Description
Technical field
The present invention relates to a kind of hydraulic planger pump, belong to the hydraulic pump and hydraulic motor in Fluid-transmission and control field.
Background technology
All kinds of pluger type hydraulic pumps have approximate operation principle, i.e., in several plungers insertion cylinder bore, with pump shaft
Rotation, swash plate (or flexural pivot or eccentric shaft or multiple-action inner curved ring etc.) constraint under, plunger makees the past of opposing cylinder successively
Multiple movement, forms the swept volume of mechanical periodicity in cylinder bore, and flow is carried out by valve or valve disc.Plunger-type structure it is all kinds of
In hydraulic pump, inclined disc type valve plate distribution structure is most representative and extensive use.The structure of inclined disc type valve plate distribution hydraulic pump is special
Point is fixed using valve plate, axis structure and swash plate, and the rotation of spindle drive cylinder body drives plunger to be rotated around pump shaft and in swash plate
Constraint under it is reciprocating.Valve plate distribution has the characteristics that compact-sized, rotating speed is higher, suction capacity is good.Since there are cylinders
The sliding friction pairs such as body/valve plate, flexural pivot, ram/cylinder hole, piston shoes/swash plate, the design and manufacture difficulty of pluger type hydraulic pump
Height, cost are also higher.In addition, swash plate/piston shoes and cylinder body/valve plate friction pair bear prodigious uneven fluid pressure, friction
When secondary relative motion, the secondary pv values that rub limit the raising of operating pressure or working speed.In addition, pump bearing is in power of toppling
It is easily worn under the action of square, in turn results in the eccentric wear of valve plate.Above-mentioned reason so that the performance of pluger type hydraulic pump is not yet
It is easy to further increase.
