我厂3号发电机端盖,由于长时间的运行,端盖的接触面已经磨损,运行中漏氢比较严重。虽经多次检修,都未得到彻底解决。1985年该机组大修时,我们采用金属涂镀工艺进行修复。涂镀后的端盖结合面平整、严密,运行中未再发生漏氢现象,效果很好。现将涂镀的工艺过程介绍如下:一、涂镀用设备规范所采用的涂镀电源设备是 TD—60型涂镀电源机,输入交流电压为220伏±10%,50Hz,输出直流电压0～35伏,电流分0～6安及0～60安两档;交流电压0～40伏,
I plant on the 3rd generator cover, due to the long run, the cover of the contact surface has been worn, running more serious leakage of hydrogen. Despite repeated maintenance, have not been completely resolved. When the unit was overhauled in 1985, we used a metal plating process to repair it. Coated after the end cover with a smooth surface, tight, running no leakage of hydrogen occurs, the effect is very good. Coating process will now be introduced as follows: First, the coating equipment specifications used coating power equipment is TD-60-type coating power supply, the input voltage is 220 volts ± 10%, 50Hz, the output DC voltage 0 ~ 35V, current 0 ~ 6A and 0 ~ 60A two gears; AC voltage 0 ~ 40V,
