水轮机导水机构由底环、活动导叶、顶盖、套筒、拐臂、双连臂、调速环等组成。根据技术规程要求,导水机构必须要进行预装,以便发现问题,对设备进行及时处理,给机组正式安装打下可靠的基础。导水机构顶装后要全部拆下来,待水涡轮吊入机坑就位安装后,再开始正式安装。这样一拆一装就要花费较长时间,直接影响到主机安装的直线工期,如果将导水机构预装好后,整体吊出,再整体吊入安装,就可以缩短直线工
Turbine water guide mechanism by the bottom ring, movable guide vane, roof, sleeve, crank, double hinged arm, speed control ring and other components. According to the requirements of technical regulations, the water guide mechanism must be pre-installed in order to find problems, timely treatment of equipment, the official installation of the crew to lay a reliable foundation. After the top-mounted water guide mechanism to be removed all the way, until the water turbine hanging into the pit installed in place after the official installation. Such a disassembly will take a long time, a direct impact on the host installation of the straight-line duration, if the pre-installed aqueduct, the overall hoisting, and then hanging into the overall installation, you can shorten the line
