2021/07/20 14:48

The outstanding features of the axial flow fan are small installation depth, low noise, and high efficiency. It is especially suitable for the air flow through the heat exchanger. In addition, the axial flow fan becomes an intelligent energy saver, which is suitable for an extremely wide range of applications.

Smoke exhaust fire dampers and fire fighting components are generally installed on the pipes of mechanical smoke exhaust systems. They are usually closed. When a fire occurs, the smoke exhaust is opened. When the smoke temperature in the smoke exhaust pipe reaches 280 degrees, it is closed, and within a certain period of time Meet the requirements of smoke leakage and fire resistance integrity, and play the role of smoke isolation and fire resistance. Main materials: carbon steel, galvanized sheet, stainless steel.

Type and installation position of smoke exhaust fire damper

Normally closed smoke exhaust fire damper (normally closed, telecommunication signal on, 280 degree fuse off, or manually closed) is generally used in smoke exhaust system. One can be installed at the suction port of smoke exhaust fan. In case of fire, the smoke exhaust fan can be controlled to be opened by the fire control room. When it is closed, the smoke exhaust fan can also be interlocked.

Construction device and important role of fire damper

Release time:

2021/07/20 14:35

Fire dampers shall be installed in the air duct section close to the wall or floor slab. The fire dampers on both sides of the partition wall of the fire compartment shall not be more than 200mm from the wall surface. The pipes and their insulation materials within 2.0m on both sides of the fire dampers shall be non-combustible materials.

Material and principle of electric fire damper

Release time:

2021/07/20 13:54

Electric fire valve installed in the ventilation, air conditioning system to send, return air pipe, usually open state, fire when the pipe smoke temperature reaches 70 degrees when closed, and in a certain period of time to meet the smoke leakage and fire integrity requirements, from the role of fire.

Situation and Method of Setting Fire Damper

Release time:

2021/07/20 13:48

Fire damper and smoke fire damper in the practical application of the role of roughly the same, but there is a slight difference, so the fire damper and smoke fire damper settings need to be based on the surrounding environment.
