What are the maintenance methods for cooling fans?
The cooling fan should be stored and maintained in a correct way to extend the service life of the cooling fan. The following cooling fan manufacturer-Ruiapple will introduce the maintenance method of DC cooling fan in detail:
1. During the operation of the DC cooling 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, it is not allowed to perform maintenance while the fan is running. After the maintenance, a trial run should be carried out for about five minutes to confirm that there is no abnormal phenomenon before starting the operation.
2. The DC cooling fan should be stored in a dry environment to prevent the motor from getting damp. When the DC cooling fan is stored in the open air, there should be defensive measures. During storage and transportation, the DC cooling fan should be prevented from bumping to avoid damage to the fan.
3. The fan can only be operated under normal conditions. At the same time, it is necessary to ensure that the capacity of the power supply facilities is sufficient, the voltage is stable, and the lack of phase 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 cooling 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 air inlet and outlet, and the dust and other debris in the fan and pipeline should be cleaned regularly.
5. Irregularly add or replace grease to the bearing according to the environmental conditions of use (the motor enclosed bearing does not need to replace the grease during the service life), in order to ensure good lubrication of the DC cooling fan during operation, the number of refueling shall not be less than 1000 The bearings and motor bearings are closed per hour, and 1/3 of the inner and outer rings of the bearing are filled with zl-3 lithium-based lubricating grease. Running without oil is strictly prohibited.
