Problems solved by technology

The reduction in speed directly leads to a decrease in the output flow of the pump
These are the contradictions where it is difficult for conventional plunger pumps to achieve large flow rates, which is their Achilles heel

Abstract

The invention relates to the field of sea water pumps, in particular to a radial multi-row vertical piston pump. The radial multi-row vertical piston pump comprises a stator 1, a rotor 2, a pluralityof piston 3 and a flow distribution shaft 4, wherein the stator 1 is of a cylindrical cavity structure with end covers arranged on the upper part and the lower part; the cross section of a cavity of the stator 1 is oval; the flow distribution shaft 4 is arranged in the stator 1, and the flow distribution shaft 4 is coaxial with the stator 1; the rotor 2 capable of rotating is arranged between theflow distribution shaft 4 and the cavity of the stator 1 in a sleeving mode; the upper end of the rotor 2 passes through a ball pair 6 and a transmission shaft 7 to be connected with a motor; the rotor 2 is vertically provided with a plurality of groups of plug groove groups, each plug groove group consists of a plurality of plug grooves in a circular array mode, and each plug groove is internallyprovided with a piston 3; the extending end of each piston 3 is attached to the cavity wall of the stator 1 through external force; and the two ends of the bottom of the stator 1 are separately provided with a water inlet 10 and a water outlet 11.

Description

technical field [0001] The invention relates to the field of seawater pumps, in particular to a radial multi-row vertical piston pump. Background technique [0002] The inner wall of the radial piston pump stator is elliptical, and the rotor rotates at high speed. The piston moves along the inner wall of the stator under the action of inertial force, hydraulic pressure and stator reaction force, and the volume of the working chamber formed by the piston, rotor and distribution mandrel changes. In this way, the suction hydraulic medium is realized, and the distribution mandrel makes the hydraulic medium sucked in and extruded flow in a prescribed direction. The structure of the pump is highly symmetrical, with the radial dimension of the axial piston pump and the axial dimension of the radial piston pump. The structure is very compact, with few components and high reliability. and high speed. [0003] Positive displacement pumps have the advantages of high output pressure, ...
