Abstract
For the phenomenon of governor oil pump pumping frequently in the FeiLaiXia power plant 4# units, the analysis get a conclusion is the blade relay device was broken, and find out the direct reason is the Blade relay cylinder Roulette bolt falled off in open cavity, scraping in the gap between the piston and cylinder, caused cylinder body burst apart, lead to the blade relay closed and open cavity string of oil.the damaged blades relay cylinder and piston got through soldering, laser Molten and surface Lathe Roughing Operation, then, the blade relay device was fitted back, as a result, the phenomenon of oil pump was disappeared, and the 4# units running in good condition now.关键词
