Brief description of the drawings
Accompanying drawing described herein is used for providing further understanding of the present application, forms the part of the application, this Shen
Schematic description and description please is used to explain the application, does not form the improper restriction to the application.In the accompanying drawings：
Fig. 1 is the hydraulic control system configuration schematic diagram of accumulator in the embodiment of the present application.
Embodiment
To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with the application specific embodiment and
Technical scheme is clearly and completely described corresponding accompanying drawing.Obviously, described embodiment is only the application one
Section Example, rather than whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing
Go out under the premise of creative work the every other embodiment obtained, belong to the scope of the application protection.
The embodiments of the invention provide a kind of hydraulic control system of accumulator, as shown in figure 1, including accumulator 1, fuel tank
2nd, high pressure fuel source, controller (not shown), enter fuel-displaced operating valve and disengaging oil control valve.
In the present embodiment, high pressure fuel source is oil pump 3, and controller is PLC 4, enters fuel-displaced operating valve and is changed for electromagnetism
To valve 5, disengaging oil control valve is inserted valve 6.
The sensor 7 for detecting its hydraulic pressure size is connected with the accumulator 1, the sensor 7 is controlled with the PLC
Device 4 processed electrically connects, and the solenoid directional control valve 5 includes actuator port 51, oil return opening 52, pressure oil port 53, and the inserted valve 6 includes
Hydraulic control hydraulic fluid port 61, oil inlet 62 and oil-out 63, the actuator port 51 is connected with the hydraulic control hydraulic fluid port 61, described
Oil return opening 52 is connected with the fuel tank 2, and the pressure oil port 53 is connected with the oil pump 3, the oil-out 63 and the accumulation of energy
The hydraulic oil charge and discharge mouth of device 1 is connected, and the oil inlet 62 is connected with the oil pump 3, and the solenoid directional control valve 5 is controlled with the PLC
Device 4 processed electrically connects.
The technical program detects the hydraulic pressure size of accumulator using sensor and controls testing result real-time Transmission to PLC
Device, meanwhile, solenoid directional control valve and inserted valve coordinate, and PLC is by controlling solenoid directional control valve to obtain electric, dead electricity, so as to control
The conducting and cut-off of inserted valve, to realize the Oil feeding process of accumulator, so as to intelligently control the hydraulic pressure of accumulator, improve efficiency
While can also improve the precision of energy storage pressure.
In the present embodiment, in order to prevent the hydraulic oil in accumulator 1 to be back to inserted valve, in the oil-out 63 and described
