Abstract
The present invention relates to a kind of swash plate for axial plunger pump.Its object is to reducing hydraulic shock, reducing noise and reducing pressure fluctuation, to improve the life and reliability of plunger pump.Described swash plate includes disk body, left rotary shaft and right spindle；Left rotary shaft and right spindle are arranged at the edge of disk body；Disk body is circle ring disk, i.e. disc centre is provided with round tube hole；The upper disk surface of disk body is working face；There is eccentric throw in the center of circle ring disk, the eccentric throw is 0.5mm~3mm relative to the axis of left rotary shaft and right spindle.The harm that pump negative moment is brought is eliminated, reduces and eliminates hydraulic pressure impact of flow distribution and noise, improve the effect of the discharge uniformity of pump, extend the service life of plunger pump.
Description
Technical field
The invention belongs to fuel oil/hydraulic oil axial plunger pump designing technique, it is related to the swash plate for axial plunger pump
Improve.
Background technology
Aviation plunger pump, mainly there are Aviation Fuel plunger pump and aircraft fluid (lubricating oil) plunger pump.Aviation Fuel post
Plug pump is mainly used in fuel oil main pump and vector spout oil sources pump.Aircraft fluid (lubricating oil) plunger pump is mainly used in aircraft hydraulic
Control system.
Civilian plunger pump is mainly used in engineering machinery and various hydraulic systems, is power source.
The subject matter that China's plunger pump presently, there are is that pressure is low, short life, and reliability is low, and there is an urgent need to long-life post
Fill in pump.And the reason for plunger pump short life, is related to many aspects.Wherein hydraulic shock, noise and pressure fluctuation are main cause greatly
One of.
A kind of structure of current swash plate for axial plunger pump has following two aspects referring to Fig. 1, its shortcoming：First,
In the presence of a negative moment, cause pump discharge pressure pulsation larger.2nd, hydraulic shock is larger.
The content of the invention
Goal of the invention：The present invention discloses a kind of swash plate for axial plunger pump.Its object is to reduce hydraulic shock, drop
Low noise and reduction pressure fluctuation, to improve the life and reliability of plunger pump.
The technical scheme is that：A kind of swash plate for axial plunger pump, described swash plate include disk body, left rotary shaft
And right spindle；Left rotary shaft and right spindle are arranged at the edge of disk body；
Disk body is circle ring disk, i.e. disc centre is provided with round tube hole；The upper disk surface of disk body is working face；
Eccentric throw be present relative to the axis of left rotary shaft and right spindle in the center of circle ring disk, the eccentric throw be 0.5mm~
3mm。
Further, working face is inclined-plane, and working face and axis are into 1.5 °~4 ° of angle.
Further, the working face from left-hand rotation shaft position turn right axle position tilt.
Further, extend to form swing arm in the lower card of disk body.
Invention effect
It is an advantage of the invention that：A kind of improved swash plate for axial plunger pump is proposed, eliminates pump negative moment band
The harm come, reduce with eliminating hydraulic pressure impact of flow distribution and noise, improve the effect of the discharge uniformity of pump, extend plunger pump
Service life.
Brief description of the drawings
Fig. 1 is the structural representation of the axial plunger pump swash plate of prior art；
Fig. 2 is the structural representation of the axial plunger pump swash plate of the present invention；
Wherein：1- left rotary shafts, 2- right spindles, 3- swing arms, 4- disk bodies.
Embodiment
The present invention is described in further details below.A kind of swash plate for axial plunger pump is shown in Fig. 2,
A kind of swash plate for axial plunger pump is provided, described swash plate includes disk body, left rotary shaft and right spindle；Left rotary shaft
The edge of disk body is arranged at right spindle；
Disk body is circle ring disk, i.e. disc centre is provided with round tube hole；The upper disk surface of disk body is working face；
Eccentric throw be present relative to the axis of left rotary shaft and right spindle in the center of circle ring disk, the eccentric throw be 0.5mm~
3mm。
Further, working face is inclined-plane, and working face and axis are into 1.5 °~4 ° of angle.
Further, the working face from left-hand rotation shaft position turn right axle position tilt.
Further, extend to form swing arm in the lower card of disk body.
The present invention operation principle be：Swash plate rotating shaft eccentric throw is that swash plate rotating shaft biases certain distance to specific direction.Pressure
Contracting angle is the angle between swash plate working face and swash plate rotating shaft.In real work, swash plate rotating shaft eccentric throw can adjust plunger
Chamber hydraulic coupling eliminates the negative moment of pump, and then reduce the pressure fluctuation of plunger pump to the opplied moment of swash plate rotating shaft.Compression angle can
To effectively reduce and eliminate hydraulic pressure impact of flow distribution and noise, improve the effect of the discharge uniformity of pump, while compression angle is deposited
In the effect that pump can be made to possess safety valve, pump will not be allowed to reach zero degree, certain flow be present, meet pump self-lubrication
It is required that improve the security of pump.
