CBZ series Marine explosion-proof axial fan

CBZ series Marine explosion-proof axial fan
Product Detailed
CBZ series Marine explosion-proof axial fan BV&CCS certificate Well anticorrosive Strongly capable of resisting vacillation

 

 Application

The explosion-proof symbol of explosion-proof fans is EdiiBT4 They can be delivered for gas mixtures or vapour containing combustibles and explosives,for ordinary air,for sea air containing salf fog,for air containing oil fog and other corrupt air supply or extracition.

These explosion-proof fan series are best suited to pumping out gas mixtures or vapour containing combustibles and explosives in oil cabins holds,pump-rooms,battery cabins,ammunition cabins,hangars,paint houses,etc.They can also be used for ventilation of other compartments of shipping and corresponding place of lands.

AC 50Hz,380V or 60Hz,440V type YB-H(explosioninsular) for marine use may be mounted on these fans.

Operation Conditions

For places where there are explosive gas mixtures of grade ii B and group T4.

Ambient temperatures:-25~+50

Relative humidity of the air:≤95%

Cyclical vacillation:22.5°~45° (Vacillation cycle 5~10S)

Sustained horizontal tilting:15°

Sustained vertical tilting:10°

Vibration:existent Shock:existent

Structural Types

 

 

CBZ type

Explosion-proof,safe and reliable in operation

Well anticorrosive

Strongly capable of resisting vacillation

vibration and shocking

Type Explanation

The type of explosion-proof fans are expressed by the first letter of the Chinese phonetic name,the outer diameter of the vane wheel,the standard speed,and the power of the explosion-proof motor,etc

 

 

 

REMARKS

The actual preformance parameters of type CBZ-i (deck type)will be deviated from those of type CBZ-ii,in which their impellers are designed and manufactured by the same way.as consequence of its special structure-larger size outlet,without down stream guide vane,change direction of air flow,resistance caused by wire mesh guard and the rest.After due consideration,the actual performance parameters of type CBZ-i subject to correction and the method of correction as follows.

correction coefficient of flow rate:fQ=0.8~0.9.

correction coefficient of pressure(total of static pressure):fP=0.7~0.8
