design head meaning in Chinese
设计水头
设计压头
Examples
- When the design head was 37
8万千瓦较为合理。 - The results showed that considering the general performance of turbine and the discharge capacity of runner hl240 - lj - 420 , when the design head was 36 . 2m , the electricity generated by turbine generator increases to 4 . 8 million kw , which was relatively reasonable
结果表明：考虑到水轮机的综合性能和hl240thj一10流道的过流能力，在设计水头为36 2米时，水轮机发电机出力增容到4 - ( 2 ) retrofitted the small turbine of tai pin shao hydropower station in this paper . the results indicated that given the unchanged channels of the original runner hl240 - lj - 120 and satisfied cavitation condition and stability requirement , the electricity generated by the turbine generator increased from 3000kw to 3600kw when the design head was 36 . 2m , which arrived at the expectant objective
( 2 )对太平哨电厂的小机进行了改造，在不改变原hl240 - lj - 120流道并满足气蚀和稳定性要求，在设计水头为36 . 2米时，水轮机发电机出力由原来的3000千瓦增容到3600万千瓦，达到了预期目标。 - Abstract : the effect of turbine characteristic on stable sectional area of surge tank can be expressed by the synthetic characteristic coefficient of turbine , it shows the effect of turbine efficiency . based on the analysis on the variation of the characteristic curve for middle or high specific speed turbine , this paper demonstrates that the largest stable sectional area of surge tank is not dependent on the lowest water head of hydroelectric plant but the design head
文摘:通过理论推导，研究了水轮机综合特性系数对调压室稳定断面的影响，即水轮机运行中不同工况点效率的相对变化对调压室稳定断面的影响.得出了最危险的调压室稳定断面取决于设计水头，并通过实例得到验证
