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.
