The pump chamber of the dry screw vacuum pump is equipped with a pair of multi-stage spiral rotors that rotate synchronously in reverse meshing, dividing the pump chamber into several disconnected cavities. During normal operation, with the meshing rotation of the two rotors, a suction chamber is generated and the volume continuously increases to suck in gas. When the volume reaches its maximum, the suction chamber becomes an intermediate chamber; The middle chamber moves to the right to transport gas from the intake end to the exhaust end. When the middle chamber is connected to the exhaust port channel, the middle chamber becomes the exhaust chamber, and the volume of the exhaust chamber decreases to discharge gas. After all the gas is discharged, the next middle chamber begins to be connected to the exhaust channel. This cycle repeats itself to form a continuous pumping effect.
