Specific embodiment
The utility model is further described with specific implementation with reference to the accompanying drawing:
As shown in Figure 1, economical servopump controls bender hydraulic system, by fuel tank 1, oil filter 2, servo motor 3, oil
Pump 4, safety valve 5 and cavity of resorption safety valve 10, two-position four-way solenoid valve 6, check valve I 7 and check valve II 12, three position four-way electromagnetic valve
8, counterbalance valve 9, cavity of resorption safety valve 10, Solenoid ball valve 11, oil cylinder 13, prefill valve 14 form；Oil pump 4 is controlled by servo motor 3,
Inlet port installation oil filter 2 protrudes into fuel tank, and safety valve 5 is arranged in oil outlet, and oil outlet is separately connected the P of two-position four-way solenoid valve 6
The P mouth of mouth, the T mouth of check valve I 7, three position four-way electromagnetic valve 8, the B mouth of two-position four-way solenoid valve 6 are connected to prefill valve control mouth,
Check valve I 7 P mouth connection the P mouth of check valve II 12, the T mouth of cavity of resorption safety valve 10, three position four-way electromagnetic valve 8 T mouth, three
The T mouth of the T mouth of the A mouth connection counterbalance valve 9 of four way solenoid valve 8, Solenoid ball valve 11, the B mouth of three position four-way electromagnetic valve 8 are connected to oil
