Marine Explosion-Proof Centrifugal Fans

CBGD Series Marine Or Navy Explosion-Proof Centrifugal Fans

1. General
CBGD Series marine or navy explosion-proof centrifugal fans are designed and manufactured according to GB11799-2008 (Marine explosion-proof centrifugal fan), GB3836.1-2000 (Explosive atmospheres for electrical equipment – General requirements), GB3836.2-2000 (Explosive atmospheres for electrical equipment – Flameproof enclosure “d”), and the relevant regulations of the China Ship Inspection Bureau (Rules for Steel Hull Entry and Exit).

This series of explosion-proof fans has 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:
Explosion-proof, safe and reliable in operation, small size, light weight, low noise, strong anti-corrosive ability, strong vibration resistance, and strong impact resistance.

2. Structure
There are two structural types: type I (direct-coupling type) and type II (belt-coupling type). The construction is non-sparking.

The structure of type I is a motor direct coupling one, the impeller is mounted directly on the motor shaft, and the casing is fixed on the flange of the explosion-proof motor.

The structure of type II is a separate structure, the fan and the motor are put in different cabins, with a driving device, flexible couplings, and the driving device consists of bearings, bearing-box, shaft, brass rings, stuffing box, etc. It can be oiled and measured the temperature. One side be 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 single-suction structure according to the customer’s requirements.
