Stainless Steel Fire Damper

Overview:

Marine fire damper suits for all kinds of vessels and offshore oil platform ventilation and ain conditioning system. When a fire breaks out in a cabin, the fire damper can be closed manually or automatically, preventing flame from spreading to other cabins through ventilating pipe. lt plays a role of isolating areas and ensuring the safety of vessels and platforms.

Marine fire damper can be divided into two types according to the functions: the damper for fireproofing and the damper for discharging smoke.
The damper for fireproofing is installed in the fire compartmentation place of the ventilation system and air conditioning system. lt is uauslly open for ventilating. When the fire occurs, it wil be closed automatically and prevent the fire from spreading when the tempreture in the ventilating pipe reaches to 70 degrees.
The damper for discharging smoke is mainly used in mechanical smoke extraction system and usually closed. When the fire occurs, it will discharge smoke automatically or manually by automatic fire alarm linkage signal. It will be closed automatically and play the role of isolating areas when the temperature in the ventilating pipe reaches to 280 degrees.
Our company has been one of the first domestic units to produce marine fire damper for over twenty years. Our company is also one of the standard drafting units of CB/T3557-1995 “marine fire damper”. Our engineering and technical staff spent more than two years developing the new type fire damper according to users’ feedback information and valuable experience.

Fault analysis and maintenance:

Fault phenomenon

Reason

Examine and repair

Fire damper closed

1. The air source is not supplied

2. The manual reversing valve is damaged

3. Cylinder damage

4. The solenoid valve coil is burnt out

1. Check the air supply pipeline

2. Replace the manual reversing valve

3. Repair or replace the cylinder

4. Replace the coil

The indicator light on the control box does not display

1. The connector is loose

2. Signal box switch circuit fault

3. The indicator light is damaged

1. Reconnect the line

2. Repair the switch circuit

3. Replace the indicator light

The power transmission of fire damper cannot be opened

1. The fuse is burnt out

2. The cylinder spring is damaged

3. The windshield blade is rusted and stuck

4. The relay is damaged

1. Replace the fuse with a new one

2. Replace the spring with a new one

3. Remove rust and polish movable wind vane

4. Replace the relay with a new one

The brake switch is not in place

Long term ventilation leads to dust accumulation at the brake disc, and the brake disc shaft is rusted and stuck

1. Do a good job of monthly inspection. If the switch is not in place, deal with it. Activate the air brake and refuel the rotating shaft

2. Remove the air brake in important areas for thorough cleaning

3. Longer term: the new platform is built, and the oil nozzle is added at the rotating shaft to facilitate maintenance
