This research takes the ⅤSV300 rotary vane pump as the research object. Figure 1 is its working principle diagram. The rotor is side eccentric, and three rotary vanes are installed in the rotor slot obliquely; the oil tank is side-hung on the pump cavity by 6 bolts, and the top is mounted There are oil mist filters and other components. In addition, the pump has a built-in automatic oil return prevention structure, oil filter and gas ballast device, and adopts air cooling. The three rotary vanes placed obliquely in the rotor slot divide the space enclosed by the outer surface of the rotor, the inner surface of the pump cavity and the end cover into three parts A, B, and C. When the rotor rotates in a clockwise direction, the rotary vanes are affected by centrifugal force and air Under the action of physical strength, the top of the pump cavity is always in contact with the inner wall of the pump cavity and slides along the inner wall of the pump cavity. The space B communicates with the air inlet, and the volume gradually increases and is in the process of inhalation; the volume of the space C communicating with the air outlet gradually decreases. , In the exhaust process; the volume of the space A between B and C gradually decreases, in the process of compression. As the volume of space B gradually increases and the gas pressure decreases, the external air pressure at the pump inlet is greater than the internal air pressure, and gas is sucked in. When space B is isolated from the suction port, the space B stops sucking, the volume gradually decreases, and the gas starts to compress. When the pressure of the compressed gas exceeds the exhaust pressure, the exhaust valve opens, and the gas passes through the internal oil to the exhaust port, and finally enters the atmosphere.
