摘要
本文从流体力学的一般原理出发,运用相似理论的方程分析法,系统地分析泵装置动力特性、空蚀特性、飞逸特性的相似模拟方法,阐述了相似准则之间的关系、参数换算比尺及模型试验要点,推导得出了泵及泵装置效率换算新的计算公式,并给出水力效率换算系数的理论表达。
Based on hydromechanics theory, the similitude methods for the model test of pump set characteristics, cavitation characteristics and runaway speed characteristics are analyzed by applying the equation of analytical method with analogy theory. The similarity criteria of parameters scaling laws and key points between the model experiments and the prototype experiments are set forth. The new efficiency formulas are put forward between model pump set and prototype pump set. The theoretical expression of the coefficiente among hydraulic efficiency conversion formula is also presented.
