Let's understand the installation requirements of axial fans

Axial flow is widely used, that is, the airflow in the same direction as the blade, such as electric fans, and air conditioner external fans are axial flow fans. It is called "axial flow" because the gas flow is parallel to the axis of the wind turbine. The technical requirements for installation and commissioning of axial flow fans are introduced. The installation and commissioning of the axial flow fan, before installation, the axial flow fan should conduct a comprehensive inspection of the components.

The part is complete, the parts are connected close, no matter the rotation of the impeller Orientation and the same main part of the casing, impeller, shaft and other signs of damage, regardless of the flexible transmission. When installing, pay attention to check that there are no falling objects and debris in the chassis. In order to prevent rust and reduce the difficulty of disassembly, some joints should be coated with some grease or mechanical oil. The joints of the axial flow fan and the foundation should be adjusted to naturally match the inlet and outlet air pipe joints, and no forced connection should be made.

The components of the axial flow fan are not allowed to increase the weight of the piping, pay attention to ensure the horizontal position of the axial flow fan. Installed according to the position and size of the drawing. In order to ensure high efficiency, it is especially necessary to ensure the axial and radial clearance dimensions of the inlet and impeller. After the installation is completed, try to dial the transmission group to check whether the fixing parts are too tight or collided, and find that the position that must be adjusted too tight or collided.

The required power of the axial flow fan refers to the mechanical loss and the due safety factor under specific conditions. In order to prevent the motor from being burned due to overload, when the shaft fan is started and tested, it must be carried out under the condition of no load (close the gate in the intake pipe). If the condition is good, gradually open the gate to meet the specified working conditions. During the operation, the current should be strictly controlled, and the rated value of the motor should not be exceeded.
