Compact, robust, reliable and economical. Widely used in basic vacuum equipment.
 
Working Principle
 
DPX rotary vane pump is mainly composed of the pump body, rotor, rotary vane, end cover, exhaust valve, etc. There is a cylindrical chamber in the pump body, the air inlet pipe and the exhaust valve are installed on the chamber, there is an eccentrically installed cylindrical rotor in the chamber, the top of the rotor is kept in contact with the cavity wall, there is a groove on the rotor, The rotary vane is placed, and there is a spring between the rotary vanes. When the rotor rotates, the top of the rotary vane always slides along the inner wall of the chamber with the help of the spring, and the oil film in between ensures the air tightness between the suction chamber and the exhaust chamber.
