摘要:
A method for cleaning, method and device for the application of a protective medium to a turbine blade, and a method for placing cooling bores in a turbine blade is disclosed. For this purpose, hot supercritical carbon dioxide is used as a tempering and/or cleaning medium and compressed and decompressed one or more successive times. The cleaning medium is decompressed to a pressure at which the gas assumes a volume that is a multiple of the volume of the compressed cleaning medium in the pressure tank. In so doing, it is possible to remove particulate and other impurities, even from recesses, blind holes, or open hollow spaces.
摘要(中):
公开了一种用于清洁的方法,用于向涡轮叶片施加保护介质的方法和装置,以及用于将冷却孔放置在涡轮叶片中的方法。 为此,将热超临界二氧化碳用作回火和/或清洁介质,并连续压缩和减压一次或多次。 将清洁介质减压至压力,在该压力下,气体的体积是压力罐中压缩的清洁介质的体积的倍数。 在这样做时,即使从凹槽,盲孔或敞开的中空空间中也可以除去微粒和其它杂质。
