Main functional test items:
1. Overload test: maximum displacement, 110% of rated pressure or 5-10min under maximum pressure.
2, impact test: manual control pressure impact test.
3, external leakage: in the above test, check the leakage of the sealing part.
4, system pressure: up to 30Mpa; The system pressure and test pressure are respectively 40MPa shock-proof pressure gauge display.
5, the number of tests: one cylinder, you can set multiple stations
6, with the collection and display of test data, printing function;
7, with the over-limit alarm function in the test process;
8, can test the hydraulic cylinder, starting pressure test, pressure test, leakage/leakage test, stroke inspection, etc.
