Analysis of Commissioning and Trial Operation of Fire Smoke Exhaust Axial Fans
、
To ensure the safety of fire smoke exhaust axial fans during trial operation, these fans must be commissioned and undergo trial operation prior to use. What precautions should be taken, and how should preparations be made? The details are as follows: Installation Notes: 1. Orientation Selection: The performance of fire smoke exhaust axial fans differs from that of standard axial fans. There are strict requirements regarding the unit’s orientation. The primary azimuth of the site’s topography must be used for installation. In the event of a fire, the fire and smoke exhaust axial fan will be most effective if it is positioned to allow for continuous expansion as the fire spreads. 2. Verify Installation. Once the fire and smoke exhaust axial fan is installed, check the tightness of the main mounting points and reinforce them as needed. In the event of a fire, if the fire smoke exhaust axial fan is not properly secured, it may fall directly, rendering it ineffective for fire suppression. 3. Install protective equipment. If any part of the fire smoke exhaust axial fan is exposed to the outdoors, this is a critical consideration. Typically, rainwater may fall on the fan and, through circulation, affect internal components. Once a fire occurs, it will be difficult to achieve the desired results. When installing the unit, it is necessary to implement rain protection measures. Precautions for Commissioning: (1) Before the trial operation of the fire-rated axial flow exhaust fan, verify that all fastened components are secure and that the type and quantity of lubricant applied to all moving parts meet the requirements specified in the equipment technical documentation. (2) Any parts requiring pre-lubrication must be lubricated in advance according to specifications. (3) The rotation direction of the drive motor must match that of the pump. (4) Before the fan trial run, the pump body should be preheated to ensure uniform temperature rise, with a maximum temperature increase of 50°C per hour. There should be no temperature difference between the external high-pressure air and the process. The temperature of the hydraulic oil inlet pipeline must not exceed 40°C. By properly commissioning the fire smoke exhaust axial flow fan, selecting suitable equipment, and inspecting and maintaining the fan within the normal timeframe, operational efficiency can be improved.
