 Scope of use

ZJ series Roots vacuum pump is a kind of rotary variable volume vacuum pump. It can be used only with the cooperation of the front pump. It has a large pumping speed in a wide pressure range and is insensitive to dust and steam in the extracted gas. It is widely used in metallurgical, chemical, paper-making, food and electronic industries.
main features
1. There is a larger pumping speed in a wide pressure range.
2. The rotor has good geometric symmetry, so it has small vibration and smooth operation. There are clearances between the rotors and between the rotors and the housing. Without lubrication, the friction loss is small, and the driving power can be greatly reduced.
3. There is no need for oil seal and lubrication in the pump chamber, which can reduce the pollution of oil vapor to the vacuum system.
4. There is no compression and exhaust valve in the pump chamber. Its structure is simple and compact, and it is insensitive to dust and water vapor in the exhausted gas.
5. Compression ratio is low and the effect of hydrogen extraction is poor.
6. Start up quickly and work immediately.
