance between rotors and between rotors and shells, no lubrication, small friction loss, which can greatly reduce the driving power, thus achieving higher speed;

(2) The rotor has good geometric symmetry, so it has small vibration and stable operation. There is clearance between rotors and between rotors and shells, no lubrication, small friction loss, which can greatly reduce the driving power, thus achieving higher speed;

(3) The pump chamber does not need oil sealing and lubrication, which can reduce the pollution of oil vapor to the vacuum system;

(4) There is no compression or exhaust valve in the pump chamber. Simple and compact structure, insensitive to dust and water vapor in the extracted gas;

(5) The compression ratio is low, and the effect of hydrogen extraction is poor;

(6) The rotor surface is a curved cylinder with complex shape, which is difficult to process and inspect.
