Inclined disc type valve flow distribution high pressure pure water plunger pump

The utility model relates to a pump, to be specific an inclined disc type valve flow distribution high pressure pure water plunger pump mainly constituted by a main shaft, an inclined disc-sliding shoes mechanism, a plunger-cylinder mechanism, a valve flow distribution mechanism. The main shaft can drive the cylinder and the valve flow distribution mechanism together to rotate through a spline, besides, the plunger rotates with the cylinder together, moves back and forth relatively to the cylinder, and drive the sliding shoes connected with the plunger to slide on the inclined disc surface. A suction valve, extrusion valve can be connected or disconnected with a plunger cavity successively to realize the suction and extrusion function of the pump. The inclined disc of the utility model can not rotate, thereby the swing of the cylinder caused by the unbalanced quality of rotating inclined disc can be prevented. A sliding bearing on the main shaft, a big sliding bearing on the outer periphery of the cylinder and a sliding bearing on the tail of the cylinder can be used to relieve the swing of the pump caused by the flexible bending of the main shaft and the swing of the cylinder, thereby the plunger pump can function smoothly. In the utility model, the flow distribution valve can be used to replace the flow distribution disc, key friction pairs can be reduced, and the high pressure of the inclined disc type pure water plunger pump can be realized.
