It is connected to the oil inlet A4 of the first hydraulic motor 4, waiting than another oil outlet of flow divider-combiner 2 B22 is to be connected to the second hydraulic horse
Up to 5 oil inlet A5；The oil outlet B4 of first hydraulic motor 4 is connected to the oil return opening B1 of Closed Hydraulic plunger pump 1, and second
The oil outlet B5 of hydraulic motor 5 is also connected to the oil return opening B1 of Closed Hydraulic plunger pump 1.
The hydraulic system further includes having the first solenoid directional control valve 3, and the first solenoid directional control valve 3 is with the first hydraulic motor 4
Be arranged in parallel, oil inlet A3 connection of the first solenoid directional control valve 3 etc. than flow divider-combiner 2 one of oil outlet B21, first
The oil outlet B3 of solenoid directional control valve 3 is connected to the oil return opening B1 of Closed Hydraulic plunger pump 1.
The hydraulic system further includes having the second solenoid directional control valve 6, and the second solenoid directional control valve 6 is with the second hydraulic motor 5
It is arranged in parallel, another oil outlet B22 than flow divider-combiner 2 such as oil inlet A6 connection of the second solenoid directional control valve 6, the second electricity
The oil outlet B6 of magnetic reversal valve 6 is connected to the oil return opening B1 of Closed Hydraulic plunger pump 1.
When dam paver starts or is in standby, pump engine drives Closed Hydraulic plunger pump 1 to work, enclosed
1 discharge capacity of hydraulic planger pump becomes zero, i.e., no flow output, the first solenoid directional control valve 3 and the second solenoid directional control valve 6 must not be electric,
First hydraulic motor 5 and the second hydraulic motor 6 do not work.
When dam paver works normally, pump engine drives Closed Hydraulic plunger pump 1 to work, Closed Hydraulic plunger pump
1 slippage pump is realized by adjusting the discharge capacity of Closed Hydraulic plunger pump 1 to dam paver enclosed at this time from 7 oil suction of hydraulic oil container

The oil inlet A3 of reversal valve 3, then the oil outlet B3 through the first solenoid directional control valve 3 flow back into the oil return opening of Closed Hydraulic plunger pump 1
B1；The hydraulic oil for flowing out oil outlet B22 simultaneously passes through the oil inlet A5 of hydraulic motor 5, then the oil outlet B5 through hydraulic motor 5 is returned
The oil return opening B1 for flowing to Closed Hydraulic plunger pump 1, is finally completed entire working cycles.
When needing a motor of system not work, workflow principle is similar with said one motor operations: opening
First solenoid directional control valve 3 and the second solenoid directional control valve 6, the discharge capacity realization by adjusting Closed Hydraulic plunger pump 1 pave to dam
The speed of machine enclosed auger system is adjusted, oil-feed port A1 of the hydraulic oil through enclosed hydraulic planger pump 1 after adjusting flow to equal ratios
The oil inlet A2 of flow divider-combiner 2 is diverted to oil outlet B21 and oil outlet B22 than ratios such as flow divider-combiners 2 through equal, due to stream
Body flows to pressure lower principle, and the hydraulic oil of outflow oil outlet B21 passes through the oil inlet A3 of the first solenoid directional control valve 3, then through the
The oil outlet B3 of one solenoid directional control valve 3 flow back into the oil return opening B1 of Closed Hydraulic plunger pump 1；The liquid of oil outlet B22 is flowed out simultaneously
Pressure oil passes through the oil inlet A6 of the second solenoid directional control valve 6, then the oil outlet B6 through the second solenoid directional control valve 6 flow back into Closed Hydraulic
The oil return opening B1 of plunger pump 1 is finally completed entire working cycles.
This system can also be achieved motor reverse function, and oil circuit flow direction is just with normal operation on the contrary, i.e. from enclosed liquid
The oil return opening B1 outflow of hydraulic plunger pump 1 after the acting of each motor, through it is equal than flow divider-combiner 2 by its oil outlet B21 and oil outlet
Hydraulic oil of B22 etc. flows to oil inlet A2 than collection, finally flows back into the oil-feed port A1 of Closed Hydraulic plunger pump 1, realizes entire work
It recycles.
Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly
Interest field, therefore equivalent variations made according to the claim of the utility model still fall within the scope of the utility model.
