Drain tap enters oil cylinder through reversal valve and one of flowmeter；Pressure-reducing valve oil-out to be measured is through counterbalance valve and another flowmeter
Into oil cylinder；
The oil-out of pressure-reducing valve is surveyed in pressure gauge reception；Thermometer connects oil cylinder；
The electric control unit includes PLC, display control unit, data acquisition unit, oil pump control unit；
PLC gathers the control information of display control unit input, by display control unit display data information, passes through data
The data of collecting unit collection pressure gauge, thermometer and flowmeter, the operating of hydraulic pump is controlled by oil pump control unit.
When carrying out pressure adjustment with flow detection, back pressure valve regulation to certain pressure, then one-way throttle valve is adjusted
Oil circuit flow and pressure are controlled, PLC gathers the data of flowmeter by data acquisition unit.Pressure adjustment is carried out to examine with amount of leakage
During survey, amount of leakage under different pressures is can obtain by adjusting one-way throttle valve.Counterbalance valve is closed, reversal valve is opened, by changing
It is the leakage rate of pressure-reducing valve to be measured to the flow of valve.
According to compared with prior art, the utility model can automatically control hydraulic pump, automatic data collection pressure using PLC
