discharge blade 中文意思是什麼
discharge blade
解釋
排出葉片-
Mainly, the type of pump in the large - scale irrigation and drainage pumping station in our country is adjustable - blade propeller pump. we can regulate the pump ' s blade mounting angle following the variation of water level at the inlet and outlet of the station in order to control the discharge of pump, we also determine the number of running machines with machine ' s optimal combination. so we can reduce its energy consumption, and make it optimally and economically run
我國大部分大型電力排灌站所安裝的泵都為可調節葉片的軸流泵，這一有利條件使我們可以根據排灌站進、出口水位的變化來調節水泵的葉片角度，控制水泵的流量，併合理的確定開機臺數，通過機組間的優化組合，使整個泵站的能耗最少，達到整體最優、經濟運行的目的。 -
The method of prediction the discharge coefficients of film cooling holes on the turbine blade suggested by d. a. rowbury et. al has been improved in this paper to fit the computations in the cases of low pressure ratios and the holes in leading edge region especially. the effects of external cross - flow, hole geometry and reynolds number in the hole were taken into account. an additive loss coefficient method is subsequently applied to the test data in order to assess the effect of the external cross - flow
Rowbury等提出的流量系數工程演算法進行了改進，計算結果和實驗數據的比較表明改進后的新模型使低吹風比和前緣駐點附近流量系數的計算得到了明顯的改進，而在高吹風比下仍能保持與實驗數據相符，這種演算法有可能成為低壓比情況下型面氣膜冷卻的一種通用設計方法。 -
When the water head and the flow are given, we can regulate the pump ' s blade mounting angle to control the discharge of pump in this pumping station that contains only one type of pump. we also can determine the number of running machines with machine ' s optimal combination. so we can reduce its energy consumption, and make it run optimally and economically
當水頭和抽水流量給定時，這類泵型單一的泵站，可以通過調節水泵的葉片角度，控制水泵的流量，併合理確定開機臺數，通過機組間的優化組合，使整個泵站的能耗最少，達到整體最優、經濟運行的目的。 -
