Problems solved by technology
[0002] With the development of hydraulic transmission technology in the direction of high pressure, high efficiency, long life, integration, and intelligence, micro hydraulic pumps have good application prospects and can be widely used in intelligent hydraulic equipment such as aviation, aerospace, and navigation. The matching pressure adjustable, micro-flow hydraulic pump test system is in urgent need of matching
[0003] The existing hydraulic pump test system mainly tests traditional hydraulic pumps. The inlet pressure of the hydraulic pump to be tested cannot be adjusted, the test flow rate is large, and the test method is fixed. Moreover, the structure of the traditional hydraulic pump test platform is complex, and the performance parameters of the hydraulic pump to be tested are few and the degree of automation is low. Low, low test efficiency
For micro-flow high-pressure plunger testing, the traditional experimental platform can no longer fully meet the requirements
