摘要

通过对神头第一发电厂7号机组运行汽轮机油、补加新油和再生油油样进行红外光谱分析、T501抗氧剂含量分析及不同温度下的开口杯老化试验

发现运行汽轮机油劣化的内在因素是T501抗氧剂完全消耗和补加新油中含有有机酯

外在因素为机组油系统存在过热点

冷油器冷却效果不好

对此提出了改进建议。

Abstract

Through infrared spectroscopy analysis

T501 antioxidant content analysis

and open cup ageing test under different temperature for oil samples from turbine oil in operation of unit no.7 in Shentou Power Plant No.1

from new turbine oil for replenishment

and from the regenerated turbine oil

it is discovered that the internal factors of turbine oil deterioration are the T501 antioxidant being fully consumed and organic ester existing in the newly added turbine oil

and the external factors are over-temperature points are existing in oil system of the unit and the cooling effect of oil cooler is not good.For these

recommendations of improvement have been put forward.
