【摘要】 在一种新的可逆式混流转轮全特性的表达方式———对数曲线投影法的基础上 ,利用牛顿 雷伏生法构造了可靠的计算格式。它克服了原有算法的一些缺点 ,算例表明 ,由于新描述方法的单值性和良好的连续性 ,所以该方法精度高 ,速度快 ,适应性好。其泵非起动工况的初值问题 ,要同时对效率、功率和流量进行综合考虑来确定。更多还原

【Abstract】 On the basis of logarithm curve projection method, a new express way of full performances of the reversible mixed flow runner, a reliable calculation method is put forward. This calculation method overcomes some shortcomings existing in the original calculation method. The practice shows that due to its features of single value and good continuity, such new method has advantages of high accuracy, quick calculation speed and good adaptability. The non starting working condition of the pump shall be determined by a comprehensive consideration on its efficiency, power and discharge.更多还原
