　　A+K環(huán)楔流量計是一種廣泛應(yīng)用于工業(yè)領(lǐng)域的流量計。它適用于液體、氣體等動態(tài)或靜態(tài)介質(zhì)的流量測量，主要原理是根據(jù)壓降測量法來實現(xiàn)流量的測定。然而，在長期的使用過程中，也會遇到一些故障和問題。本文將討論A+K環(huán)楔流量計常見的故障和維護方法。</div><div> </div><p align="center"><img src="https://img63.ybzhan.cn/9/20230423/638178385028825625643.jpg" width="450" height="450" align="middle" alt="" /></p><p> </p><div>　　工作原理：</div><div> </div><div>　　A+K環(huán)楔流量計是基于伯努利定理和連續(xù)性方程構(gòu)建的，簡單來說，它是通過測量管道截面區(qū)域內(nèi)掉壓與流量之間的關(guān)系來實現(xiàn)流量測量的。儀表兩側(cè)的差壓變化正比于介質(zhì)的流速，可用于推算流量。</div><div> </div><div>　　常見故障及解決方法：</div><div> </div><div>　　1.環(huán)楔積垢</div><div> </div><div>　　在使用時，有些介質(zhì)中含有顆粒物，如沙子、泥土、細(xì)菌等雜質(zhì)，這些雜質(zhì)會在管路中形成污垢，進而會導(dǎo)致環(huán)楔穴孔堵塞。通常，發(fā)現(xiàn)穴孔堵塞后，需要使用溶劑進行清洗，故此情況可以通過經(jīng)常進行管路清洗來避免。</div><div> </div><div>　　2.環(huán)楔積垢</div><div> </div><div>　　由于介質(zhì)中含有鹽分，液體在管道中運動后，計量部分的表面會產(chǎn)生腐蝕或結(jié)晶，導(dǎo)致環(huán)楔坑槽測量不準(zhǔn)確。通常，應(yīng)將儀表人工拆卸，使用酸溶解清除積垢并防止沉積。</div><div> </div><div>　　3.流量信號異常</div><div> </div><div>　　若出現(xiàn)流量通告異?；蚴请y以讀取，則可能是由破損、老化或連接線路不良引起的。如需更換組件，必須明確注明設(shè)備型號，減輕相互之間的錯誤連接所帶來的問題。</div><div> </div><div>　　4.環(huán)楔壽命</div><div> </div><div>　　環(huán)楔壽命隨著使用時間的延長而逐漸衰退，特別是在高溫環(huán)境下使用。如果發(fā)現(xiàn)機器的使用過程中對測量值容忍度大，則需要定期檢查環(huán)楔是否正常，并及時更換損壞的部位以達(dá)到精度的提升。</div> </div> <div id="h3pffdr" class="ly_PrevNext"> <ul> <li>上一篇：<a
