rotary vane vacuum pump scope of application

The rotary plate-type vacuum pump is a bipolar structure, which consists of a high pressure level and a low pressure level. The suction inlet connects with a vacuum container or a vacuum device, and the gas in the container is inhaled and discharged during the operation. When rotary vane vacuum pump in the vacuum, high pressure stage exhaust valve will shut down, suction gas will be transferred to the second, and the secondary suction and discharge, such vacuum equipment must be vacuum can be obtained.

Rotary vane vacuum pump is to point to inside the pump eccentric rotor and stator fixed plane of tangent, two rotary vane in the rotor sliding groove, and the stator inner surface contact, the pump cavity is divided into multiple variable displacement of a revolving variable volume pump.

Rotary vane vacuum pumps can according to user’s application situation, equipped with the vacuum pump, the pump as a backing pump, as a result of the booster pump pumping power to strengthen, the former of ejector pump; can obtain higher vacuum, be applicable to the metallurgical, chemical, electric light source vacuum, vacuum coating, food packaging, medicine, blister, electronics other industries.

The vacuum pump has a wide range of applications, mainly for the following situations:

1. Air type: clean and dry air without other mixtures at room temperature. No air containing other dust and water is allowed.

2. When the inlet pressure is greater than 6500Pa, the continuous working time shall not exceed 3 minutes to avoid pump damage caused by oil injection.

3. When the inlet pressure is less than 1330pa, the vacuum pump is allowed to work continuously for a long time.

4. environment temperature, the use of vacuum pump temperature in not less than 5 ℃ at room temperature, and environment relative humidity is not higher than 90%.
