Variable-frequency control constant-pressure air compression system for printing and dyeing textile equipment

Abstract

The invention discloses a variable-frequency control constant-pressure air compression system for printing and dyeing textile equipment. The variable-frequency control constant-pressure air compression system for the printing and dyeing textile equipment comprises a motor, an air compressor, an air storage tank, a pressure transmitter, a PID regulator and a frequency converter. The motor is in power connection with the air compressor. The air compressor is connected with the air storage tank. The pressure transmitter is mounted on the air storage tank. The frequency converter is connected withthe motor of the air compressor in an electric control mode. The pressure transmitter is connected with the frequency converter through the PID regulator. According to the variable-frequency controlconstant-pressure air compression system for the printing and dyeing textile equipment, the pressure transmitter is mounted on the air storage tank and connected with the frequency converter through the PID regulator, the frequency converter is connected with the motor of the air compressor in the electric control mode, and the rotating speed of the motor of the air compressor can be automaticallycontrolled through the frequency converter so as to achieve constant air pressure control; the variable-frequency control constant-pressure air compression system has the advantages of low energy consumption and low power loss; and in addition, the motor of the air compressor can be softly started to reach a stable rotating speed from the static state, and the influence of large current and mechanical impact generated when the motor is started to the air compressor is avoided.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to an air compression system for textile printing and dyeing equipment. Background technique [0002] At present, the conventional air compression system used in textile printing and dyeing equipment such as setting machines, cloth rolling machines, etc., includes air compressors, air storage tanks, pressure reducing valves, air filters and other parts, which are generally operated by two parallel air compressors It is connected with the air storage tank to keep the air pressure constant. During this process, the motor of the air compressor is always running at full speed. The control of constant air pressure is generally achieved by loading or unloading the air compressor, and the operation of the air compressor The power is large, which leads to high energy consumption and serious power loss in the air pressure constant control of the air compression system. ...
