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

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).
