1. The main valve heart hole of the 315-ton single-arm hydraulic press is blocked. If the hydraulic pressure does not inform the upper chamber of the main valve and the front chamber of the cone valve, the pilot valve will lose its perception of the pressure of the main valve. as a result of single arm hydraulic machine main valve of the upper chamber there is no oil pressure, so elastic small, main valve...
