Abstract
A compressor pressure measuring device drives a compressor to operate for measuring its pressure. A positive pressure pipeline and a negative pressure pipeline are connected to the entry end and the exit end of the compressor, respectively. The positive pressure pipeline and the negative pressure pipeline are provided with an electromagnetic valve, respectively. A control module controls the operation of the compressor and the on/off of the electromagnetic valves in the positive pressure pipeline and the negative pressure pipeline. This automatically detects positive pressure and negative pressure of the compressor.
