SDS隧道射流风机(SDS tunnel jet fan)
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。
Characteristics and Application
The new product SDS tunnel jet fan using advanced technology developed, its shell is imported from the United States special machine spinning flanging, the impeller inner wall is processed, not only ensure the alignment and strength of the casing, and ensure the radial clearance of the blades, surface coating processing, beautiful appearance and excellent anticorrosive performance. Built in squirrel cage, totally enclosed jet ventilation fan, equipped with flange mounting plate, the motor insulation grade is H, and the corrosion protection grade is IP55. The volume of air can be satisfied by changing the number of blades and the angle of the blade. For high noise requirements, the muffler can be increased to reduce its noise.
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速。
Tunnel type fan unidirectional jet fan SDS and bidirectional jet fan SDS (R) two types of ventilation, SDS (R) type tunnel jet fan with mechanical and electronic two switching methods can be positive in 30 seconds to switch to the fan rated speed
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°。
The performance indexes of the fan, as well as its corrosion resistance, reliability and economy, quality requirements and economic indexes, can be fully adapted to the actual use of water conservancy dam projects, tunnels, railways and subways.
Description: the one-way fan type is SDS, and the reversible fan type is SDS (R)
For example 1:SDS-6.3-2P-4-4 degrees, the diameter of 630mm jet fan, speed 2900rpm, 4 blades, installation angle of 4 degrees.
Example 2:SDS (R) -6.3-2P-4-4 degrees, means a reversible jet fan with a diameter of 630mm, with a speed of 2900rpm, 4 blades, and an installation angle of 4 degrees.
