Summary

Frequent failures of hydrogen gas compressors lead to costly and time-consuming maintenance expenditures in hydrogen refueling stations (HRSs). To decrease the unscheduled downtime and avoid catastrophic accidents, fault diagnosis and full lifecycle health management are the inevitable development direction of the hydrogen safety system. This paper proposes a novel fault diagnosis method based on the correlation relationship of oil pressure and gas pressure to conduct performance evaluation and failure detection for the compressor and its core components. As well, the non-destructive condition monitoring requirement for hydrogen scenario safety was met by strain and acoustic emission (AE) measurements, which provided a non-intrusive condition monitoring method and system. The methods were validated with fault diagnosis cases of compressors including spool wear of the overflow valve and piston ring wear. Further, by integration of the wireless signal acquisition and transmission technology, as well as the above methods, a health management system for full lifecycle online administration and a portable all-in-one instrument for prompt diagnosis were developed and utilized in HRSs. The results and application show that the proposed method is qualified to monitor the operating conditions and identify the failure of compressors accurately and safely. This provides this system with a promising application prospect for full lifecycle management of compressors in HRSs.
