14.5455px;">需要強調指出的是，若在離心泵啟動前沒向泵殼內灌滿被輸送的液體，由于空氣密度低，葉輪旋轉后產生的離心力小，葉輪中心區不足以形成吸入貯槽內液體的低壓，因而雖啟動離心泵也不能輸送液體。這表明離心泵無自吸能力，此現象稱為氣縛。吸入管路安裝單向底閥是為了防止啟動前灌入泵殼內的液體從殼內流出?？諝鈴奈牍艿肋M到泵殼中都會造成氣縛。</span></p><p

style="margin: 0px; padding: 0px; font-size: 14.5455px;">　　閉式和半閉式葉輪在運轉時，離開葉輪的一部分高壓液體可漏入葉輪與泵殼之間的空腔中，因葉輪前側液體吸入口處壓強低，故液體作用于葉輪前、后側的壓力不等，便產生了指向葉輪吸入口側的軸向推力。該力推動葉輪向吸入口側移動，引起葉輪和泵殼接觸處的摩損，嚴重時造成泵的振動，破壞泵的正常操作。在葉輪后蓋板上鉆若干個小孔，可減少葉輪兩側的壓力差，從而減輕了軸向推力的不利影響，但同時也降低了泵的效率。這些小孔稱為平衡孔。</span></p><p

14.5455px;">　　(2)按吸液方式不同可將葉輪分為單吸式與雙吸式兩種，單吸式葉輪結構簡單，液體只能從一側吸入。雙吸式葉輪可同時從葉輪兩側對稱地吸入液體，它不僅具有較大的吸液能力，而且基本上消除了軸向推力。</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; color: rgb(68, 68,

14.5455px;">　　為了減少離開葉輪的液體直接進入泵殼時因沖擊而引起的能量損失，在葉輪與泵殼之間有時裝置一個固定不動而帶有葉片的導輪。導輪中的葉片使進入泵殼的液體逐漸轉向而且流道連續擴大，使部分動能有效地轉換為靜壓能。多級離心泵通常均安裝導輪。</span></p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px;
