Abstract

The invention relates to a vacuum pump testing system and method. The vacuum pump testing system comprises first and second vacuum chambers, first and second pressure testing systems, gas supply equipment, first and second gas pumping equipment, gas flow testing and controlling equipment and first and second temperature control equipment, wherein the first and second vacuum chambers are used for being connected with an air suction inlet and an air exhaust outlet of a pump chamber to be tested correspondingly, the first and second pressure testing systems are used for measuring the pressure ofthe first and second vacuum chambers correspondingly, the gas supply equipment provides gas for the first and second vacuum chambers, the first and second gas pumping equipment pumps gas from the first and second vacuum chambers correspondingly, the gas flow testing and controlling equipment is used for measuring and controlling the gas flow of the first vacuum chamber, and the first and second temperature control equipment controls the temperature of the first and second vacuum chambers correspondingly. The vacuum pump testing method is applied to the vacuum pump testing system. The vacuum pump testing system and method can provide pressure, flow and temperature controllable testing environment, can simulate the gas pumping states of a vacuum pump under different conditions, and can be used for testing gas pumping performance of different kinds of vacuum pumps.

Description

technical field [0001] The invention relates to a vacuum pump testing system and testing method. Background technique [0002] Vacuum pumps, especially dry vacuum pumps, need to be tested based on the pressure, flow and temperature changes of the vacuum pump during the design and production process. However, the existing measurement methods can basically only adjust the flow rate, and cannot test the pumping performance of different types of vacuum pumps under different conditions by controlling the temperature, pressure and flow rate. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide a vacuum pump testing system and testing method that can simulate the pumping state of the vacuum pump under different conditions and can be used for testing the pumping performance of different types of vacuum pumps. [0005] (2) Technical solutions [0006] In order to achieve the above object, the main techn...
