The length of the service life of the DC fan is not only the embodiment of the performance, it can make the fan better use, can protect the cooling fan and prolong its service life, so it is necessary to use some correct methods to store and maintain the cooling fan. The following is the introduction of the storage and maintenance method of the cooling fan by the Shenzhen Tian Tian mechanical and Electrical Equipment Co., Ltd.

        1. In the process of running the fan, if the fan has abnormal sound, the heat of the motor is serious, the shell is charged, the switch tripping, and can not start, it should be checked immediately. In order to ensure safety, it is not allowed to carry out maintenance in the operation of the fan. After the maintenance, the test run should be carried out for about 5 to 10 minutes to confirm that there is no abnormal phenomenon before starting operation.

        2. It can be operated only 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, the voltage is stable, it is strictly forbidden to exceed or lower the range of the product voltage, or is short of phase operation. The power supply line must be a special line, and it should not be powered by a temporary line for a long time.

       3, the working environment of DC cooling fans should be kept smooth, dry and clean. The surface of the fan is kept clean. There should be no sundries in the inlet and outlet. Regularly remove dust and other debris in the fan and pipe.

        4. Replenish or replace the lubricating grease on the bearing under the environment conditions (the motor closed bearing does not have to replace the grease in the service life period) to ensure the good lubrication of the direct current fan in the operation process, the number of refueling is not less than 1000 hours / time closed bearing and motor bearings, and the zl-3 lithium base lubrication is used for refueling. Grease filled inner and outer rings of 1/3, no oil running is strictly prohibited.

       5, DC cooling fans should be stored in a dry environment to prevent motors or motors from dampness. When DC cooling fans are stored in the open air, there should be some defensive measures. During storage and handling, we should avoid bumping or being subjected to strong external force, so as not to damage the fan.
