矿用轴流式主通风机玻璃钢叶片研究

Research on Glass Fiber Reinforced Plastics Blade Used in Main Axial Flow Fans for Mine

针对普通矿用主通风机钢质叶片加工工艺复杂,型线及表面质量难保证,且重量大,影响通风机的空气动力性能和安全运行,提出一种玻璃钢材料叶片,并介绍了其结构方式和制作工艺过程。

Since the manufacture process of steel blade which is used for general mine fan is complicated, it is difficult to obtain the accurate profile and high quality surface. Furthermore, the steel blade is rather heavy. These will influence the aerodynamic performance and safety in service. A glass fiber reinforced plastics blade is proposed and the composition and manufacture process are introduced, too.
