Description
Technical field
The utility model relates to two ram cylinder structure for plunger pump.
Background technique
Axial piston pump is an important device of hydraulic system, it relies on plunger to-and-fro motion in cylinder body, the vibration-direction of plunger is parallel with the central shaft of cylinder body, thus make plunger to-and-fro motion in plunger hole produce volume-variation to realize force feed, oil suction, the advantage such as have that rated pressure is high, compact structure, efficiency are high due to plunger pump and Flow-rate adjustment is convenient, is therefore widely used in hydraulic press, engineering machinery and boats and ships.
Cylinder body is driven to rotate when axial plunger pump work by transmission shaft, make to be slidedly assemblied in cylinder body plunger hole inner plunger synchronous rotary, variable piston passes through to drive the Angulation changes of variable head and backhaul swash plate thus the adjustment realizing plunger reciprocates stroke, realize the change of oil suction and fuel delivery, oil distribution casing is installed in the bottom of cylinder body simultaneously, and oil distribution casing is used for the oil duct conversion of plunger turnover oil.Due to the kernel component that cylinder body is plunger pump, therefore working life of cylinder body and stability are directly connected to the quality of plunger pump.
Model utility content
The purpose of this utility model is the problem overcoming above-mentioned prior art, provide working life higher and stability preferably for two ram cylinder structure of plunger pump.
The purpose of this utility model is achieved through the following technical solutions:
For two ram cylinder structure of plunger pump, comprise columniform body, the center, top of described body is provided with transmission shaft mounting hole, described transmission shaft mounting hole is cylindrical counterbore, the top of described body is provided with two symmetrical plunger holes, the bottom of described body is provided with oilhole, described oilhole and described plunger hole coaxial communication, described plunger hole internal fixtion is nested with copper bush, the internal diameter of described copper bush is identical with the internal diameter of described oilhole, described copper bush sealing is connected to the bottom of described plunger hole, described copper bush and described oilhole slitless connection, the periphery of described body is provided with collar flange near top, on described flange, uniform ring is provided with multiple through hole, wherein the medial axis of two through holes and the medial axis of described plunger hole in the same plane, the top of described body is provided with annular groove near described flange.
Further, the degree of depth of described transmission shaft mounting hole is 1/1 to two/3rd of described body length.
