Step by step "meticulous", hydraulic system debugging steps

Hydraulic system occupies an important position in the equipment, so in debugging need to follow the instructions or formal steps. Before entering the formal commissioning, you need to do the preparatory work.

Inspection before commissioning

Check and confirm the branch of solenoid valve operated by each hydraulic cylinder according to system schematic diagram, assembly drawing and piping diagram.

Electromagnetic valve for no-load reversing, to confirm whether the electrical action is correct and flexible, the action sequence to meet the requirements.

The stop valve of the pump oil suction pipe and the return oil pipeline is opened, the outlet valve of the pump and the safety valve handle of the system need to be released completely, and the pressure reducing valve is placed at the lowest pressure position.

The opening position is positioned at the flow control valve.

Make clear the instructions and fill the accumulator with nitrogen.

Start the hydraulic pump

The interference between the motor and the hydraulic pump is confirmed by the coupling between the hand disk motor and the hydraulic pump.

Point motor, check to determine whether the motor steering is consistent with the hydraulic pump steering signs, after confirmation of the continuous point of several times, no abnormal circumstances, press the motor start button, hydraulic pump began to work.
