Measures to ensure the safe operation of axial-flow fan

In order to ensure the safe operation of the axial flow fan, the structure of the fan shall be reasonable, the specified and installed quality shall meet the requirements, and all operating conditions shall be guaranteed, and it will not fall within the unstable working area. To do this, it is necessary to select the parameters of the fan properly and adopt the reasonable adjustment method and the starting measure.

The parameter selection of adjustable axial flow fan with moving blade should make the rated working condition point located in the center of the highest efficiency area, so as to ensure the efficient operation at full load and avoid entering the unstable zone at low load. In addition, the angle indication of wind pressure and air volume or blade should be seen in the control room, which is the first condition to ensure the safe operation of the fan.
