对旋轴流风机毕业设计说明书.doc

本文主要论述了风机的分类、应用领域及国内外的发展状况。针对局部通风机进行了结构设计。该风机由集流器、叶轮、电机、风筒、扩散器等部分组成。风机的两级叶轮分别用两个相同型号的隔爆电机驱动,可根据需要来调节风压和流量。在风机的入口和出口处采用了外包复式消声结构来降低噪声。、流量大、风压高的优点,非常适合井下巷道的长距离通风.
本文主要的研究内容包括;(1)由给定设计参数进行了风机的第一、二级叶轮的参数计算。(2)应用等环量方法进行空气动力计算。(3)风机各部分的结构设计(4)流线罩与扩散器的尺寸参数计算。(5)风机噪声的控制。

Abstract
This article mainly the air blower classification, the application domain and the domestic and foreign development condition. Has carried on the structural design to the partial ventilator. This air blower by the slip ring, the impeller, the electrical motor, the air duct, the fan diffuser and so on partially posed. Two same model type motors Separately drivend two levels of impellers. The article can according to need to adjust the wind pressure and the current capacity. The air blower entrance and the export have wrapped the noise elimination material may the noise reduction . This air blower mainly applies to the mine pit face of heading Partial ventilates. It has the young volume, flux is big, the wind pressure higher merit. extremely suits the mine shaft tunnel the long distance to ventilate
This article main research content includes: (1)By assigned the design variable to carry on the air blower first, two level of impeller putation. (2) With Equal circulation method carries on aerodynamic design.(3) Calculates slip ring and the the fan diffuser size parameter(4) air blower noise control.
Key words counter-rotating axial fan hub ratio impeller
