The pumping pump receives the oil of the hydraulic tank, then pilot the oil to discharge the oil through the pipe filter to the safety solenoid valve, and the oil is filtered through the pipe filter. Hyundai excavator oil absorbing circuit, oil supply loop and return loop
The oil volume discharged from the pilot pump flows through the pipeline filter into the remote control valve, EPPR valve (electromagnetic proportional pressure regulator), solenoid valve assembly, rotary stop brake, main control valve, and safety locking solenoid valve.ฤก. The pilot pump is equipped with a relief valve, and the oil of the hydraulic tank is received by the oil absorbing filter. The lead circuit includes an oil absorbing circuit, oil supply circuit and an oil return circuit.
