Abstract
DISPOSICION CONSTRUCTIVA DE UNIDAD MOTOVENTILADORA PARA INSTALAR EN UN EQUIPO DE LIMPIEZA, POR VACIO, DE SUELOS Y ALFOMBRAS HUMEDOS. LA CAMARA DE VENTILADOR (60) TIENE UNA PARED (33) PROVISTA DE UN SOPORTE PARA UN COJINETE (40) SOBRE EL QUE APOYA EL ARBOL (15) DE ACCIONAMIENTO DEL VENTILADOR, EXISTIENDO UNA ENTRADA PARA AIRE DE OBTURACION, QUE ESTA DISTANCIADA DEL CONDUCTO DE AIRE DE TRABAJO O DEL AIRE DE REFRIGERACION DEL MOTOR. EN FUNCIONAMIENTO NORMAL EL AIRE DE OBTURACION SE PUEDE IMPULSAR HACIA EL INTERIOR DE LA CAMARA DEL VENTILADOR, CON LO QUE SE BARRE EL LIQUIDO ARRASTRADO POR EL AIRE DE TRABAJO, EXISTIENDO UNAS VALVULAS DE RETENCION QUE IMPIDE LA CIRCULACION INVERSA DEL AIRE Y DEL LIQUIDO A TRAVES DEL PASAJE QUE CONDUCE EL AIRE DE OBTURACION A LA CAMARA DE VENTILACION.
