Introduction to Rotary Screw Air Compressor

Clicks: 27
Rotary screw air compressors, also known as screw compressors, are classified into single screw compressors and twin screw compressors. The single-screw compressor was developed by Sinen of France in the 1970s. Because of its more reasonable structure and rapid application to the national defense field, it has been protected by the developing country, and the technology has been relatively independent. The twin-screw compressor was first proposed by the Germans in 1878. It was not until 1934 that A.Lysholm of the Royal Institute of Technology in Sweden laid the screw-type compressor SRM technology and began to apply it in industry and achieved rapid development.

In the 1950s, oil-injected screw compressors were already used in refrigeration equipment. Due to their simple structure and less wearing parts, the exhaust gas temperature was low under high pressure or pressure ratio conditions. The agent containing a large amount of lubricating oil (often referred to as wet stroke), which is insensitive, has good gas volume regulation and quickly occupies the use range of large-capacity reciprocating compressors It continuously extends to the medium capacity range. It is used in refrigeration equipment such as refrigeration, refrigeration, air conditioning and chemical processes. The screw heat pump based on it has been used for heating and air conditioning since the early 1970s and has air heat source type, water heat pump type, heat recovery type, ice storage type and the like. In the industrial sector, screw-type heat pumps are also used for heat recovery in order to save energy.
