Rotary Vane Vacuum Pump and Liquid Ring Vacuum Pump are two common types of vacuum pumps. They have some differences in terms of working principle, application fields, advantages and disadvantages, etc.
A vacuum pump refers to a device or device that uses mechanical, physical, chemical or physicochemical methods to evacuate the evacuated container to obtain a vacuum. Generally speaking, a vacuum pump is a device that uses various methods to improve, generate and maintain vacuum in a certain closed space.
The rotary vane vacuum pump is an oil-sealed mechanical pump that achieves gas extraction by utilizing a rotor to drive vanes in an eccentric rotation, thereby altering the volume of the pump chamber. It is widely employed as a backing pump and for providing low-vacuum environments in scientific research and industrial settings.
