Does air compressor belong to special equipment

Air compressor is not special equipment. However, as long as the working pressure of the gas storage tank and the connected pipeline is greater than or equal to 0.1Mpa, the volume and the pipe diameter are greater than or equal to 25mm, it belongs to special equipment.

Special equipment refers to boilers, pressure vessels, pressure pipes, elevators, lifting appliances, passenger ropeways, large amusement facilities and special motor vehicles in the field (factory) that involve life safety and high risk. Among them, boilers, pressure vessels (including gas cylinders) and pressure pipes are special pressure-bearing equipment; elevators, hoisting machinery, passenger ropeways and large amusement facilities are electromechanical special equipment.

the role of air compressor:

1. Air compressors for gas transportation are also used for gas pipeline transportation and bottling, such as remote gas and natural gas transportation, chlorine and carbon dioxide bottling, etc.

2. Used for gas synthesis and polymerization. In the chemical industry, some gases are synthesized and polymerized after the pressure is increased by the compressor, such as helium synthesis from hydrogen and hydrogen, methanol synthesis from hydrogen and carbon dioxide, urea synthesis from carbon dioxide and ammonia, etc., and polyethylene production under high pressure.

3. The gas used for refrigeration and gas separation is compressed, cooled, expanded and liquefied by an air compressor. It is used for artificial refrigeration. This type of compressor is usually called an ice maker or an ice machine. If the liquefied gas is a mixed gas, each group can be separated separately in the separation device to obtain various gases with qualified purity, such as the separation of petroleum cracking gas. First, it is compressed, and then each component is separated separately at different temperatures.

4, can be used as aerodynamic air after compression can be used as power, mechanical and pneumatic tools, as well as control instruments and automation devices, instrument control and automation devices, such as machining center tool replacement.
