1.出口節流對于低,中比轉數泵而言,這是一種普遍和低廉的流量調節方法。通常這種方法也僅限于在低,中比轉數泵上使用。部分關閉出口管路上任意形式的閥門均會增大系統壓頭,因此系統壓頭曲線將在較小的流量下與管道泵壓頭曲線相交。出口節流使操作點移動到較低的效率點處,并在節流閥處有功率損失。這對大型的泵裝置可能很重要。結論:當系統油壓力達到’安全閥開啟壓力時而投資較高的調節方法可能在經濟性上更具吸引力。節流至關死點可能引起泵內流體過熱,可以用旁路來維持必要的流量,或用不同的調節手段。這對前面所提及的處理熱水或揮發性液體的泵而言是非常重要的。2.口節流如果有充足的NPSH可以利用,那么在管路可以通過節流節省一些功率。

ISG立式管道離心泵 產品特點:
1、 泵為立式結構,進出口徑相同,且位于同一中心線上,可象閥門一樣安裝于管路之中,外形緊湊美觀,占地面積小,建筑投入低,如加上防護罩則可置于戶外使用。
2、 葉輪直接安裝在電機的加長軸上,軸向尺寸短,結構緊湊,泵與電機軸承配置合理,能有效地平衡泵運轉產生的徑向和軸向負荷,從而保證了泵的運行平穩,震動噪音很低。
3、 軸封采用機械密封或機械密封組合,采用進口鈦合金密封環、中型耐高溫機械密封和采用硬質合金材質,耐磨密封,能有效地增長機械密封的使用壽命。
4、 安裝檢修方便,無需拆動管路系統,只要卸下泵聯體座螺母即可抽出全部轉子部件。
5、 可根據使用要求即流量和揚程的需要采用泵的串、并聯運行方式。
6、 可根據管路布置的要求采用泵的豎式和橫式安裝。

This will also lead to sewage self-suction pump can not absorb water phenomenon. If the sewage self-priming pump suction pipe to have a pipe into 2 pipes, we should pay special attention to the loss of 2 pipes is relatively large, should be based on the maximum flow rate of the pipeline to choose the corresponding sewage self-suction pump suction pipe, from the understanding of the company can consult the relevant experts, We will calculate the corresponding pipe size for you according to the flow rate of the relevant sewage self-priming pump you need, so as not to avoid the flow of sewage self-priming pump to meet the design standards, to prevent unnecessary trouble. Sewage self-suction pump suction pipe requirements and sewage self-suction pump suction pipe can not be inserted into the pool depth is too shallow. Self-suction refers to the pipe in the tube without filling the liquid (but the pump body must have enough liquid) to start the pump, the pump itself can automatically remove the gas in the tube, and then into normal operation, the pump in the initial start must be filled with enough liquid, after the start of the liquid retained in the pump to ensure that the pump can start again. The self-priming time of the sewage self-priming pump refers to the pump cleaning liquid at room temperature, the installation height for the allowable vacuum () minus 0.5, from the pump start to the pressure stability of the shortest time required, that is, the pump drain despite the internal air required time. For centrifugal sewage self-priming pump, the pipe length between the suction surface and the pump inlet (Tube hole diameter).
