为了满足纺纱厂对空气温度和相对湿度的不同要求、每个车间都装有空调送风系统.由于风量需求大,所以广泛采用轴流风机为送风设备.这种风机运行时,虽然动力消耗小、但风机本身产生的噪声较高、一般在100dB以上.该噪声从设在车间内的回风窗向车间内辐射,危害操作工人健康,并从设在车间外的进风口向室外辐射、污染了环境,危害了临近的办公室和居民区.
In order to meet the spinning mill on the air temperature and relative humidity of different requirements, each workshop is equipped with air-conditioning air supply system.Because of the large wind demand, it is widely used axial fan for the air supply equipment.This fan is running, although the power Consumes less, but the fan itself produces a higher noise, usually above 100dB.The noise from the return air window located in the workshop to the workshop radiation, endangering the health of workers, and from the vent located outside the workshop to the outdoor radiation , Pollute the environment and endanger the nearby offices and residential areas.
