上海地铁1号线11座地下车站的环境控制系统中共使用了从德国——丹麦透平联合公司引进的102台3种不同规格型号的轴流风机。本文就这3种风机随机抽样在德国Voith工厂测试中心的标准试验台上分别按德国工业标准VDI2044、VDI2081和DIN45635进行试验验收结果提出报告。全文对空气动力学标准试验台的组成、数据采集、风机性能计算、风机噪声值实测、环境本底噪声值测定、环境修正值与测定表面附加值的确定以及轴流风机A声功率级理论计算等方面作了较详尽的介绍。
The environmental control system of the 11 underground stations of Shanghai Metro Line 1 used a total of 102 three-dimensional axial fans introduced from the German-Danish Turbo United Company. In this paper, three kinds of fan random sampling in the German Voith factory test center standard test stand respectively according to the German industry standards VDI2044, VDI2081 and DIN45635 test acceptance results were reported. The full text of the aerodynamic standard test bench composition, data acquisition, fan performance calculation, fan noise measurement, environmental noise floor value determination, environmental correction and determination of surface added value and axial fan A sound power level theory calculation Etc. made a more detailed introduction.
