Marine Explosion-proof Centrifugal Fan CBGD Series
General
CBGD series marine explosion-proof centrifugal fans (the explosion-proof fan) are explosion proof products which developed from CBGD series marine centrifugal fans. The series are designed and manufactured according to GB11709-2008 Marine Explosion-proof Centrifugal Fans, GB3836.1-2000 《Electrical Apparatus For Explosive Gas Atmospheres》, GB3836.2-2000 《Electrical Apparatus For Explosive Gas Atmospheres》, and ship regulations of 《Steel Sea Ship in Class and Building Rules 》. The fans are suitable for ventilation of chamber which contains combustible and explosive gas. They are also applicable for other suitable place.
This series fans have been examined and proved up to standard by the Explosion-Proof Inspection Authority 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.
Features
The series explosion-proof fans have high efficiency, low noise, no overload, well anticorrosive, strong swing, vibration resistance and shock resistance, stable running and safety, reliability etc.
Structure
There are two structural types: type I (direct-coupling type) and type II (separate cabins type). The construction is non-sparking.
Type I is a motor direct coupling one, on the motor shaft the impeller is mounted directly, and the casing is fixed on the flange of the explosion-proof motor. Type II is a separate structure, the fan and the motor are separated. It consists of fan, driving device, flexible couplings and motor. The driving device consists of body bearing, bearing, shaft, brass rings and glands. It can be oiled and measured the temperature. One side is fixed on the fan and the other side will be mounted on the bulkhead.
The fans can be made into a horizontal or vertical, single-stage, single-suction and straight structure, it also can be made into vertical type.
