Common faults and troubleshooting of hydraulic plate shears

Because of the flexibility and convenience of hydraulic transmission control, hydraulic control is widely valued in industry.

Hydraulic transmission is the study of pressure fluid as the energy medium, to achieve a variety of mechanical and automatic control disciplines.

Hydraulic transmission uses this element to form the required control loop, and then by a number of circuits organic combination to complete a certain control function of the transmission system to complete the transfer, conversion and control of energy.

Common faults and troubleshooting of hydraulic plate shears:

1. The oil circuit cannot be established without pressure, and the tool rest cannot move

Cause: The electric plug of the electromagnetic directional valve is not in good contact; Repair electrical plugs.

Elimination method: solenoid directional valve spool is sundry stuck or hair and do not act, the combination valve valve valve seal mouth has sundry and does not have the sealing effect, the combination valve in the throttling hole blocked; Check the unpick and wash

2. The tool rest return is slow or can not return to the top dead point. The tool rest and the pressure cylinder action sequence is not coordinated

Cause: The nitrogen pressure in the nitrogen cylinder is insufficient

Elimination method: nitrogen cylinder inflation to increase the pressure.
