电动机在石油化工厂中广泛应用,是主要的噪声源之一。通常电机噪声的治理方法是安装隔声罩和消声器,但采用这些措施费用高,而且需要解决电机温升和维修不方便等问题。如果有性能良好的低噪声电机可供选用,不但能达到噪声控制的要求,避免出现上述附带问题,还可节省大量本刊转载这篇文章,目的就在于使广大设计人员了解当前我国低噪声电机的性能、研制情况和发展前景。
Electric motors are widely used in petrochemical plants and are one of the major sources of noise. Usually the motor noise management method is to install noise enclosures and mufflers, but the use of these measures costly, and the need to address the motor temperature rise and inconvenient maintenance and other issues. If there is a good performance low-noise motor available for selection, not only to achieve the noise control requirements, to avoid the incidental problems, but also save a lot of Articles reproduced this article, the purpose is to enable the majority of designers to understand the current low-noise motor Performance, development situation and development prospects.
