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°
风机概况:
船用通风设备云南省怒江州福贡可方便地开启轴流通风机的维护: 1、 风机只有在完全正常情况下方可运转; 如果风机在维修后开动时,则注意风机各部位是否正常。定期风机内部积灰、污垢等杂质,随时检查皮带松紧度,防止皮带紧度,防止皮带打滑。


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。
风机与地面或风机与墙壁用垫垫平,不允许用螺栓强行拧紧,以防机架机壳变形,影响风机性能或造成机壳与叶轮间隙变更而刮碰。船用通风机安装:安装完毕后,详细清点工具。船用通风机安装:安装时管道与风机仔细观察风机与管道内有无遗留的工具,螺栓,手套,棉线,电线头等不应有的杂物。定期检修分为运转状态下的运转检修和停机时的停机检,需进行一年一度的定期检修。
轴流通风机的主要故障: 轴承温度过高。轴承箱振动剧烈,轴承损坏或轴弯曲,润滑脂质量不良或含杂质等。

故便于现场检修和更换零部件。船用轴流通风机通风机制成从电动机端正视,叶轮按顺时针方向旋转。在使用中,允许通风机逆向旋转。通风机可配用380V/415V,50Hz或440V。船用轴流通风机机壳可根据需要制成整体式或沿轴向开启式。开启式机壳是将叶轮和电动机装在可开启的半机壳上60Hz船用交流电动机。船用防爆轴流风机中,其风叶是甩风还是崴风,主要是看风机使用的是哪种形式的叶轮,如果是前向叶轮,那么风叶是崴风,如果是后向和机翼型,则风叶是甩风,或者叫切风。所以说,船用防爆轴流风机风叶甩风或崴风,主要是与叶轮形式有关。
