Abstract
The utility model relates to a hydraulic pump, in particular to a novel hydraulic plunger pump, and aims at providing the novel hydraulic plunger pump of which a moving member is arranged at the outside, a fixed member is arranged at the inside, and the structure is simple. The novel hydraulic plunger pump consists of a sealing disk 1, screws 2, an oil drainage port 3, an oil extrusion valve 4, an oil suction valve 5, an oil inlet port 6, an oil inlet-outlet hole 7, a bracket 8, an inner curve rotating wheel 9, a cylinder body 10, pistons 11, roller wheels 12 and springs 13. The cardinal principle lies in that: the rotation of the inner curve rotating wheel 9 enables the four pistons 11 to synchronously reciprocate in the cylinder body 10; and oil extrusion and suction are realized by changing the volume of a space in the cylinder body so as to apply work externally. Compared with the prior art, the novel hydraulic plunger pump has the advantages of reasonable design, simple structure, large output power and high working efficiency.
Description
Technical field
The utility model relates to a kind of oil hydraulic pump, especially a kind of novel hydraulic plunger pump.
Background technique
For Electric Traction and mechanical transmission, it is big that hydraulic transmission has ouput force, in light weight, and inertia is little, and speed governing is convenient and be easy to advantage such as control, thereby is widely used in engineering machinery, on the equipment such as building machinery and lathe.Oil hydraulic pump then is the dynamical element of hydraulic system, and its effect is the pressure energy that the mechanical energy of prime mover is converted to liquid, has both referred to the oil pump in the hydraulic system, and it provides power to whole hydraulic system.The structural type of oil hydraulic pump generally has gear pump, vane pump and plunger pump, plunger pump is to cause the variation of sealed volume to realize oil suction and the oil hydraulic pump of pressing oil by plunger is reciprocating in cylinder body, it is different with moving direction that existing plunger pump is pressed the arrangement of plunger, can be divided into radial plunger pump and axial piston pump two big classes, generally be divided into single plunger and double-plunger again by plunger quantity, and on the structure all be movement parts interior, fixed block outside, so complex structure.
Summary of the invention
The purpose of this utility model is to provide a kind of movement parts outside, and fixed block is interior, a kind of novel hydraulic plunger pump simple in structure.
A kind of novel hydraulic plunger pump of the utility model, form by seal disc 1, screw 2, oil drain out 3, pressure fuel tap 4, oil sucting valve 5, filler opening 6, turnover oilhole 7, support 8, inner curve moving runner 9, cylinder body 10, piston 11, roller 12, spring 13, it is characterized in that, perforate also is enclosed within cylinder body 10 two ends respectively in the middle of the discoidal seal disc 1, is fixed on inner curve moving runner 9 both sides by equally distributed screw 2; Cylinder body 10 is cross, the middle part is the cylindrical body of a hollow, outside four hollow circular cylinders bottom is connected with its side and evenly distributes, four hollow circular cylinder the other ends are connected and fixed by four loop, the part that seal disc 1 is stretched out at cylinder body 10 middle parts connects support 8, and in one side central authorities turnover oilhole 7 is set; Turnover oilhole 7 connects pressure fuel tap 4 and oil drain out 3 by pipeline one end of T font, and the other end connects oil sucting valve 5 and filler opening 6, presses fuel tap 4, oil sucting valve 5 to be one-way valve; The piston 11 that four tops are connected with roller 12 respectively splits on cylinder body 10 in four equally distributed hollow circular cylinders; Spring 13 the other ends that piston 11 bottoms connect are fixed on the inwall of cylinder body 10 central authorities; Roller 12 remains with the inner ring of inner curve moving runner 9 and contacts.
A kind of novel hydraulic plunger pump of the utility model, its cardinal principle is to make four pistons 11 move reciprocatingly synchronously in cylinder body 10 by the rotation of inner curve moving runner 9, realize extrusion and suction by the volume that changes space in the cylinder body to oil, thus externally acting.Compared to existing technology, the beneficial effects of the utility model are that reasonable in design, simple in structure, output power is big, high working efficiency.

Among the figure: seal disc 1, screw 2, oil drain out 3, pressure fuel tap 4, oil sucting valve 5, filler opening 6, turnover oilhole 7, support 8, inner curve moving runner 9, cylinder body 10, piston 11, roller 12, spring 13
Embodiment
Example 1
A kind of novel hydraulic plunger pump of the utility model, comprise inner curve moving runner 9, cylinder body 10, be fixed on the discoidal seal disc 1 on the inner curve moving runner 9, four screws 2 of fixing seal dish 1, be connected cylinder body 10 middle parts and stretch out the support 8 of the part of seal disc 1, turnover oilhole 7 in the central is set, be connected the pressure fuel tap 4 and the oil drain out 3 of T tube road one end of connecting turnover oilhole 7, be connected the oil sucting valve 5 of the other end and filler opening 6, split on cylinder body 10 11, four in piston in four equally distributed hollow circular cylinders and be connected the roller 12 on piston 11 tops; Be connected the spring 13 of piston 11 bottoms.When reality is used, the utility model is supported by support 8, keeps the airtight relatively of its inside by screw 2 fixing seal discs 1, simultaneously owing to press fuel tap 4, oil sucting valve 5 to be one-way valve, then can finish suction and extrusion, guarantee cylinder body 10 inner oil mass supplies oil by turnover oilhole 7; Inner curve moving runner 9 is begun to rotate by motor or internal combustion engine drive, make piston 11 in cylinder body 10, do synchronous to-and-fro motion by roller 12, when inner curve moving runner 9 and piston 11 move to state shown in Figure 1, it is maximum that cylinder body 10 inner spaces reach, both reached the oil suction maximum value, NextState begins to press oil, externally acting, and spring 13 begins to be compressed, when state shown in Figure 2, it is minimum that cylinder body 10 inner spaces reach, and both reached and pressed oily maximum value, and NextState begins oil suction, spring 13 begins to stretch, so shuttling movement continues externally acting, reaches purpose of design.
