2X-4A rotary vane vacuum pump

The pump can be started directly from the atmosphere, it can be used alone, can also be used as a booster pump, roots pump, gas circulation cooling roots pump, oil diffusion pump, molecular pump before the pump, to maintain the pump, titanium pump pre pump. It can be used for vacuum coating, vacuum heat treatment, vacuum metallurgy, vacuum tube, bulb, chemical industry, packaging, plastic forming, photovoltaic, industrial and mining enterprises, such as distillation, drying, freezing, filtration, physical and chemical, etc..

一、 Characteristic

1, work requirements: import pressure greater than 6500Pa in the continuous working time, not more than 3 minutes to avoid fuel injection caused by loss of.

2, the work requirements: the inlet pressure is less than 1330Pa, allowing for a long period of continuous work.

3, ambient temperature: vacuum pump is generally at 5 degrees C -40 C room temperature and not higher than the relative temperature of 90% of the environment.

4, gas type: no other mixture at room temperature clean and dry air, do not contain other dust and moisture.

5, neon lamp manufacturing special vacuum pump, single crystal furnace, polycrystalline furnace, such as supporting the vacuum machine.

6, can be used as a separate vacuum pump, can also be combined with other high vacuum pump for the first pump.

7, a multi pump operation, improve efficiency, can save energy.
