CGDL Marine Low-noise Centrifugal Fan
1、General
CGDL Series marine high-efficiency, low-noise centrifugal fan (simply the fans) is 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 ventilating and exchanging on ships. They are also applicable in other places that suit.
2、 Features
CGDL Series marine high-efficiency, low-noise centrifugal fan are adopted with designed specially aerofoil blade and inlet. The dimension and line of casing are designed specially according to characteristic speeds. The impeller is processed specially so that air flows perfectly and the fans have the advantages of high-efficiency and low-noise. When power gets to large flow, it gets down oppositely. 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 dynamic balance 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
CGDL Series marine high-efficiency, low-noise centrifugal fan are in horizontal pattern with direct coupling for the motor. However it can also be constructed into a vertical pattern.
CGDL Series marine high-efficiency, low-noise centrifugal fan impellers are made by aluminum alloy and blades are like aerofoil. They are adjusted strictly by dynamic balance, so that they have good air dynamic performance. The casing and inlet are made by common steel and adopted with corrosion prevention of galvanization. When the machine number is equal to or more than40, the fans add to frame.
The outlet directions of No.40~80 of the fans which exist between 0°and 225°, change in 22.5°.
