目前在我们的生产生活及科研中,离心机械应用已是相当普遍。本文主要介绍离心现象、离心机械的工作原理、常用的离心机械,并就企事业及居民家庭常用到离心风机的噪声来源及降噪方式上作了重点阐述。因为减噪是社会发展需求,近年来,国家颁布了新的强制性标准,对居民生活环境和工业企业的噪声的排放做了严格的规定,而工业生产中广泛使用的离心风机是噪声污染的一个重要来源,通过降低噪声满足国家规范,保护人类健康。
At present in our production and living and scientific research, centrifugal machine applications have become quite common. This paper introduces the centrifugal phenomenon, the working principle of centrifugal machines, centrifugal machines commonly used, and on the noise sources and noise reduction methods commonly used by enterprises and households to centrifugal fans made elaborate. Because noise reduction is a social development requirement, in recent years, the state has promulgated new mandatory standards that strictly regulate the emission of noise in residential living environment and industrial enterprises. However, the centrifugal fans widely used in industrial production are noise-polluted An important source of protection of human health by reducing noise to meet national norms.
