众所周知.水轮机轴封水装置在运行中一旦失效喷水,对水导轴承的安全运行有很大的威胁。西洱河四级电站自七一年投产后1—3机均采用老式的盘根型封水装置。从实践中发现,这种结构有下列缺陷: 1.运行中一旦漏水量增大,如需处理就必须停机。 2.为了减少漏水,势必压紧盘根,但这义会对水轮机轴产生磨损。随着主轴磨损的 As we all know, turbine shaft sealing device in the event of failure of water spray, the safety of the water guide bearing a great threat. Xi’erhe four power plants have been put into operation 1-3 years old since the year of 1981 have adopted the old packing type water sealing device. Found from practice, this structure has the following shortcomings: 1. Run once the amount of water leakage, for handling must be shut down. 2. In order to reduce water leakage, it is bound to compress the packing, but this will be on the turbine shaft wear and tear. With the spindle worn
