由于水轮机补气装置不良或补气不当,而造成水轮机的气蚀是非常严重的,这种气蚀主要是造成水轮机轮翼腐蚀和吸出管钢板损坏的原因。轮翼的腐蚀主要是由于补气不良所直接引起的,腐蚀的发展速度很快,腐蚀深度很大,运行时间不长就需要停机补焊。吸出管钢板的破坏主要是由于补气不良或运行方式不当所引起的。因为补气不良或运行方式不当使吸出管产生长期频繁而剧烈的振动,由于钢板和混凝土 The cavitation of the turbine is very serious as a result of the improper compensating mechanism or the qi of the turbine. The cavitation is mainly caused by the erosion of the turbine wing and the damage of the pipe of the aspirating pipe. Rotor wing corrosion is mainly caused by poor gas directly caused by the corrosion of the rapid development of a great depth of corrosion, running time is not long need to stop welding repair. Suction tube plate damage is mainly due to poor qi or improper operation caused by the way. Because of poor qi or improper operation of the suction pipe to produce long-term frequent and intense vibration, due to steel and concrete
