Axial flow fans, which are used in a wide range of applications, are fans that run in the same direction as the axis of the fan blades, such as electric fans and air conditioner fans. The reason it is called "axial flow" is that the gas flows parallel to the fan axis. Axial fans are usually used in applications that require high flow rates and low pressure requirements. Axial fans fix the position and move the air. Axial fans are mainly composed of fan impeller and casing, the structure is simple but the data requirements are very high.
Axial fan installation before precautions
Before installation of the axial fan: all parts of the fan should be checked thoroughly, whether the machine parts are complete, whether the direction of rotation of the impeller and the casing is consistent, and whether the connection of each ministry is tight. Impeller, spindle, bearings and other major parts have no damage, whether the transmission group is flexible, etc.
Axial fan installation: check the casing, there should be no tools and debris dropped into the casing and left behind. In some combination surface in order to prevent rust, reduce disassembly difficulties, should be coated with a layer of grease or mechanical oil. Fan and foundation surface, in and out of the air duct connection should be adjusted to make a natural fit, not forcibly connected, not to add the weight of the pipe on the fan parts. And pay attention to ensure the horizontal position of the fan.
Axial fan installation requirements: 1. according to the location and size shown in the drawings, to ensure high efficiency, especially to ensure that the inlet and impeller axial and radial clearance size. 2. after installation, test pull the transmission group, check whether there is too tight or collision with the fixed part of the phenomenon. 3. all the installation is complete, the total inspection qualified, before the test run of the fan.
