Selection of dry vacuum pump

The specifications and models of dry vacuum pump are various, and the manufacturers are different, and there are certain differences in the number of products. As a customer, what should we pay attention to in the whole process?

1. Whether the vibration produced during the operation of dry vacuum pump affects the process and environment. If all production processes are not allowed, choose vibration free pump or take vibration isolation measures.

2. Master the components of the steam absorber. The steam body does not contain condensate gas, water vapor, particle dust and corrosion. In the selection process, it is necessary to establish the knowledge of steam body parts and select the relative dry vacuum pump. If the steam, particulate matter and the steam body in the steam body are corroded, the mechanical equipment such as cooler, heat exchanger and dust removal equipment on the inlet pipe of the pump shall be replaced.

3. Under pressure, all steam volume caused in the whole process of vacuum technology processing shall also be discharged.

4. Make up mechanical pump properly. Because the pump has optional vacuumizing, sometimes it is not allowed to consider the vacuumizing regulations when using a pump. Several types of pumps must be combined to fill each other before the vacuumizing regulations can be considered.

5. Regulations of vacuum technology on oil environmental pollution. If there is no oil stain in the strict management of machinery and equipment, all kinds of gasoline free pumps should be selected.

6. Properly select the working position of dry vacuum pump. Each pump often has a certain range of working gas pressure, and the working position of the pump should be set in this range, which is more suitable, rather than allowing it to work for a long time under 25 ~ 30mmhg.

7. How does the discharged oil vapor harm the natural environment. If the natural environment does not allow environmental pollution, you can choose the one without oil stain or exhaust the oil vapor outdoors.

8. The limit vacuum pump of vacuum technology and the regulation of gas pressure in operation should be considered.

9. Price, transportation cost and maintenance cost of the dry vacuum pump.
