Reserved multiple fast interfaces, for connecting rear end test platform or test products, as fuel feeding and pressurize test etc.
Accumulator in oil supply system is made supplementary energy equipment, and when hydraulic pump is during to accumulator fuel feeding, accumulator is that pressure energy stores by oil sources Conversion of Energy, and in the time that rear end needs oil sources, accumulator discharges the energy of accumulator. Accumulator provides the hydraulic oil source of certain pressure scope can to each hydraulic test platform or product, when the pressure of oil circuit is during higher than 30MPa, the pressure switch that is arranged on leading portion loop triggers, overflow valve is opened, the oil of now hydraulic pump output is back to fuel tank, thereby stop to accumulator fuel feeding, prevent that energy storage pressure is too high, protection accumulator; When the pressure of oil circuit is during lower than 20MPa value, pressure switch triggers, and overflow valve cuts out, and hydraulic pump starts to accumulator fuel feeding, thereby the pressure that ensures accumulator is at 20-30MPa.
The hydraulic pump of native system adopts variable pump, is the variable pump with pressure controlled proportional displacement control, and the output pressure of this pump and flow can regulate as required. The output flow of pump is corresponding with the signal of telecommunication of front pump controller. Input the corresponding signal of telecommunication to pump controller, can change the output flow of pump.

Pump controller has comprised solenoid-operated proportional pressure pilot valve and pressure sensor, is used in conjunction with electronic control module, can provide pump discharge pressure is carried out to closed-loop control. In the time adopting accumulator fuel feeding, electric-control system is to constant signal of telecommunication of pump controller, and variable pump is used as constant displacement pump and is used. When the follow-up variable function that can adopt pump need to change flow time.
The course of work of this hydraulic oil supply system is as follows:
When starter motor, overflow valve dead electricity is opened, hydraulic pressure delivery side of pump hydraulic oil oil return case, and motor is not with to carry and is started like this, to protect motor. After electric motor starting, overflow valve obtains electric cut-off, and hydraulic pump is to accumulator fuel feeding. In the time detecting that in petroleum pipeline, oil pressure exceedes 30MPa, electric control gear controlling water kick valve dead electricity, hydraulic pump stops to accumulator fuel feeding, and system pressure no longer raises. Accumulator after test platform or product fuel feeding, pressure drop, when pressure is during lower than 20MPa, electric control gear controlling water kick valve obtains electric cut-off. Hydraulic pump, to accumulator fuel feeding, raises energy storage pressure. By the control of electric control gear, ensure that the pressure of accumulator is at 20-30MPa. Frequently change startup for fear of motor, when the accumulator short time is when fuel cut-off, not disable motor, just closing outflow valve, allows hydraulic pump unloading. In the time that accumulator does not need fuel feeding for a long time, just disable motor.
A more traditional test platform of this hydraulic oil supply system needs a motor and hydraulic pump fuel feeding respectively, has saved cost, in factory building management, can use flexibly as required effectively simultaneously. Adopt constant flow fuel feeding variable-flow fuel feeding, of many uses.
To sum up: the utlity model has following beneficial effect:
