头脑风暴法提高机组导轴承间隙测调效率的尝试

Attempt to improve efficiency of guide bearing gap by brainstorming

万家寨水电站1号水轮发电机组自1999年8月小修以来,水轮机导轴承和发电机上导轴承间隙的测量、调整工作每次进行约5天时间,分析了其测调效率不高的原因,并提出了处理办法,使测调工作缩短为2.5天,缩短了1号水轮发电机组小修时间。

Since the minimal repair of unit no.1 of Wanjiazhai Hydropower Station in August 1999, the measurement and adjustment of guide bearing gap between turbine and generator has been conducted for about 5 days each time. This article analyzes the cause of inefficient measurement and adjustment. Measures are given to reduce the time of measurement and adjustment to 2.5 days, thus the time for minor repair of unit no.1 is shortened.
