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 comprises the following specific methods: 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) And (3) ball-milling the products of the steps 2), 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 processing, and particularly relates to a treatment process for improving damage of a fluid medium to a mortar pump impeller.
Background
The mortar pump belongs to a cantilever type single-stage single-suction centrifugal pump, is specially designed and developed for conveying liquid containing fine particles and pasty liquid, is common equipment in factories, and has wider application fields, such as: thermal power generation, metal smelting, phosphate fertilizer sulfate, iron and steel enterprises and the like. Mortar pumps have different applications, different fluid media and different flow and lift ranges, because the structural forms are different, and the materials are different, but all the mortar pumps are provided with an essential component, namely an impeller, which provides flow force for the fluid media through rotation, so that the fluid is conveyed. However, because the mortar pump has different use environments and purposes, the transported fluid media are different, wherein a plurality of fluid media can damage the impeller, especially when slurry liquid is transported, the fluid is easy to adhere to the impeller, not only the solution can damage the impeller, but also 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 mortar pump has an important function for maintaining the normal operation of the mortar pump. For example, chinese patent CN2017105385466 discloses a water pump guide vane wheel with self-cleaning performance and a processing method thereof, wherein a protective film is formed on the surface of the water pump impeller to increase the capability of the guide vane wheel for eliminating and decomposing adherends, thereby reducing the survival time of bacteria and fungi on the guide vane wheel, reducing the pollution degree of the guide vane wheel, ensuring the cleaning degree of loose water of the water pump, avoiding secondary pollution, and ensuring the normal operation and working of the water pump; however, for the fluid medium containing fine solid particles conveyed in the mortar pump, the technical scheme can not solve the technical problems that the fluid medium is adhered to the impeller, the weight of the impeller is increased, and the normal operation of the mortar pump is affected, although the fluid medium can play a role in eliminating and decomposing bacterial microorganisms in the fluid.
