Air compressor dormancy control method

Abstract

The invention discloses an air compressor sleep control method. The air compressor sleep control method comprises the following steps: a controller records an air consumption corresponding to a frequency under the condition of stable operation of a machine; the controller monitors a real-time displacement of an air compressor in real time, in particular a displacement of the air compressor before sleep; the controller records and monitors the sleep time of the air compressor; if the sleep time is long, during waking, the controller judges according to the record, and reduces the upper limit frequency of operation of the whole air compressor to a reasonable value to guarantee voltage stabilization in waking start without influencing use of users; and the air compressor enters PID adjustment according to the air consumption. The air compressor sleep control method uses matching between the displacement of the air compressor and the PID adjustment for realizing sleep control of the air compressor, reduces the sleep and waking frequency of the air compressor, reduces the damage of the air compressor, and prolongs the service life of the air compressor.

Description

technical field [0001] The present invention relates to air compressor control technology, in particular to the technical field of air compressor control. Specifically, it shows an air compressor dormancy control method. Background technique [0002] Air compressor refers to a device that converts electric energy into air kinetic energy. The use of air compressor involves all walks of life. Through the PID adjustment of the driver, it can bring the required constant pressure gas to the end user. With the continuous improvement of the level of mechanization Improvement, various industries have higher and higher requirements for the manufacturing quality and technical level of the air compressor; [0003] At present, the air compressor industry at home and abroad is going through a process of electrical control frequency conversion. This process is actually a process of improving the efficiency of the whole machine and saving energy. Compared with the power frequency machine, ...

Problems solved by technology

[0004] At this stage, only PID control is done for pressure to ensure constant pressure output, and enter sleep when the air volume is small; but the length of sleep is not considered, and the sleep time of air compressor is relatively short (even frequent sleep and wake-up). There is a large damage to the whole machine system
