Air compressor full-automatic control system and control method thereof

Abstract

The invention relates to an air compressor full-automatic control system and a control method thereof. The air compressor full-automatic control system comprises an engine, a relay, an air pump, an air storing tank, an unloading valve, a pressure adjusting valve, a pressure adjusting motor, sensors and a controller; one end of the engine is connected with a power source through the relay, the other end of the engine is connected with the air pump, the air pump is connected into the air inlet end of the air storing tank, the unloading valve is arranged on a connecting pipe of the air pump and the air inlet end of the air storing tank, the air outlet end of the air storing tank is externally connected with the pressure adjusting valve, the pressure adjusting valve is externally connected with the pressure adjusting motor, air outlets of the air storing tank and the pressure adjusting motor are connected with the sensor a and the sensor b through pipes, and the relay, the unloading valve,the pressure adjusting motor, the sensor a and the sensor b are electrically connected with the controller or are in signal connection with the controller. By means of the control system, engine opening and closing can be achieved, full-automatic adjustment of the air pressure of the air storing tank and pressure adjusting of the pressure adjusting valve can be achieved, the adjusting intelligentdegree is high, the automatic operation provides extra protection measures, and the problems about too high air pressure, engine starting difficulties and the like are solved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a fully automatic control system of an air compressor and a control method thereof. Background technique [0002] The air compressor is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually a motor) into gas pressure energy, and is a pressure generating device for compressing air. The basic components of an air compressor include a relay, an engine, an air pump, an air storage tank and a pressure regulating valve. The working principle is that the engine drives the air pump to press the gas into the gas storage tank, and the gas in the gas storage tank is output after being regulated by the pressure regulating valve. [0003] Most of the existing air compressors are manually controlled, that is, people need to manually open and close the relay to control the start and stop of the engine, so as to maintain the air p...
