Description

technical field [0001] The invention belongs to the technical field of reciprocating pumps, and in particular relates to a reciprocating plunger pump. Background technique [0002] At present, in the field of reciprocating pump applications, the most widely used is the three-cylinder single-acting piston reciprocating pump. Driven by the power source, the three pistons of the reciprocating pump reciprocate left and right in different phases. The three-cylinder single-acting reciprocating pump of this structure mostly adopts the motion principle of the crankshaft and connecting rod, and cannot be driven by hydraulic pressure, let alone automatically reversing. Its mechanical structure is complex, bulky, low in mechanical efficiency, and its moving parts are easy to wear and maintenance high cost. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide a reciprocating plunger pump, which not only has...
