地铁风机设备在招标中对关键技术部件的要求

Requirements for Key Technical Parts of Metro Fan in Tendering

为了确保地铁风机设备的招标质量及招标工作的顺利开展,根据不同地铁线路风机设备招标的实际经验和教训,结合对目前国内几个地铁风机供货商的实地考察和技术交流情况,从风机用户需求书的编制过程出发,提出在编制风机设备用户需求书时针对叶轮、电机、制动方式、振动监测、能效等级、主要接口等几个关键控制项所应注意的事项,以期对类似工程有所借鉴。

In order to ensure the smooth tendering and the quality of metro fan equipment,according to the practical experiences and lessons in metro fan equipment tendering in some metro lines,also combined with the on-the-spotinvestigation of several fan suppliers in China and technical exchanges,the compilation of user＇s requirement book for metro fan is stressed,in which matters need special notice,such as the impeller,electric engine,breaking mode,vibration detection,energy efficiency grade and main interfaces arc mainly discussed.
