Description
Technical field
The utility model relates to the cylinder body assembly parts of Variable plunger pump.
Background technique
Axial variable plunger 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 variable plunger pump works 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.
