CBZ series marine explosion-proof axial fans (the explosion-proof fan) are designed and manufactured according to GB11800-89 Marine Explosion-Proof Axial Fans, GB3836.1-2000《Electrical Apparatus For Explosive Atmosphere》, GB3836.2-2000《Electrical Apparatus For Explosive Atmospheres, and Explosion-Proof Electrical Equipment "d"》, 《Steel Sea Ship in Class and Building Rules》
This series fans have been examined and proved up to standard by the Quality Supervision Center of Explosion- Proof Electric Apparatus of the PRC and have got the certificate of inspection. They have also been examined by the Register of Shipping of PRC and have got the certificate.
Theses explosion- proof fans are best suited to pumping out gas mixtures or vapor 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 land's.
Explosion-proof, safe and reliable operation, anticorrosive, swing resistance and shock resistance.
There are three structural types: Type I (deck type), Type II (tube type) and Type III (separate cabins type). The construction is non- sparking.
Type I explosion-proof fan has an explosion-proof motor installed on the top of the frame and surrounded with 2 mesh/inch stainless steel screen. The fan is vertically fixed on the deck. It can be for air supply or air exhaust.
Type II explosion-proof fan has no hood and motor is built-in type, which is fixed on the housing by support vertically or horizontally, and can also be installed and flexible coupling. It is for gas exhaust of dangerous compartment.
According to the customer 's special requirement, the fan can be made into Type III structure, the fan and the motor are separated. It consists of a driving device, glands and flexible coupling. It is for gas exhaust of dangerous compartment. Taking a front view from the motor, impeller rotates clockwise.
