In order to solve the problem that the operator needs to judge the starting resistance torque in the actual use, we added the automatic identification module to the control program, and the real-time pressure, motor starting current and starting time of the air compressor unit are real-time. The detection, according to the relationship between the pressure and the starting current, realizes the automatic control of the whole process of starting and stopping the compressor, and achieves good results. During the compressor blow-off control operation, the high-pressure air compressor needs to perform cyclic blow-off control on the emulsified liquid in the system air, and the control air pressure of the blower is (3~5) MPa. Due to the use of the LCD touch screen The man-machine interface, the control program will blow off the automatic control process and display it on the touch screen in the form of an intuitive progress indicator. The progress bar gives the operator a very intuitive view of the blowout situation. The blowing process parameters can be modified according to the progress indicator bar and the operating condition curve to achieve the best blowing effect.
Compressor working condition data record Real-time detection of working condition parameters during operation of high-pressure air compressor can timely reflect the condition of the compressor, which is an important means to ensure the correct operation of the operator and reduce the hidden troubles. In order to accurately and reliably collect physical data such as pressure, temperature, current, voltage, etc., a highly reliable (4-20) mA converter is used as a live signal sensor. The control program uses the dynamic data refresh technology to realize the real-time display and recording function of the running parameters. It can record the main operating parameters periodically and display them on the touch screen in the form of a table. When the memory capacity overflows, the system will automatically refresh the 25% data area that was first stored and continue to record the operating parameters.
