style="text-indent:25px">真空泵使用說明：1、關(guān)閉泵上方的閥門。2、有冷卻水的泵接通冷卻水。3、近規(guī)定轉(zhuǎn)向手盤皮帶輪數(shù)圈，把泵腔內(nèi)的油排入油箱內(nèi)，確保啟動不易噴油。（特別在冬季，油粘大，啟動負(fù)荷大，故請注意）。4、啟動電動機，泵開動運轉(zhuǎn)，觀察油窗，檢查油位。油位應(yīng)在油標(biāo)中心，油位偏高，會造成噴油；油位偏低，會造成潤滑不良，泵極限壓力達(dá)不到出廠指標(biāo)。加油、放油位置詳見泵指示牌。緩慢打開泵上方的閥門，系統(tǒng)開始工作。泵不工作時，油窗內(nèi)幾乎看不到油，都進(jìn)入泵體內(nèi)，油位以泵運轉(zhuǎn)時為準(zhǔn)。5、冷卻水的進(jìn)水溫度以不超過30℃為宜，進(jìn)出水溫差以不超過3℃為宜。6、當(dāng)環(huán)境溫度低于5℃時，應(yīng)將泵油放出加熱到15-30℃后加入泵內(nèi)啟動工作。7、泵溫以油溫減去環(huán)境溫度不超過40℃為宜，否則應(yīng)加強通風(fēng)散熱或增加冷卻水流量。實驗用真空泵生產(chǎn)供應(yīng)真空泵通電試運轉(zhuǎn)時要確認(rèn)真空泵轉(zhuǎn)向符合規(guī)定方向方可投入使用。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="實驗用真空泵生產(chǎn)供應(yīng),真空泵"

style="text-indent:25px">真空泵的維護(hù)和保養(yǎng)：1、經(jīng)常檢查油位位置，不符合規(guī)定時須調(diào)整使之符合要求。以泵運轉(zhuǎn)時，油位到油標(biāo)中心為準(zhǔn)。2、經(jīng)常檢查油質(zhì)情況，發(fā)現(xiàn)油變質(zhì)應(yīng)及時更換新油，確保泵工作正常。3、換油期限按實際使用條件和能否滿足性能要求等情況考慮，由用戶酌情決定。一般新泵，抽除清潔干燥的氣體時，建議在工作100小時左右換油一次。待油中看不到黑色金屬粉末后，以后可適當(dāng)延長換油期限。4、一般情況下，泵工作2000小時后應(yīng)進(jìn)行檢修，檢查桷膠密封件老化程度，檢查排氣閥片是否開裂，清理沉淀在閥片及排氣閥座上的污物。清洗整個泵腔內(nèi)的零件，如轉(zhuǎn)子、旋片、彈簧等。一般用汽油清洗，并烘干。對橡膠件類清洗后用干布擦干即可。清洗裝配時應(yīng)輕拿輕放小心碰傷。</p><p style="text-indent:25px">真空泵泵在應(yīng)用場合的布置攻略要注意什么？露天布置一般將泵集中布置在管廊下方或側(cè)面，也可以布置在被抽吸設(shè)備附近，主要優(yōu)點是通風(fēng)良好，操作和堆修方便。若泵布置在管廊下方時，泵出口中心線應(yīng)對齊，距管廊柱中心線0.6m。半露天布置的泵適用于多雨地區(qū)，一般在管廊下方布置泵，在管道上部設(shè)頂棚?；?qū)⒈貌贾迷诳蚣艿南聦拥孛嫔?，以框架平臺作為頂棚。根據(jù)泵的布置要求，將泵布置成單排、雙排或多排。室內(nèi)布置的泵適用于寒冷或多風(fēng)沙地區(qū)，以及工藝有特殊要求的場合。真空泵特點：在較寬的壓力范圍內(nèi)有較大的抽速。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="實驗用真空泵生產(chǎn)供應(yīng),真空泵" src="https://tyunfile.71360.com/UploadFile/shjiuxinjd/637357851697490234/612225.png"></div><p style="text-indent:25px">真空泵吸入的如果是腐蝕性氣體會怎么樣？會與油發(fā)生化學(xué)反應(yīng)，腐蝕泵內(nèi)零件；吸入空氣中往往含有水汽冷凝水，引起真空泵油的乳化并使金屬腐蝕，所以要求具有良好的抗腐蝕和抗乳化性。主要要求真空泵中不攜帶輕質(zhì)組分，以免影響油品的飽和蒸氣壓。極限壓力是真空泵油重要的使用性能指標(biāo)以了解在較低真空極限壓力下真空泵的極限壓力。真空泵用于機組啟動時抽真空，正常運行時用于抽出凝汽器中未凝結(jié)的氣體。該泵配備電機160kW，轉(zhuǎn)速590r/min，額定電流330A，電壓380V，B級絕緣，正常運行時電流220～230A。每年夏季，電機溫度都會超限，被迫加裝臨時冷卻風(fēng)機，但收效不大。電機長期高溫運行會造成絕緣老化，縮短其使用壽命。真空泵換油時應(yīng)將泵體內(nèi)使用過的油品排盡，將新油倒入后緩緩轉(zhuǎn)動泵軸。石家莊一體式真空泵</p><p style="text-indent:25px">真空泵特點：泵腔內(nèi)無壓縮，無排氣閥。實驗用真空泵生產(chǎn)供應(yīng)</p><p style="text-indent:25px">真空泵安裝在連接管路中，用戶可以在泵進(jìn)氣口上方安裝閥門及真空計，隨時可檢查泵的極限壓力。按電動機標(biāo)牌規(guī)定連接電源，并接地線和安裝合適規(guī)格的熔斷器及熱繼電器。泵通電試運轉(zhuǎn)時，須取下電機皮帶，確認(rèn)泵轉(zhuǎn)向符合規(guī)定方向方可投入使用，以防泵反轉(zhuǎn)噴油。（轉(zhuǎn)向按防護(hù)罩指示方向）對于有冷卻水的泵，按規(guī)定接通冷卻水。如泵口安裝電磁閥時，閥與泵應(yīng)同時動作。當(dāng)泵排出氣體影響工作環(huán)境時，可在排氣口裝接管道引離或裝接油霧過濾器。實驗用真空泵生產(chǎn)供應(yīng)</p></p><br
