Vacuum pump for extrusion manufacturers tell you that a vacuum pump refers to a device or equipment that uses mechanical, physical, chemical or physical-chemical methods to pump the container to be vacuumed.
The vacuum pump for extrusion manufacturer tells you that the two rotors of the vacuum pump are operated relatively synchronously through a pair of high-precision gears. The driving shaft is connected with the motor through a coupling.
The working principle of the vacuum pump for extrusion is the same as that of the general positive displacement vacuum pump. A rotor is eccentrically installed in the inner cavity of the vacuum pump. There are three radially sliding rotary vanes on the rotor.
