毛主席教导我们说:“世界上的事情是复杂的,是由各方面的因素决定的。”每一台机组每一块叶片的形状都不一样,每块叶片的间距也都不一致,每块叶片的气蚀程度也不同,有的叶片经运转3年以上才开始有点气蚀,而有的叶片经运转半年就气蚀了,这说明叶片的形状对气蚀影响很大。这里根据现场焊修气蚀叶片谈谈体会:1.叶片由于有凸面,使凸面下方脱流,形成真空,产
Chairman Mao taught us: “The things in the world are complicated and determined by various factors.” Each leaf of each unit has a different shape and the pitch of each leaf is also different. Each leaf Of the degree of cavitation are also different, and some of the leaves after the operation of more than 3 years began a little cavitation, and some of the leaves after operation for six months cavitation, indicating that the shape of the leaves a great impact on cavitation. Here according to the scene welding repair cavitation leaves talk about experience: 1. Blade due to the convex surface, so that the underside of the convex surface to form a vacuum, production
