JCZ-140B Marine Axial Flow Fan

JCZ-140B marine axial flow fan 

1. FOREWORD
JCZ-140B marine axial flow fan is capable of blowing air, ocean air containing salt vapour, and corrosive air containing a small quantity of oil vapour. They are suitable for cabin air ventilation and exchange on oceangoing vessels. They are also applicable in other places that suit.
The fan is designed and manufactured according to GB11864 《Marine axial flow fans》 and《The Rules and classification of Sea-going Steel ships》 approved by the Register of the People’s Republic of China.
2. WORKING CONDITIONS
Medium temperature: -25℃ ~ +50℃
Max relative humidity: 95%
Periodical swing:±22.5°
Continued transversal incline:±15°
Continued longitudinal incline:±10°
Vibration: existent
Impact: existent
3. CHARACTERISTICS
The Machine Casing can be opened..
Reverse rotation possible.
Good anti-corrosiveness.
Strong resistance against swing, vibration-proof and impact resistant.
4. STRUCTURE TYPE
The fan is manufactured with a built-in casing motor structure. The vane wheel is directly mounted on the motor shaft.
The vane wheel is made of anti-corrosive case aluminum alloy while the casing is made of welded common steel.
As desired, the casing can either be made into an integral one or an open type along the axial direction. In the later case, the vane wheel and the casing so as to bring convenience for on-the-spot repair and the replacement of its spare parts.
Viewed from the motor side, the vane wheel rotates clockwise while in service the ventilator is allowed to rotate reversely.
The fan can be matched with marine AC motor of 380V, 50HZ or 440V,60HZ,or other customised voltage and frequency.

5.MODELS

　The models of fans are expressed by the first letter of the Chinese phonetic name, the outer diameter of the vane wheel, the power and the rotational speed of the motor ,etc.

For example:

JCZ-140B/22----970

Where：

J-for naval ship use

C-for merchant ship use

Z-axial flow ventilator

B-impleller code

140-the outer diameter of the vane wheel 140cm

22-the power of motor 22kw

970-the standard rotational speed 970r/min(50Hz)
