摘要
效率是衡量风机运行经济性的一项主要指标 ,本文结合对旋式风机的内流损失 ,提出了一种效率估算方法 ,经实践验证 ,能有效地预测对旋风机的效率。
Efficiency is an important parameter for evaluating the economy of fan. In this paper, A method for estimating the efficiency of fan is presented which takes into account the internal flow loss of fan. The predicting method is proved by test to be valid for predicting the efficiency of counter rotating fans.
