horsepower varies directly with the cube of impeller diameter and speed.
说到了叶轮直接和泵的转速与流量,扬程,功率之间的关系。
pump lift pump depends on the size of the structure (such as the impeller diameter the size of the blades bend, and so on, the speed.
泵的扬程大小取决于泵的结构(如叶轮直径的大小,叶片的弯曲情况等、转速。
there is a relationship between the trim exponents and impeller diameter ratio, namely the exponents vary with the ratio.
叶轮切割指数与直径比的确存在着某种关系,也就是切割指数随着切割后的直径比的变化而变化。
this thesis introduces the design of impeller diameter measuring mechanism in robot flexible polishing machine tool on the basis of rack-and-pinion linear diploid mechanism theory.
