Abstract
The utility model provides a metal -cored not fragile, long service life's high -pressure well drilling pump piston, include metal pressure plate, buffer board, leather cup, protect root, metal -cored and cushion collar, wherein, metal -cored for falling " T " type structure, the centre is equipped with the through -hole, the leather cup cladding is in the metal -cored outside, protect between piece crossbeam and leather cup that are fixed in metal -cored " T " type, metal pressure plate and buffer board centre all are equipped with the through -hole with metal -cored the same size, and metal pressure plate compresses tightly the buffer board on the leather cup and on metal -cored, and the leather cup closely cooperates with well drilling pump cylinder sleeve inner wall, and the metal -cored outer fixed surface of " T " type crossbeam has the cushion collar. The utility model discloses the change can be dismantled to the cushion collar, has lengthened metal -cored working life greatly. The utility model discloses, work that can be long -time improves life, reduces intensity of labour, simple structure, easily loading and unloading.
Description
Technical field
This utility model is related to a kind of piston of drilling well, particularly to a kind of high pressure drilling pump piston.
Background technology
At present, the piston on drilling pump is divided into rubber and two kinds of polyurethane by material of main part.Rubber-type piston is by pressing plate, card
Spring, leather cup, mulch, metal-cored composition, this piston is mainly fitted snugly in cylinder sleeve by the high abrasion lip on leather cup
To fulfil assignment.Find in process of production its easily by mud the grains of sand scratch leather cup, mulch easily by mud impact failure,
Thus the life-span is comparatively short；And metal-cored exposed outside, the impact of mud sand grains can allow metal-cored serious wear, if metal-cored mill
Damage, then whole piston is accomplished by integral replacing, lead to production cost high.The piston of polyurethane-type is integrally to vulcanize leather cup in gold
Belong on core, this piston does not have pressing plate and jump ring, mulch and leather cup are that two kinds of materials are poured into a mould respectively and formed, operation from technique is compared
Cumbersome, inefficient, quality is also unstable；Secondly because not having pressing plate, this requires that leather cup, mulch want bonding with metal-cored
Firmly, in operation process, otherwise easily cause overall disengaging from metal-cored.
Utility model content
This utility model is directed to the defect of prior art and deficiency, provide a kind of metal-cored be hardly damaged, long service life
High pressure drilling pump piston.
The technical solution of the utility model is：A kind of high pressure drilling pump piston, including metal platen, buffer board, leather cup, shield
Root, metal-cored and cushion collar, wherein, described metal-cored for inverted " t " type structure, centre is provided with through hole；Described leather cup is coated on
Metal-cored outside；Described mulch is fixed between crossbeam and the leather cup of metal-cored inverted " t " type；In described metal platen and buffer board
Between be equipped with through hole with metal-cored formed objects, on buffer board is pressed on leather cup and is metal-cored by metal platen, leather cup
It is fitted close with cylinder sleeve of drilling pump inwall, the outer surface of metal-cored inverted " t " type crossbeam is fixed with cushion collar.
Preferably, described buffer board is high abrasion macromolecular material plate.
Preferably, described mulch is with diameter greater than metal-cored outside external diameter.
Preferably, described cushion collar is identical with metal core material, and cushion collar outer surface is through Wear-resistant Treatment.
Preferably, described cushion collar and metal-cored detachable connection.
Preferably, described metal platen and buffer board are provided with some through holes in the corresponding position with leather cup lip.
The beneficial effects of the utility model are：High pressure drilling pump piston of the present utility model, leather cup is mainly by polyurethane
Become, outside has high-wearing feature.Mulch prevents eccentric wear from causing Remedy for Piston Damage to lose efficacy.Buffer board is macromolecular material, in piston work
Leather cup and metal-cored can be protected when making, slow down metal platen because mud flow at high speed is to leather cup and metal-cored impact.Slow
Punching set is detachable, substantially prolongs metal-cored working life.This utility model, can work, raising makes for a long time
With the life-span, reduce labor intensity, structure is simply it is easy to load and unload.
Brief description
Accompanying drawing 1 is the structural representation of this utility model specific embodiment.
Specific embodiment
In order to be able to further appreciate that structure of the present utility model, feature and other purpose, in conjunction with appended preferred embodiment
Describe in detail as follows, illustrated preferred embodiment is merely to illustrate the technical solution of the utility model, and non-limiting practicality
New.
Preferred forms of the present utility model are as follows：As shown in figure 1, a kind of high pressure drilling pump piston, including metal pressure
Buffer board 2 that plate 1, high abrasion macromolecular material are made, leather cup 3, mulch 4, metal-cored 5 and cushion collar 6.Wherein, described gold
Genus core 5 is inverted " t " type structure, and centre is provided with through hole.Described leather cup 3 is coated on outside metal-cored 5.Described mulch 4 is fixed on gold
Belong between crossbeam and the leather cup 3 of core 5 inverted " t " type, mulch 4 is with diameter greater than metal-cored 5 outside external diameters.Described metal platen 1 with slow
It is equipped with the through hole with metal-cored 5 formed objects, metal platen 1 buffer board 2 is pressed on leather cup 3 and gold in the middle of punching 2
Belong on core 5.Described metal platen 1 is provided with some through holes with buffer board 2 in the corresponding position with leather cup 3 lip.Leather cup 3 and drilling pump
Inboard wall of cylinder liner is fitted close.The outer surface of metal-cored 5 inverted " t " type crossbeams is fixed with cushion collar 6.Cushion collar 6 and metal-cored 5 materials
Identical, cushion collar 6 outer surface is through Wear-resistant Treatment.Cushion collar 6 passes through screw thread and bolt detachable connection with metal-cored 5.
