Abstract

Una bomba con engranaje para transferencias a baja velocidad de lodos líquidos viscosos estimula el crecimiento de partículas suspendidas, tales como los cristales de azúcar, para evitar el aplastamiento de las partículas. La bomba incluye un engranaje de rotor para que se engrane con un engranaje de piñón loco montado excéntricamente soportado sobre un cubo de un cabezal de la bomba que incluye un sello de media luna que se extiende en una abertura que resulta de la excentricidad del engranaje de piñón loco con relación al engranaje de rotor. El engranaje de piñón loco contiene un borde que se extiende radialmente sobre cada perfil del diente, orientado simétricamente sobre pares de dientes separados adyacentemente. Los bordes, configurados para reducir al mínimo el aplastamiento de los cristales que pasan a través de la bomba, acoplar los dientes de acoplamiento del rotor para sellado entre los puertos de entrada y salida de la bomba. Para estimular el crecimiento de cristales, los bordes cubren únicamente del 10% al 30% del área superficial del perfil de cada diente. Para reducir al mínimo el desgaste del diente de engranaje, los bordes están escalonados axialmente entre los pares de dientes adyacentes sucesivos.
