How dose a piston vacuum pump work?

The working principle of the rotary piston pump mainly depends on the effect of static pressure. When the power drives the transmission shaft to transmit torque, the driving shaft drives a pair of synchronous gears in the gearbox and the two rotors fixed on the pump shaft to make relative motion. In this process, the two working chambers of the pump will work in rotation, first connected to the suction port and disconnected from the discharge port to complete the suction stage; then disconnected from both the suction port and the discharge port to store liquid; finally connected to the discharge port and disconnected from the suction port to complete the discharge of liquid. Through the continuous rotation of the rotor, the pump can continuously inhale, store and discharge liquid.
