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 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
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 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 than 40, 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°
