Embodiment Construction
[0024] Such as figure 1 As shown, a vapor flow vacuum pump performance automatic measurement system includes a test cover 11, a tested vapor flow vacuum pump 13, a backstage pipeline 18, a backstage mechanical pump 19, a gas flow test unit, a test cover gas flow adjustment unit and a front stage The first-stage pipeline gas flow adjustment unit; the measured vapor flow vacuum pump 13 is connected to the fore-stage pipeline 18 and the fore-stage mechanical pump 19 in sequence.
[0025] The inner diameter of the test cover 11 is the same as the inlet diameter of the tested vapor flow vacuum pump 13, and the two are connected by a flange. A test cover vacuum gauge 12 is connected to the test cover 11 , and the computer control unit 20 reads the actual balance pressure value in the test cover 11 through the test cover vacuum gauge 12 .
[0026] The gas flow test unit includes an oil tank, measuring oil 1 and a dropper 3, a dropper electromagnetic valve 5 is arranged at the air in...
