CL, CBL-58 marine explosion-proof centrifugal fan

There are two types of explosion-proof ventilation fans, namely Type I (direct connection)

And Type II (compartmentalized). The overall structure is spark free.

Type I (direct connection) explosion-proof ventilation fan is made with an explosion-proof motor direct drive structure. The impeller is directly mounted on the motor shaft, and the casing is fixed on the explosion-proof motor flange.

Type II (compartment type) is an explosion-proof ventilation fan and motor compartment structure. Composed of a fan, transmission system, elastic coupling, electric motor, etc. The transmission group consists of bearing body, bearing, shaft, copper ring, sealing packing, etc., and can measure temperature and add oil. One end is directly connected to the explosion-proof ventilation fan, and the other end is directly connected to the bulkhead.

Explosion proof ventilation fans are horizontal, single-stage, single suction, and airtight structures, and can also be made into vertical structures.

Explosion proof ventilation fans can be made to rotate clockwise (right turn) or counterclockwise (left turn):

Reverse (left turn) - Looking from the explosion-proof motor end, the impeller rotates counterclockwise, indicated by "L".

Turn clockwise (right turn) - from the explosion-proof motor end, the impeller rotates clockwise, indicated by "R".

The outlet position of explosion-proof ventilation fan is made into the following basic types according to the direction of impeller rotation (see Figure 1). As needed,

The CBL series marine explosion-proof centrifugal fans (hereinafter referred to as "explosion-proof fans") are designed and manufactured in accordance with the general requirements of GB11799-89 "Marine Explosion proof Centrifugal Fans", GB3836-83 "Explosion proof Electrical Equipment for Explosive Environments", as well as the relevant provisions of "d" for explosion-proof electrical equipment and the current "Code for Classification and Construction of Steel Ships".

The position of the air outlet allows for other types that vary by 30 ° or 22.5 °.

It can transport mixed gases or vapors containing flammable and explosive substances, air, marine air containing salt spray, and corrosive air containing oil mist.

Explosion proof ventilation fans are suitable for extracting flammable and explosive mixed gases or vapors from places such as oil tanks, cargo holds, pump rooms, battery rooms, ammunition rooms, aircraft hangars, paint rooms, etc. on ships. They are also suitable for ventilation and air exchange in other compartments of ships or corresponding places in various departments on land.

Explosion proof ventilation fans can be equipped with 50HZ, 380V or 60HZ, 440V, YB-H series explosion-proof marine three-phase asynchronous motors or Y-H series marine three-phase asynchronous motors.
