| Abstract: | In this paper,the risk analysis of PSA miniature oxygen concentrator is carried out by means of fault tree analysis(FTA) and failure modes and effects analysis(FMEA).The main factors which may bring the concentrator to failure are the air compressor failure and the control system failure.To get high reliability of this kind of product,it is necessary to control all the processes,such as design,inspection and production.It is also showed that the risk of the concentrator is small and the hazard grade is the lowest,both are acceptable. |
