Problems solved by technology

[0003] Most of the existing reciprocating plunger pumps have a motor that drives the piston inside the pump body to reciprocate through a belt, and the pressurized liquid is discharged through a high-pressure oil pipe through a one-way check valve. Once pressurized, it is impossible to actively and conveniently adjust the volume of the working chamber

Abstract

The invention discloses a reciprocating plunger pump, which comprises a base, a power source mechanism, a reciprocating drive mechanism and a piston mechanism. The beneficial effects achieved by the invention are: a servo motor drives a transmission gear roller to rotate through a transmission belt, and the transmission gear When the roller rotates, it can drive the two transmission gears meshed with it to rotate. When the transmission gear rotates, it can drive the two fixed rods to rotate in a circle with the transmission shaft as the center of the circle. The fixed rod can be driven by the transmission rod when it rotates in a circle. The piston rod and the piston block perform piston movement inside the piston sleeve, and when the two piston blocks perform piston movement inside the two piston sleeves, they can be pressurized multiple times, so that the high-pressure oil on the first piston sleeve is discharged. The oil pressure discharged from the pipe increases, and the lead screw disposed at the end of the piston sleeve can drive the sealing block to move inside the piston sleeve, so that the volume of the working cavity between the piston sleeve and the piston block can be adjusted.

Description

technical field [0001] The invention relates to a reciprocating plunger pump, belonging to the technical field of plunger pumps. Background technique [0002] Plunger pump is a kind of positive displacement pump. It relies on the reciprocating piston or plunger in the pump cylinder to change the volume of the working chamber, so as to achieve the suction and discharge of liquid. Because of the main working part in the pump cylinder, the piston or plunger, it is called a plunger pump. Used in the oil field industry, it is usually used to inject liquid into the subterranean formation, so it is also called oil field injection pump. It is usually composed of two parts, the power end and the hydraulic end, with packing box assembly, box body, base assembly, belt, check valve, safety valve, buffer, etc. [0003] Most of the existing reciprocating plunger pumps have a motor through a belt to drive the piston inside the pump body to reciprocate, and a one-way check valve is used t...
