DC cooling fanIt has been used for a long time and needs maintenance. Both DC cooling fans and AC cooling fans need maintenance, which can extend their service life and better serve you. Today, I will give you some suggestions for the maintenance of DC fans, hoping to help you maintain the cooling fan.

1. According to the use environment, the bearing of the DC cooling fan should be replenished or replaced with grease from time to time (the closed bearing of the motor does not need to be replaced during the service life). In order to ensure good lubrication of the DC cooling fan during operation, the refueling time of the closed bearing and the motor bearing should not be less than 1000 hours/time. It is strictly forbidden to fill 1/3 of the inner and outer rings of the bearing with zl-3 lithium grease.

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

3. It can only run when the DC cooling fan is completely normal. At the same time, it is necessary to ensure that the capacity of power supply facilities is sufficient and the voltage is stable. No phase operation is prohibited. The power supply line must be a dedicated line, and the temporary line shall not be temporarily used for power supply.

4. During operation, it was found that the sound of the DC cooling fan was abnormal, the motor was severely heated, the shell was charged, the switch was tripped, and it could not be started. Stop the machine immediately for inspection. In order to ensure safety, maintenance is not allowed during the operation of the DC fan. After maintenance, a trial run of about five minutes should be carried out, and the machine can be started only after confirming that there is no abnormal phenomenon.

5. The use environment of the DC cooling fan should always be kept clean and tidy, and its appearance should be kept clean. There should be no sundries at the air inlet and outlet, and dust and other sundries in the fan and pipeline should be removed regularly.
