Marine explosion-proof axial fan

ApplicationThe explosion-proof symbol of explosion-proof fans is EdiiBT4They 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 ConditionsFor places where there are explosive gas mixtures of gradeii B and group T4.Ambient temperatures:-25～+50Relative humidity of the air:≤95%Cyclical vacillation:22.5°～45° (Vacillation cycle 5～10S)Sustained horizontal tilting:15°Sustained vertical tilting:10°Vibration:existentShock:existentStructural TypesCBZ type Explosion-proof,safe and reliable in operationWell anticorrosiveStrongly capable of resisting vacillationvibration and shockingType ExplanationThe 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,etcREMARKS 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=0.7～0.8Introduction company Qingdao Yongjian Marine Machinery Manufacture Co., Ltd.
