DC cooling fans are stored and maintained in the correct way to extendDC cooling fanThe service life. The following high quality fan manufacturers will give you a detailed introduction to the maintenance methods of DC cooling fans:
1. During the operation of the DC cooling fan, it is found that the fan has abnormal sound, the motor is severely heated, the shell is charged, the switch is tripped, and it cannot be started. The machine should be shut down for inspection immediately. In order to ensure safety, maintenance is not allowed during the operation of the fan. After maintenance, it should be tested for about five minutes to confirm that there is no abnormal phenomenon before starting up.
2. The DC cooling fan should be stored in a dry environment to prevent the motor from being damp. DC cooling fan in the open storage, there should be defensive measures. The DC cooling fan shall be prevented from bumping during storage and handling to avoid damage to the fan.
3. It can only be operated under the condition that the fan is completely normal. At the same time, it is necessary to ensure that the power supply facilities have sufficient capacity and stable voltage. It is strictly prohibited to run without phase. The power supply line must be a special line and should not be powered by temporary lines for a long time.
4. The DC cooling fan should always be kept clean in the use environment, the fan surface 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 removed regularly.
5, according to the use of environmental conditions from time to time to supplement or replace the bearing grease (motor closed bearing does not need to replace lubricating grease during the service life), in order to ensure good lubrication of DC cooling fan in the operation process, refueling times not less than 1000 hours/time closed bearing and motor bearing, refueling with zl-3 lithium-based lubricating grease to fill 1/3 of the inner and outer rings of the bearing, is strictly prohibited from running out of oil.
