Tired and platform of nai high -voltage testing of hydrovalve

The utility model discloses a tired and platform of nai high -voltage testing of hydrovalve relates to the tired and high pressure resistant test field of hydrovalve. Motor (2) drive hydraulic pump (1) provides the power supply for the test system. Overflow valves (4) are used for high pressure of adjustment system and off -load. Proportion overflow valve (6) are used for setting up the test pressure of actual need. High -speed oil channel switching can be realized in servovalve (9) for control pressurized cylinder direction of motion and speed provide pulse stress signal and pressurization signal to the pressurized cylinder. Pressurized cylinder (10) have the pressure amplification effect, produce high -voltage testing pressure pulse under the signalization of servovalve pulse stress. Pressure sensor b (13) are used for gathering the pressure pulse signal and transmit to the industrial computer. The withstand voltage life -span data that are the valve by the time of examination valveappearance damage. Be app
