因?yàn)槌隹诠?jié)流會造成液體的過熱或汽化，所以噴氣發(fā)動機(jī)燃料管道泵常采用入口節(jié)流。在很小的流量下，這些泵的葉輪只是部分地充滿液體，因此，輸入功率和溫升約為出口節(jié)流時(shí)葉輪充分運(yùn)轉(zhuǎn)位的1/30凝結(jié)水泵的流量通常采用淹沒深度來控制7，這相當(dāng)于入口節(jié)流。特殊的設(shè)計(jì)可把這些泵的汽蝕損壞降低到無足輕重的程度，但能級也變得相當(dāng)?shù)汀?.旁通調(diào)節(jié)從管道泵的排出管路可以分流出全部或部分流量，經(jīng)過旁路管引到泵的口或其它的適當(dāng)點(diǎn)。旁路中可裝一個(gè)或多個(gè)流量孔板和合適的控制閥。計(jì)量旁路通常用于減小鍋爐給水泵的流量，主要是為了防止過熱。如果旁路旋槳泵多余的流量，用以取代出口節(jié)流，則可節(jié)省相當(dāng)大的功率。4.轉(zhuǎn)速調(diào)節(jié)采用這種方法調(diào)節(jié)流量時(shí)。

In order to make its sewage self-priming pump suction pipe will not appear the phenomenon of gas accumulation, sewage self-suction pump suction pipe requirements of the fewer elbow the better, up to one elbow is appropriate, suction water to the pump import should be arranged in the way of slope upward to avoid the phenomenon of accumulation of gas. In order to ensure that the sewage self-suction pump suction pipe compleby sealed non-leaking phenomenon of sewage self-priming pump suction pipe should not be increased and reduced. Sewage self-suction pump suction pipe Increased after the pipeline will have a large number of gas is not easy to clean, sewage self-suction pump self-suction exhaust time after the pump body inside the water will change heat pump body hot, will lead to sewage self-suction pump can not absorb liquid, sewage self-suction pump suction pipe shrinkage, Because the export is larger than the import and the discharge of large flow of traffic caused by the import flow can not keep up with the export flow, so there will be a failure. Sewage self-priming pump suction pipeline requirements of quality and material requirements are very strict. Therefore, water suction pipes usually use steel tubes or PVC tubes.
