本文回顾了150米~3/时制氧机所配气体轴承中压透平膨胀机的研制经过和初步推广应用的情况。指出研制的关键是气体轴承在高转速下工作的稳定性,经不断摸索,现采用橡皮加稳、多排切向小孔供气、统一供气双气膜三种轴承结构,并对三种结构作了详细介绍。最后叔达了轴承材料的组合要求。 This article reviews the 150m ~ 3 / h oxygen generator equipped with gas bearing medium pressure turboexpander developed through the initial promotion and application of the situation. It is pointed out that the key to development is the stability of the gas bearing working under high speed. After continuous exploration, the rubber bearing is adopted to stabilize the gas bearing, multi-row tangential hole gas supply, Structure made a detailed introduction. Finally, the combination of bearing material requirements.
