Fault one: no pressure in hydraulic system 30t hydraulic press brake . 1. Whether the solenoid coil of the proportional relief valve is energized and whether the voltage of the proportional solenoid coil meets the requirements. For the above reasons, please check the related electrical reasons. 2. Check whether the cartridge valve is jammed or the main spool is jammed, and the damping hole is blocked. If it is for the above reasons, please remove the overflow valve, clean it,… Leer Más "How to solve the common faults of 30t hydraulic press brake

Bending press brake machine by the fuselage, torsion shaft, slider, stroke adjustment, front supporting frame, rear retaining frame, mold, hydraulic system, electrical system and other nine parts.
