摘要
通过增大叶轮直径和叶片出口安装角的方法对风机性能的影响进行计算和分析 ,完成了对瓦斯气体送风机的改造 ,增大了运行点流量和全压 ,经过现场性能测试 。
The calculation and analysis are carried out on the effect of fan performance by increasing impeller diameter and blade mounting angle. The transformation of gas exhaust fan is completed. The flow rate and total pressure of operating point is increased. It is proved that the method is practical by performance test on site.
