Lubrication guidelines for rotary vane compressors

Third Quarter 2008 Other technologies

Arthur Rushmer Engineering has compiled a 17-page document on this subject and has given Motion Control permission to host the guide on its website so that readers can access it in its entirety.

The following serves as an introduction:

Function of the lubricant

The oil in a rotary vane compressor serves four main purposes:

* Lubrication.

* Sealing.

* Cooling.

* Protection.

There are many undesirable and desirable characteristics for lubricants:

They should not:

* Form deposits.

* Age quickly.

Ideal lubricant properties include:

* Lowest possible viscosity.

* Highest lubricating power.

* Resistance to high temperatures.

* Detergent and dispersant properties.

* Chemical stability.

* Technical-economic benefits (ideal properties vs. cost).

Lubricant analysis

Regular analysis of the lubricant in a compressor provides an important insight into:

* Suitability of lubricant for continued use.

* Quality of intake air.

* State of wear of compressor.
