Abstract

SE PROPORCIONA UNA BOMBA DE CAVIDAD MEJORADA DE ACCION PROGRESIVA (CP).PRIMERAMENTE, LA BOMBA CP COMPRENDE UN ROTOR CONECTADO A UN MOTOR A TRAVES DE UN EJE CONDUCTOR QUE SE ENCUENTRA AISLADO DEL MATERIAL QUE FLUYE POR CONDUCTO DE LA CAMARA DE SUCCION DE LA BOMBA, POR LO QUE IMPIDE QUE EL MATERIAL BOMBEADO LLEGUE A LAS JUNTAS DEL EJE CONDUCTOR POR MEDIO DE SELLOS DEFECTUOSOS. EN OTRO ASPECTO, LA BOMBA CP COMPRENDE UN CONJUNTO DE ROTOR QUE COMPRENDE UN EJE DE ROTOR QUE ESTA UNIDO A UN MIEMBRO ROTOR MEDIANTE UN MIEMBRO CONECTOR QUE TIENE UNA CAPACIDAD POR INDUCCION TERMICA PARA DETECTAR FALLOS ESTRUCTURALES, LO CUAL PROVEE UN MECANISMO DE PROTECCION CONTRA FALLOS POR MANIPULACION INDEBIDA A PRUEBA DE RECALENTAMIENTO. EN UNA MODALIDAD PREFERIDA, EL MIEMBRO CONECTOR ES FABRICADO DE UNA ALEACION FUNDIBLE A BAJA TEMPERATURA QUE SE TRANSFORMA EN ESTADO LIQUIDO A UNA TEMPERATURA SOBRE LA CUAL LA OPERACION DE LA BOMBA YA NO ES SEGURA. SI LA BOMBA SE RECALIENTA, COMO RESULTADO DE LA OPERACION EN LASTRE O BOMBEO EN SECO, EL MIEMBRO CONECTOR SE FUNDE DANDO POR TEMINADO LA RELACION DE TRANSMISION ENTRE EL EJE DE ROTOR Y EL MIEMBRO ROTOR. LA BOMBA CP MEJORADA ES PARTICULARMENTE UTIL PARA BOMBEAR EXPLOSIVOS.
