在车辆检修过程中,小田急电铁公司用于8200型车辆上的RC型空气压缩机接连出现润滑油乳化故障,部分压缩机出现润滑性能降低,从而使得压缩机旋转体损伤导致不能起动等故障,并使更换空气压缩机及更换润滑油作业变得频繁。文章介绍了该公司对防止RC型空气压缩机的润滑油乳化措施开展研究的概况、乳化原因的调查、实施对策后取得的成果。
During the overhaul of the vehicle, the RC type air compressor used on the 8200-type vehicle by Odakyu Electric Railway Corporation appeared in series with the lubricant emulsification failure, and the lubrication performance of some of the compressors decreased. As a result, damage to the compressor rotating body caused failure to start, And to replace the air compressor and replace the oil operations become frequent. This article describes the company to prevent the RC-type air compressor lubricant emulsification to carry out an overview of the survey, the cause of the investigation of the investigation, the results achieved after the implementation of countermeasures.
