CGDL series marine or navy high efficiency low noise centrifugal fan
1. General
CGDL series marine or navy high efficiency low noise centrifugal fan (hereafter called fan) is a kind of new type, low-noise ship fan developed and designed by our company. The fan is processed and processed by special process, with high efficiency (>80%), low noise, low vibration, stable operation and meets the requirements of marine products. It is suitable for various ships’ ventilation, and it is also suitable for general occasions.
2. Features
The fan adopts special designed aerofoil blades and air inlet. The size of blade and hub are designed and processed by special process, so that the air flow is smooth, the fan has high efficiency, low noise and other advantages. Due to the special structure, the fan has the advantages of high efficiency and low noise. The fan is designed and manufactured in full accordance with the special requirements of ships, and the impeller is strictly balanced by dynamic and static balance. After testing, the fan also has the characteristics of corrosion resistance, vibration resistance, impact resistance, overload, stable operation and safe and reliable.
3. Structure
The fan is of inlet type. The motor is directly connected, and it can also be made into belt drive structure. The fan impeller is made of aluminum alloy, the blade is aluminum alloy, and it is strictly balanced by dynamic and static balance, with high efficiency, good aerodynamic performance. The inlet is made of cast aluminum alloy, and the outer frame is made of cold-rolled steel plate (No.≥40, the fan can also be made of 420 stainless steel). The air direction of the fan is 0°-225°, and the change is 22.5°.
