Vacuum pump is a kind of revolving variable capacity. It needs the cooperation of the front pump to use in a wide pressure range with a larger pumping speed. It is insensitive to dust and steam contained in the extracted gas. It is widely used in metallurgy, chemical industry, food, electronic coating and other industries.
Characteristic:
(1) There is a large pumping speed in a wide pressure range.
(2) The rotor has good geometric symmetry, so it has sm...
