No pressure in the press

1. Appropriately increase the diameter of the damping hole of the main valve core. Under normal circumstances, the diameter of the damping hole of the domestic standard overflow valve is 0.8-1.5mm, which can be changed to 1.5-1.8mm. This does not have much effect on the static characteristics, but the lag time can be greatly reduced and the pressure can rise quickly. 2. Disassemble and clean the main valve and pilot valve, and use a 0.8-1.0m steel wire to pass the damping hole of the main valve...

Oil leakage fault diagnosis of C-type hydraulic press

1. Poor pipe bending: When installing hard pipes, the specified bending radius must be followed. If the bending radius is too small, the pipe surface will gradually become thinner, wrinkles will appear on the inner wall, resulting in increased bending stress and decreased pipe strength. Under strong vibration or external pressure shock, the pipe is prone to horizontal cracks and oil leakage. The installation of the hose also requires attention, and improper bending will cause hose damage and...
