泵,作为一种机械动力设备,不可避免地辐射着噪声。在某些泵房内,泵的噪声是主要环境污染源。 噪声对人体健康有着潜在的危害,因此对泵的噪声有许多国家已作为一项技术指标列入泵产品性能中。 在我国,于1984年10月,机械工业部颁布了石化通用机械工业局企业标准《泵的噪声测量与评价方法》(JB/TQ 391-84)。 为了使从事泵的技术工作人员对该标准加深正确理解,推动标准的贯彻执行,本文就标准中涉及到的一些声学名词术语等有关内容,谈些解释性的看法,同时对标准中失误之处,作了必要的更正。
Pump, as a mechanical power equipment, inevitably radiates noise. In some pumping stations, pump noise is a major source of environmental pollution. Noise is potentially harmful to human health and therefore many countries have included pump noise as a technical indicator of pump performance. In China, in October 1984, the Ministry of Machinery Industry promulgated the enterprise standard “Measurement and Evaluation of Pump Noise” (JB / TQ 391-84) of General Machinery Industry Bureau of Petrochemical Industry. In order to make the technical staff engaged in pumps to deepen the understanding of the standard correctly and to promote the implementation of the standard, this article discusses some of the terms related to the acoustic terms, explain some of the views, at the same time, the error of the standard , Made the necessary corrections.
