Clear up button.At this point, controller control unloading valve 20 must be electrically turn off, the first reel control valve 12 obtains electric-opening.Controller output
Certain current value makes hydraulic pump 19 reach a fixed displacement, and hydraulic motor 21 reaches certain motor rotary speed, and then controls high pressure water
Pump 8 reaches certain pump rotary speed, to export the high pressure water of certain water-aspirator pressure.The representative target water pump pressure of controller setting
The preset value of the first pressure regulator valve of setting pressure ratio 11 of power is slightly lower.The outlet of high-pressure hydraulic pump 8 is detected by pressure sensor 9
Real-time water-aspirator pressure, more real-time water-aspirator pressure and setting pressure, if in real time water-aspirator pressure below or above setting pressure,
The hydraulic pump discharge for controlling hydraulic pump 19 carries out corresponding change, makes the water-aspirator pressure of high-pressure hydraulic pump 8 that can maintain stationary value always,
And first pressure regulator valve 11 there is no flooded conditions.
When carrying out lossless excavation, spray gun is connected in the outlet of the hose of the second reel 18, lossless excavation starting is pressed, unloads
Lotus valve 20 must be electrically turn off, and solenoid directional control valve 13 obtains electric-opening, and the second switching control valve 14 obtains electric commutation, the target of controller setting
Pressure value is slightly less than the preset pressure value of the second pressure regulator valve 16, adjustment process phase when hydraulic pressure adjustment process is cleared up with pipeline dirt
Seemingly.
When carrying out cleaning operation, spray gun is connected in the outlet of the hose of the second reel 18, presses cleaning button.At this point,
Unloading valve 20 must be electrically turn off, and the second reel control valve 13 obtains electric-opening, adjusting when hydraulic pressure adjustment process and pipeline dirt are cleared up
Process is similar.In the high pressure water circuit system of the present embodiment, lossless excavation and cleaning operation share the second reel 18, cut by second
It changes the switching of control valve 14 and realizes function switch, it is simple to operation.
When pipeline drain operation, drain button is pressed.At this point, drain valve 4 obtains electric-opening, due to gravity, water tank 1 and height
The clear water in pipeline between water pump 8 is discharged by drain valve 4.After a certain period of time, drain valve 4 is closed, air accumulator control for delay
Valve 6 processed obtains electric-opening, and the first reel control valve 12 obtains electric-opening, the hose of the first reel 15 and the clear water row in respective branch
Out.Postpone certain time, 12 power loss of the first reel control valve is closed, and the second reel control valve 13 obtains electric-opening, and setting second is adjusted
In the branch of pressure valve 16 clear water discharge, postpone certain time, the second switching control valve 14 electric commutation, the second reel 18 it is soft
Clear water discharge in pipe and connection branch, closes drain button after the completion of draining.
From the above description, it can be seen that the high pressure water circuit system of the embodiment of the present disclosure and the dredging with the high pressure water circuit system
Equipment at least one has the following advantages that:
1, it by the motor rotary speed of hydraulic pump control hydraulic motor, to control the pump rotary speed of high-pressure hydraulic pump, and then controls
The water-aspirator pressure of high-pressure hydraulic pump processed, conducive to the pressure control for realizing high-pressure waterway control system under different operating conditions, conducive to height is avoided
Press the overflow of water circuit system superpressure.
2, the drainage pattern draining that high pressure water circuit system is drained using gas and low level gravity drainage combines, draining is thorough,
Equipment is damaged conducive to preventing water circuit system from freezing.
3, high pressure water circuit system and dredging device integrate the cleaning of pipeline dirt, lossless excavation and cleaning function, integration compared with
It is good, space is saved, cost is saved.
4, the control valve using electrically-controlled valve as each control node of high pressure water circuit system is conducive to realize high pressure water circuit system not
It is simple to operation with the one key switching of operating condition.
Finally it should be noted that: above embodiments are only to illustrate the technical solution of the disclosure rather than its limitations；To the greatest extent
Pipe is described in detail the disclosure referring to preferred embodiment, it should be understood by those ordinary skilled in the art that: still
It can modify to the specific embodiment of the disclosure or some technical features can be equivalently replaced, should all cover
In the claimed technical proposal scope of the disclosure.
