離心泵是利用葉輪旋轉(zhuǎn)而使水發(fā)生離心運(yùn)動(dòng)來(lái)工作的。水泵在啟動(dòng)前，必須使泵殼和吸水管內(nèi)充滿水，然后啟動(dòng)電機(jī)，使泵軸帶動(dòng)葉輪和水做高速旋轉(zhuǎn)運(yùn)動(dòng)，水發(fā)生離心運(yùn)動(dòng)，被甩向葉輪外緣，經(jīng)蝸形泵殼的流道流入水泵的壓水管路。 </p> <p> 離心泵的基本構(gòu)造是由六部分組成的分別是葉輪，泵體，江蘇污水離心泵介質(zhì)，泵軸，軸承，密封環(huán)，填料函。 </p> <p> 葉輪是離心泵的主要部分，江蘇污水離心泵介質(zhì)，它轉(zhuǎn)速高出力大，江蘇污水離心泵介質(zhì)，葉輪上的葉片又起到主要作用，葉輪在裝配前要通過(guò)靜平衡實(shí)驗(yàn)。葉輪上的內(nèi)外表面要求光滑，以減少水流的摩擦損失。離心泵廠家歡迎您來(lái)咨詢——靖江市瑞鑫泵業(yè)有限公司。江蘇污水離心泵介質(zhì)</p><div

實(shí)際使用效果表明，密封元件失效**多的部位是動(dòng)，靜環(huán)的端面，離心泵機(jī)封動(dòng)，靜環(huán)端面出現(xiàn)龜裂是常見的失效現(xiàn)象，主要原因有： </p> <p> 安裝時(shí)密封面間隙過(guò)大，沖洗液來(lái)不及帶走摩擦副產(chǎn)生的熱量；沖洗液從密封面間隙中漏走，造成端面過(guò)熱而損壞。 </p> <p> 液體介質(zhì)汽化膨脹，使兩端面受汽化膨脹力而分開，當(dāng)兩密封面用力貼合時(shí)，破壞潤(rùn)滑膜從而造成端面表面過(guò)熱。 </p> <p> 液體介質(zhì)潤(rùn)滑性較差，加之操作壓力過(guò)載，兩密封面追蹤轉(zhuǎn)動(dòng)不同步。例如高轉(zhuǎn)速泵轉(zhuǎn)速為20445r/min，密封面中心直徑為7cm，泵運(yùn)轉(zhuǎn)后其線速度高達(dá)75 m/s，當(dāng)有一個(gè)密封面滯后不能追蹤旋轉(zhuǎn)，瞬時(shí)高溫造成密封面損壞。 </p> <p>
