電磁流量計運行時維護與故障排查

 智能電磁流量計在停機即不運用的時候，咱zan們men要yao對dui流liu量liang計ji采cai納na科ke學xue合he理li的de保bao護hu和he養yang護hu辦ban法fa。用yong戶hu在zai采cai購gou電dian磁ci流liu量liang計ji之zhi後hou有you段duan時shi刻ke會hui出chu現xian丈zhang量liang數shu據ju不bu精jing確que的de時shi分fen，這zhe是shi什shen麼me因yin素su呢ne，其qi實shi不bu是shi電dian磁ci流liu量liang計ji的de質zhi量liang問wen題ti，而er是shi你ni沒mei有you依yi照zhao闡chan明ming書shu裏li的de辦ban法fa進jin行xing養yang護hu。

一、電磁流量計保護之零點查看和調整　　智zhi能neng電dian磁ci流liu量liang計ji投tou入ru運yun轉zhuan前qian，通tong電dian後hou必bi須xu在zai電dian磁ci流liu量liang傳chuan感gan器qi充chong溢yi液ye體ti靜jing止zhi狀zhuang態tai下xia調tiao整zheng零ling點dian。投tou入ru運yun轉zhuan後hou亦yi要yao對dui於yu運yun用yong條tiao件jian定ding時shi停ting流liu作zuo零ling點dian查zha看kan;特別對堆積、yiwurandianji，fuhanguxiangdefeiqingjieye，zaiyunzhuanqianqiyingduozuozhakan，yiqudejingliquedingzhengchangzhakanzhouqi。goutongjicifangfadedianciliuliangjiyujuxingbojibi

    電磁流量計停機怎樣保護?舉ju兩liang個ge堆dui積ji層ceng發fa生sheng毛mao病bing的de應ying用yong失shi誤wu的de例li子zi。一yi個ge是shi石shi油you鑽zuan探tan固gu井jing工gong程cheng中zhong，灌guan注zhu水shui泥ni漿jiang的de流liu總zong量liang是shi主zhu要yao技ji術shu參can數shu，經jing常chang用yong高gao壓ya電dian磁ci流liu量liang計ji。儀yi表biao間jian歇xie運yun用yong，用yong畢bi後hou以yi清qing水shui衝chong洗xi傳chuan感gan器qi丈zhang量liang管guan，其qi餘yu時shi刻ke是shi空kong管guan。由you於yu清qing潔jie不bu徹che底di，丈zhang量liang管guan內nei壁bi殘can留liu水shui泥ni漿jiang固gu化hua成cheng薄bo層ceng
，近jin二er個ge月yue積ji累lei構gou成cheng絕jue緣yuan層ceng
，包bao覆fu了le全quan部bu電dian極ji外wai表biao
，致zhi使shi運yun轉zhuan不bu正zheng常chang到dao終zhong究jiu不bu能neng作zuo業ye。　　另一個是電解切削技術驗設備上，用電磁流量計操控飽滿食鹽水流量，間隙運用一段期間後發現流量信號逐漸削弱，2個月後信號為零。因素是電解切削過程中氧化鐵堆積管壁，構成短路所造成的。鏟除層積即當即康複正常。　

　二、智能電磁流量計保護之定時查看傳感器電功能　　電磁流量計停機怎樣保護?首shou要yao，粗cu略lve地di丈zhang量liang電dian極ji間jian電dian阻zu。斷duan開kai傳chuan感gan器qi與yu轉zhuan換huan器qi間jian信xin號hao連lian線xian，傳chuan感gan器qi內nei充chong溢yi液ye體ti，用yong萬wan用yong表biao丈zhang量liang兩liang電dian極ji與yu接jie地di端duan的de電dian阻zu值zhi，是shi不bu是shi在zai製zhi造zao廠chang規gui定ding值zhi範fan圍wei內nei
，且qie所suo測ce得de兩liang值zhi大da體ti一yi樣yang。記ji載zai下xia初chu次ci丈zhang量liang的de電dian阻zu值zhi
，此ci值zhi對dui今jin後hou判pan別bie傳chuan感gan器qi毛mao病bing因yin素su(如堆積層是導電的仍是絕緣的)是有用的。　　其次，將傳感器放空液體，擦淨內壁
，待徹底枯燥後用兆歐計丈量兩電極和接地端子間的電阻。
