id="p2jgi33" class="box"><p><p> 離心泵是靠葉輪離心力形成真空的吸力把水提起，所以，離心泵啟動時，必須先把閘閥關閉，灌水。水位超過葉輪部位以上，排出離心泵中的空氣，才可啟動。啟動后，葉輪周圍形成真空，把水向上吸，其閘閥可自動打開，把水提起。因此，必須先閉閘閥。 </p> <p> 振動分析 </p> <p> 離心泵的轉子不平衡與不對中。這個問題在離心泵的振動問題中所占比例較大，約為80%的比例。造成離心泵轉子不平衡的因素：材料阻止不均勻、零件結構不合格，造成轉子質量中心線與轉軸中心線不重合產生偏心據(jù)形成的不平衡。校正離心泵的轉子不平衡又可分為兩。靜平衡與動平衡：一般也稱為單面平衡和雙面平衡，上海耐堿離心泵功率。其區(qū)別就是：單面平衡是在一個校正面進行校正平衡，上海耐堿離心泵功率，上海耐堿離心泵功率，而雙面平衡是在兩個校正面上進行校正。離心泵廠家，歡迎您的來電——靖江市瑞鑫泵業(yè)有限公司。上海耐堿離心泵功率</p><div

使液體自動的流入泵的入口處。當入口處的真空度達到一定程度時，即使在常溫下，入口處的液體也能汽化而產生氣泡，這些氣泡隨液體一起進入葉輪。在離心力的作用下液體壓力逐漸升高，氣泡便凝結成液體而消失，此刻周圍液體迅速來補充，從而發(fā)生了猛烈的碰撞，瞬間產生很強的水錘現(xiàn)象，打擊葉輪表面，便產生機械腐蝕。一方面葉輪受到損害，同時發(fā)出響聲，泵有振動，流量減小，揚程下降，效率降低等，這種現(xiàn)象叫氣蝕現(xiàn)象。離心泵的主要部件有哪些？.離心泵的主要部件有葉輪、泵體、軸、軸承、吸入室、壓出室、密封裝置和平衡裝置等。9、離心泵的葉輪有什么作用？離心泵的葉輪是對葉輪作功的部件。葉輪在泵體內有泵軸的帶動下高速旋轉，使流過泵的液體獲得能量。也就是說通過葉輪的高速旋轉把機械能傳給液體，使液體才能獲得很高的動壓能。10、離心泵的葉輪是由哪些部件組成？離心泵的葉輪是由前輪板、后輪板、葉片和輪轂四部分組成的。它分為閉式葉輪、半開式葉輪和開式葉輪。11、離心泵的軸向力是怎樣產生的？（1）葉輪兩側的液體壓力不對稱o（2）液體從葉輪入口流到出口，因流體的流動方向由軸向變?yōu)閺较?，所以在葉輪上產生反作用力。<br>上海耐堿離心泵功率</p><p
