DEHYDRATION OF HYDRAULIC FLUID BY PERVAPORATION AT BLOWING

摘要

The invention relates to a method for dehydrating a hydraulic fluid stream in a hydraulic system. The inventive method consists in separating water from the hydraulic fluid by pervoparation with the aid of a membrane which is permeable for gas and water and impermeable for the hydraulic fluid. Said invention also relates to a device for carrying out said method and to the use the inventive device for an aircraft. The inventive membrane is embodied in the form of a U-shaped tube (4) or a tube bundle fed with air by means of a fan (2). In the preferred embodiment, the ratio between the volumetric rates of a blowing gas and the hydraulic fluid is equal to 1:5.
