摘要
介绍了东方汽轮机厂从国外引进的两种动叶片———平衡动叶和高负荷动叶。对这两种不同动叶叶栅的气动特性进行了试验研究。结果表明:高负荷动叶不仅负荷系数高,而且损失系数小,特别在根部截面,损失系数比传统动叶片降低了50%以上。
Two kinds of rotating blades-balanced and high load rotating blades licensed from abroad by Dongfang Steam Turbine Works are being presented. Experimental study on the aerodynamic characteristics of these two different kinds of the rotating blades has been carried out. Results show that the high load rotating blades not only have a higher loading coefficient, but also a lower loss coefficient. Especially at root section, the loss coefficient is lower than that of traditional rotating blades by more than 50%.
