Maintenance of axial flow 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 pipeline should be regularly removed.
2. The axial fan can only be operated when it is completely normal. At the same time, it is necessary to ensure that the power supply facilities have sufficient capacity and stable voltage. Defective operation is strictly prohibited. The power supply line must be a dedicated line, and temporary lines should not be used for long-term power supply.
3. During the operation of the axial fan, if it is found that the fan has abnormal sound, the motor is seriously heated, the shell is electrified, the switch is tripped, and it cannot be started, etc., it should be stopped immediately for inspection. In order to ensure safety, maintenance is not allowed during the operation of the fan. After the maintenance, a trial operation should be carried out for about five minutes to confirm that there is no abnormality before starting the operation.
4. According to the environmental conditions of use, the bearing should be supplemented or replaced with lubricating grease from time to time (the closed bearing of the motor does not need to be replaced with lubricating grease during its service life). For sub-closed bearings and motor bearings, fill 1/3 of the inner and outer rings of the bearing with zl-3 lithium-based lubricating grease; it is strictly forbidden to run without oil.

5. The  axial fan should be stored in a dry environment to prevent the motor from getting wet. When the fan is stored in the open air, defensive measures should be taken. During storage and handling, the fan should be prevented from bumping to avoid damage to the fan.
