Abstract

UN INTERRUPTOR DE TUBO PARA UNA BOMBA DE LODOS DE CILINDRO DOBLE ESTA PROVISTO DE TAL MODO QUE INCLUYE UN TUBO (202) DE OSCILACION, UN ANILLO (204) SOPORTE Y UN MIEMBRO (206) ELASTICO. LA CONDUCCION (202) DE OSCILACION SE ADAPTA AL BASCULADO EN LA PARTE FRONTAL DE UNA PLACA (5) DE CENTRADO E INCLUYE UNA PARTE (212) DE EXTENSION DISPONIENDO DE UNA SUPERFICIE (214) INTERNA. EL ANILLO (204) SOPORTE ESTA SOPORTADO ENTRE EL EXTREMO DEL TUBO (202) DE OSCILACION Y LA PLACA (5) DE CENTRADO Y ES MOVIL AXIALMENTE DE FORMA RELATIVA CON RESPECTO A LA CONDUCCION (202) DE OSCILACION. EL ANILLO (204) SOPORTE TIENE UNA CAVIDAD (208) FORMADA EN UN EXTREMO, DEFINIDA MEDIANTE UNA SUPERFICIE DE BORDE DE ESCAPE. EL TUBO (202) DE OSCILACION SE ADAPTA PARA RECIBIR EL EXTREMO DEL ANILLO (204) SOPORTE INCLUYENDO LA CAVIDAD (208). LA CAVIDAD (208) DEFINE DE ESTA FORMA UN ESPACIO (222) ANULAR ENTRE EL TUBO (202) DE OSCILACION Y EL ANILLO (204) SOPORTE CON LA SUPERFICIE (214) INTERIOR DE LA PORCION (212) DE EXTENSIONDEL TUBO (202) DE OSCILACION SITUADO EN FRENTE DEL ESPACIO (228) ANULAR. EL MIEMBRO (206) ELASTICO INCLUYE UNA SUPERFICIE (236) INTERIOR RADIAL Y UNA SUPERFICIE (232) DE EXTREMO FRONTAL DE ESCAPE QUE CORRESPONDE Y ENSAMBLA LA SUPERFICIE (222) DE CONTORNO DEL ANILLO (204) SOPORTE. EL MIEMBRO (206) ELASTICO ESTA SOPORTADO ENTRE EL TUBO (202) DE OSCILACION Y EL ANILLO (204) SOPORTE DENTRO DEL ESPACIO (228) ANULAR. LA SUPERFICIE (214) INTERIOR DE LA PORCION (212) DE EXTENSION DEL TUBO (202) DE OSCILACION ESTA DISPUESTO SIN RIGIDEZ DE FORMA QUE GENERALMENTE NINGUNA PARTE DE LA TUBERIA (202) O TUBO DE OSCILACION CONTACTAN LA PORCION (236) INTERNA RADIAL DEL MIEMBRO (206) ELASTICO.
