Automatic constant-pressure control device of air compressor

Abstract

The invention discloses an automatic constant-pressure control device of an air compressor. The automatic constant-pressure control device comprises a PLC (1), an air compressor I (2), an air compressor II (3), an air compressor III (4), an air compressor IV (5), an air compressor V (6) and an air compressor VI (7). The control end of the air compressor I (2), the control end of the air compressor II (3), the control end of the air compressor III (4), the control end of the air compressor IV (5), the control end of the air compressor V (6) and the control end of the air compressor VI (7) are all connected with a control port of the PLC (1).

Description

technical field [0001] The invention relates to an automatic constant pressure control device for an air compressor. Background technique [0002] Air compressor (hereinafter referred to as air compressor) is the production auxiliary equipment of the enterprise. After it is operated in a multi-unit network, due to the needs of production equipment, it is necessary to control the air pressure in the pipe network to a certain extent. If the number of air compressors is too large or the gas consumption of the gas equipment is small, the air pressure in the pipe network will increase, which will waste energy and cause the failure of the gas equipment. On the contrary, if the number of air compressors is small or the gas consumption of gas equipment is large, the air pressure in the pipe network will be low, which will affect the normal production of gas equipment. In the original control method, considering the dynamic changes in the gas consumption of production equipment and ...

AI Technical Summary

Problems solved by technology

If the number of air compressors is too large or the gas consumption of the gas equipment is small, the air pressure in the pipe network will increase, which will waste energy and cause the failure of the gas equipment

On the contrary, if the number of air compressors is small or the gas consumption of gas equipment is large, the air pressure in the pipe network will be low, which will affect the normal production of gas equipment

In the original control method, considering the dynamic changes in the gas consumption of production equipment and the influence of factors such as weather and temperature changes on the pipe network pressure during the day and night, it is often used to operate more air compressors to ensure that normal production of gas equipment, which results in waste of cost and energy
