Abstract

The invention discloses a hydraulic reciprocating driving mechanism and a hydraulic reciprocating driving pump. The hydraulic reciprocating driving mechanism comprises a piston shell, a piston and a hydraulic system, wherein the piston shell is internally provided with a hydraulic chamber; the piston is arranged in the hydraulic chamber of the piston shell and partitions the hydraulic chamber intoa first hydraulic chamber portion, a second hydraulic chamber portion and a third hydraulic chamber portion; and the hydraulic system leads low-pressure liquid into the first hydraulic chamber portion and leads high-pressure liquid into the second hydraulic chamber portion. The hydraulic system can be actuated in the modes that under a first preset working condition, the low-pressure liquid in led into the third hydraulic chamber portion, and the piston moves in a first direction; and under a second preset working condition, the high-pressure liquid is led into the third hydraulic chamber portion, and the piston moves in a second direction, wherein the second direction is opposite to the first direction. The hydraulic reciprocating driving mechanism and the hydraulic reciprocating drivingpump are compact in structure, small in size, light in weight, simple in driving mode, capable of achieving automatic reversing, small in number of quick-wear parts and low in operating cost.

Description

technical field [0001] The invention relates to the technical field of pump structure design, and relates to a hydraulic reciprocating drive mechanism and a hydraulic reciprocating drive pump. Background technique [0002] At present, in the field of reciprocating pump application, the most widely used is the three-cylinder single-acting piston reciprocating pump. figure 1 and figure 2 It is the working principle diagram of the three-cylinder single-acting piston pump widely used at present. exist figure 1 Driven by the right power source, the three pistons H of the reciprocating pump reciprocate left and right in different phases. The "T"-shaped element in the figure is a one-way valve D, and the one-way valve D will automatically open or close with the movement of the piston H. 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 al...
