Description
Technical field
The utility model is related to a kind of plunger pump, especially a kind of diacytic type axial plunger pump.
Background technology
Hydraulic system suffers from very in numerous key areas such as aerospace, military issue weapons, scientific research, engineering machinery
Important application, core element of the hydraulic pump as hydraulic system, occupies an important position.Hydraulic pump include gear pump, plunger pump,
Vane pump etc., these forms pump depend on volume variation and work, and wherein the volume of plunger pump changes the reciprocal fortune by plunger
It is dynamic to realize.The inner surface of cylinder bore and the outer surface of plunger are all the peripheries that can process high fit precision, are had good
Good leakproofness, this point embodies more obvious under high pressure.
Plunger pump can be divided into two kinds of axial plunger pump and radial plunger pump, and since axial plunger pump has, rated pressure is high,
Variable is easily achieved, and range of flow is big, compact-sized, it is efficient the advantages that, therefore be widely used in various hydraulic systems
In, particularly high pressure, big flow and needs and you think the occasion of that flow-rate adjustment.Axial plunger pump can also be divided into diacytic type and
Inclined disc type two kinds, diacytic type axial plunger pump is lower relative to cam-type axial piston pump noise, but since fluid is swollen suddenly
Swollen and compression will also result in noise, so the diacytic type axial plunger pump of reasonable design is necessary.
Utility model content
The technical problems to be solved in the utility model is：Based on the above problem, a kind of diacytic type axial plunger pump is provided.
Technical solution is used by the utility model solves its technical problem：A kind of diacytic type axial plunger pump, the column
Plug pump includes pump shaft, swash plate, plunger, cylinder body and oil distribution casing, the plunger pump using shaft type driving, the swash plate, cylinder body and
Oil distribution casing is mounted on pump shaft, and cylinder body is circumferentially evenly distributed with the plunger hole that odd number is parallel to pump shaft, in each plunger hole
Equipped with plunger that can be free to slide in it, swash plate right side is close in the left side of each plunger, and the right side of cylinder body is close to match
Food tray, offers the oil suction window of kidney-shaped and oil extraction window on the oil distribution casing, the region on oil distribution casing between oil suction window and oil extraction window
Offer shock relieve vent；Ranging from 0~16 ° of the swashplate angle a, the stroke c of the plunger is 0~15mm.
Further, the cylinder body is circumferentially evenly distributed with 9 plunger holes.
Further, the pump shaft is connect with cylinder body by spline.
The beneficial effects of the utility model are：Design is scientific and reasonable for the utility model, disclosure satisfy that needs of production, knot
Simple, small, the electrodeless variable of structure, pressure are high, low noise, efficient, and manufacture is at low cost.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model.
In figure：1. pump shaft, 2. swash plates, 3. plungers, 4. cylinder bodies, 5. oil distribution casings, 6. oil suction windows, 7. oil extraction windows, 8. shock relieve vents,
9. plunger hole.
Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows the composition related with the utility model.
As shown in Figure 1, a kind of diacytic type axial plunger pump, which includes pump shaft 1, swash plate 2, plunger 3,4 and of cylinder body
Oil distribution casing 5, plunger pump are driven using shaft type, and swash plate 2, cylinder body 4 and oil distribution casing 5 are mounted on pump shaft 1, and pump shaft 1 is logical with cylinder body 4
Spline connection is crossed, cylinder body 4 is circumferentially evenly distributed with 9 plunger holes for being parallel to pump shaft 19, equipped with can be in each plunger hole 9
2 right side of swash plate is close in plunger 3 free to slide, the left side of each plunger 3 in it, and oil distribution casing is close in the right side of cylinder body 4
5, offer the oil suction window 6 of kidney-shaped and oil extraction window 7 on oil distribution casing 5, the region on oil distribution casing 5 between oil suction window 6 and oil extraction window 7 is opened
Equipped with shock relieve vent 8；Ranging from 0~16 ° of 2 inclination angle a of swash plate, the stroke c of plunger 3 is 0~15mm.
When cylinder body 4 drives plunger 3 to rotate, since 2 plane opposing cylinder of swash plate, 4 plane exists with inclination angle a, plunger is forced
3 make straight reciprocating motion in plunger hole 9, if cylinder body 4 is rotated in the range of 180 °~360 °, plunger 3 is by bottom dead centre (in figure
At d, corresponding 180 ° of positions) start constantly to stretch out, 9 volume of plunger hole constantly increases, until top dead-centre (in figure at c, corresponding 0 ° of position
Put) only.During this, plunger hole 9 is just communicated with the oil suction window of oil distribution casing 56, and fluid is inhaled into plunger hole 9, this is to inhale
Oily process；As cylinder body 4 continues to rotate, in the range of 0 °~180 °, plunger 3 is continuous by top dead-centre under the constraint of swash plate 2
Into in plunger hole 9, the volume of plunger hole 9 constantly reduces, until lower opening point stops, in this process, plunger hole 9 just with
The oil extraction window 7 of food tray 5 communicates, and fluid is discharged by oil extraction window 7, and here it is oil extraction processes.It can be seen that every turn one jump of cylinder body 4
It is each to be rotated toward this week oil suction, half cycle oil extraction is plugged with if cylinder body 4 is continuous, pump just continuously oil suction and oil extraction.On oil distribution casing 5
Region between oil suction window 6 and oil extraction window 7 offers shock relieve vent 8, can prevent fluid from expanding and compressing suddenly the noise generated
And power attenuation.
Using the above-mentioned desirable embodiment according to the utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real
The content being not limited to novel technical scope on specification, it is necessary to which its technology is determined according to right
Property range.
