1. 概述
CGDL系列舰船用率低噪声离心通风机(以下简称通风机)是一种新型节能、低噪声舰船用产品。通风机通过专门设计和加工,具有效率高(>80%)、噪声低、不会超载、运转平稳和满足舰船条件要求等特点,它适用于各种舰船的通风换气,也适用于其它相适应的场合。
2. 特点
通风机采用了特殊设计的机翼型叶片和进风口。机壳的尺寸和型线也按特征速度进行专门设计。叶轮进行专门加工,从而使气流流动更良好,使通风机具有效率高、噪声低等优点,由于功率特征至大流量区后反而下降,故电动机不会因超载而损坏。
通风机在设计和制造中充分考虑到舰船用的特殊条件要求,叶轮用铝制造并经严格动平衡校正,超速试验。故通风机还具有耐腐蚀性好、抗摇摆、抗冲击、振动、运转平稳和安全可靠等特点。
3. 结构型式
通风机为卧式,电动机直联结构,需要时也可制成立式结构。
通风机叶轮由铝合金制成,叶片为机翼型,并经过严格动平衡校正,具有优良的空气动力性能。机壳、进风口等由普通钢板制成,采用镀锌等防腐措施,机号≥40时,通风机加有机架(40以下无机架)。

1. General
CGDL Series marine or navy high-efficiency.Low-noise centrifugal fans (thereafter called the fan) are new-type&energy-save.Low-noise marine products.By the special design and process.The fans are characterized with high-efficiency (>80%), low-noise, no overload, stable running and meeting the marine conditions etc.They are suit-stable running and meeting the marine conditions etc.They are suitable for every cabin air ventilating and exchanging on ships.They are also applicable in other places that suit.
2. Features
The fans are adopted with designed specially aerofoil blade and inlet.The dimension and line of casing are designed specially according to characteristic speeds.The impellers are processed specially so that air flows perfectly and the fans have the advantages of high-efficiency and low-noise.When power get to large flow, it gets down opitely.Therefore, the motor can not be damaged because of overload.
In the course of designing&manufacturing, we had thought fully of the marine special conditions, the impellers are strictly made by dynamicbalance adjustment& over speed test.Therefore, the fans also have the features of good-corrosive resistance.Resistance to swing, resistance to shock and vibration, stable turning, safety& reliability, etc.
3. Structure
The fans are in horizontal pattern with direct coupling for the motor.However it can also be constructed into a vertical pattern.
The fans impellers are made by aluminum alloy and blades are like aerofoil.They are adjusted strictly by dynamic balance.So that,they have good airdynamic performance.The casing and inlet are made by common
steel and adopted with corrosion pvention of galvanization.When the machine number is equal to or more than 40, the fans add to frame.
Theoutlet directions of No. 40~80 of the fans which exist between0°and 225°, change in 22.5°

本公司主要产品有:轴流风机 JCZ (CZ)、CLZ、 CDZ、CDJZ、CZF、JZL、CWZ (CXA)、CZT、FA、T30、 T35; 离心风机JCL (CLQ)、CWL (CXL)、 CQ、CGDL、9-19、9-26、4-72、AZY;防爆风机CBL、CBGD、 CBZ、CBZT、FAX、BT35; 水力驱动驱气风机CSZ、CSL 系列等船用、陆用风机产品及菌形通风筒、鹅颈通风筒、磁力启动器、防火风闸、暖风机、钢质蒸汽散热器、消音器等30余个系列产品,从不同角度、特型满足各类用户的不同需求。
在带电病件及壳体之间或带电部件之间需要用绝缘材料加以隔离,而绝缘料的使用寿命与其材料本身的绝缘等级及使用温度有很大的关系。风机电机作为一个能量转换或信号转换元件。通风机电机为了可靠运行在运转过程中本身存在着能量损耗。船用风机其中:轴的材质为45#钢。角框的角铁或镀锌板制作; .
故通风机具有耐蚀性好,抗摇摆,抗冲击,振动,运转平稳和安全可靠等特点。船用低噪声轴流通风机叶轮由铝板模压成的叶片与钢制镀锌的铆接而成,机壳与支架等由普通钢板制成,并经防腐处理。超速实验通风机制成从电动机端正视,叶轮按逆顺时针方向旋转。由于通风机叶片由铝板制成。

可制成III型结构,即风机和电机分隔舱型式,中间加传动装置,密封填料函和挠性联轴器的结构,主要用于排除危险舱室的气体。防爆通风机制成从防爆电机端正视,叶轮按顺时针方向旋转的结构。船用防爆轴流通风机结构形式: 根据用户特殊需要。船用离心风机跟轴流风机对比,所选用的新风机应考虑充分利用原有设备、适合现场制作安装及安全运行等问题船用防爆离心风机改变了风管内介质的流向,而轴流风机不改变风管内介质的流向;前者安装较复杂前者电机与风机一般是通过轴连接的,后者电机一般在风机内;前者常安装在空调机组进、出口处,锅炉鼓、引风机,等等。后者常安装在风管当中、或风管出口前端。此外还有斜流(混流)风机,风压系数比轴流风机高,流量系数比离心风机大。添补了轴流风机和离心风机之间的空白。同时具备装简单方便的特点。
