The invention discloses a high-pressure
plunger pump with an
energy recycling function and relates to the technical field of hydraulic
energy recycling. The problem that many energy transmission links exist in the
energy recycling process is solved. The high-pressure
plunger pump with the energy recycling function comprises an outer shell and a cylinder body, wherein the outer shell comprises two end covers and a shell body with a through hole; the cylinder body is arranged in the through hole of the shell body; a
swash plate is arranged between the cylinder body and one of the end covers; cylinder holes are formed in the cylinder body in a circumferential array; a
plunger and sliding shoe
assembly is arranged in each cylinder hole; the outer shell is provided with a fluid inlet and a fluid outlet which communicate with the cylinder holes; a fluid channel is arranged on the cylinder body; a hydraulic cavity is formed between each plunger and sliding shoe
assembly and the inner wall of the corresponding cylinder hole and communicates with the fluid channel; the outer shell is provided with a recycling inlet and a recycling outlet which communicate with the fluid channel. The high-pressure
plunger pump with the energy recycling function is mainly applied to high-pressure fluid equipment for industrial production to achieve the functions like recycling energy of waste high-concentration sea water in reverse-
osmosis seawater.
