For achieving the above object, technical solution adopted in the utility model is as follows:
A piston super charger for large hydraulic press, comprising:
At least one piston cylinder, described piston cylinder is made up of low-pressure cavity and hyperbaric chamber,
The hyperbaric chamber of described piston cylinder is connected with pressure-loaded prefilling tank by piston cylinder input end, and is connected with press clutch release slave cylinder by piston cylinder output terminal,
The low-pressure cavity of described piston cylinder is connected with high-pressure service pump and pressure pan by the input end of distributor, and the output terminal of described distributor is communicated with atmospheric water tank.
Preferably, between the piston cylinder input end and pressure-loaded prefilling tank of described hyperbaric chamber, between the piston cylinder output terminal of hyperbaric chamber and press clutch release slave cylinder, be provided with one-way valve, described one-way valve defines flow direction, guarantees that liquid can only flow to piston cylinder input end and liquid can only flow to press clutch release slave cylinder from piston cylinder output terminal from pressure-loaded prefilling tank.
Preferably, described piston cylinder has two, and two piston cylinders are arranged at respectively pressure-loaded prefilling tank both sides, and each piston cylinder input end all connects pressure-loaded prefilling tank, after each piston cylinder output terminal interconnects, is communicated with press clutch release slave cylinder.
Preferably, on the piston cylinder output terminal of hyperbaric chamber one side of described piston cylinder, be provided with pressurize hydraulic control safety overflow valve.
By above technological scheme, the beneficial effects of the utility model are:
1, simple in structure, without external force framework, weight is little, and can effectively save investment;
2, by the pressurize hydraulic control safety overflow valve arranging at output terminal, can be in the time exceeding system when s and set pressure, by overflowing partially liq to guarantee stablizing of system pressure.
