Multiplex radial plunger pump

Abstract

The invention relates to a multiplex radial plunger pump which comprises a pump base. The center of the pump base is provided with a flow distribution shaft installation hole; one side surface in the axial direction of the pump base is connected in series with a plurality of son pump bodies; eccentric holes of the son pump bodies have different eccentric distances; the right side of the son pump bodies is connected in series with a pump head; the son pump bodies, the son pump bodies and the pump base as well as the son pump bodies and the pump head are sealed through seal rings respectively; a flow distribution shaft passes through the pump base; the flow distribution shaft comprises a shaft body; the shaft body is provided with a plurality of pairs of oil inlets and oil outlets; each group of oil inlet and oil outlet are communicated with one pair of flow distribution grooves through an oil passage; positions of the flow distribution grooves are corresponding to the eccentric directions of the son pump bodies respectively; each son pump body is internally provided with a bearing; the middle portion of the flow distribution shaft is sleeved with a cylinder body in a circumferential rotation manner; the right end of the cylinder body is connected with a transmission shaft; the transmission shaft is arranged in the pump head through a rolling bearing; the cylinder body is internally provided with plungers in a radial sliding manner; and the outer ends of the plungers push against inner rings of the bearings respectively. The advantage of the multiplex radial plunger pump is that a multiple independent radial plunger pump integrated structure can be realized.

Description

technical field [0001] The invention belongs to the technical field of plunger pumps, and in particular relates to a multi-connected radial plunger pump. Background technique [0002] At present, radial piston pumps all use valve flow distribution and plunger combination to achieve the purpose of a pump having multiple independent pressure oil outlets and supplying oil to different systems. Difficult, when adjusting the displacement, it is difficult to adjust the displacement arbitrarily due to the influence of the plunger. However, due to the impact of the structure, the shaft distribution radial piston pump cannot use the combination of the distribution shaft and the plunger to achieve the purpose of multiple pressure oil outlets. Contents of the invention [0003] In order to solve the technical problems in the known technology, the invention provides a flow distribution shaft for a multi-connected radial plunger pump, and the plunger pump can realize the integrated st...

Difficult, when adjusting the displacement, it is difficult to adjust any displacement due to the influence of the plunger

However, due to the influence of the structure, the shaft distribution radial piston pump cannot use the combination of the distribution shaft and the plunger to achieve the purpose of multiple pressure oil outlets.
