摘要
利用叶片式水力机械内特性解析理论,建立了混流式水泵水轮机全特性曲线的数学表达式。对全特性曲线上的特征工况点进行了分析,结合统计数据给出了绘制混流式水轮机全特性曲线的方法。以实例说明这一方法的工程实用性。
The mathematical expressions of the whole characteristic curve of pump- turbines are established based on the internal character analysis theory of hydraulic turbomachines.The special condition points on the characteristic curve are analysed and a theoretical drawing method for the whole characteristic curve of the mixed- flow pump-turbines is derived using statistical data.An example shows that the method is practical in the engineering practice.
