Causes and Solutions for Surge of EC Axial Fan?
What is surge? Simply put, it is similar to human asthma. Due to the periodic wind and backflow of EC axial fans, once more serious surge occurs.
It will cause fatigue damage to the bearings and blades of the fan and cause accidents.
This leads to a decrease in safety.
Generally speaking, the occurrence of EC axial fan surge will be accompanied by frequent current swings, reduced outlet air pressure, increased noise, and increased vibration.
So what are the reasons for the surge? What are the solutions?
The main reason for the surge of the EC axial fan is that the equipment is running in a non-operating work area.
Or the air duct of the fan is blocked, the opening of the air duct baffle is not enough, and the air duct baffle is not opened, resulting in excessive system resistance.
Normally, when the working area of the EC axial flow fan is on the right side of the dividing point, the equipment will operate relatively stable, but when the equipment load is relatively low, the operation will be unstable, and the pressure head of the equipment will drop below the pipe.
The pressure in the road, the pressure head will cause the airflow to start to reverse in the opposite direction and pour it back into the fan from the air duct.
Backflow airflow will reduce the air volume in the duct system, which will lead to a drop in pressure in the duct, but because the EC axial fan still continues to run.
So that the flow of the EC axial fan continue to output, but with the rise in pressure, in order to be able to balance with the pressure in the duct, the work point needs to be adjusted, which will lead to wind backflow again, causing EC axial fan wheezing.
To solve the problem of EC axial fan wheezing, you need to run the EC axial fan at a stable working point, not to let it in the unstable area can be.
A simple solution to the problem of EC axial fan surge is to quickly open the dynamic leaves of the surge fan or to increase the processing and frequency of the EC axial fan.
