某公司660 MW机组自投产以来多次发生高中压通流轴 瓦温度升高、轴瓦擀瓦损坏事故，严重影响了机组安全。针对事 故原因，联合设备制造厂采取了一系列的技术措施，并对运行方 式进行优化，有效改善了机组运行工况，杜绝了事故隐患。

The accidents repeatedly occur and have a serious impact on safety since a 660 MW unit comes into operation that bearings temperature in flow part between high and intermediate pressure cylinder increases and bearings damage. Aiming at the causes of accidents, a series of technical measures are adopted and the operation scheme is optimized with equipment manufacturing factory, effectively improving the operating conditions to eliminate potential causes of accidents.
