承德县柳河水电站装机容量为3×320kW,水轮机型号为HL-260-WJ-71,发电机型号为SFW320-16/1430。水轮机与发电机之间没有法兰连接,只有两道巴氏合金式轴承、前推力轴承和后径向轴承。整个机组结构非常简单、紧凑、美观大方。 7月上旬的一天,运行人员发现3号机组径向轴承温度偏高。经检查发现甩油环断一根,随后进行停机处理。处理后重新开机并网,不足10min.瓦温升至56℃,不得不再次停机。就这样又往复三次,均不能解决问题,瓦温仍然过高,影响瓦温升高的其它原
Chengde County Liuhe Hydropower Station installed capacity of 3 × 320kW, turbine model HL-260-WJ-71, generator model SFW320-16 / 1430. There is no flange connection between turbine and generator, only two Babbitt bearings, thrust bearings and rear radial bearings. The entire unit structure is very simple, compact, elegant appearance. One day in early July, the runner found that the radial bearing temperature of Unit 3 was high. After the inspection found that oil thrown off a ring, followed by downtime. Reboot after processing and grid, less than 10min. Wawa rose to 56 ℃, had to stop again. In this way, three times reciprocating, can not solve the problem, Wawen is still too high, affecting the other original Wawen
