Abstract
The utility model relates to a cylinder jacket with a metalloceramics coating on an internal surface for a mud pump. The utility model is formed from arranging a metalloceramics coating on the internal surface of a cylinder jacket body for a mud pump. Compared with existing cylinder jackets with a bimetal structure for mud pumps, the cylinder jacket has the advantages of simple production technology, low cost, easy guarantee for dimensional accuracy, high hardness on working surfaces, good corrosion resistance and good abrasion resistance.
Description
The utility model relates to the mud slurry pump cylinder jacket that a kind of internal surface has ceramet coating.
Mud slurry pump cylinder jacket is a kind of petroleum machinery part, requires main body to have enough strength and stiffness, internal surface has high hardness and wear resistance.For satisfying above-mentioned requirements, existing product generally is to adopt bimetal structure: skin is 45
#Cast steel; Internal layer is selected high chromium high-carbon cast iron for use, by " attire " combination.The problem of its existence is: inside and outside layer assembly precision had relatively high expectations the product processes complexity; The internal stress that " attire " combination is brought easily makes outer cracking, and quality of product is difficult to guarantee; Layer thickness＞8mm in assembly technology requires.Cause the waste of high alloy material, increased production cost of products; The internal surface wear-resisting property still remains to be improved.
The purpose of this utility model is to provide at above-mentioned problems of the prior art that a kind of production technology is simple, product cost is low, has sufficient intensity, the mud slurry pump cylinder jacket of rigidity and high wear resistance.
The technological scheme that realizes above-mentioned purpose is: provide a kind of internal surface to have the mud slurry pump cylinder jacket of ceramet coating.
The utility model has been owing to adopted the ceramet technology at the mud slurry pump cylinder jacket internal surface, compares with the mud slurry pump cylinder jacket of existing bimetal structure to have following advantage:
1, product processes is simple, and cost is low, and dimensional accuracy is easy to guarantee.
2, working surface hardness height, corrosion resistance and wear resistance are good.
Accompanying drawing is this mud slurry pump cylinder jacket master sectional view.
The utility model is described in further detail below in conjunction with accompanying drawing.
Provide as accompanying drawing, the utlity model has mud slurry pump cylinder jacket main body 1, the surface is provided with ceramet coating 2 within it.Its main body is 45
#Cast steel, wearing layer is selected chrome-base ceramic for use.Thickness of coating 0.15-0.30mm.
Claims (1)
1, a kind of internal surface has the mud slurry pump cylinder jacket of ceramet coating, comprises cylinder sleeve main body (1), it is characterized in that: be provided with ceramet coating (2) at cylinder sleeve main body (1) internal surface.
