Valve is arranged on assembly for plunger.Assembly for plunger contains plunger, plunger mat, spring, spring base and back-up ring, and plunger is installed on plunger mat
In, spring base is on plunger, and one end of plunger is provided with circlip groove, and back-up ring is mounted in circlip groove, and spring is on plunger, spring
One end be against on spring base, the other end of spring is against in plunger mat.In above-mentioned assembly for plunger, due on plunger
Spring base in upward spacing of plunger axis is realized by the back-up ring on plunger, when piston reciprocation moves, sweeps circle
Stress by spring base is larger, is easily damaged, shortens the service life of assembly for plunger, therefore improves the use of plunger pump
Cost.
Utility model content
Technical problem to be solved in the utility model provides a kind of plungers pump plunger assembly, the plungers pump plunger assembly
Service life is grown, so as to reduce the use cost of plunger post.
In order to solve the above technical problems, a kind of plungers pump plunger assembly of the utility model, contains plunger, plunger mat, spring
And spring base, plunger are installed in plunger mat, spring base is on plunger, and the one end of plunger is provided with annular groove, and spring is mounted in
On plunger, one end of spring is against in plunger mat, and the spring base is disk-like structure, and the spring base of the disk-like structure is provided with ring
Connected in star, the center of the spring base of disk-like structure are provided with through hole, and the through hole is outwards provided with long opening, and the width of the length opening is with leading to
The diameter in hole is identical, on the annular groove that the through-hole mounting plunger at one end that the spring base center of disk-like structure is provided with is provided with, spring
In the annular groove that the spring base that the other end is against disk-like structure is provided with.
The external diameter for the annular groove that the spring base of the disk-like structure is provided with is 1.05 times of the spring outer diameter.
The spring base of the disk-like structure is one time punching molded by steel plate.
The width for the annular groove that the plunger at one end portion is provided with is to be described by the one time punching molded disk-like structure of steel plate
Three times of the thickness of spring base.
The thickness of the spring base of the disk-like structure one time punching molded by steel plate is that the plunger at one end portion is provided with ring
/ 3rd of shape well width.
The spring is spiral compression spring.
One end of the plunger is contour body structure.
In above-mentioned plungers pump plunger assembly, because spring base is that disk-like structure which is provided with annular groove, and center is set
There is through hole, through hole opens outward length opening, this not only enables the annular that spring base is easily provided with mounted in plunger at one end portion
On groove, while also make spring base in axial direction by spacing, and one end of spring is against what the spring base of disk-like structure was provided with
In annular groove, make spring in radial direction by spacing.Compared with prior art, back-up ring is eliminated, is overcome when piston reciprocation is transported
Sweep that circle is larger by spring base stress when dynamic, caused by damage, shorten the deficiency of assembly for plunger service life, therefore prolong significantly
The service life of assembly for plunger is grown, so as to reduce the use cost of plunger pump.

Embodiment
In Fig. 1, the utility model discloses a kind of plungers pump plunger assembly, contains plunger 6, plunger mat 1, spring 2 and bullet
Spring abutment 3.Plunger 6 is installed in plunger mat 1, and for spring base 3 on plunger 6, the one end of plunger 6 is provided with annular groove 5, spring 2
On plunger 6, one end of spring 2 is against in plunger mat 1, and the spring base 3 is disk-like structure, the spring base of the disk-like structure
3 are provided with annular groove 7, and the center of the spring base 3 of disk-like structure is provided with through hole 8, and the through hole 8 is outwards provided with long opening 9, the length
The width of opening 9 is identical with the diameter of through hole 8.The through hole 8 that the center of spring base 3 of disk-like structure is provided with inserts the one end of plunger 6 and set
On some annular grooves 5, in the annular groove 7 that spring base 3 that the other end of spring 2 is against disk-like structure is provided with.
Radial direction in the annular groove 7 being provided with for the ease of the other end of spring 2 on the spring base 3 of disk-like structure is determined
Position, the external diameter for the annular groove 7 that the spring base 3 of the disk-like structure is provided with are 1.05 times of the external diameter of spring 2.
To reduce production cost, the spring base 1 of the disk-like structure is one time punching molded by steel plate.
It is inserted into for the ease of the spring base 3 of disk-like structure in the annular groove 5 that the one end of plunger 6 is provided with, the plunger 6
The width for the annular groove 7 that one end is provided with is the thickness of the spring base 3 by the one time punching molded disk-like structure of steel plate
Three times.
In order to reduce cost, the spring 3 is spiral compression spring.
In order to reduce the frictional force between tilting frame assembly and plunger 6, one end of the plunger 6 is contour body structure 4.
In above-mentioned plungers pump plunger assembly, because spring base 3 is that disk-like structure which is provided with annular groove 7, and center
Provided with through hole 8, the opens outward of through hole 8 length opening 9, this not only enables spring base 3 be easily provided with mounted in the one end of plunger 6
Annular groove on 5, while also make spring base 3 in axial direction by spacing, and one end of spring 2 is against the spring base of disk-like structure
7 in 3 annular grooves being provided with, make spring 2 in radial direction by spacing.Compared with prior art, back-up ring is eliminated, overcomes and works as
Piston reciprocation sweeps circle when moving larger by the stress of spring base 3, caused by damage, shorten assembly for plunger service life not
Foot, therefore the service life of assembly for plunger is substantially prolongs, so as to reduce the use cost of plunger pump.
