　　普惠风机的噪声控制方案

　　标准普惠风机噪声通常为75-95dB(A)。阻抗复合消声器可降低进出风口噪声15-20dB，弹性减振器减少结构传声12dB以上。某医院项目采用普惠风机配合消声房，使噪声从92dB(A)降至63dB(A)。最新研发的锯齿状叶片边缘设计，通过破坏涡流降低宽频噪声3-5dB。值得注意的是，管道振动会产生二次噪声，每10米应设置橡胶软连接。变频调速在降速20%时，噪声可降低约8dB。

　　Jiuzhou Pratt & Whitney fan Co., Ltd. was founded in 1996, with its headquarter in Nanhai District, Foshan City. It is an enterprise focusing on environmental protection ventilation equipment and integrating R & D, production, sales and service. Now it has become a domestic fan product manufacturer. The factory covers an area of 115000 square meters, and the standard workshop area is 100000 square meters. It has laser, plasma, machining center, die casting, dynamic balance and other general and CNC equipment as well as precise measuring tools and testing instruments. It has built multiple production lines, used the auxiliary design system, applied the MGS, cat automatic testing system, and built the fan pneumatic performance testing center and motor performance testing center 。 The company cooperates with a number of colleges and universities in technology research and development and talent cultivation projects, which has brought up a number of professional and technical talents.

　　22、偏航速率。可以设计偏航阻尼限制偏航速率。 上风向风机一般采用主动偏航方式，驱动系统上风向风机一般采用主动偏航方式，驱动系统包括偏航电机、减速机、偏航刹车机构等，这种驱包括偏航电机、减速机、偏航刹车机构等，这种驱动方式塔架需要承受偏航扭矩。动方式塔架需要承受偏航扭矩。偏航控制偏航控制大多数水平轴风机采用偏航机构旋转风轮顺风，限大多数水平轴风机采用偏航机构旋转风轮顺风，限制功率输出。但这种方法响应速度很慢，原因有:制功率输出。但这种方法响应速度很慢，原因有:（1）机舱和风轮有很大的惯性力矩；）机舱和风轮有很大的惯性力矩；（2）垂直于风轮的风速与偏航角度的变化呈正弦）垂直于风轮的
