What are the key points for maintaining high-temperature boiler fans?

What are the main points to consider when maintaining high-temperature boiler fans? This post addresses that very question. What is the answer to this question? The details are set out below. 1. It is necessary to open the air duct for the high-temperature boiler fan during operation. When the air flow is very low, the axial fan may experience power overload. Please take care not to operate the fan for extended periods in an environment with insufficient air supply, such as when seals or valves are completely closed. Ideally, the current should be monitored regularly. 2. Before using a high-temperature boiler fan, it is necessary to test it. This process ensures that the fan operates without issues and maximises its effectiveness. 3. If the high-temperature boiler fan has not been used for an extended period and is to be used again, first confirm that all components of the fan are securely fastened. If any looseness is detected, tighten them immediately to prevent fan components from becoming loose during the test run, which could render the fan inoperable. 4. Before starting the high-temperature boiler fan, any obstructions to the rotation of the fan or ductwork must be removed first. 5. Following the trial run of the high-temperature boiler fan, if it is to be put into regular service and no issues are found, the fan’s operation must be monitored regularly. Should any abnormalities be detected, stop the fan immediately and investigate.
