氧氮?dú)浞治鰞x的常見故障及解決方法儀器啟動(dòng)時(shí)顯示。沒有水流。系統(tǒng)分析電流切斷,分析停止。這是水流探測(cè)器不正常,水泵不工作,管道堵塞。將儀器的右面板取下,觀察水流探測(cè)器,用手?jǐn)D壓補(bǔ)水塑料水瓶,發(fā)現(xiàn)水流正常,顯示正常,證明水流探測(cè)器正常,管道暢通。啟動(dòng)循環(huán)水泵,但分析儀顯示沒有水流,此時(shí)可判定水泵不正常。打開水泵轉(zhuǎn)子密封口,啟動(dòng)泵發(fā)現(xiàn)電機(jī)正常運(yùn)轉(zhuǎn),此時(shí)關(guān)閉進(jìn)水,拆下水泵,發(fā)現(xiàn)葉輪脫落。經(jīng)了解,判定是由于外部冷卻水停水,儀器內(nèi)循環(huán)水溫過高(水溫應(yīng)≤70℃),致使葉輪(葉輪材料PVC)熱脹并脫軸。用粘合劑粘合葉輪后再粘于葉輪軸上,待粘合劑凝固后試車,儀器運(yùn)行正常。分析儀,就選上海禹重實(shí)業(yè)有限公司,用戶的信賴之選。
