Description
Technical field
The present invention relates 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 Aero-Space, military issue weapons, scientific research, engineering machinery
Important application, core parts of the hydraulic pump as hydraulic system, occupies critical role.Hydraulic pump include gear pump, plunger pump,
Vane pump etc., these form pumps depend on volume change and are operated, 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 sealing, 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 because axial plunger pump has, rated pressure is high,
Variable is easily achieved, and range of flow is big, compact-sized, the advantages that efficiency high, therefore is 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 because fluid is swollen suddenly
Swollen and compression will also result in noise, so diacytic type axial plunger pump reasonable in design is necessary.
The content of the invention
The technical problem to be solved in the present invention is：Based on above mentioned problem, there is provided a kind of diacytic type axial plunger pump.
The technical solution adopted for the present invention to solve the technical problems is：A kind of diacytic type axial plunger pump, the plunger pump
Including pump shaft, swash plate, plunger, cylinder body and oil distribution casing, the plunger pump is using shaft type driving, the swash plate, cylinder body and with oil
Disk is arranged on pump shaft, and cylinder body is circumferentially evenly distributed with plunger hole of the odd number parallel to pump shaft, is equipped with each plunger hole
Swash plate right side is close in plunger that can be in it slidably, the left side of each plunger, and oil distribution casing is close in the right side of cylinder body,
Offer the oil suction window and oil extraction window of kidney-shaped on the oil distribution casing, the region on oil distribution casing between oil suction window and oil extraction window offers
Shock relieve vent；The scope of the swashplate angle a is 0~16 °, and 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 connected with cylinder body by spline.
The beneficial effects of the invention are as follows：The design of the invention is scientific and reasonable, disclosure satisfy that needs of production, simple in construction,
Small volume, electrodeless variable, pressure are high, noise is low, efficiency high, and manufacturing cost is low.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
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.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As shown in figure 1, a kind of diacytic type axial plunger pump, the plunger pump includes pump shaft 1, swash plate 2, plunger 3, the and of cylinder body 4
Oil distribution casing 5, plunger pump are driven using shaft type, and swash plate 2, cylinder body 4 and oil distribution casing 5 are arranged 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 9 parallel to pump shaft 1, equipped with can be in each plunger hole 9
The right side of swash plate 2 is close in plunger 3 in it slidably, the left side of each plunger 3, and oil distribution casing is close in the right side of cylinder body 4
5, offer the oil suction window 6 and oil extraction window 7 of kidney-shaped on oil distribution casing 5, the region on oil distribution casing 5 between oil suction window 6 and oil extraction window 7 is opened
Provided with shock relieve vent 8；The inclination angle a of swash plate 2 scope is 0~16 °, and the stroke c of plunger 3 is 0~15mm.
When cylinder body 4 drives plunger 3 to rotate, because the plane of 2 plane opposing cylinder of swash plate 4 is present 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, the volume of plunger hole 9 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 6 of oil distribution casing 5, and fluid is inhaled into plunger hole 9, and 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 is communicated, and fluid is discharged by oil extraction window 7, and here it is oil extraction process.As can be seen here, every turn one jump of cylinder body 4
It is each toward being plugged with this week oil suction, half cycle oil extraction, if cylinder body 4 constantly rotates, 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 expand and compress suddenly caused by noise
And power attenuation.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
