The series are designed and manufactured according to Marine Explosion-Proof Fans, Electrical Apparatus for Explosive Atmospheres and ship regulation of Chinese and international.
Non-sparking fans are suitable for ventilation of chamber which contains combustible and explosive gas. They are also applicable for other suitable places.
This series non-sparking 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.
2.Features
This series non-sparking fans have the feature of high explosion-proof grade, high efficiency, low noise, no overload, well anticorrosive, swing resistance, vibration resistance and shock resistance, stable running and safety, reliability etc.
3.Structure
There are two structural type:
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 separate structure, the fan and the motor are separated. It consists of fan driving device, flexible coupling 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 fan may be made into a horizontal, single-stage, single-suction and airtight structure, it also can be made into vertical type.
