一、概述 目前国内外用于仪器或设备上的轴流风机,大多数为开放式。如果风机电机在野外、露天暴露下工作,当受到雨、雪、露的侵袭以及潮气的长期腐蚀后,绝缘性能下降甚至破坏,线扎短路,电机烧毁,风机不能正常工作。DF—21上的风机要求在野外暴露下工作,在雨、雪、露、潮、高低温、风砂、灰尘等恶劣环境下能正常停转。100FzYx—SA防水风机,经一
I. Overview At home and abroad for the instruments or equipment on the axial fan, most of the open. If the fan motor is exposed in the open air and exposed to the sun, the insulation performance will deteriorate or even be damaged when it is exposed to rain, snow, dew and long-term corrosion of moisture.
