2. It can only operate when the fan is completely normal. At the same time, it is necessary to ensure that the capacity of the power supply facilities is sufficient and the voltage is stable. It is strictly prohibited to operate without phase. The power supply line must be a special line. It is not allowed to use the temporary line for long-term power supply. It is necessary to have circuit protection devices, such as the installation of the missing item protection switch, leakage switch, etc.
3. During the operation of axial flow fan, it is found that the fan has abnormal noise, the motor is seriously heated, the shell is electrified, the switch trips and cannot be started, etc., so it shall be stopped immediately for inspection. In order to ensure safety, it is not allowed to carry out maintenance during the operation of the fan. After maintenance, it is necessary to conduct a test run for about five minutes, and then restart the fan after confirming that there is no abnormal phenomenon.
4. Supplement or replace the lubricating grease for the bearing irregularly according to the service environment (the lubricating grease does not need to be replaced for the closed bearing of the motor within the service life).
5. Axial flow fans shall be stored in a dry environment to avoid motor damp. When the axial flow fan is stored in the open air, there should be defensive measures. In the process of storage and handling, the fan shall be prevented from bumping, so as to avoid damage to the fan.https://www.ck-stone.com/
