Abstract

LOS TRANSPORTES HIDRAULICOS COMPRENDEN AL MENOS UNA LINEA QUE CONDUCE A UN CONJUNTO DE MAQUINAS Y QUE SE PUEDE CONECTAR A UNA BOMBA O A UNA RESERVA. CUANDO LA LINEA SE CONECTA AL TANQUE, UNA VALVULA DE SUJECCION DISPUESTA EN LA LINEA MANTIENE UNA PRESION MINIMA EN LA RAMA DE LA LINEA QUE CONDUCE AL CONJUNTO DE MAQUINAS. EL VALOR ACTUAL DE LA PRESION DE LA LINEA ES MEDIDO POR UN MANOMETRO DISPUESTO EN DICHA RAMA DE LA LINEA. SI ESTE VALOR CAE POR DEBAJO DE LA PRESION MINIMA PREDETERMINADA POR LA PRESION DE APERTURA DE LA VALVULA DE SUJECCION, COMO LA DETERMINADA POR UN COMPARADOR, ESTO INDICA LA PRESENCIA DE UNA FUGA, POR MUY PEQUEÑA QUE SEA, EN LA SECCION DE LA LINEA.
