Abstract
Se provee una bomba centrífuga cuyos componentes principales, rotor y voluta, están hechos principalmente a partir de piezas de acero. Cada pieza puede ser fácilmente reemplazable. Cada pieza puede presentar una cara, la del lado interno a la voluta, una superficie con mayor resistencia a la abrasión o desgaste. Además se provee una bomba centrífuga donde la periferia de su sección central es relativamente plana. El método para fabricar la bomba centrífuga, que consiste en preparar un despiece de los componentes de la bomba centrífuga, rotor y voluta. Estos despieces tomarán su forma dependiendo de dónde se ubiquen en la bomba ya terminada. Los bordes de los despieces pueden presentar biseles para la soldadura. Una vez que las piezas se van colocando en posición, se rellenan las uniones con el suficiente material de aporte requerido. El método para reparar la bomba centrífuga que consiste en detectar la pieza o piezas desgastadas, retirarlas de su posición por llama oxiacetiénica, corte por soldadura o disco abrasivo. Reemplazarlas por piezas equivalentes que se sueldan en las posiciones correctas.A centrifugal pump is provided whose main components, rotor and volute, are mainly made from steel parts. Each piece can be easily replaceable. Each piece can have a face, that of the internal side to the volute, a surface with greater resistance to abrasion or wear. In addition, a centrifugal pump is provided where the periphery of its central section is relatively flat. The method of manufacturing the centrifugal pump, which consists in preparing an exploded view of the components of the centrifugal pump, rotor and volute. These wakes will take their shape depending on where they are located in the pump already finished. The edges of the ropes may have bevels for welding. Once the pieces are placed in position, the joints are filled with enough required input material. The method to repair the centrifugal pump that consists of detecting the worn part or parts, removing them from their position by oxyacetienic flame, welding cutting or abrasive disk. Replace them with equivalent parts that are welded in the correct positions.
