What matters should be paid attention to in the operation of axial flow fan
1. When the axial flow fan is started, monitor whether there is any abnormal phenomenon in each part. If there is any abnormal phenomenon, stop the machine immediately.
2. When the axial flow fan is started, it is forbidden to enter the surge condition.
3. When adjusting the blades after the axial flow fan is started, it should be noted that the current should not exceed the rated value of the motor.
4. The normal working temperature of the shareholder bearing shall not exceed 70 ℃, the maximum temperature shall not exceed 95 ℃, the maximum temperature rise shall not exceed the ambient temperature 55 ℃, and the normal working temperature of the sliding bearing shall not exceed 75 ℃.
5. The root mean square vibration speed of the axial fan bearing shall not exceed 6.3 mm/s. For the fan whose bearing box is installed in the casing, the vibration value can be measured on the casing.
6. After the temperature rise of the main bearing is stable, the test run time shall be at least 8h. After shutdown, check the tightness of the pipeline, the clearance of the blade and the tightness of the screw and nut.
