What are the maintenance methods for DC fans?

The DC fan is stored and maintained in the correct way, which can extend the service life of the DC fan. The following Ruiapple will introduce the maintenance method of DC fan in detail:

　　1. During the operation of the DC fan, it is found that the fan has abnormal noise, the motor is severely heated, the shell is electrified, the switch is tripped, and cannot be started. It should be shut down immediately for inspection. In order to ensure safety, maintenance is not allowed during the operation of the fan. After the maintenance, a test run should be carried out for about five minutes to confirm that there is no abnormal phenomenon before starting the operation.

　　2. The DC fan should be stored in a dry environment to prevent the motor from getting damp. When the DC fan is stored in the open air, there should be defensive measures. During storage and handling, the DC fan should be prevented from bumping to avoid damage to the fan.

　　3. The fan can only operate when the fan is fully normal. At the same time, it is necessary to ensure that the power supply facilities have sufficient capacity, stable voltage, and phase loss operation is strictly prohibited. The power supply line must be a dedicated line and should not be used for long-term temporary power supply.

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

5. Irregularly add or replace lubricating grease to the bearings according to the environmental conditions of use (the motor closed bearing does not need to be replaced during the service life of the lubricating grease), in order to ensure good lubrication of the DC fan during operation, the number of refueling shall not be less than 1000 hours /Secondly seal the 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 out of oil.
