Beneficial effect of the present invention
(1) the present invention has all advantages that " a kind of plunger pump of simple structure " compared with more traditional plunger pumps of patented technology such as " combined simple plunger pumps ", removed part rapid wear assembly, simplify the structure, make to install more convenient, also obviously increased axial piston pump oil pump capacity, strengthened oil pressure, make plunger pump reaching under identical oil pump capacity, oil pressure parameter prerequisite, reduced power consumption.
(2) the present invention controls the reciprocal operation of plunger valve rod with two inclined plate, has replaced with easily damaged parts spring and has controlled the back and forth structure of operation of plunger valve rod, has not only improved the Safety performance of plunger pump, and plunger pump can be realized run up, bring into play larger usefulness; The noise that has simultaneously reduced machine, has extended working life.
Accompanying drawing explanation
Accompanying drawing 1 is list group plunger valve group's of the present invention longitudinal profile structural representation;
Accompanying drawing 2 is the longitudinal profile structural representation that the present invention organizes plunger valve group more.
Embodiment
As shown in Figure 1, 2,
The plunger valve group 1 that the present invention arranges in the pump housing, centered by the power input shaft 2 of pump housing power equipment (as motor, diesel engine, petrol engine etc.), is provided with and in the plunger valve 3(Fig. 1 laying in the orientation such as a plurality of, only represents corresponding a pair of two).Each plunger valve is mainly comprised of valve rod 31 and valve body 32.Valve body wall is provided with oil extraction inclined hole 33, and oil extraction inclined hole connects the oil pocket 5 that oil drain passage leads to the pump housing, and oil pocket leads to hydraulic equipment (not shown) by total oil exit pipe 4; The bottom of valve body is provided with oil-sucking hole 34.Oil extraction inclined hole lower end is provided with boss 331 with the place of communicating, valve body chamber, is placed with oil drainage hole steel ball 332 on boss; Oil-sucking hole 34 is provided with concave station 341, is placed with oil-sucking hole steel ball 342 on concave station.
The present invention and power input shaft 2 are connected with large footpath swash plate 7, path swash plate 8.The inclined-plane 71 of large footpath swash plate 7 downward, is pressed in during rotation on the stem head of each plunger valve.The inclined-plane 81 of path swash plate 8, towards top, plays a supportive role to disk 9 during rotation, and disk 9 imposes on the different pressures of each plunger stem head during with large footpath swash plate 7 rotation, promote and each plunger valve rod that declines, with complete each plunger valve body into and out of oily operation.
Again shown in Fig. 2, for the present invention establishes the embodiments that organize plunger valve groups more.Plunger valve group 1 in figure is three groups, arranges successively centered by pump housing power input shaft 2, is provided with connecting cylinder 6 between each group, will organize plunger valve group more and connect into the whole pump housing.Connecting cylinder is provided with the filler opening 61 being connected with pump externally mounted fuel tank, and it is positioned at the bottom of the one group of plunger valve group valve body in below and has pump fuel tank 10, and communicates with pump externally mounted fuel tank (not shown) by the filler opening 61 of connecting cylinder.
Assembly bearing involved in the present invention does not all represent in the drawings.
Below in conjunction with accompanying drawing, brief description working procedure of the present invention:
The power input shaft 2 of two inclined plate structure plunger pump of the present invention, drives the large footpath swash plate 7, the path swash plate 8 that are connected with axle to rotate.As Fig. 1, when the inclined-plane minimum point of large footpath swash plate 7 is pressed on a certain plunger stem head, this plunger valve rod is operation downwards, and drives this position of disk 9 in low level, and another plunger valve rod of the opposite location claiming with this plunger valve pole pair is in uplink state; Meanwhile, due to the effect of the peak on path swash plate inclined-plane 81, make disk 9 drive the plunger at these places up to move, another plunger valve rod of the opposite location claiming with this plunger valve pole pair is in downstream state.Oblique contrary because of path swash plate 8 and large footpath swash plate 7, therefore when path swash plate 8 rotates with rotatingshaft, in support disk 9, dodge out again the space of large footpath swash plate 7 rotations.With in like manner upper, remaining each plunger valve rod is by between the up or decline of transmitting in linearity.When plunger valve valve rod moves up, oil-sucking hole steel ball 342 is picked up, and oil-sucking hole sucks fluid; When plunger valve valve rod is during to bottom offset, oil-sucking hole steel ball 342 is adjacent in oil suction aperture, and the fluid in valve pocket is the communications centre oily inclined hole steel ball 332 that begins to rehearse, and the fluid in valve pocket is discharged from oil extraction inclined hole 33, enters pump housing oil pocket and oil outlet tube.Because boss or concave station add, be provided with chamfering man-hour, thereby steel ball drops on oil drainage hole or oil-sucking hole and all can have good sealability.The present invention, by each group plunger valve group's plunger valve rod to-and-fro motion again and again, makes the oil outlet of plunger pump have high pressure oil continuously to export engineering hydraulic equipment to from oil outlet tube, thereby reaches the goal of the invention of expection.
