\n\n\n\n

\u00cdndices de fugas<\/a> puede ser enga\u00f1oso. Es posible que vea piezas limpias y brillantes saliendo de su horno incluso cuando el \u00edndice de fugas sugiere un problema. Otras veces, puede notar una decoloraci\u00f3n de las piezas sin ning\u00fan signo de un aumento de la tasa de fugas.<\/p>\n\n\n\n

Se trata de situaciones comunes que pueden llevar a confusi\u00f3n y a la resoluci\u00f3n de problemas adicionales. Echemos un vistazo m\u00e1s de cerca a ambos escenarios, y algunas formas pr\u00e1cticas de localizar el problema antes de pasar horas diagnosticando el problema equivocado.<\/p>\n\n\n\n

Piezas limpias, \u00edndice de fugas sospechoso<\/h3>\n\n\n\n

Una de las razones m\u00e1s comunes por las que puede estar obteniendo una pieza limpia, a pesar de un \u00edndice de fugas superior al esperado, puede ser una junta desgastada en una de las v\u00e1lvulas de relleno o de presi\u00f3n parcial.<\/p>\n\n\n\n

Estos tipos de fugas permiten la entrada de gas inerte en la c\u00e1mara, por lo que es posible que no haya interacci\u00f3n qu\u00edmica entre el gas fugado y las piezas. Sin embargo, una fuga lenta de gas inerte puede causar problemas durante una receta que requiera un vac\u00edo bajo. Por ejemplo, una fuga de gas de proceso puede impedir que el horno alcance el nivel de vac\u00edo necesario para activar la v\u00e1lvula principal de la bomba de difusi\u00f3n.<\/p>\n\n\n\n

La mejor manera de probar esta teor\u00eda es aislar el suministro de gas mediante el uso de la v\u00e1lvula manual para cerrar las l\u00edneas de gas al horno, dibujando el horno en vac\u00edo, y comprobar para ver si todav\u00eda hay una anomal\u00eda en la tasa de fuga.<\/p>\n\n\n\n

Si la tasa de fuga vuelve a la normalidad con todas las v\u00e1lvulas manuales cerradas, probablemente significa que el gas se est\u00e1 filtrando m\u00e1s all\u00e1 de la v\u00e1lvula de relleno o del solenoide de presi\u00f3n parcial, lo que indica que la v\u00e1lvula debe ser reemplazada.<\/p>\n\n\n\n

Como siempre, siga las instrucciones del fabricante para sustituir una v\u00e1lvula. Si va a sustituir una v\u00e1lvula de mariposa, aproveche las ventajas que le ofrece Ipsen. Procedimientos recomendados para instalar una v\u00e1lvula de mariposa<\/a>.<\/p>\n\n\n\n

Recuerde que los \u00edndices de fugas son acumulativos. Muchas fuentes diferentes pueden estar contribuyendo a un alto \u00edndice de fugas, as\u00ed que no se detenga una vez que haya encontrado una v\u00e1lvula con fugas: sea minucioso y aseg\u00farese de detectar todas las fugas a medida que prueba todo el sistema.<\/p>\n\n\n\n

Piezas descoloridas, \u00edndice de fugas constante<\/h3>\n\n\n\n

Las piezas descoloridas son se\u00f1al de que ha entrado gas no deseado, normalmente aire atmosf\u00e9rico, en el horno durante el proceso. Pero, \u00bfc\u00f3mo puede ocurrir esto si no hay alertas de un aumento de la tasa de fugas?<\/p>\n\n\n\n

La respuesta suele ser una fuga o una incursi\u00f3n de aire en el dep\u00f3sito de gas de proceso o en los conductos de servicio de gas.<\/p>\n\n\n\n

A veces puede introducirse aire en el dep\u00f3sito o en los conductos durante un rellenado, o como resultado de la expansi\u00f3n y contracci\u00f3n natural de los conductos de servicio debido a los cambios de temperatura.<\/p>\n\n\n\n

Puede parecer contraintuitivo que las tuber\u00edas de gas bajo presi\u00f3n puedan permitir la entrada de aire ambiente, pero un fen\u00f3meno f\u00edsico llamado la Efecto Venturi<\/strong> puede provocar la entrada de aire atmosf\u00e9rico en la l\u00ednea, desplazando el gas de proceso a medida que sale.<\/p>\n\n\n\n

Antes de suponer que ha entrado aire en el dep\u00f3sito de reserva de gas de proceso, aseg\u00farese de que no hay fugas en ning\u00fan punto de los conductos de gas de proceso mediante una prueba de burbujas. Aseg\u00farese de prestar mucha atenci\u00f3n a cada accesorio y codo.<\/p>\n\n\n\n

\"Leaky<\/figure>\n\n\n\n

Si descubre una fuga de cualquier cantidad, siga todos los protocolos de seguridad de gases de proceso, selle la fuga (por peque\u00f1a que sea) e informe de ella a su punto de contacto de seguridad.<\/strong><\/p>\n\n\n\n

\n \n Obtenga m\u00e1s informaci\u00f3n sobre la seguridad de los gases de proceso aqu\u00ed. <\/a>\n <\/section>\n\n\n\n

Despu\u00e9s de una inspecci\u00f3n minuciosa, si no se descubren fugas en las tuber\u00edas de gas de proceso entre el horno y el dep\u00f3sito, puede ser aconsejable que su gas de proceso comprobado el punto de roc\u00edo<\/a> para detectar cualquier presencia de humedad.<\/p>\n\n\n\n

Consejo: <\/strong>Para evitar bolsas de aire en las tuber\u00edas de proceso despu\u00e9s de rellenar el dep\u00f3sito de gas de proceso o realizar trabajos en una tuber\u00eda de gas, rellene el horno y bombee una o dos veces para asegurarse de que se ha evacuado todo el aire no deseado del sistema y de que todas las tuber\u00edas que van al horno est\u00e1n cargadas correctamente s\u00f3lo con gas de proceso. Si las l\u00edneas de proceso desde el horno hasta el dep\u00f3sito son especialmente largas, es posible que tenga que repetir este ciclo m\u00e1s de dos veces.<\/p>\n\n\n\n
