Dry screw vacuum pump selection method _ at 9 o 'clock

how to choose dry screw vacuum pump? Many people have no idea, you will find factory engineer, others will be according to the previous old pump nameplate to vacuum pump manufacturers, this is a fast and accurate. Our own how to choose the pump type.

dry screw vacuum pump selection

1, the dry screw vacuum pump work the effects of vibration on the technological process. If cannot vibration process requirement, to be considered and shockproof measures.

2, understand the screw vacuum pump will pump gas, smoke to whether the gas containing condensable gases, containing water vapor, dust particles or does not exist, or no corrosive. When the choice, want to know the gas composition, selection of dry screw vacuum pump for gas. If gas contains water vapor, particles and corrosive gas, should consider the pipe on the installation of auxiliary equipment, such as condensers, heat exchangers, dust collector, etc.

3, under the operating pressure, should be able to come in the process of the gas volume.

4, the right combination of dry screw vacuum pump. Because of the selective extraction pump, therefore, you can select a pumped gas can not meet the requirements, it requires multiple pump vacuum unit to meet the swept volume.

5, vacuum pump with pollution. If there is no strict with oil-free vacuum pump, should choose to various kinds of oil pump.

6, right choice dry screw vacuum pump working point. Within the scope of each pump has a certain work pressure, pump working point should choose more appropriate in this scope, but can't let it in the long run of 25? 30 MMHG.

7, the discharge of oil vapor's impact on the environment. If the environment does not allow pollution can choose no oil or oil vapor discharge outside.

8, working pressure should satisfy screw limiting vacuum of vacuum pump and the requirement of stress at work.

9, dry screw vacuum pump prices. The freight and later maintenance, etc.
