Abstract

EN LA MAQUINA ELECTRICA REFRIGERADA POR GAS LAS VARILLAS DE BOBINADO DEL ESTATOR, UNIDAS ENTRE SI MECANICA Y ELECTRICAMENTE MEDIANTE OJETES METALICAS (7) POR FUERA DEL CUERPO DE CHAPA DEL ESTATOR (2) EN EL ESPACIO DE LA CABEZA DEL BOBINADO, ESTAN PROVISTAS DE CAPERUZAS (8), QUE RODEAN DE MODO PRACTICAMENTE COMPLETO EL OJETE DEJANDO LIBRES UNO O VARIOS CANALES (9) QUE DISCURREN CASI AXIALMENTE. ESTOS CANALES (9) ESTAN ABIERTOS HACIA EL CUERPO DE CHAPA DEL ESTATOR (2). LA CAPERUZA (8) PRESENTA EN SU EXTREMO DEL LADO DE LA PARED DE SEPARACION UNA ABERTURA (10) QUE ESTA EN UNION LIBRE CON LOS CANALES CITADOS (9). DESDE ESTA ABERTURA CONDUCE UN TUBO FLEXIBLE (11) DIRECTAMENTE A LA CAMARA DE ASPIRACION (14) DEL VENTILADOR (5). COMO CONSECUENCIA DE LA DIFERENCIA DE PRESION ENTRE LA CAMARA DE ASPIRACION (14) Y EL ESPACIO DE LA CABEZA DE BOBINADO (13) FLUYE UNA PARTE DEL LIQUIDO REFRIGERANTE TRANSPORTADO POR EL VENTILADOR (5) A TRAVES DE LOS CANALES CITADOS Y ENFRIA LOS EXTREMOS DE LAS VARILLAS Y LOS OJETES (7).
