What are the functions of vacuum oil?

This is to introduce the key functions of vacuum oil, which is essential for oil-sealed vacuum pumps, including rotary vane, rotary piston and rotary screw vacuum pumps.

As standard, the mineral oil is used as vacuum oil in the vacuum pumps for a long time. In recent years, more and more synthetic oil is introduced to improve the performance of vacuum pumps. People may not know all functions of vacuum oil besides lubricating. Following are the key functions:

Function 1: Lubrication

Lubrication is the basic function of the vacuum oil. The lubricating oil forms oil films between the pump cover, rotor, rotary vanes and pump body, avoiding direct contact with each other and reducing friction.

Function 2: Sealing

The oil film created by the vacuum oil plays an important sealing role for the vacuum pump. It improves the pump efficiency to achieve higher ultimate pressure.

Function 3: Cooling

The vacuum oil absorbs a large amount of compression heat and reduces the power of the vacuum pump during operation.

In addition, the vacuum oil reduces also the noise generated by high frequency compression of the vacuum pump.
