《GB/T 13933-2008小型贯流式通风机》由TC238(全国冷冻空调设备标准化技术委员会)归口,主管部门为中国机械工业联合会。
本标准自实施之日起代替GB/T 13933-1992。
本标准规定了小型贯流式通风机的术语和定义、型式与基本参数、要求、试验方法、检验规则、标志、包装和贮存。
本标准适用于叶轮外径不大于300mm的小型贯流式通风机。
本标准修订GB/T 13933-1992《小型贯流式通风机》,与GB/T 13933-1992相比主要变化如下:
――调整了适用范围;
――增加了小型贯流式通风机的定义;
――调整了风机的基本参数;
――将产品型号编制方法作为资料性附录;
――删除对风机用电源类别及额定电压的要求;
――增加了风机制造的有关要求;
――增加了对风机轴承部位振动速度的要求;
――调整了风机工作环境条件的要求;
――调整了技术要求中对风量、风压的要求;
――将风机噪声的考核标准由A声级改为比A声级;
――精简了风机用小功率电动机考核的内容;
――增加了风机叶轮进行超速试验的要求;
――调整了检验规则的部分内容。
