1. vacuum pump is the basic equipment used to remove the gas from the sealed container and obtain the vacuum. It can be used alone or as a pre pump and pre pump for all types of vacuum systems. It is widely used in medical, scientific research, chemical, laboratory, plastics, electronics and other industries, as well as in the manufacture of electric vacuum devices, bulbs, thermos bottles, vacuum welding, instruments and refrigeration equipment, printing and packaging machinery, etc.

2. vacuum pump working environment: temperature 5`C90%A inch, should open the gas valve. 90% of the intake pressure is less than 10 torches, allowing long-term continuous operation. When the relative humidity of the exhausted gas is more than 90%, the air ballast valve should be opened.

3. vacuum pump inlet continuous open atmosphere operation, not more than three minutes.rotary-vane-vacuum-pump-limit-pressure
