When the system fast-forwards, the first pump 14 and the second pump 15 act simultaneously to provide the maximum flow for the system, so that the system can move rapidly without load. When the system is in operation, the first pump 14 acts to provide sufficient power for the system. When the system finishes pressure relief, the two-way cartridge valve ten 10 acts to realize pre-unloading, reduce the vibration of the system and prolong the service life of elements. When the system returns, the return speed is realized through two-stage return of a two-way cartridge valve twelve 12 and a two-way cartridge valve thirteen 13.

The working principle is as follows:

two-way cartridge valves I1, three-way cartridge valves III 3, five-way cartridge valves 5, six-way cartridge valves 6, seven 7, eight 8, nine 9, ten 10, eleven 11, twelve 12 and thirteen 13 are respectively matched with two-position four-way solenoid valves YA1, two-position four-way solenoid valves YA2, two-position four-way solenoid valves four YA4, two-position four-way solenoid valves ten YA10, two-position four-way solenoid valves eleven YA11, two-position four-way solenoid valves twelve YA12, two-position four-way solenoid valves six YA6, two-position four-way solenoid valves five YA5, two-position four-way solenoid valves seven YA7, two-position four-way solenoid valves two YA2 and two-position four-way solenoid valves nine YA 9;

when the system is fast-forwarding: the two-position four-way electromagnetic valve YA1, the two-position four-way electromagnetic valve YA2, the two-position four-way electromagnetic valve Hexa YA6, the two-position four-way electromagnetic valve eleven YA11 and the two-position four-way electromagnetic valve twelve YA12 are electrified simultaneously, the pump I14 passes through the one-way valve I2, the pump II 15 passes through the one-way valve II 4, after the full-displacement oil liquid of the two pumps is converged, the oil liquid rapidly enters a rodless cavity of the oil cylinder through the two-way cartridge valve nine 9, a piston rod rapidly moves forwards, and the oil liquid in a rod cavity of the oil cylinder returns to an oil tank through the two-way cartridge valve seven 7 and the two-way cartridge valve eight 8. The double pump action, full displacement supply, makes the system move rapidly. When the system is started, the system can carry out fast forward operation when oil is quickly supplemented to the oil cylinder.

This can be done when the actuator is pressurized.

When the system is in pressure maintaining: all electromagnets are uniformly distributed to work. The system may be subjected to a hold pressure operation for a period of time. This pressure holding operation is necessary to prevent the workpiece from rebounding for a certain period of time after the pressurization.

When the system is depressurized: the two-position four-way solenoid valve five YA5 two-way cartridge valve acts. A part of the pressure oil in the rodless cavity of the oil cylinder is discharged through the two-way cartridge valve 10, so that the situation that the vibration is too large due to the fact that the system returns immediately after working is completed, and pre-pressure relief is needed before the system returns is avoided.

When the system is micro-back: the two-position four-way solenoid valve YA1, the two-position four-way solenoid valve YA4, the two-position four-way solenoid valve WYA 5 and the two-position four-way solenoid valve YA10 are powered simultaneously. And oil in the first pump 14 enters a rod cavity of the oil cylinder through the check valve II 4, the two-way cartridge valve VI 6 and the two-way cartridge valve VII 7, so that the oil cylinder returns, and the oil in the rodless cavity flows back to the oil tank through the ten 10 paths of the two-way cartridge valve to complete the micro-return action.

When the system slows back: the two-position four-way solenoid valve YA1, the two-position four-way solenoid valve YA4, the two-position four-way solenoid valve WYA 5, the two-position four-way solenoid valve QIYA 7, the two-position four-way solenoid valve YA8 and the two-position four-way solenoid valve YA10 are powered simultaneously. And oil in the first pump 14 enters a rod cavity of the oil cylinder through the one-way valve I2, the two-way cartridge valve VI 6 and the two-way cartridge valve VII 7, so that the oil cylinder returns, and the oil in the rodless cavity flows back to the oil tank through the two-way cartridge valve Ten 10, the two-way cartridge valve eleven 11 and the two-way cartridge valve twelve 12 to finish slow return action.

When the system is going back fast: the two-position four-way solenoid valve YA1, the two-position four-way solenoid valve YA4, the two-position four-way solenoid valve WYA 5, the two-position four-way solenoid valve QIYA 7, the two-position four-way solenoid valve octaYA 8, the two-position four-way solenoid valve nine YA9 and the two-position four-way solenoid valve decaYA 10 are electrified simultaneously. And oil in the first pump 14 enters a rod cavity of the oil cylinder through the one-way valve I2, the two-way cartridge valve VI 6 and the two-way cartridge valve VII 7 to return the oil cylinder, and oil in a rodless cavity flows back to the oil tank through three paths of the two-way cartridge valve eleven 10, the two-way cartridge valve eleven 11, the two-way cartridge valve twelve 12, the two-way cartridge valve eleven 11 and the two-way cartridge valve thirteen 13, and at the moment, the system returns at the maximum flow to finish quick return action.
