Maintenance method of cooling fan

The cooling fan is an important component in the cooling system of mechanical equipment. Once damaged, it will cause additional maintenance costs and cause the machine to fail to work. Therefore, in the daily use process, certain maintenance of the cooling fan is required to extend the working life of the cooling fan.

 

Maintenance method of cooling fan


Maintenance method of cooling fan:

 

1. The cooling fan should always be kept tidy 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 removed regularly.

 

2. 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.

It should be shut down immediately for inspection. In order to ensure safety, maintenance is not allowed during the operation of the fan. After the maintenance, a test run should be carried out for about five minutes to confirm that there is no abnormal phenomenon before starting the operation.
