CBL Marine explosion-proof blower
CBL series explosionproof centrifugal fans for marine use are designed and manufactured according to GB11799-89《Marine explosionproof 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》.
This series fans have been examined and proved up to standard by 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 China and have got the certificate.
The explosion-proof symbol of explosion-proof fans is EdⅡBT4 They can be delivered for gas mixtures or vapour containing combustibles and explosives, for ordinary air, for sea air containing salty fog ,for air containing oil fog and other corrupt air supply or extradition.
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 land's.
AC 50Hz,380V or 60Hz,440V type YB-H(explosion-insular) for marine use may be mounted on these fans.
3. Operation Conditions
For places where there are explosive gas mixtures of grade Ⅱ B and group T4.
Relative humidity of the air:≤95%
Cyclical vacillation:22.5°～45° (Vacillation cycle ５～１０Ｓ)
Sustained horizontal tilting:１５°
Sustained vertical tilting：１０°
Vibration :existent Shock :existent
4. Structural Types
There are two structural types :type Ⅰ (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 type Ⅱ 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.
The fan may be made into a horizontal or vertical, single stage , single-drawing and airtight structure by the customer's requesting.
The fan can be made into a counter-clockwise rotating type or a clockwise one.
The counter-clockwise rotating type(Left turning type)-Taking a front view from the motor side, you will see the vane wheel turns counter clockwise. We use“L” to indicate it, and by the same way, the clock wise rotating type can be indicated as “R”.
The outlet position of the fan ,according to the rotating direction of the vane wheel, is made into the following main types. by your requesting ,the outlet position is allowed to use other types ,the nagle of which 30° or 22.5°.
Explosion-proof ,safe and reliable in operation
Small in size ,light in weight, and low in noise
Strongly capable of resisting vacillation, vibration and shocking
