Abstract
The utility model provides a high-pressure well drilling pump piston which is composed of a metal pressing plate, a buffering plate, a leather cup, a mulch and a metal core. The metal core is of a structure in the shape of a Chinese character '+-',a through hole is arranged in the middle of the metal core, the leather cup is coated on the outer side of the metal core, the mulch is fixed between a bottom platform of the metal core and the leather cup, the pressing plate tightly presses the buffering plate on the leather cup, and the leather cup is closely matched with the inner wall of a cylinder sleeve of a well drilling pump, so that leakage of slurry during operation can be avoided while needed circulating pressure is guaranteed. The high-pressure well drilling pump piston is simple in structure.
Description
Technical field
The utility model relates to a kind of assist, is the piston that a kind of drilling well is used specifically.
Background technique
At present, the piston on drilling pump is divided into two kinds of rubber and polyurethane by material of main part.Rubber-type piston is by pressing plate, jump ring, leather cup, mulch, metal-cored composition, and this piston is mainly to be fitted snugly in cylinder sleeve and fulfiled assignment by the high abrasion lip on leather cup.Find that in process of production it is easily by stroke leather cup of the grains of sand in mud, mulch is easily by mud impact failure, thereby the life-span is shorter.The piston of polyurethane-type be by the whole sulfuration of leather cup on metal-cored, 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 and formed respectively, from the technique trouble of making comparisons of going out to drill, efficiency is not high, quality is also unstable; Secondly owing to there is no pressing plate, this just requires leather cup, mulch and metal-cored bonding firm, otherwise in operation process, easily causes whole from metal-cored disengaging.
Model utility content
The purpose of this utility model is that existing wellbore pump piston is heat-resisting, wear resistance is poor in order to overcome, the shortcoming such as can not effectively play a role in drilling process, and the high pressure drilling pump piston providing, this piston is not only heat-resisting, wear-resisting, withstand voltage, and can work for a long time, for later stage production brings convenience.
The utility model solves the technological scheme that its technical problem adopts: high pressure drilling pump piston, comprise metal platen, cushion plate, leather cup, mulch and metal-cored, and metal-cored employing " soil " font structure, centre is through hole; Leather cup is coated on metal-cored outside; Mulch is fixed between metal-cored base frame and leather cup; Metal platen is pressed on cushion plate on leather cup, and leather cup and cylinder sleeve of drilling pump inwall closely cooperate.
On described metal platen and cushion plate all with through hole; Cushion plate is that macromolecular material is made.
Described leather cup is made by polyurethane, and external diameter is than metal-cored and metal platen is bigger.
Described mulch is " L " type, is slightly larger than metal-cored outside external diameter, by the macromolecular material of high abrasion, is made.
Leather cup is mainly made by polyurethane, and outside has high wear resistance.Mulch prevents that eccentric wear from causing Remedy for Piston Damage to lose efficacy.Cushion plate is macromolecular material, when pistons work, can protect leather cup, slows down metal platen due to the impact of mud flow at high speed to leather cup.
The beneficial effects of the utility model are, can work for a long time, improve working life, reduce labor intensity, simple in structure, are easy to handling.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
In figure: 1 is metal platen, 2 is cushion plate, and 3 is leather cup, and 4 is mulch, and 5 is metal-cored.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
In Fig. 1, high pressure drilling pump piston, comprises that metal platen 1, cushion plate 2, leather cup 3, mulch 4 and metal-cored 5, metal-cored 5 adopt " soil " font structure, and centre is through hole; Leather cup 3 is coated on metal-cored 5 outsides; Mulch 4 is fixed between metal-cored 5 base frames and leather cup 3; Metal platen 1 is pressed on cushion plate 2 on leather cup 3, and leather cup 3 closely cooperates with cylinder sleeve of drilling pump inwall.
On described metal platen 1 and cushion plate 2 all with through hole; Cushion plate 2 is made for macromolecular material.
Described leather cup 3 is made by polyurethane, external diameter than metal-cored 5 and metal platen 1 bigger.
Mud enters in the groove of leather cup 3 by the through hole on pressing plate 1 and cushion plate 2, is that the lip of leather cup 3 is because rising and the cylinder sleeve of pressure closely cooperate.
