环形接力器是五十年代后期出现的设备,由于结构简单、布置紧凑、不涉及厂房水工建筑物等特点而得到较为广泛的应用。据不完全统计,目前国内至少有14座水电厂29台不同型号的水轮发电机组采用了环形接力器。运行实践表明,由于环形接力器密封装置的设计、制造及安装调整等多方面的原因,大多数国产机组的环形接力器都存在密封失效快、漏渗油严重等缺陷,既给机组的安全经济运行带来重大损失,也影响了环形接力器的推广使用。因此如何提高环形接力器
Ring relay is the equipment appeared in the late fifties, due to its simple structure, compact layout, does not involve the characteristics of plant hydraulic structures and has been more widely used. According to incomplete statistics, at present there are at least 14 hydropower plants in China with 29 different types of hydroelectric generating units adopting toroidal relay. Operation practice shows that due to many reasons such as the design, manufacture, installation and adjustment of the ring relay sealing device, most of the ring relay of domestic units have the defects of rapid sealing failure, serious leakage of oil and so on, which not only gives the unit a safe and economical Running a major loss, but also affected the promotion of the use of toroidal relay. So how to improve the ring relay
