Abstract
The utility model discloses a novel plunger-slipper assembly which comprises a plunger, a slipper, a plunger ball head integrated with the plunger and a slipper ball socket which contains the plunger ball head and is integrated with the slipper, wherein the end surface of the slipper ball socket is provided with an oil sump. The novel plunger-slipper assembly is characterized in that the abutted surface of the plunger ball head and the slipper ball socket is positioned in the shoulder of the slipper ball socket, and an included angle alpha is formed between the abutted surface of the plunger ball head and the slipper ball socket and the cross section of the slipper ball socket. The utility model has the advantages that after the plunger-slipper assembly is finished, the acting force of the plunger ball head on the slipper ball socket is transferred outwards, the deformation of the slipper is greatly reduced, and the seal between the plunger ball head and the slipper ball socket is simultaneously improved, thereby ensuring the sufficient oil supply for static-pressure support on the end surface of the slipper and avoiding the burning of the slipper.
Description
Technical field
The utility model relates to a kind of plunger pump, relates in particular to the plunger-slippery boots assembly of plunger pump.
Background technique
The plunger piston slippery boots Shao Subcommittee-to phenomenon of A10V type plunger pump is many, and is many in the past from improvement piston shoes material and the aspect research of increase and decrease oil sump size, but effect is not very desirable.Produce through drawing piston shoes after a large amount of observation, analysis, the checking that to burn the main cause of grinding phenomenon as follows:
Piston shoes ball-and-socket and plunger ball are the spheres of two same diameter of containing, and during plunger pump work, the applying of bulb and ball-and-socket is generally in the bulb front portion, and plunger just occurs in this position to the hydraulic coupling that piston shoes transmit plunger base.The contact force of bulb shoulder and ball-and-socket is very little, even produces the gap.Piston shoes end face (with the mating face of swash plate) has oil sump, swash plate is bigger to the gap ratio of the active force of ball-and-socket to the support force and the bulb of piston shoes end face, and the intensity of piston shoes central authorities a little less than, therefore, press in the oily stroke at plunger, the plunger ball that is produced by the hydraulic coupling of plunger base deforms piston shoes to the active force of piston shoes ball-and-socket, projection is dish, cause the inboard contact stress of piston shoes end face to increase, produce Shao Subcommittee-to, this analysis conforms to the piston shoes exemplar that burning is ground;
Moreover, exist the gap easily to make the big leakage of appearance between bulb and the ball-and-socket between bulb shoulder and the ball-and-socket, cause the piston shoes oil sump to lack the fluid of importing by plunger cavity, produce Shao Subcommittee-to.
Therefore, should produce by the piston shoes of above analysis and burn the main cause of grinding phenomenon, provide a kind of plunger piston slippery boots that solves to burn the technological scheme of grinding.
The model utility content
The purpose of this utility model is at above-mentioned deficiency, provides a kind of rational in infrastructure, high working efficiency, and good sealing effect can effectively solve the piston shoes burning and grind the novel plunger-slippery boots assembly of phenomenon.
For achieving the above object, the technical solution adopted in the utility model is:
Novel plunger-slippery boots assembly, by plunger, piston shoes, with plunger be one plunger ball, contain plunger ball and with piston shoes be that the piston shoes ball-and-socket of one is formed, the end face of described piston shoes ball-and-socket is provided with oil sump, the faying surface of described plunger ball and piston shoes ball-and-socket is positioned at the shoulder of piston shoes ball-and-socket, and the faying surface of described plunger ball and piston shoes ball-and-socket and piston shoes ball-and-socket cross section form the angle of α.
Further, the angle α of the faying surface of described plunger ball and piston shoes ball-and-socket and piston shoes ball-and-socket cross section formation is 20-28 °.
Further, the central angle γ of described plunger ball and piston shoes ball-and-socket faying surface is 23-27 °, and the width b of described faying surface is 3-4mm.
The technical solution adopted in the utility model, the piston shoes ball-and-socket is repaiied type, promptly repair piston shoes ball-and-socket bottom, make the applying position of piston shoes ball-and-socket and plunger ball change to the ball-and-socket shoulder, with piston shoes ball-and-socket cross section angle be on the sphere of α, after repairing type, plunger ball moves outward the active force of piston shoes ball-and-socket, and the distortion of piston shoes greatly reduces, and the sealing of bulb and ball-and-socket simultaneously improves, the fuel feeding that piston shoes end face static pressure supports is abundant, has avoided piston shoes to burn the generation of grinding phenomenon.
If minoring in type, plunger piston slippery boots take plunger ball to repair type, it is the front portion of reconditioning plunger ball, make the applying position of plunger ball and piston shoes ball-and-socket change to the shoulder of bulb, with plunger ball cross section angle be on the sphere of α, after repairing type, plunger ball moves outward the active force of piston shoes ball-and-socket, and the distortion of piston shoes improves.But the plunger ball shoulder only overlaps when piston shoes equal zero with the axis angle of plunger with piston shoes ball-and-socket shoulder.After swash plate generation pivot angle, the axis angle of piston shoes and plunger equals the swash plate pivot angle, and the faying surface of piston shoes ball-and-socket and plunger ball becomes a central angle γ thereupon
1～γ
2The billiard table surface, the contact pressure on the faying surface is inhomogeneous.Therefore, be not used usually.And the piston shoes ball-and-socket is repaiied type, and the faying surface of ball-and-socket and bulb is the billiard table surface that a central angle is γ all the time, contact pressure is symmetrically.
The utility model has the advantages that: repair the plunger-slippery boots assembly behind the type, plunger ball moves outward the active force of piston shoes ball-and-socket, the distortion of piston shoes greatly reduces, simultaneously, the sealing of plunger ball and piston shoes ball-and-socket improves, the fuel feeding that piston shoes end face static pressure supports is abundant, has avoided piston shoes to burn the generation of grinding phenomenon.
