說明：
四川漢源(yuan)大渡河瀑布溝水(shui)電(dian)(dian)站是(shi)(shi)一座以發電(dian)(dian)為主(zhu)，兼有(you)防(fang)洪(hong)攔(lan)沙等綜合效(xiao)益(yi)的(de)(de)特大型水(shui)利水(shui)電(dian)(dian)樞紐工程，共有(you)四孔(kong)弧門(men)(men)，其中三孔(kong)表孔(kong)弧門(men)(men)，閘(zha)(zha)門(men)(men)開度(du)(du)為16米，另有(you)一孔(kong)是(shi)(shi)深孔(kong)泄(xie)洪(hong)洞弧門(men)(men)，閘(zha)(zha)門(men)(men)開度(du)(du)是(shi)(shi)15米。 該項目初期使用(yong)的(de)(de)是(shi)(shi)副(fu)拉缸，后來(lai)改成鋼(gang)絲繩，但深孔(kong)泄(xie)洪(hong)風力(li)大，汛期啟閉頻繁，鋼(gang)絲繩也(ye)滿足不了現場需求，最后改用(yong)我公司生產的(de)(de)靜(jing)磁柵閘(zha)(zha)門(men)(men)開度(du)(du)傳感器。為配合該項目的(de)(de)正常(chang)使用(yong)，我公司分三次經過兩個泄(xie)洪(hong)周期將(jiang)其全部(bu)改造完畢，糾(jiu)偏精度(du)(du)能(neng)達(da)到8mm，運行效(xiao)果良(liang)好！
說明：
恩(en)施(shi)清江攔河(he)壩工程(cheng)位于(yu)(yu)湖北(bei)省恩(en)施(shi)州，是恩(en)施(shi)州城市景(jing)觀工程(cheng)。該項(xiang)目共有翻(fan)板(ban)門(men)9扇(shan)，由液壓油缸(gang)(gang)(gang)啟(qi)閉，18缸(gang)(gang)(gang)同步運行。由于(yu)(yu)油缸(gang)(gang)(gang)安裝于(yu)(yu)水底，要求(qiu)傳感(gan)(gan)器(qi)(qi)能常年(nian)水下工作，防護等級(ji)達到(dao)IP68，且(qie)為(wei)保證啟(qi)閉機(ji)的多缸(gang)(gang)(gang)同步要求(qiu)，對傳感(gan)(gan)器(qi)(qi)精(jing)度要求(qiu)較高。該項(xiang)目選(xuan)用的靜(jing)磁(ci)柵傳感(gan)(gan)器(qi)(qi)從傳感(gan)(gan)器(qi)(qi)本身到(dao)限位開(kai)關、到(dao)電纜連接頭(tou)均為(wei)IP68防護等級(ji)，測(ce)量(liang)精(jing)度也(ye)達到(dao)0.2mm。自通水運行以來，靜(jing)磁(ci)傳感(gan)(gan)器(qi)(qi)運行穩定，測(ce)量(liang)精(jing)準，為(wei)閘門(men)安全和良(liang)好運行提供了有力保障。
