Abstract

Aparato manorreductor de etapas múltiples y método correspondiente para reducir la presión en el interior de un módulo que requiere un vacío. El elemento manorreductor para el interior del módulo tiene una bomba de vacío para una primera reducción de presión en el interior del módulo y una bomba de refuerzo para una segunda reducción de presión en el interior del módulo cuando una presión interna del módulo alcanza una primera presión predeterminada. La reducción de presión en el módulo se realiza automáticamente, y una vez terminada, se compara la presión interna del módulo con una segunda presión predeterminada, con lo que se visualiza si se ha realizado la vacuodeshidratación de forma normal o no. La reducción de presión se efectúa automáticamente en un corto tiempo, se reduce el número de operarios y el coste de fabricación del módulo. Es de aplicación en la fabricación de aparatos electrodomésticos.Multi-stage pressure reducing device and corresponding method to reduce the pressure inside a module that requires a vacuum. The pressure reducing element inside the module has a vacuum pump for a first pressure reduction inside the module and a booster pump for a second pressure reduction inside the module when an internal pressure of the module reaches a first pressure default The pressure reduction in the module is performed automatically, and once finished, the internal pressure of the module is compared with a second predetermined pressure, which shows whether the vacuum dehydration has been performed normally or not. The pressure reduction is carried out automatically in a short time, the number of operators and the manufacturing cost of the module are reduced. It is applicable in the manufacture of household appliances.
