How to choose an axial fan?
1. When choosing an axial flow fan, it is necessary to check whether the fan produces strong vibration and rubbing sound, which can determine whether the impeller of the axial flow fan is normal. Next, check if there are any impurities in the lubricating oil of the fan bearings and whether it needs to be replaced with new lubricating oil.
2. When selecting a suitable axial fan, we need to consider the actual usage location and occasion.
3. To determine the efficiency of axial flow fans, generally high-performance ventilation fans can meet the requirements of low noise and compact structural dimensions under set parameters, and can reduce losses to a relatively small extent by allowing airflow to pass through the designed flow channel.
4. After purchasing an axial flow fan, the fan should be observed and started during the first use to check if the blade direction is the same as the rotation mark. After the inspection is completed, a trial run of ten to half an hour should be conducted before stopping to check if the blades are loose, and if the vibration damping seat and bottom connecting bolts are loose. Only after all inspections are qualified can the fan be officially started and put into operation.
What should I pay attention to when using an axial fan?
Check whether the fan rotates flexibly and whether there is any friction phenomenon of the blades getting stuck. Are there any tools or impurities inside the fan and adjacent pipelines. If no issues are found during debugging, we can proceed with formal use.
The effectiveness of using a fan is affected by factors such as pressure, air volume, and power. How to maximize the value of a fan with limited energy depends on how we adjust it during use.
Monitor the current of the motor. The indicator of fan load is not current. In the use of fans, attention should be paid to abnormal phenomena of fans. Once there is vibration, abnormal noise or severe friction in the fan, it must be resolved in a timely manner, otherwise the effectiveness of axial flow fans will be greatly reduced.
