Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of Novel swash plate type variable water hydraulic plunger displacement pump of the present invention, main shaft 3 two end supports are at housing 1 and be arranged in the end cap 2 of housing 1, swash plate 5 is supported on the front end of housing 1 inside, and and rotating body component plane contact, rotating body component and main shaft 3 pass through spline joint, and rotate around the axis of main shaft 3 together. Variable push rod 11 front ends are arranged in the ball-and-socket of swash plate 5, and rear end is arranged in the endoporus of variable piston 12. Variable piston 12 is arranged in end cap 2, and can slide axially. Control valve 15 is arranged on end cap 2, and has the cavity bottom that variable piston 12 is installed on water route and end cap 2 to be communicated with. In rotating body component, ball pivot 6 and cylinder body 7 and main shaft 3 pass through spline joint. Plunger 8 is arranged in multiple cylinders hole uniform on cylinder body. Piston shoes 9 form sphere by self ball-and-socket with plunger ball and are connected, can flexible rotating and swing. Piston shoes 9 and plunger 8, under the effect of ball pivot 6, return plate 10, are pressed in swash plate 5 surfaces. Its course of work is as follows: when the front end of main shaft 3 passes through after engine or motor driven rotary, rotating body component rotates together with main shaft 3. Wherein the plunger 8 in rotating body component is in the time that piston shoes 9 rotate with main shaft 3, and its axial location is subject to the restriction of swash plate 5 and produces axial displacement, forms periodically variable volume, and working media is periodically sucked and discharged. In the time that water hydraulic plunger displacement pump needs displacement variation, control valve 15 receives from the outside signal of telecommunication or pressure signal instruction, the pressure signal that instruction is converted into working media acts on variable piston 12 bottoms, by variable push rod 11, displacement is delivered in swash plate 5, realizes the variation of swash plate 5 pivot angles. In swash plate 5 angle change procedures, need lasting press water to supply the sliding bearing between housing 1 and swash plate 5, to reduce friction. The damping hole of press water on plunger centre bore, piston shoes centre bore, swash plate 5 enters pressure chamber, makes to produce moisture film between swash plate 5 and housing 1, realizes fluid lubrication. By reasonable disposition, can make multiple piston shoes 9 in each working cycles, there are two piston shoes to supply water to damping hole I and damping hole II (or damping hole III and damping hole IV) simultaneously, and then ensure the pressure in static pressure abutment pressure chamber, sliding bearing is normally worked.
The invention provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications; these improvements and modifications also should be considered as protection scope of the present invention, in the present embodiment not clear and definite each part all available prior art realized.
