Patent ID: 8413487

Claim:
A compressor pressure measuring device for connecting to an entry end and an exit end of a compressor and driving a transmission axle of the compressor for a pressure test, the compressor pressure measuring device comprising: a platform having a holder for holding the compressor; a tool having an inner tooth hole for the insertion and connection of the transmission axle of the compressor, driven by a motor to drive the connected compressor into operation; a positive pressure pipeline, whose one end has a first connector corresponding to the exit end of the compressor and whose other end connects to a recycle bucket, having a first electromagnetic (EM) valve for controlling the connection state thereof, and having a positive pressure test area formed between the first connector and the first EM valve to accommodate a positive pressure gauge; a negative pressure pipeline, whose one end has a second connector corresponding to the entry end of the compressor and whose other end connects to a test fluid container, having a second EM valve for controlling whether the negative pressure pipeline is in fluid communication with the test fluid container or external air, and having a negative pressure test area formed between the second connector and the second EM valve to accommodate a negative pressure gauge; and a control module having a plurality of indicators electrically connected with the motor, the first EM valve, the second EM valve, and the positive and negative pressure gauges and controlling the on/off of the motor, the first EM valve, and the second EM valve for automatically testing the positive and negative pressures of the compressor; wherein the control module has default positive and negative pressure values, the control module compares the values measured by the positive and negative pressure gauges with the default positive and negative pressure values, and uses the indicators thereon to show the comparison result.
