Usage Methods of Fire Ventilation Cabinet Centrifugal Fans
Although the content is not yet fully detailed, considering the existing foundation, it is not difficult to understand and master this information. If there is any delay, we can begin learning immediately. It is hoped that through this content, you can gain something and improve your learning methods.
Origin of the Name “Fire Ventilation Cabinet Centrifugal Fan” The reason why the fire ventilation cabinet centrifugal fan is named a “centrifugal fan” is due to the spiral movement of the air, which radiates outward from the center of the fan. Compared to the ventilation cabinet centrifugal fan, the airflow in its impeller flows axially, showing a significant structural difference.
Difference Between Fire Ventilation Fans and Centrifugal Fans The fire ventilation cabinet centrifugal fan differs from ordinary centrifugal induced draft fans, so we can clearly conclude this. Additionally, boiler fans are mainly used in boiler equipment, and their design and use have unique requirements.
Causes and Solutions for Vibration in the Fixed Parts of Fire Ventilation Cabinet Centrifugal Fans During operation, the fixed parts of the fire ventilation cabinet centrifugal fan may generate mechanical vibrations. Here are the specific causes and corresponding solutions:
(1) Too Light a Foundation or Small Base Area: If the cement foundation of the fire ventilation cabinet centrifugal fan is too light or the base area is too small, it may cause equipment vibration. The solution is to strengthen the foundation or adjust the installation position of the fan.
(2) Loose Anchor Bolts or Unstable Frame Connections: If the fan’s anchor bolts are loose or the frame connection to other components is not secure, vibration will occur. Tighten the anchor bolts or check the couplings to ensure secure connections.
(3) Low Foundation and Rotational Stiffness: If the foundation stiffness or rotational stiffness of the fan is insufficient, the vibration will increase. In this case, the foundation must be reinforced to improve its stiffness and reduce vibration.
(4) Issues with Water Inlet and Outlet Pipelines Installation: Check if the water inlet and outlet pipelines of the fire ventilation cabinet centrifugal fan are equipped with supports or flexible connections, and whether other equipment foundations are too close to the fan’s foundation. If problems are found, supports or flexible connections should be installed, or the foundation stiffness should be enhanced. Additionally, ensure that the distance between other equipment foundations and the fire ventilation cabinet fan foundation is appropriate to avoid unnecessary interference.
By taking these measures, mechanical vibrations in the fire ventilation cabinet centrifugal fan can be effectively reduced or eliminated, ensuring stable operation and long-term use of the equipment.
