Description
Technical field
The present invention relates to a kind of plungers pump plunger regulation of mental activities structure.
Background technology
Reciprocating pump is a kind of application engineering goods widely, plays an important role at industry industry-by-industry.
With reference to Fig. 1, one of main failure forms of reciprocating pump is, when plunger 7 ' and filler 8 ' work, eccentric wear occurs, and heating is serious,
Quick abrasion, reveals serious, and the life-span is short, has a strong impact on the reliability of reciprocating pump.
Conventional reciprocating plunger pump power end with the connecting mode of fluid end is: the intermediate bar extension bar 1 ' of power end and fluid power
The plunger 7 ' of end is coupled by screw thread, clip form, sees as shown in Figure 1 and Figure 2, central link part comprise a bar extension bar 1 ',
Snap ring 4 ', pad 5 ', clamp nut 6 ', plunger 7 ', filler 8 ', fairlead 9 ', sealed letter body 10 ', retaining ring 12 ' etc..Middle
Bar extension bar 1 ' is directly connected with planar end surface with plunger 7 ', and plunger 7 ' is arranged in the plunger cavity 11 ' of intermediate bar extension bar 1 '.Back and forth
Under the driving of mechanism, intermediate bar extension bar 1 ' drives plunger 7 ' reciprocating in filler 8 ', fairlead 9 '.Due to power end,
All there is mismachining tolerance in each movement parts of fluid end, as intermediate bar extension bar 1 ' contacts with plunger 7 ' error of perpendicularity of end face,
Intermediate bar extension bar 1 ', plunger 7 ' is made to require to be difficult to ensure that with each axiality, the depth of parallelism of fairlead 9 '.When plunger 7 ' is with middle
Bar extension bar 1 ' couple after all of cumulative error concentrate on plunger 7 ' with on the planar end surface of intermediate bar extension bar 1 ', cause plunger 7 ' with
Intermediate bar extension bar 1 ' is not on straight line, and produces eccentric wear between filler 8 ', fairlead 9 ', and heating is serious, promote plunger 7 ', filler
8 ' accelerated wear tests, service life are short, thus affect the reliability of reciprocating pump, and efficiency is low.
Summary of the invention
The technical problem to be solved is to provide a kind of plunger to put down with intermediate bar extension bar for above-mentioned prior art
Row degree is adjusted, and the plungers pump plunger regulation of mental activities structure of eccentric wear occurs when can be prevented effectively from plunger and filler working in reciprocating mode.
The present invention solves the technical scheme that above-mentioned technical problem used: a kind of plungers pump plunger regulation of mental activities structure, including
It is arranged on the middle brace rod being connected with reciprocating drive mechanism of power end, is arranged on the plunger of fluid end, middle brace rod
End face is provided with plunger cavity, it is characterised in that: the end of described plunger is connected between the end of connecting rod by sphere slide assemblies
Portion, wherein sphere slide assemblies includes:
Adjustment block, is arranged on the bottom of plunger cavity, and this adjustment block has hemispherical groove；
The end that described plunger is connected with middle brace rod also is provided with hemispherical groove；
Spheroid, the half of this spheroid is positioned at the hemispherical groove of adjustment block, and second half of this spheroid is positioned at the half of plunger
In ball recess；
The outer cover of plunger and middle brace rod connecting portion is provided with clamp nut, for by plunger and sphere slide assemblies
It is connected between the end of connecting rod.
As improvement, the aperture of described plunger cavity, more than the external diameter of adjustment block, which forms adjustment block at intermediate bar
Can be freely movable in endoporus, play regulation of mental activities effect.Its monolateral gap for by installation reach automatic aligning ensure plunger with in
Between the depth of parallelism of bar.
Improving, the bottom of described plunger cavity is plane again, and one end of described adjustment block is plane, and other end is offered
Stating hemispherical groove, the plane of adjustment block can be the most movable in the baseplane of plunger cavity.
Improving, be provided with snap ring inside described clamp nut, this snap ring is Hough snap ring, described plunger and middle brace rod
The end outer wall connected is provided with cannelure, and Hough snap ring is installed in this cannelure, described Hough snap ring and clamp nut and post
Plug compact siro spinning technology.
Improving, the outer wall of middle brace rod is provided with external screw thread again, and described clamp nut is socketed in the outer wall of middle brace rod
On.
Improving, described clamp nut outer wall is cased with retaining ring, and fixes with circlip for shaft again.
Improve again, the end diameter that the aperture of described clamp nut is connected with middle brace rod more than plunger, in being conducive to
Between bar couple with the centering type of plunger.
Compared with prior art, it is an advantage of the current invention that: sliding by setting up sphere between plunger and middle brace rod
Dynamic assembly, spheroid can be freely rotatable in the hemispherical groove of adjustment block with the hemispherical groove of plunger end, the most just can disappear
Except plunger and intermediate bar connect the error of perpendicularity of end, and then can ensure that the positioning datum of plunger and fairlead, make plunger be placed in
Fairlead and filler center, effectively eliminate plunger and contact the error of perpendicularity of end face with intermediate bar, reaches plunger with middle
The depth of parallelism of bar, prevents both not parallel and produces plunger eccentric wear, heating, reduces efficiency, shortens plunger, fairlead and filler
Service life.
