CBL Series Marine Explosion Proof Centrifugal Exhaust Fan
1. Preface
CBL series explosion-proof centrifugal exhaust fans for marine use are designed and manufactured according to GB11799-89《Marine explosionproof axial flow fans》,and general description and explosion-proof “d” of GB3836-2000《Electrical apparatus for explosive atmospheres》 and 《Rules and regulations for the construction and Classification of Seagoing Steel Ships》.
2.There are two structural types :
typeI(motor-direct-driving type) and type II (Separate cabins type).The construction is spark free.
The structure of type I is a motor-direct driving one, The vane wheel is mounted directly to the motor shaft .and the housing is fixed on the flange of the explosion-proof motor.
The typeII is a separate structure, i.e. the fan and the motor are put into different cabins ,with a driving device, a pairs of flexible coupling .and the driving device consists of bearings, bearing box ,shaft, brass rings, stuffing .it can be oiled and measured temperature .One side is fixed on the fan ,and the other side will be mounted on the bulkhead.
