A single-stage oil-sealed rotary vane vacuum pump is a type of vacuum pump that utilizes rotating vanes and oil as a sealing and lubrication medium. It is commonly used in various industrial, scientific, and research applications where a moderate level of vacuum is required.
The operating principle of a single-stage oil-sealed rotary vane vacuum pump involves a cylindrical rotor with multiple vanes that are eccentrically mounted. As the rotor rotates, the vanes slide in and out of their slots, creating variable-volume pumping chambers. As the chambers expand, air or gas is drawn in through the inlet. As the chambers decrease in volume, the air or gas is compressed and expelled through the outlet.
