工作壓力高，容積效率也高，單作用葉片泵易實現(xiàn)流量調(diào)節(jié)，雙作用葉片泵因轉(zhuǎn)子所受徑向液壓力平衡，使用壽命長；但是葉片泵自吸能力差，對油液污染較敏感，葉片容易被雜質(zhì)卡死，工作可靠性差；結(jié)構(gòu)復(fù)雜，對制作精度要求較高，造價高。適用場合：適用于黏度中等的液體。8.旋渦泵旋渦泵特點(diǎn)：旋渦泵結(jié)構(gòu)簡單，流量小，揚(yáng)程高；效率很低（由于液體在流道內(nèi)撞擊損失較大），高不超過45%，通常為15%～40%；大多數(shù)旋渦泵都具有自吸能力，有些旋渦泵還可以抽氣或抽送氣液混合物。適用場合(1)在化學(xué)工業(yè)中輸送酸、堿及其他腐蝕性液體，要求泵具有小流量、高揚(yáng)程、較慢的化學(xué)反應(yīng)速度和較高的耐腐蝕性。由于旋渦泵的工作零件簡單，因此易于實現(xiàn)上述要求。(2)抽送介質(zhì)密度小的液體（如汽油、酒精等）。由于這些液體易于揮發(fā)，因此抽送時多為氣液混輸，如機(jī)場、汽車配油站，甚至于飛機(jī)的加油。旋渦泵能氣液混輸，在上述情況下工作，一般時間短，所以，效率低就不是主要問題了。(3抽送含有氣體的液體，抽送含有高彈性氣體的液體（如丙烷、丁烷等）。抽送吸入管中部分蒸發(fā)的液體。(4)用于小型自動化泵站，農(nóng)業(yè)供水。(5)用于城市公用建設(shè)，如增壓輔助泵、家庭用水等。。薊州區(qū)40DT-A17石家莊工業(yè)泵機(jī)械密封100DT-B40石家莊工業(yè)泵機(jī)械密封。</p><div

為了保證水泵的正常運(yùn)轉(zhuǎn)，一般三個月更換一次機(jī)封，本文就如何更換機(jī)封以及更換機(jī)封的步驟做詳細(xì)說明，供大家參考。工具和原料活動扳手、套筒扳手、一字螺絲刀、一字螺絲刀、沙紙、干凈棉布、潤滑脂維修工作臺、全新機(jī)封一套。換水泵機(jī)械密封的方法：1先裝左邊部分；裝到密封板上2然后機(jī)械密封裝右面那個動環(huán),動環(huán)跟靜環(huán)的密封面要干凈3再裝平鍵和葉輪上好墊片和螺母。安裝前要認(rèn)真檢查集結(jié)密封零件數(shù)量是否足夠，各元件是否有損壞，特別機(jī)械密封件是動、靜環(huán)有無碰傷、裂紋和變形等缺陷。如果有問題，需進(jìn)行修復(fù)或更換新備件。檢查軸套或壓蓋的倒角是否恰當(dāng)，如不符合要求則必須進(jìn)行修整。機(jī)械密封各元件及其有關(guān)的裝配接觸面，在安裝前必須用**或無水酒精清洗干凈。安裝過程中應(yīng)保持清潔，特別是動、靜環(huán)及輔助密封元件應(yīng)無雜質(zhì)、灰塵。動、靜環(huán)表面涂上一層清潔的機(jī)油或透平油。上緊壓蓋應(yīng)在聯(lián)軸器找正后進(jìn)行。螺栓應(yīng)均勻上緊，防止壓蓋斷面偏斜，用塞尺或**工具檢查各點(diǎn)，其誤差不大于005毫米。檢查壓蓋與軸或軸套外徑的配合間隙（及同心度），必須保證四周均勻，用塞尺檢查各點(diǎn)允差不大于010毫米。彈簧壓縮量要按規(guī)定進(jìn)行，不允許有過大或過小的現(xiàn)象。</p><p> 當(dāng)轉(zhuǎn)子按箭頭方向旋轉(zhuǎn)時，與吸氣口相通的空間A的容積是逐漸增大的，正處于吸氣過程。而與排氣口相通的空間C的容積是逐漸縮小的，正處于排氣過程。居中的空間B的容積也是逐漸減小的，正處于壓縮過程。由于空間A的容積是逐漸增大（即膨脹），氣體壓強(qiáng)降低，旋片真空泵的入口處外部氣體壓強(qiáng)大于空間A內(nèi)的壓強(qiáng)，因此將氣體吸入。當(dāng)空間A與吸氣口隔絕時，即轉(zhuǎn)至空間B的位置，氣體開始被壓縮，容積逐漸縮小，與排氣口相通。當(dāng)被壓縮氣體超過排氣壓強(qiáng)時，排氣閥被壓縮氣體推開，氣體穿過油箱內(nèi)的油層排至大氣中。由旋片真空泵的連續(xù)運(yùn)轉(zhuǎn)，達(dá)到連續(xù)抽氣的目的。如果排出的氣體通過氣道而轉(zhuǎn)入另一級（低真空級），由低真空級抽走，再經(jīng)低真空級壓縮后排至大氣中，即組成了雙級旋片真空泵。這時總的壓縮比由兩級來負(fù)擔(dān)，因而提高了極限真空度。工作特點(diǎn)：體積小、重量輕、噪音低；設(shè)有氣鎮(zhèn)閥，可抽除少量水蒸氣；在環(huán)境溫度五攝氏度到四十?dāng)z氏度范圍內(nèi)，進(jìn)氣口壓強(qiáng)小于，被抽氣體相對濕度大于百分之九十時，應(yīng)開氣鎮(zhèn)閥；設(shè)有自動防返油止回閥，啟動方便；進(jìn)氣口連續(xù)暢通大氣運(yùn)轉(zhuǎn)不得超過一分鐘；不適用于抽除對金屬有腐蝕的，對泵油起化學(xué)反應(yīng)的，含有顆粒塵埃的氣體。600DT-A82石家莊工業(yè)泵機(jī)械密封。</p><div
