摘　　要：针对某玻璃厂钢化系统BT炉风机存在的运行效率低,噪声大等问题,提出了风机优化方向。首先分析了用户使用的小流量高压风机的流场及气动噪声,在此基础上,重新设计了后弯式高效低噪风机,并分析了其气动性能和气动噪声。研究表明:优化后的风机性能曲线平坦,消除风机喘振现象,确保风机运行的安全性。风机效率和压力均大幅度提高,噪声降低。改造后风机节能率达到24.7%,单台风机年度节电量为473 000kW·h,取得较好的经济效益和社会效益。The BT furnace fan in Glass factory tempering system has the problem of running in low efficiency and big noise.After analyzing the flow rate and noise of the small flow rate and high pressure fan, the backward fan with high efficiency and lose noise is redesigned. The performance and aerodynamic noise of the new fan are calculated. The result shows the new fan performance curve is flat without surge, the efficiency,noise and pressure of fan has improved. The saving energy rate is about24.7%, the annual electricity save up to 473 000 kW·h.
