ZJP Roots Vacuum Pump

Structure and characteristics: Roots vacuum pump refers to a mechanical vacuum pump with a pair of synchronized high-speed rotating octagonal rotors. There are clearances between rotors, rotors and systems, and rotors and side covers. There is no friction in the working chamber, and no lubrication is required. Therefore, it runs smoothly, has low noise, is reliable in use, and can operate for a long time under high pressure difference. This spring cannot be pumped separately and can only be used in series with a pre stage vacuum pump.

Performance characteristics:

1. There is a large pumping speed in a wide pressure range (1~1x10'pa).

2. The pump chamber is oil-free, avoiding oil vapor pollution of the vacuum system.

3. Low vibration and noise.

4. The mechanical friction loss is small, so the driving power is small,

5. Easy to maintain and repair, low cost, and long lifespan.

6. Can extract condensable gases. 7. Cannot be used alone, a pre pump must be configured. It is not allowed to start under human pressure. It can only be started when the front stage pump has pumped the Roots pump pressure to the allowable inlet pressure. The front stage pump is generally a water ring vacuum pump, oil ring vacuum pump, ten type vacuum pump, etc.
