水封热接装置
本技术涉及水电站钢闸门止水
,更为具体地,涉及一种水封热接装置。
技术介绍
水电站闸门是防洪渡汛和保证水轮发电机组安全运行的重要设备,水封又是水工钢闸门的主要功能装置之一,也是最容易发生故障的部件,其自身质量以及现场安装工艺等因素直接影响水工闸门的止水效果,进而影响水工建筑物的安全运行。闸门漏水原因有多种:一是闸门在汛期进行泄洪时,来回有水动门导致水封磨损级撕裂,造成闸门漏水,如龚嘴水电站溢洪道工作门和冲砂底孔工作门。二是闸门橡胶水封长期浸泡水中深受水中各种化学物质侵蚀和杂物的冲蚀、磨损,如龚嘴水电站机组进水口工作门。三是水封暴露在阳光下受紫外线直接照射而引起的橡胶老化,如上下厂尾水门及溢洪道、冲砂底孔检修闸门;四是安装橡胶水封时水封安装尺寸不准确、安装工艺不正确、水封压缩量不准确、紧固水封压板螺栓力矩不合适都会影响闸门止水效果及使用性能。水封一经损坏,就会影响闸门的正常工作。采用的处理方法是:1、对局部有间隙或压缩量偏小,采用橡胶加垫办法解决。2、如因安装调整和压缩量不当造成的大量漏水,则必须重新进行安装。然而在实际操作中,往往是水封某一段( ...
