Abstract

The invention discloses a system and a method for detecting changes of differential pressure of a gas filter. The system is connected with the detected gas filter and comprises a system pipeline, a detection medium and multiple elements, the multiple elements are connected through the system pipeline, and the detection medium is a liquid working medium; the multiple elements comprise a storage box, a first purifying filter, a second purifying filter, a variable pump, a pressure gauge, a differential pressure sensor, a flow meter, a flow-limiting valve and an overflow valve. The liquid working medium is used for testing changes of differential pressure of the gas filter, the system pressure can be reduced, the test system can be simplified, the safety of the test can be improved, additionally, the preparation procedure for the detected product accessing to the system can be simplified, the test efficiency is improved, and the test cost is reduced.

Description

technical field [0001] The invention relates to the field of pneumatic transmission, in particular to a system and method for detecting pressure difference changes of gas filters. Background technique [0002] The high-pressure gas filter is a device that filters gas through a built-in filter material. [0003] In the actual use process, due to the continuous accumulation of dust particles and other residues in the gas on the filter material, the pores of the filter material will be gradually blocked, the effective flow area of ​​the filter will continue to decrease, and the local resistance of the filter will gradually increase, which will eventually affect the supply. The downstream working pressure and system flow of the gas system. [0004] Therefore, the effective flow area of ​​the gas filter needs to be detected after being used for a period of time to determine whether it can continue to be used. If the surface filter is used to clean the filter material, it is als...
