Abstract

The invention discloses an embedded type low-flow-resistance plunger pump cylinder structure which can reduce resistance of hydraulic medium fluid, improves self-sucking performance, facilitates increasing rotation speed and improves flow. The embedded type low-flow-resistance plunger pump cylinder structure comprises a cylinder body which can reduce processing processes and reduces production cost, wherein a plunger pump hole and a waist-shaped hole are distributed in the cylinder body; the plunger pump hole mutually communicates with the waist-shaped hole; the bottom end in the plunger pumphole is embedded with an embedded type rectifying block; a runner which communicates with the waist-shaped hole for enabling the hydraulic medium flow to be smoother is distributed in the embedded type rectifying block; and the runner is a smooth curved surface or a surface set which consists of a plurality of discrete planes or curved surfaces.

Description

technical field [0001] The invention relates to an embedded low-flow-resistance plunger pump cylinder body structure. Background technique [0002] When the axial piston pump is working, the cylinder rotates, and the plunger in the cylinder hole reciprocates along the axis, such as figure 1 As shown, the suction and discharge of the hydraulic medium are completed after the waist hole 2 communicates with the plunger hole 3 in the cylinder. The bottom of the plunger hole 3 is circular or tapered by the machining tool, and the waist hole 2 is connected to the bottom shape to form a machined edge 1, which hinders the flow of the hydraulic medium when sucking / discharging the hydraulic medium. Flow, the self-priming performance of the plunger pump is affected, which is not conducive to increasing the speed and increasing the flow. At the same time, the cylinder bore is relatively deep, and the processing of complex shapes at the bottom of the cylinder bore is limited by machine ...
