Screw compressor is a common type of compressor, widely used in air compression, refrigeration, freezing and other fields. This article will introduce the working principle of screw compressor and its application.
First, the working principle of the screw compressor screw compressor is through the two intermeshing screw to realize the gas compression. One screw is called the active screw, and the other screw is called the driven screw. The active screw is driven by a motor to rotate, and the driven screw rotates with it. As the two screws rotate, the meshing space between them gradually decreases, thus causing the gas to be compressed.
The working process of a screw compressor can be divided into three stages: suction, compression and discharge. In the suction stage, the meshing space between the active screw and the driven screw gradually increases, and the gas enters the screw compressor through the air inlet. In the compression stage, the rotation of the two screws causes the gas to be gradually compressed, and the temperature is also increased. After the exhaust stage, the compressed gas is discharged from the screw compressor through the outlet.
Second, the application of screw compressor 1. air compression screw compressor in the field of air compression has a wide range of applications. It can compress a large amount of air into a higher pressure gas, which is used for power transmission in industrial production, pneumatic tools, pneumatic control systems and so on.
2. Refrigeration and freezing screw compressor is also widely used in the field of refrigeration and freezing. By compressing the refrigerant into a high temperature and high pressure gas, and then through the condenser to make it cool and condense into a liquid, and then through the expansion valve to make it expand into a low temperature and low pressure gas, so as to realize the purpose of refrigeration and freezing.
3. Industrial field screw compressor in the industrial field also has important applications. For example, in the petroleum, chemical, electric power and other industries, screw compressors are used in gas transportation, gas pressurization, gas circulation and other processes.
Screw compressor realizes gas compression through two screws meshing with each other, which has the advantages of simple structure, smooth operation and high efficiency. It has a wide range of applications in air compression, refrigeration, freezing and industrial fields. With the continuous progress of science and technology, the performance and efficiency of screw compressors will be further improved to provide better support for the development of various fields.
