alt="离心风机" src="/UploadFiles/2022-12/2/2022121310512442896.jpg" style="border-width: 0px; border-style: solid;" /></p> <p style="margin: 5px 0px 10px; line-height: 2em; text-indent: 2em;"> <span style="font-family: 微软雅黑, "Microsoft YaHei"; font-size: 16px;">提高离心风机效率的方法有:</span></p> <p style="margin: 5px 0px 10px; line-height: 2em; text-indent: 2em;"> <span style="font-family: 微软雅黑, "Microsoft YaHei"; font-size: 16px;">1、风机模型:设备的模型良好优化是上升设备效率的重要原因之一。叶轮轮盖、叶片的型线对它的效率很重要,合理的叶型会影响到设备效率。通过对叶片进出口角度的调整,轮盖型线的优化,进风口流道的优化等上升风机效率ã€?/span></p> <p style="margin: 5px 0px 10px; line-height: 2em; text-indent: 2em;"> <span style="font-family: 微软雅黑, "Microsoft YaHei"; font-size: 16px;">2、性能参数匹配度:离心风机是在系统中工作,风量和风压与系统不匹配的情况下,会造成风机的运行效率不高。可以采用良好的CFD模拟技术,选择运行效率点与系统性能越匹配的设备,使它的运行区域与管网系统匹配,使改造后的设备运行效率越高ã€?/span></p> <p style="margin: 5px 0px 10px; line-height: 2em; text-indent: 2em;"> <span style="font-family: 微软雅黑, "Microsoft YaHei"; font-size: 16px;">3、管网优化:如果配置的管网不合适,设备在运行中会因为阻力的增大降低运行的效率,致使能耗增加。管网设计要合理,避免扰流的产生。为减少气流在设备进出管路中产生扰流,出入口管道尽量设计合理,减少弯头,变径设计合理,从而上升它的运行效率ã€?/span></p> <p style="margin: 5px 0px 10px; line-height: 2em; text-indent: 2em;"> <span style="font-family: 微软雅黑, "Microsoft YaHei"; font-size: 16px;">4、调节方式:离心风机运行中,系统的实际阻力与理论阻力难免有所偏差,因此需要调节它的工作点以适用系统实际的阻力需要。它的调节方式一般有入口挡板调节及变速调节,入口挡板调节造成的阻力损失较大,容易导致设备效率不高。通过变频电机或永磁电机调整转速,可以调节风量,越加适应管网系统,达到降低设备能耗的效果ã€?/span></p> <p style="margin: 5px 0px
