众所周知,设备振动和噪声对操作人员起着有害的作用,而离心通风机空气动力学的高频噪声对工厂附近居民带来不良的影响;振动和噪声超过一定范围,设备或部件磨损和损坏得更快,最终可能造成事故。随着振动频率增加,有害作用也随之增大。频率25～90赫的振动,尤其有害;垂直方向的振动,对人的作用最为不利。因此,在设计新机器和改造现有设备时,应采取措施,最大限度地降低工艺设备的振动和噪声。下面列举的苏联有关资料,
It is well-known that equipment vibration and noise are detrimental to the operator and that the aerodynamic high-frequency noise of the centrifugal fan has an adverse effect on the residents in the vicinity of the plant; vibration and noise exceed a certain range and equipment or components are worn and damaged Faster and eventually could cause an accident. As the vibration frequency increases, the harmful effects also increase. Frequency 25 ~ 90 Hz vibration, especially harmful; vertical vibration, the most adverse effect on people. Therefore, when designing new machines and retrofitting existing equipment, steps should be taken to minimize the vibration and noise of process equipment. The following list of Soviet-related information,
