1、SDS隧道射流风机一、特性及应用   SDS遂道射流风机采用先进技术工艺所研制开发的新产品，其外壳由美国进口专用机床旋压翻边成形，叶轮段内壁经金加工，既保证机壳的同轴度和强度，又保证叶片径向间隙，表面涂装处理，外形美观及防腐性能优良。内置鼠笼全封闭式射流通风机配套电机，并设法兰安装盘，电机绝缘等级为H级，防腐等级为IP55。其风量大小可以通过改变叶片数和叶片角度来满足要求。对于噪声要求高场合，可增加消声器来减少其噪声。   遂道式通风机分单向射流风机SDS和双向射流风机SDS(R)二种通风形式，SDS(R)型遂道射流风机有电子式和机械式二种切换方式，可在30秒钟内正反转切换到风机额定转

2、速。   该风机各项性能指标及耐腐蚀、可靠性、经济性等技术、质量要求和经济指标完全能适应水利大坝工程、公路、铁路、地铁等隧道的实际使用。说明：单向式风机型号为SDS，可逆式风机型号为SDS(R)例1：SDS-6.3-2P-4-4°表示直径为630mm的射流风机，转速2900rpm，4叶片，安装角4°。例2：SDS(R)-6.3-2P-4-4°表示直径为630mm的可逆式射流风机，转速2900rpm，4叶片，安装角4°。三、性能参数SDS性能参数风机型号风量(m3/s)出口风速(m/s)电机不带消声器带消声器机座号功率(kW)风机功率(kW)推力(N)声压dB(A)重量(kg)1D2D推
