Abstract
The invention discloses a piston-type supercharger of a large hydraulic machine. The piston-type supercharger comprises at least a piston cylinder, wherein the piston cylinder is composed of a low-pressure cavity and a high-pressure cavity, the high-pressure cavity of the piston cylinder is communicated with a liquid filling tank through the input end of the piston cylinder and communicated with a press work cylinder through the output end of the piston cylinder, the low-pressure cavity of the piston cylinder is communicated with a high-pressure pump and a high-pressure tank through the input end of a distributor, and the output end of the distributor is communicated with a normal-pressure water tank. When the piston-type supercharger works, high-pressure liquid output by the high-pressure tank and the high-pressure pump is allocated to the low-pressure cavity of the piston cylinder through the distributor and pushes a piston to move. Super-high-pressure liquid is generated at the small-area end of a piston rod of the high-pressure cavity and is conveyed to the press work cylinder through the output end by means of a singe-way valve, the supercharging process is achieved, and the piston-type supercharger has the advantages of being simple in structure, free of external force framework and low in weight and can effectively save investment.
