隔膜計量泵日常故障分析及具體解決方案解讀

鄭州巴特作為國內(nèi)專業(yè)計量泵生產(chǎn)企業(yè)，擁有數(shù)十年的熔體計量泵生產(chǎn)經(jīng)驗(yàn)，提供的新型計量泵設(shè)備包括：隔膜計量泵、柱塞式計量泵等。隔膜計量泵目前主要應(yīng)用于石油工業(yè)、天然氣開、采、化工、煉油、、食品、制藥、科研、印染、造紙、水處理工業(yè)等領(lǐng)域。
隔膜計量泵在實(shí)際應(yīng)用中出現(xiàn)一些故障，需要根據(jù)不同的工況具有針對性的處理。隔膜計量泵在實(shí)際應(yīng)用中常見故障有：一是隔膜失效或單向閥堵塞，檢查單向閥是否堵塞或外層隔膜是否失效，解決單向閥堵塞的方法是將泵入口管從配料罐底引出改為從罐壁引出，將管線高度提高，使雜質(zhì)沉淀在罐底，然后定期排掉；二是入口單向閥損壞，失效原因主要包括閥芯與閥座配合不好、閥體密封環(huán)失效、閥彈簧失效或其預(yù)緊力不當(dāng)；三是安全泄壓閥設(shè)定值太低，要重新設(shè)定泄壓閥的壓力；四是減速箱失效。隔膜計量泵常見故障及原因：一是驅(qū)動端故障表現(xiàn)為曲軸箱溫度過高、振動大且有雜音，原因是曲軸箱油溫過高；二是液體端故障表現(xiàn)為流量及壓力波動大、過計量、無流量排量少、計量精度降低等。
在熔體計量泵使用過程中，熔體計量泵的維護(hù)與發(fā)生故障及時檢修非常重要。如進(jìn)口、出口閥組的維護(hù)，閥組易損件每5000小時更換一次，若輸送介質(zhì)無顆粒雜質(zhì)、高濃度等影響，該閥組在工作正常情況下不必拆卸檢查;需要時只拆掉吸排管壓板，閥組即全部松開。要注意保護(hù)閥線處不得碰撞、損壞。安裝時依序安裝，注意閥座與墊片的位置是否正確、到位，否則計量泵將不能正常工作。影響熔體計量泵產(chǎn)生故障的因素較多，所以常見故障本身比較復(fù)雜，只能在實(shí)踐中不斷總結(jié)經(jīng)驗(yàn)和改進(jìn)技術(shù)，通過長期的技術(shù)進(jìn)步和改造，掌握隔膜計量泵的機(jī)理，分析和判斷發(fā)生故障的原因，降低實(shí)際生產(chǎn)和應(yīng)用中的損失，提高隔膜計量泵生產(chǎn)的經(jīng)濟(jì)性和實(shí)際的應(yīng)用性。詳細(xì)您可以咨詢我們24小時的服務(wù)熱線：0371-67993077
