  Application of air compressor for air compressor revamping

  Under the control of the compressor operation frequency state, the system is loaded with pressure control, and the motor is always in the state of power frequency. After the converter is transformed, the pressure of the pipe network can be controlled under any constant pressure, and the speed control of the motor is automatically controlled by the frequency conversion system.

  The pressure sensor device for detecting network, a frequency converter to analog signal through PID converter are given the appropriate regulation, voltage and frequency to adjust the speed of air compressor motor, and the output power of the motor, thus forming a closed loop feedback system to maintain the constant pressure of the pipe network, and can be adjusted automatically through the internal PLC.

  In practical applications, with the different time of day and night, the power needed is also different according to the amount of gas supply. The traditional way of regulation is loading through the adjustment of pressure valve.

  It is simpler to install the frequency converter. The motor from the original AC heavy demolition, fitted to the frequency counter, the cable leads from the air supply side to the frequency counter, external access control AC sampling signal, automatically adjust the motor speed to achieve constant pressure control (PID control), with the frequency (protection of overvoltage and overcurrent, overload, overheat and undervoltage protection).

  The advantages of frequency conversion are: the starting is convenient without impact current, automatic adjustment, constant pressure, low noise, less wear and less wear of machine parts, and smooth running of the machine.

  In short, through the transformation of the air compressor, it is not only easy to operate, simple and small maintenance, but also has significant energy saving effect, and realizes highly automatic adjustment, so as to achieve the requirement of high efficiency and energy saving.
