柴油機雙吸泵@海港柴油機雙吸泵@柴油機雙吸泵300口徑
能用電動機的就不用柴油機或汽油機,有條件用三相異步電動機的不用單相異步電動機。中開泵(中開式循環(huán))又稱之為單級雙吸式離心泵,中開雙吸泵,其主要特征為輸送介質(zhì)的流量大,中開泵運行的工作原理:葉輪安裝在泵殼內(nèi),并緊固在泵軸上,泵軸由電機直接帶動。泵殼有一液體與管連接。液體經(jīng)底閥和管進入泵內(nèi)。泵殼上的液體排出口與排出管連接。當(dāng)泵的轉(zhuǎn)速一定時,其壓頭,流量與葉輪直徑有關(guān)。今天我們來說說臥式中開泵與立式中開泵有哪些區(qū)別。臥式中開泵與立式中開泵的區(qū)別主要有:1,外觀形式不同,立式泵是立著的而臥式泵是橫臥著。連接形式不同,立式泵自下而上疊加連接,臥式泵縱向排列于底座上。占地空間不同,立式泵占地面積小而臥式泵占用面積大。
本系列泵是單級、雙吸、水平中開式離心泵,適用于汲送清水和無腐蝕性的液體。介質(zhì)溫度80℃。軸承體通人冷卻水后,可輸送130℃以下的熱水。改變密封環(huán)、軸套和葉輪的材質(zhì),可以輸送含有泥沙的渾水。改變承壓零件的材質(zhì),可以提高泵的進口壓力.泵的軸封一般采用軟填料密封,如有特殊要求,也可改裝機械密封。從電機方向看泵,泵為逆時針旋轉(zhuǎn),按用戶要求,也可改為順時針旋轉(zhuǎn)。jdhuiquan4.13

方便現(xiàn)場安裝。(1)結(jié)構(gòu)上縮短轉(zhuǎn)子部件軸向尺寸,軸的鋼性更好,運行更穩(wěn)定可靠。設(shè)有泵體字符封環(huán),而葉輪密封環(huán)為可選用件。密封環(huán)磨損后可以更換,減少了運行維護費用。S系列中開泵裝配與拆卸1,裝配轉(zhuǎn)子部件:依次將葉輪,軸套,軸套螺母,填料套,填料環(huán),填料壓蓋,擋水圈,軸承部件裝在泵軸上,并套上雙吸密封環(huán),然后裝上聯(lián)軸器。將轉(zhuǎn)子部件裝在泵體上,調(diào)整葉輪的軸向位暈到兩側(cè)雙吸密封環(huán)的中間加以固定,將軸承體壓蓋同固定螺釘緊固。裝上填料,放好中開面紙墊,蓋上泵蓋打緊螺尾柱銷后,擰緊泵蓋螺母,zui后裝上墳料壓蓋。但不要將填料壓得太緊,填料過緊會使軸套發(fā)熱,耗費功率較大,也不要壓得太松,過松會使液體滲漏大,水泵效率降低。
根據(jù)水泵行業(yè)規(guī)定,Sh型與S型兩大系列中開泵并存,直至統(tǒng)一設(shè)計出新型泵代替這兩個系列時為止。本產(chǎn)品主要用于工廠、礦山、城市、電站給水農(nóng)用排澇灌溉、各種水利工程用泵和采暖空調(diào)系統(tǒng)等場合
[二]性能范圍:
流量Q112m3/h-6460m3/h,揚程H9m-140m,允許進口壓力≤0.3Mpa(用戶在訂貨時須標(biāo)明進口壓力值)。
