CH-81-10-2 -- Design Basics - Screw Compressors

The paper describes the characteristics of the oil-injected screw compressor with emphasis on performance, reliability and applicability. The various functions of the oil in the compressor unit are discussed, especially the influence on the performance of different oil cooling methods.

This paper is intended mainly for those who design plants and use different kinds of compressors. It is important to know the characteristics of a compressor in order to be able to utilize its specific advantages properly in a given application. This paper describes the characteristics of the oilinjected screw compressor with special emphasis on performance, reliability arid applicability, all of which are important to the plant. designer. It describes the factors built into the compressor itself and the factors 4ssociated with its operating principles. Factors which can improve system performance and can be affected by the design of the system are also discussed. It is assumed that the reader is familiar with the basic operating principles of the screw compressor. They are described in a number of references.
