| 摘 要： | 通常,离心风机的干涉噪声声是主要的噪声源,也是研究的主要对象.本文建立了离心风机的干涉噪声强度与机器几何参数和气动参数的关系,从而可以预测离心风机的干涉噪声并近似估计其总的噪声级.这对离心风机的设计有一定指导意义.

| Abstract: | Usually interaction noise is the main noise source of a centrifugal blower, therefore the main subject of research. This paper develops the relationships between the interaction noise and the geometry of impeller and volute, operating conditions, so that it is possible to predict the sound pressure level of the interaction noise produced by a centrifugal blower and evaluate the total sound pressure level approximately. There is some guiding meaning for designing centrifugal blowers. |
