Compressor Oil for Piston-type and Rotary Compressors

compressor oil

Compressor oils are divided into classes depending on their application and requirements. The most common classifications is:

  • Oils for rotary and piston-type compressors;
  • Oils for refrigeration compressors;
  • Oils for turbo machines.

Let us consider in full detail the oil of the first type. It is used for lubrication of compressors in transportation and various industries. Requirements for the rotary and piston type compressor oils are defined by the composition and properties of the compressed gas which contacts the oil.

Apart from being used as a lubricant for the valves and cylinders of piston-type compressors, the oil is also used as a sealing medium for the compression chamber.

The main property of compressor oil is the thermal oxidation stability and the ability to prevent formation of coke deposits on the injection lines of compressors. The discharge temperature affects thermal oxidation stability.

Viscosity is also an important property of compressor oils. It determines the loss of energy through friction and wear of the surfaces of parts and seals of piston rings

Purity of compressor oils

Due to the fact that the application of compressor oils is similar to application of piston engine oils, the requirements for both oils are similar. Both are subjected to abrasion in a cylinder-piston group and in a crank mechanism.

The presence of water in compressor oil is determined by the Dean-Stark method, and is not allowed.

Cleaning of compressor oils

Contaminated with mechanical impurities and water, the compressor oil can not be used for its intended purpose.

The oil purification units by GlobeCore remove mechanical impurities, water and gas from compressor oils. Clean oil increases the performance of compressor equipment and reduces potential downtime. GlobeCore plants extend the life of both the oil and the compressor.
