摘要
对某135 MW机组升负荷过程中出现的汽轮机正向推力瓦温度升高的故障进行分析,找到导致瓦块温度偏高的原因是A4腔漏汽至三抽的排汽不畅,并提出了改进措施。
An analysis is presented,of what caused the temperature,of the front thrust bearing pads,of a 135 MW set, to rise excessively during power escalation. It was found that steam discharge impedement, from cavity A4 to steam extraction No .3, had been the cause. Remedial measures are proposed.
