Abstract
A three-jar slurry pump cross head which comprises a body, a transition layer and a frication layer is provided; wherein the surface of the body is of the regular or irregular concavo or convex shapes with R a 25 u m of roughness. The utility model has V letter or wave shape or screw or saw tooth surface innovated based on the surfaces of the traditional body, thus conductive to process treatment and avoid producing stress concentration to make the friction surface fall off during the operation, and what is more important is the aggrandizing of engagement degree between the body surfaces and the friction surfaces. Adopting the nickel aluminum alloy as the transition layer has simplified the production process of the combination transition layer and improved the combination intensity of the body. And with the simple structure and rational design, the combination intensity between the body layer, transition layer and the frication layer has been reinforced and the cross head falling off problem has been solved, thus improving the quality and extending the service life of the cross head, and having certain economic and social effects.
Description
Technical field
The utility model relates to a kind of crosshead, is applicable to triplex mud pump, particularly a kind of triplex mud pump crosshead.
Technical background
Crosshead is the part that connects piston and connecting rod, and the plane motion of connecting rod is converted into the to-and-fro motion of piston rod, is by body, excessive layer, and friction layer constitutes.Therefore body surface is processed as common circular shaft surface usually, when its surface is subjected to shearing force, will act directly on the circular shaft surface, causes the disengaging of body and friction layer easily, influences combining of body and friction layer.Excessively layer is meant the layer of metal of plating on body, can adopt tin, zinc, copper, aluminium, bronze, low with the adhesive strength of its body, depositing process more complicated on its material of while, wherein any link goes wrong, all influence the adhesive strength between itself and the body, in the crosshead using process, be easy to cause the situation of friction layer delamination; Friction layer generally adopts tin antimony bearing metal, cast iron, aluminum bronze, and crosshead is that friction layer and body layer break away from the course of the work for various reasons equally.Crosshead after the delamination will cause piston and cylinder wall eccentric wear, cause local contact heating, increase power consumption, and the wearing and tearing aggravation shakes disadvantages such as increase, obviously reduces the working life of crosshead.
Summary of the invention
The purpose of this utility model is to address the above problem, provide a kind of simple in structure, reasonable in design, strengthen body, excessive layer and the friction layer degree of combining closely mutually, the triplex mud pump crosshead that increases the service life.
The technical solution of the utility model is achieved in that a kind of triplex mud pump crosshead, comprises that body, transition layer and friction layer constitute, and the surface of body is regular or irregular concave-convex shape, and surface roughness is Ra25 μ m.
Described regular or irregular concave-convex shape is waveform or V font or thread-shaped or zigzag fashion.
Described transition layer material is a nickel alumin(i)um alloy.
Described friction layer material is a Babbitt.
The utility model is V font or waveform or screw thread or serrated surface with traditional body surface innovation, it is easy to carry out process treating, in use can not produce stress and concentrate and cause friction surface to come off, the more important thing is the engagement degree that has increased between body surface and the rubbing surface.Adopt nickel alumin(i)um alloy as transition layer, simplified, improved adhesive strength with body in conjunction with transition layer technology.The utility model is simple in structure, and is reasonable in design, strengthened body layer, transition layer, friction layer adhesive strength each other, solved the delamination problems of crosshead, improved the quality of crosshead, prolongs its working life, and certain economic and social benefit are arranged.
