轴瓦温度跳变的原因分析及处理

Reasons analysis and treatment on the hopping of unit bearing temperature

机组轴承的测温电阻质量参差不齐，测温电阻电缆长期浸泡在导轴承、推力轴承油槽里，使电缆外皮变硬变脆。电缆长期受高温油流的冲击，造成运行中测温电阻电缆断裂。机组长时间运行在振动区，造成测温回路端子松动。

The difference in quality and used in thrust bearing groove and journal bearing groove for a long time results temperature resistance＇ s sheath stiff and brittle. The impact of high temperature oil flow for a long time causes the cable of running temperature resist- ance broken. The long time running in vibration area of units causes temperature loop terminal flexible.
