The service life of the DC cooling fan is not only a reflection of its performance, but also a better use of the cooling fan, which can protect the cooling fan and prolong its service life.therefore, some correct methods must be applied to store and maintain the cooling fan. Let's have the TaiWan SAN JU International Electrical Machinery CO.,LTD. technicians in Taiwan introduce how to maintain and maintain DC cooling fan .

1, DC cooling fan in the process of operation if found that the fan has abnormal sound, motor fever is serious, the shell is charged, switch tripping, can't start phenomenon, should immediately stop the machine for inspection. In order to ensure safety, it is not allowed to carry out maintenance during the operation of the fan.after maintenance, a test run should be carried out for about 5 to 10 minutes to confirm that there is no abnormal phenomenon before starting the machine for operation.

2.the fan 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 exceed or fall below the product voltage range or run without phase.the power supply lines must be dedicated lines and should not be powered by temporary lines for a long time.

3.the use environment of the DC cooling fan should always keep the air unobstructed, dry and tidy. The surface of the fan shall be kept clean.there shall be no sundries at the air inlet and outlet.dust and other sundries in the fan and pipeline shall be removed regularly.

4, according to the use of environmental conditions, the bearings are not regularly supplemented or replaced with lubricating grease ( the motor closed bearing does not need to be replaced with lubricating grease during its service life ).in order to ensure good lubrication of the DC cooling fan during operation, the number of refueling is not less than 1000 hours/time for the closed bearing and the motor bearing, and ZL-3 lithium-based lubricating grease is used to fill 1/3 of the inner and outer rings of the bearing, so it is strictly prohibited to run without oil.

5, DC cooling fan should be stored in a dry environment, to avoid the motor or motor be affected with damp be affected with damp. When the DC cooling fan is stored in the open air, it should be protected. In the process of storage and transportation, it is necessary to prevent collision or strong impact from external forces so as to prevent the fan from being damaged.

The above are some methods for maintenance and repair of DC cooling fans.if you want to know more about cooling fans, please pay attention to TaiWan SAN JU International Electrical Machinery CO.,LTD.
