Abstract

The invention provides a plunger pump. The plunger pump comprises a valve body, a drive transfer portion and a displacement regulating portion. The valve body consists of a main valve body, a left valve body and a right valve body, the valve body is provided with a fluid flow passage communicated with an oil inlet and an oil outlet, flow-limiting valves for controlling the oil inlet and the oil outlet to open and close are arranged in the fluid flow passage, the main valve body is provided with a hermetic hydraulic cavity communicated with the fluid flow passage, and a plunger is arranged in the hydraulic cavity. The drive transfer portion comprises a connecting rod and a regulating seat, the upper end of the connecting rod is hinged to the bottom end of the plunger, and the lower end of the connecting rod is hinged to the regulating seat. The displacement regulating portion is arranged in the regulating seat and comprises a regulating block, a hinge joint shaft and a regulating drive part, wherein the regulating block is embedded into the regulating seat, the hinge joint shaft is fixedly connected to the regulating block, and the regulating drive part is used for regulating the position of the hinge joint shaft. The plunger pump is capable of providing precise displacement according to different displacement needs.

Description

technical field [0001] The invention relates to a pump, in particular to a plunger pump. Background technique [0002] The plunger pump is a positive displacement pump, which is driven by an electric motor and connected to the piston rod through a reduction box and a crank connecting rod mechanism to make the piston reciprocate. It relies on the reciprocating movement of the piston and sequentially opens the suction valve and the discharge valve to suck in and discharge the liquid. Its working principle is: with the reciprocating movement of the piston, when the volume of the working chamber increases, a low pressure is formed, and the liquid in the liquid storage tank can be sucked into the pump cylinder through the suction valve. When the liquid is sucked, the discharge valve is closed due to the liquid pressure in the discharge pipe. Afterwards, when the volume of the working chamber decreases, the liquid in the pump cylinder is squeezed to increase its pressure, so tha...
