摘要
鉴于传统观点认为离心叶轮弧前盘优于锥前盘的情况,文章对3台离心通风机分别采用锥前盘和弧前盘进行整机性能数值预估对比,结果表明,锥前盘风机可以达到弧前盘风机的高性能,对锥前盘有了新的认识。
It has been noted for a long time that the front arc plate of impeller is better than the front taper plate.In this paper,the estimation and comparison of performance values are carried out on three centrifugal fans with the front arc plate and the front taper plate respectively.The results show that the fan with front taper plate can reach the high performances of the fan with front arc plate,which makes a fresh cognition about front taper plate.
