How to select the vacuum pump type _

is a rotary vacuum pump variable volume vacuum pump. Must be equipped with backing pump. It can be used in a wide pressure range. Pumping speed is not sensitive to extract the dust in the gas and water vapor. It is widely used in metallurgy and chemical industry. Food, electronic paint and other industries.

vacuum pump working principle:

1, you should fully understand the pumping gas composition. For example, gas excluding condensable vapor, dust particles, corrosion or explosive. If the steam is contained in the gas, particles and corrosive gas, please consider condenser installed in the pump inlet pipe, dust collector and other auxiliary equipment. If gas is corrosive, it must be made of stainless steel. If gas extraction is explosive, should choose water ring vacuum pump is equipped with explosion-proof motor, because the water ring vacuum pump in the whole operation process is isothermal.

2。 Requirements of oil pollution of vacuum equipment or components. If equipment strict with oil free, should choose a variety of oil pump, such as: water ring vacuum pumps, molecular sieve adsorption pump, sputter ion pump, cryogenic pump, etc. If not strict, you can choose to have an oil pump, and add some oil measures, such as add cold trap, baffle, the oil well, etc. , can also meet the requirements of clean vacuum.

3。 Vacuum pump oil vapor how to affect the environment? If you don't allow pollution environment, you can choose oil-free vacuum pump, water ring vacuum pump or the oil vapor emission outside.

4。 If there are multiple large water ring vacuum pump work at the same time, the circulation fluid should be cooling, otherwise it will affect the vacuum. Cooling device can be equipped with cooling tower, must use the booster water pump to the pipeline pressure.

5。 Vacuum pump working pressure should satisfy the limit of vacuum equipment vacuum and work pressure requirements. Usually choose vacuum degree of vacuum pump is higher than vacuum degree of vacuum equipment to half an order of magnitude.

6。 Vacuum pump should be able to work under pressure to remove all gas produced in the process of vacuum equipment.

7。 Vacuum pump vibration of the work has no effect on the process and the environment. If the environment does not allow, please select no pump vibration or shock absorption measures.
