Abstract

The invention provides a slush pump assembly and relates to the field of hydraulic pumps. The slush pump assembly comprises at least one group of working systems, wherein each group of working systems consists of a power end and hydraulic ends, the power end is a linear reciprocating motor, and both ends of an active cell shaft of the linear reciprocating motor are respectively connected with the hydraulic ends. The slush pump assembly is a front and rear double fluid end. When a motor conducts front-end motion, a motor shaft simultaneously drives a front double piston and a rear double piston to conduct reciprocating motion, so that a cylinder is extracted, and simultaneously the other cylinder discharges pressure. After multiple cylinders are connected in parallel, a position of a piston is adjusted, and fluid drainage capacity can be achieved constantly. Multiple pumps are connected in parallel to reach large discharge capacity in parallel according to requirements.

Description

technical field [0001] The invention relates to the field of liquid pumps, in particular to a multi-cylinder mud pump powered by a linear reciprocating motor for oil drilling. Background technique [0002] The mud pumps in the prior art are mechanically driven by gears, which have the disadvantages of short stroke, short piston life, fast reciprocating frequency, and easy wear and tear. Contents of the invention [0003] The object of the present invention is to provide a mud pump system assembly with a linear reciprocating motor as the power end, double hydraulic ends at the front and rear, multiple parallel connection, long stroke, long piston life, adjustable stroke, pressure and displacement. [0004] The technical solution for achieving the above purpose is: a mud pump assembly, characterized in that it includes at least one set of working systems, each set of working systems includes a power end and a hydraulic end, the power end is a linear reciprocating motor, and ...
