Embodiment
For innovation and creation content, the Characteristic of the invention can be understood further, hereby exemplify following examples, be described in detail as follows:
As shown in figures 1 to 6,
A kind of multiplex radial plunger pump, comprise pump seat 1, the center of pump seat is provided with pintle mounting hole, multiple sub-pump housing 3 is in series with in a pump seat side axially, between the eccentric opening of each the sub-pump housing, there is different throw of eccentric, the right side of the sub-pump housing is also in series with pump head 6, between each the sub-pump housing 3, the sub-pump housing 3 and pump seat 1, to be sealed by seal ring 2 between pump head 6;
Pintle 14 is also installed with in pump seat.Pintle comprises axle body, axle body is provided with 3 to filler opening 15 and oil outlet 16 one to one, often pair of filler opening is all communicated with a pair flow groove 5 by oil duct 17 with oil outlet, be provided with 3 pairs of filler openings and oil outlet in the present embodiment, in figure 3, what oil duct cross section was occupied by 1/2 shade is a pair filler opening and oil outlet, and what occupy quoted by 1/3 in oil duct cross section is a pair, and what oil duct cross section was occupied by 1/4 shade is that another is right.All filler openings are symmetrical arranged with the center line of corresponding oil outlet along pintle body, and every a pair flow groove is also symmetrical arranged along the center line of pintle body.Whole filler openings and oil outlet are arranged on the left side of axle body, and whole flow grooves is arranged on the right-hand part of axle body, oil duct is arranged on the inside of axle body, offset angular between two pairs of adjacent flow grooves, the angle staggered is the oil duct center that is communicated with the two pairs of flow grooves respectively angle relative to pintle center, the angle of the flow groove that the angle that namely B-B of Fig. 4 analyses and observe represented flow groove is shown with Fig. 5 differs 60 °, and what what Fig. 5 showed showed with Fig. 6 also differs 60 °.On the length direction of flow groove, be also provided with silencing groove 4 at the two ends of flow groove.Axle body is positioned at the both sides of often pair of flow groove, is also provided with the balancing slit 18 of annular.
