立式水电机组的低噪声设计及声功率测定

Design of Low Noise Level and Determination of Sound Power for Vertical Hydroelectric Generating Set

在立式水电机组噪声分析的基础上，提出并实施了低噪声设计方案；针对立式水电机组的特点，按国家标准测定了其声功率级。

Based on the noise analysis of the vertical hydro-electric generating set,the set' s design plan of low noise level has been put forth,implemented and proved sucessful by determination of set's sound power level according to GB 10069 2-88 Key wrods vertical hydroelectric generating set;noise analysis;design of low noise level;sound power level
