What is the pressure of the general air compressor

The pressure of the general air compressor varies according to the use requirements and the environment. For the pressure range of ordinary air compressors, the rated working pressure can usually reach 0.7-0.8Mpa, but in actual use, the discharge pressure of most compressors is about 0.6Mpa. Some special high-pressure air compressors, such as high-pressure air compressors, exhaust pressure can reach up to 5.0Mpa. However, the discharge pressure indicated on the compressor nameplate is the rated working pressure of the compressor, that is, the highest pressure that allows the compressor to run continuously. When the actual discharge pressure of the compressor is higher than this value, it should be forced to unload, otherwise the safety valve will automatically discharge.

In addition, for screw air compressors, the exhaust pressure during normal operation is 0.7-0.8Mpa, while some high-pressure screw air compressors can reach a working pressure of about 1.0Mpa, and even some screw machine exhaust pressure can reach 1.4-1.6Mpa. However, long-term high-pressure operation will accelerate the wear of the screw and bearing, which has a great impact on the life of the machine.

When choosing an air compressor, the appropriate pressure range should be determined according to actual needs, and the machine should be prevented from running under high pressure for a long time to extend the service life of the equipment. At the same time, in order to maintain the normal operation of the air compressor, regular maintenance and maintenance are required, including replacing the filter, checking the oil level, and cleaning the radiator.

In general, the pressure of the air compressor depends on its type and use environment. In general industrial applications, the pressure range of the air compressor is between 0.6-1.6Mpa.
