Development of a Progressive Design of a Ground Centrifugal Pump

Abstract

The processes and technologies of gas-flame surfacing of metal powders are considered, promising modern gas-thermal methods for creating a hardened surface layer of machine parts are established. The use of a specific surfacing method from the considered ones is due to the production conditions, the number, shape and size of the surfaced parts, the permissible share of the base metal in the surfaced, technical and economic indicators, and for restorative surfacing – the amount of wear. The choice of the type of deposited metal and, consequently, the grade of the filler material is made in accordance with the type of working loading of the deposited part. Therefore, when choosing the type of deposited metal, they focus on the prevailing type of wear. Based on the conducted studies of the gas-thermal method of applying wear-resistant coatings, a new design of the impeller of a centrifugal ground pump has been developed.
