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°

首页_船用离心排风机_江苏省无锡北塘区50Hz或440VII型管道式两种结构:I型甲板式带有风帽,防爆电机装在机架上部,整机立式安装在甲板上。II型管道式不带风帽,可立式卧式安装,也可装在甲板上。防爆轴流通风机防爆轴流通风机可制成I型甲板式通风机的防护等级:外壳防护主要是防人体触电或接近壳内带电部分或转动部分,防固体异物进入和防止由于进水,油等而引起有害影响,符合GB4942及IEC34-5规定。


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。
只能选择安装较为简单的单向流和管道式新风。此外,新风系统安装需要与装修同步,如果房屋已经装修完毕还需要安装新风的话就只能安装分体式新风系统。船用风机的安装要点风机卧地式安装将减振器通过联接螺栓固定于风机机座,用中心高调整垫板调节各减振器水平高度,用固定螺栓将风机固于已焊接在基础上的联接钢板上,如风机由于抗震等原因无需减振器,则将风机机座上的螺孔与基础上的预埋螺栓直接联接即可。
将整个转动组吊入预定位置,安装地脚螺栓,地脚螺栓的弯曲度应≤L /100(L为地脚螺栓的长度),地脚螺栓底端不应接触孔底,孔壁。地脚螺栓应受力均匀,并螺栓外露2~3扣。管道风机安装时将集流器喇叭口插入叶轮内用铁丝固定后然后松开铁丝将集流器下部与机壳下半部用螺栓固定初步调整叶轮与喇叭口的间隙。

即I型(甲板式),Ⅱ型(管道式)和Ⅲ型(隔舱式)。整机结构,均为无火花型。 I型防爆电机装在机架上部,机架周围2目/英寸不锈钢网,整机立式安在甲板上,可用于抽风或送风。船用防爆轴流通风机结构形式: 防爆通风机有三种结构II型防爆通风机不带风帽,防蚀电动机为内装式,由静叶撑脚固定在机壳上,可立式或卧式安装,也可安装在甲板上,可用于抽风或送风。通风机安装前,应检查各部件是否损坏,配套部件是否齐全,检查叶轮旋向与机壳旋向标识牌是否一致。安装管道时,应使其与风机进风口自然对正吻接,不得强行连接。管道应有支撑,不允许将管道重量加在风机上。风机装接后,拨动叶轮检查是否与固定件有摩擦碰撞等现象。如有碰撞,摩擦,噪声过大或较大振动时,应检查后再重新启动。应防止撞击通风机,不准异物和液体等进入风机内。应及时叶轮叶片上的积灰,以免影响平衡增大噪声。
