Its working principle is the same as that of a general positive displacement pump, and it is composed of stator, rotor, rotary vane, cylinder, motor and other main parts.
The rotor with the rotary vane is installed eccentrically in the fixed cylinder. When the rotor rotates at high speed, the four radial sliding rotary vanes in the rotor slot divide the pump cavity into four working rooms. Due to the centrifugal force, the rotary vane is tightly attached to the The wall of the cylinder separates the inlet and outlet of the stator, and rotates again and again to change the volume and discharge the inhaled gas from the exhaust port to achieve the purpose of pumping.
