The invention discloses a suction filter pressure drop testing device and a suction filter testing system. The suction filter pressure drop testing device comprises a first mounting plate, a second mounting plate and a differential pressure testing assembly, the first mounting plate is provided with a first mounting surface, and a first oil hole is formed in the first mounting surface in a penetrating manner. The second mounting plate is arranged on the first mounting surface, a second oil hole is formed on the end face, corresponding to the first mounting plate, of the second mounting plate in a penetrating mode, and a containing cavity is formed between the second mounting plate and the first mounting plate, communicates with the first oil hole and the second oil hole and is used for sealing and mounting a suction filter to be tested. The differential pressure testing assembly comprises a differential pressure gauge, one of a high-pressure port and a low-pressure port of the differential pressure gauge is communicated with the first oil hole, and the other one is communicated with the second oil hole, so that the pressure drop index is detected, the oil flow passing through the first oil hole is ensured, and the test stability is ensured.
Description
technical field [0001] The invention relates to the technical field of testing and detection, in particular to a suction filter pressure drop testing device and a suction filter testing system. Background technique [0002] One of the most important items in the performance of the suction filter is the pressure drop characteristic of the suction filter. The pressure drop refers to the pressure drop caused by the oil passing through the suction filter product at a specific temperature and flow rate. If the pressure drop is too large, it will cause the suction of the back-end oil pump and affect the performance of the oil pump; but it is not The smaller the better, considering the other characteristics of the suction filter and economical efficiency, a suitable pressure drop index is required. In order to confirm whether the pressure drop characteristics of the suction filter meet the design requirements, corresponding tests need to be carried out. [0003] The existing sucti...
