How to Maintenance of axial fan ?

1. The use environment should always be kept clean, the surface of the fan should be kept clean, there should be no debris in the inlet and outlet, and the dust and other debris in the fan and pipe should be removed regularly.

2. The fan can only be operated under completely normal conditions, and the power supply facilities should be ensured to have sufficient capacity and stable voltage. Defective operation is strictly prohibited.

3. When the fan is found to have abnormal sound, serious motor heating, live shell, switch trip, unable to start and other phenomena during operation, it should be stopped immediately for inspection. In order to ensure safety, maintenance is not allowed during the operation of the fan. After maintenance, test run should be conducted for about five minutes to confirm that there is no abnormal phenomenon before starting operation.

4. Add or replace lubricating grease to bearings irregularly according to the operating environment (motor closed bearings do not need to replace lubricating grease during their service life). In order to ensure good lubrication during the operation of the fan, fill bearings and motor bearings with zl-3 lithium based lubricating grease for at least 1000 hours per time. It is strictly prohibited to run without oil.

5, the fan should be stored in a dry environment, to avoid the motor moisture. Defensive measures should be taken when the fan is stored in the open air. In the storage and handling process should prevent the fan bump, so as to avoid damage to the fan.

Axial fan is very widely used. It is the air flow in the same direction as the axis of the wind blade, such as the electric fan. The fan outside the air conditioner is the axial flow fan. It is called "axial flow" because the gas flows parallel to the fan axis. Axial fans are usually used in situations where the flow requirement is high and the pressure requirement is low. Axial fans hold the air in place and move it. Axial fan is mainly composed of fan impeller and casing, simple structure but very high data requirements.
