Axial fans are very versatile, that is, the airflow in the same direction as the axis of the blades, such as electric fans, air conditioner fans, are fans operating in axial flow. It is called "axial flow" because the gas flows parallel to the fan axis. Axial fans are usually used in occasions with higher flow requirements and lower pressure requirements. The axial fan fixes the position and moves the air. The axial flow fan is mainly composed of the fan impeller and the casing. The structure is simple but the data requirements are very high.
Precautions before installation of axial fan
Before the installation of the axial flow fan: check all parts of the fan, whether the machine is complete, whether the direction of rotation of the impeller and the casing is the same, whether the connection of each part is tight. Whether the impeller, main shaft, bearing and other main mechanical parts are damaged, whether the transmission group is flexible, etc.
When installing the axial flow fan: pay attention to check the casing, there should be no tools or sundries that have fallen or left behind in the casing. In order to prevent rust and reduce the difficulty of disassembly, some joint surfaces should be coated with a layer of grease or mechanical oil. When connecting the fan and the foundation, the air inlet and outlet pipes should be adjusted so that they fit naturally. Do not force the connection, let alone add the weight of the pipe to the components of the fan. And pay attention to ensure the horizontal position of the fan.
Axial fan installation requirements: 1. Install according to the position and size shown in the drawing. In order to ensure high efficiency, it is necessary to ensure the axial and radial clearance between the air inlet and the impeller. 2. After installation, try to pull out the transmission unit to check whether it is too tight or collides with the fixed part. 3. After all installations are completed and the general inspection is passed, the fan can be tested.
