科拉特流量計(jì)故障分析

(1)流量控制儀表系統(tǒng)指示值達(dá)到zui小時(shí)，首先檢查現(xiàn)場(chǎng)檢測(cè)儀表，如果正常，則故障在顯示儀表。當(dāng)現(xiàn)場(chǎng)檢測(cè)儀表指示也zui小，則檢查調(diào)節(jié)閥開(kāi)度，若調(diào)節(jié)閥開(kāi)度為零，則常為調(diào)節(jié)閥到調(diào)節(jié)器之間故障。當(dāng)現(xiàn)場(chǎng)檢測(cè)儀表指示zui小，調(diào)節(jié)閥開(kāi)度正常，故障原因很可能是系統(tǒng)壓力不夠、系統(tǒng)管路堵塞、泵不上量、介質(zhì)結(jié)晶、操作不當(dāng)?shù)仍蛟斐?。若是儀表方面的故障，原因有：孔板差壓流量計(jì)可能是正壓引壓導(dǎo)管堵；差壓變送器正壓室漏；機(jī)械式流量計(jì)是齒輪卡死或過(guò)濾網(wǎng)堵等。

(2)流量控制儀表系統(tǒng)指示值達(dá)到zui大時(shí)，則檢測(cè)儀表也常常會(huì)指示zui大。此時(shí)可手動(dòng)遙控調(diào)節(jié)閥開(kāi)大或關(guān)小，如果流量能降下來(lái)則一般為工藝操作原因造成。若流量值降不下來(lái)，則是儀表系統(tǒng)的原因造成，檢查流量控制儀表系統(tǒng)的調(diào)節(jié)閥是否動(dòng)作；檢查儀表測(cè)量引壓系統(tǒng)是否正常；檢查儀表信號(hào)傳送系統(tǒng)是否正常。

(3)流量控制儀表系統(tǒng)指示值波動(dòng)較頻繁，可將控制改到手動(dòng)，如果波動(dòng)減小，則是儀表方面的原因或是儀表控制參數(shù)PID不合適，如果波動(dòng)仍頻繁，則是工藝操作方面原因造成。
