Abstract

UNA INSTALACION HIDRAULICA.TIENE UNA BOMBA (12), UNA VALVULA (28) PARA EL MANDO DE LA ALIMENTACION A UN PUNTO DE CONSUMO (34), UNA TUBERIA DE ALIMENTACION (16) Y UNA CONDUCCION DE SEN/ALES (46, 48, 52), ESTANDO UNIDAS POR EL LADO DE PRESION DEL PUNTO DE CONSUMO LA TUBERIA DE ALIMENTACION (16) Y LA CONDUCCION DE SEN/ALES (46, 48, 52) CUANDO LA VALVULA (28) ESTA DESPLAZADA DESDE SU POSICION NEUTRA. EN ESTA INSTALACION HIDRAULICA (10), LA BOMBA (12) ESTA HECHA COMO BOMBA REGULADORA EN FUNCION DE LA DEMANDA, LA CONDUCCION DE SEN/ALES (46, 48, 52) PARA EL MANDO DE LA BOMBA ESTA CONECTADA A ESTA Y LA CONDUCCION DE SEN/ALES ESBLOQUEABLE TAN PRONTO COMO LA PRESION EN ELLA REINANTE SEA MAYOR QUE LA ENTREGADA AL PUNTO DE CONSUMO (34) A TRAVES DE LA TUBERIA DE ALIMENTACION (16).
