駝載
英文
piggyback-
The camels were too done to carry our weight.
駱駝已疲倦得無法載我們。It is the last straw that breaks the camel ' s back
駱駝負載過重時，加根草也能把它壓倒。In present thesis, the actual design theories and methods for super - low specific - speed pump are introduced first, including " the increased flowrate design method ", " the method of anti - hump on h ~ q characteristic curve ", " non - overload design method ", " the design method of complex impeller " and so on. according to these methods, 5 types of impeller have been designed
論文首先對極低比轉數離心泵的現行設計理論和設計方法作了介紹，包括加大流量設計法、減小或消除揚程曲線駝峰的途徑、無過載設計及復合葉輪設計法等，並按照這些方法設計了五種葉輪。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。Additionally, while supporting the day - to - day operations of american and chinese airmen, and maintaining china ' s fragile life - line to the allied world, another 1, 500 american and chinese airmen lost their lives while shepherding overloaded transport planes along the notorious " hump " air route that led across the daunting himalayan mountain range
此外，在那些支持日常軍事行動的中美兩國空軍和維持著中國與盟軍連接的脆弱的生命線中，在指導駕駛那些超載的運輸機飛越險惡的喜馬拉雅山脈的「駝峰空運」時，另外1500名中美兩國飛行員陣亡了。The merchant decided to use camels to carry his goods across the desert
