Abstract
The invention discloses a treatment process for improving damage of a fluid medium to a mortar pump impeller, which relates to the technical field of impeller processing, and specifically comprises the following steps: 1) obtaining a layered zirconium phosphate precursor by using zirconium oxychloride, phosphoric acid and sodium fluoride; 2) obtaining sodium-based layered zirconium phosphate by using a layered sodium phosphate precursor, sodium acetate and sodium hydroxide; 3) processing titanium powder, aluminum powder and niobium powder to obtain porous alloy powder; 4) preparing nano silver-copper alloy powder; 5) ball-milling the products of 2) and 3) and 4) to obtain a spraying material, and spraying the spraying material on the surface of the impeller by adopting a plasma spraying process, so that the impeller can be treated. According to the invention, the smooth and flat coating is formed on the surface of the impeller of the mortar pump, so that the adhesive force between the impeller and the fluid medium is reduced, and the adhesion of the fluid on the surface of the impeller is reduced, thereby realizing the technical effect of reducing the damage of the fluid medium to the impeller.
Description
Technical Field
The invention belongs to the technical field of impeller machining, and particularly relates to a treatment process for improving damage of a fluid medium to an impeller of a mortar pump.
Background
The mortar pump belongs to cantilever type single-stage single suction centrifugal pump, is specially designed and developed for conveying liquid containing fine particles and slurry liquid, is a common device in a factory, and has wide application fields, such as: thermal power generation, metal smelting, phosphate sulfate fertilizer, iron and steel enterprises and the like. The mortar pumps have different purposes, different fluid media transportation, different flow rates and ranges of lift, because of the different structural forms and different materials, but all the mortar pumps have an essential component, namely an impeller, which provides flow force for the fluid media through rotation so as to realize the fluid transportation. However, due to different use environments and purposes of the mortar pump, the conveyed fluid media are different, a lot of fluid media can damage the impeller, especially when slurry liquid is conveyed, the fluid is easy to adhere to the impeller, the solution can damage the impeller, and the normal work and operation of the mortar pump can be influenced when the adhesion is serious.
Therefore, the adhesive force of the conveyed fluid medium on the surface of the impeller is reduced, the adhesion of the fluid on the impeller is reduced, and the method plays an important role in maintaining the normal operation of the mortar pump.
