Abstract
The utility model belongs to a pump accessory and particularly relates to a high-pressure pump plunger. The high-pressure pump plunger comprises a plunger body (1), a hexahedron (1-1) and a water seal contact segment (1-2), wherein the outer circumference of the water seal contact segment (1-2) at the left side of the hexahedron (1-1) of the plunger body (1) is additionally provided with a wear-resistant coating (2). As the outer circumferences of the plunger body of the high-pressure pump plunger, which is contacted with a water seal, is additionally provided with the wear-resistant coating, the abrasive resistance of the surface of the plunger is enhanced, so that the service life of the plunger is prolonged by at least three times, the maintenance down time is greatly saved, the labor strength of maintenance personnel is greatly reduced, the labor productivity is increased, and the operating cost of equipment is reduced.
Description
Technical field
The utility model belongs to pump class accessory, particularly a kind of high-pressure service pump plunger.
Background technique
In jetting machine, core component is a high-pressure plunger pump, and the working pressure of pump is 50Mpa.Plunger compares easy abrasion at work, and this mainly is that friction all the time causes between plunger and the water seal, after the plunger wear, causes the complete machine decreased performance, needs to change at once and keep in repair, and has increased surfaceman's labor intensity and cost of production.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical deficiency, provides a kind of intensity good, and abrasion resistance is high, the high-pressure service pump plunger that can increase the service life.
The technological scheme that the utility model technical solution problem adopts is: the high-pressure service pump plunger comprises plunger body, hexahedron, water seal contact-segment, is characterized in adding wear resistant coating on the excircle of water seal contact-segment in hexahedron left side of plunger body.
The beneficial effect of the utility model is: add wear resistant coating on the plunger body of high-pressure service pump plunger and the excircle that water seal contacts; Increased the wear resistance of plunger surface; Make and improve its working life more than three times; Save maintenance down time and maintenance man's labor intensity greatly, improved labour productivity, reduced the equipment operation cost.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is high-pressure service pump piston structure figure.
Among the figure, the 1-plunger body; The 1-1-hexahedron; 1-2-water seal contact-segment; The 2-wear resistant coating.
Embodiment
Embodiment, with reference to accompanying drawing 1, hexahedron 1-1 of processing in the middle of the plunger body of high-pressure service pump plunger 1 adds wear resistant coating 2 on the water seal contact-segment 1-2 excircle in hexahedron 1-1 left side, and rubbing between wear resistant coating 2 and the water seal is connected.
Claims (1)
1. a high-pressure service pump plunger comprises plunger body (1), hexahedron (1-1), water seal contact-segment (1-2), it is characterized in that adding wear resistant coating (2) on the excircle of water seal contact-segment (1-2) in hexahedron (1-1) left side of plunger body (1).
