        摘要:防爆电气设备主要指在危险场所,易燃易爆场所所使用的电气设备。那么防爆电气设备安装规范是什么?防爆电气设备安装标准有哪些?

下面一起来了解一下防爆电气设备安装。

  防爆高压旋涡风机工作原理 

  由于叶轮叶片中间的空气受到了离心力的作用,向叶轮的边缘运动,叶轮旋转所产生的循环气流,在那里空气进入泵体环行空腔,重新从叶片的起点以同样的方式再进行循环。 

  它采用隔爆外壳把可能产生火花、电弧和危险温度的电气部分与周围的爆炸性气体混合物隔开。但是,这种外壳并非是密封的,周围的爆炸性气体混合物可以通过外壳的各部分接合面间隙进入电机内部。当与外壳内的火花、电弧、危险高温等引燃源接触时就可能发生爆炸,这时风机的隔爆外壳不仅不会损坏或变形,而且爆炸火焰或炽热气体通过接合面间隙传出时,也不能引燃周围的爆炸性气体混合物。

  防爆高压旋涡风机配置 

  1、机壳材质:采用高强度压铸铝,压铸铝与奔驰汽车轮毅相同铝材,相对于普通铝合金来说,压铸铝更坚固,相对于铁壳风机,更有轻量化的作用。 

  2、电机性能:采用电机,电机是一款宽频,宽压电机,列入单相110V、230V;工业三相220V、380V、415V、660V等,电机频率可45-75HZ调频,IP55防护等级 F级绝缘等级,其优势是国内电机达不到的工艺,深受国内外客户青睐。 

  3、风机油封:采用耐高温材料采用氟橡胶可承受-25℃至300℃。相对于一般油封工作时其唇缘的温度高于工作介质温度20~50℃,性能更稳定,免维护,寿命更久。 

  4、风机轴承:核心部件采用优质品牌轴承,轴承zui高可承受350摄氏度,4000转每分钟的转速。对于普通性能轴承,性能稳定,低噪音,免维护,寿命更久,可保证风机运行更久。
