Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face, which combines to be specifically illustrating, is further described the utility model.
Referring to Fig.1, a kind of combination hydraulic pumping station system, the active including unidirectional variable pump 5 as pumping station system pumps, double
It is used as slave pump to variable pump 13, two-way quantitative pump 7 is as pumping station system compensation pump.Wherein, unidirectional variable pump 5 and two-way quantitative
Pump 7 is all made of pipeline road with fuel tank 6 and connect.Pipeline road between unidirectional variable pump 5 and two-way quantitative pump 7 uses two-position four-way
Reversal valve 3 is attached, and third check valve 17 is equipped between unidirectional variable pump 5 and two-position four way change valve 3.Two-way quantitative pump 7
Second one-way valve 9 and principal pressure table 16 are equipped between two-position four way change valve 3.13 place branch road of two-way variable displacement pump be provided with
The stacked unidirectional throttle valve 12 and shut-off valve 14 that two-way variable displacement pump 13 is connected directly, in stacked unidirectional throttle valve 12 and main pressure
Solenoid directional control valve 11, branch pressure table 15, the second pressure reducing valve 10 and the first check valve 8 are successively arranged between power table 16.Two-position four-way
Reversal valve 3 is also connected with overflow valve 4, for pump oil extra in pipeline road to be timely discharged.
In use, close by second one-way valve 9 first makes two-way quantitative pump 7 be not at working condition；It connects at this time
