Embodiment Construction

[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] The air compressor control system of the present invention is as figure 1 As shown, it includes frequency converter, pressure sensor, motor and corresponding control circuit. The pressure sensor is used to measure the air pressure value of the air storage tank. The pressure sensor is connected to the frequency converter, and the output terminal of the frequency converter is connected to the motor. Here The pressure sensor adopts a potentiometer pressure gauge, and the output terminal of the pressure gauge is connected with the speed adjustment control terminal of the frequency converter. Such as figure 2 As shown, the inverter takes the pressure of the air storage tank in the air compressor as the control object, and the pressure sensor is installed on the outlet of the air storage tank to convert the pressure of the air storage tan...

Abstract

The invention relates to a control system of an air compressor, which belongs to the technical field of air compressor control. According to the control system of the air compressor, disclosed by the invention, the output pressure of compressed air of the air compressor is used as a control object, the regulation of motor speed by air demand is realized by using a variable frequency speed regulating mode, the pressure at an air outlet can rise when the air consumption is reduced, the pressure can be fed back to a frequency converter through a pressure sensor, the motor speed can be slowed down, and the shaft output power can be reduced; the pressure of the air outlet drops when the air consumption is increased, the motor speed is quickened, and the shaft output power is increased; and therefore the air compressor control system disclosed by the invention has the advantages that the pressure control accuracy can be controlled, the energy source is saved, the running cost is reduced, the noise of the air compressor is reduced at the same time, and the service life of the air compressor is prolonged.

Description

technical field [0001] The invention relates to an air compressor control system, which belongs to the technical field of air compressor control. Background technique [0002] The general air compressor is a piston compressor, which is driven by an asynchronous motor to drive the pulley to directly drive the crankshaft through the coupling, so that the piston reciprocates in the compressor cylinder to complete the process of suction, compression, discharge, etc. The gas is pressurized and output to the storage tank. Among them, the piston assembly, the piston, the inner wall of the cylinder and the cylinder head form a working chamber with variable volume, driven by the crank connecting rod, it reciprocates in the cylinder to realize the gas in the cylinder. Since the air compressor cannot rule out the possibility of running for a long time under full load, the capacity of the motor can only be determined according to the maximum demand, and the design margin is generally t...
