Device for powerful type high speed press hydraulic pressure overload protection

Device for powerful type high speed press hydraulic pressure overload protection transships installation pressure relay (8) and relief plug (9) in pump (1), transship pump (1) through high pressure fuel pipe (14) and two-position three way solenoid valve (6) connection, overload pump (1) two is ventilated accuse formula magnetic ball valve (7) and is connected with you through air supply pipe (13). Simple structure, convenient operation, on and off control is accurate quick, has improved work efficiency, and normal production in the use, has been guaranteed to the even running of protective apparatus safety and equipment work, and it is stable to have improved product quality, has prolonged the mould and has repaiied the mould cycle, behind the troubleshooting, the work of in time renewaling effectively realizes the overstrain protection.
