Abstract: In order to scientifically grasp the operation of water ring vacuum pumps and accurately evaluate the operation state of
water ring vacuum pumps, this paper introduced the detection methods of performance parameters of water ring vacuum pumps in
coal mine, such as gas volume, suction pressure, discharge pressure, rotating speed, shaft power and isothermal compression
efficiency, water supply volume and pressure, temperature, ambient air pressure and relative humidity, vibration and noise, converted
the test data to the specified conditions, and analyzed the main test results, which can provide scientific guarantee for the
safe operation of the mine gas drainage system.

Key words: water ring vacuum pump; performance parameter detection; data conversion to specified conditions; gas volume adjustment
