Sand pump anti-cavitation material selection
Improve the ability of anti-cavitation flow
through parts of the material. In order to reduce cavitation on pump
parts damage, extending its life, often choose a strong anti-cavitation
properties of materials. As with cast manganese bronze, stainless steel
and alloy steel and other materials casting impeller; or coated with a
polymer or a laser sputtering surface flow components to resist
cavitation damage. In addition, over-current component surface finish to
improve its finish, but also to reduce the harm of cavitation. In
addition, pump parts and bad parts have corrosion coverage and repair
with polymeric coating (such as epoxy-based anti-cavitation resistant
materials and other thermoplastic coating, etc.), than the use of more
economical and convenient metallization which resist wear effect has
been achieved. When the parts have been eroded weldability, the
available stainless steel electrode surfacing, surfacing at the grinding
until surfacing at a slightly higher plane than the original, and then
coated with red lead at welding, grinding with a small flat and then
rubbed hard spot, after several grinding, hard spot until evenly, with
edge ruler observed surfacing at the original plane contour.
