style="color:#333333;font-family:"font-size:16px;background-color:#FFFFFF;"><strong>COD氨氮測定儀這七點(diǎn)日常維護不能出錯</strong></p><p style="color:#333333;font-family:"font-size:16px;background-color:#FFFFFF;"><strong>為了準確掌握污水處理廠(chǎng)每個(gè)處理環(huán)節的運行，必須監視進(jìn)入每個(gè)結構的相關(guān)參數。這些參數中的一些需要手動(dòng)測試，而一些可以由儀表自動(dòng)檢測。COD氨氮測定儀是自動(dòng)檢測水質(zhì)的重要儀器之一。作為污水處理的重要數據監測儀器，這七點(diǎn)日常維護決計不可出錯。</strong></p><p></p><p><strong><img src="https://cos3.solepic.com/20200916/b_4170889202009161634022324.jpg"/></strong></p><p></p><p style="color:#333333;font-family:"font-size:16px;background-color:#FFFFFF;"><strong>&emsp;&emsp;1、日常檢查主要包括檢查COD氨氮測定儀是否工作正常，例如入口和出口管道是否暢通，是否有泄漏以及保持儀器清潔，特別是旋轉部件和易損部件請定期檢查和更換，以防止其損壞導致儀器泄漏和腐蝕。</strong></p><p style="color:#333333;font-family:"font-size:16px;background-color:#FFFFFF;"><strong>2、試劑更換和硫酸單硫酸銀是高腐蝕性試劑，在工作現場(chǎng)容易揮發(fā)和吸收水分，因此應定期更換。更換期限取決于使用情況，通常至少每3個(gè)月一次。</strong></p><p style="color:#333333;font-family:"font-size:16px;background-color:#FFFFFF;"><strong>3、防護維護由于蠕動(dòng)泵管吸收強腐蝕性試劑，因此應每三個(gè)月更換一次。測量室和反應室應每年至少進(jìn)行一次徹底檢查，清潔和修理。</strong></p><p style="color:#333333;font-family:"font-size:16px;background-color:#FFFFFF;"><strong>4、每日校準除了程序設置的自動(dòng)零周期校準外，在使用，更換試劑或進(jìn)行保護性檢修后，還應校準零點(diǎn)和標準溶液。實(shí)驗室中準備的蒸餾水用作零點(diǎn)校準溶液。校準過(guò)程與測量周期過(guò)程相同，校準后，將保留新零點(diǎn)的參數并校準工作曲線(xiàn)。</strong></p><p style="color:#333333;font-family:"font-size:16px;background-color:#FFFFFF;"><strong>5、出廠(chǎng)參數設置盡管出廠(chǎng)時(shí)已設置了原始工作曲線(xiàn)，但由于使用地點(diǎn)不同，原始工作曲線(xiàn)無(wú)法滿(mǎn)足任何監視場(chǎng)合，因此應定期檢查工作曲線(xiàn)。實(shí)驗室可以準備COD標準溶液以進(jìn)行驗證。校準過(guò)程與測量周期過(guò)程相同。驗證之后，將更改相關(guān)的接口參數以校準工作曲線(xiàn)</strong></p><p style="color:#333333;font-family:"font-size:16px;background-color:#FFFFFF;"><strong>。6、安裝環(huán)境為確保儀器安裝場(chǎng)所的恒溫恒濕，必要時(shí)必須安裝空調及其他供暖，制冷和除濕設施。同時(shí)，使用獨立的穩壓電源。</strong></p><p style="color:#333333;font-family:"font-size:16px;background-color:#FFFFFF;"><strong>7、儀器暫停工作時(shí) 暫時(shí)不使用COD氨氮測定儀時(shí)，應先用蒸餾水徹底清洗并排空，然后依次關(guān)閉進(jìn)，出口閥和電源。重新啟動(dòng)后，應使用新試劑徹底清洗，并校準工作曲線(xiàn)。</strong></p><p></p><p><strong><strong><strong>LB-CNP(B)
