新疆石河子红山嘴电厂建厂几十年来,由于草害、冰害、砂害较严重,机组蜗壳检查、水下检修很频繁。以前,尾水闸采用的止水形式效果不好。我们经过多次试验、论证,决定采用气囊,同时配装油压装置,解决闸门止水问题。 闸门门叶为平板式钢结构组合件,在门叶止水面设计安装一矩形固定整体式P形气囊,使其与尾水闸闸孔周边结合。并在闸门背面两竖梁4角设置4个液压油缸,配套气
Shihezi Hongshan mouth power plant construction in Xinjiang for decades, due to grass damage, ice damage, sand damage more serious, the unit volute inspection, underwater maintenance is frequent. In the past, the form of water stop used by the tailgate did not work well. After many tests and demonstrations, we decided to use the airbag and equipped with a hydraulic device to solve the problem of water stop in the gate. The gate of the gate is a flat steel structure assembly, and a rectangular fixed integral P-shaped air bag is designed and installed on the water-stop surface of the gate so as to be integrated with the periphery of the tail gate hole. And in the back of the gate two vertical beam 4 corner set 4 hydraulic cylinders, supporting gas
