Abstract:

Local fans in underground coal mines are now mainly axial fans. The setting an d twist angles of the axial fan blade directly affect the velocity of the air passing through the fan, that is, affect the flow and thrust pressure of the fan. The velocity components of the air at the entry and exit points of the blades are normally determined by geometric methods. Due to the cu rved blade profile in space, the survey of velocity components at some characteristic cross-sections does not accurately represent the average velocity of the air leaving the blades. In order to simplify and reduce the calculation volume and quickly determine the flow and air pressure passing through the fan, conduct simulation for the local fan by building 3D models and assembly for quick adjustment. Quickly set the blade angle to simulate the flow of air through the fan. This method allows the designer to quickly and intuitively determine the blade angle as well as the fan setting angle.
