  • Patent number: 8413487
    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.

  • Patent number: 8347690
    Abstract: A compressor leakage detector includes a water tank, an elevator platform, a control panel, and a pressure testing unit. The elevator platform is disposed in the water tank to rise and drop vertically. The operating panel of the control panel has a human-machine interface, indicators, and pressure gauges. The pressure testing unit in the control panel uses an intake pipe to connect to several branch pipes that in turn connect to the compressors in the water tank. Each of the branch pipes connects in series to at least one intake EM valve and at least one exhaust EM valve. A pressure sensor is interposed between the intake EM valve and the corresponding compressor.

  • Publication number: 20120167925
    Abstract: A compressor cleaner includes a machine body with a tunnel, a transporting unit connected with several conveyors, a driving unit for driving the compressors on the conveyors to rotate dining the cycle. The conveyors are driven by the transporting unit to enter an entry side and to carry compressors. They first enter the cleaning room for cleaning, then the front drying room and the rear drying room for drying. The dried compressor then goes to the exit side.
