First super - low specific - speed centrifugal pump has a long and narrow flow passage for its high head and low capacity, and the power absorbed by disc friction is too high, so the efficiency is very low ; secondly the diffusion of flow passage is so high, that the reserved flow often emerges at the inlet and outlet of impeller. therefore the h ~ q characteristic curve is often hump - shaped, and at the low - capacity operating condition the instability often occurs ; thirdly the centrifugal pump at high - capacity operating condition is easy to overload because the n ~ q curve appears a rising trend
首先由於它的揚程較高、流量較小，所以它的流道狹長，圓盤摩擦損失較大，效率相對較低；其次由於它的流道擴散較嚴重，易在葉片進口產生迴流和在出口產生脫流，揚程流量特性曲線易出現駝峰，在小流量工況下易產生不穩定現象；第三，由於其功率流量曲線呈現上升趨勢，在大流量區運行時電機易過載。 -
Very low workload is generally associated with boredom and decreased effectiveness in monitoring performance, while very high workload is associated with information overload that results in decreased efficiency of information processing, which can lead to loss of situational awareness
工作壓力總是會伴隨著懈怠和低效率，而過高的工作壓力則伴隨著信息超載，引起信息處理的低效、無序，從而導致判斷上的失誤。
