Impeller Finite Element Analysis of Extractable Explosion-Proof Contra-Rotating Axial Fan for Mine Local Ventilation FBDC

Abstract:

To improve the impeller safety and reliability of extractable explosion-proof contra-rotating axial fan for mine local ventilation, Extractable Fan FBDC№9.0/2×30 was taken as the research object, and an approximate three-dimensional finite element computation model was built by using ANSYS software. The stress and displacement were calculated, too. By testing, the fan works stably. The air quantity is 655-978 m3/min, total pressure, 3443-412Pa, static pressure, 3314-118Pa. And the highest static pressure efficiency is up to 70.35%, A-weight Specific Sound Level is 17.5dB. Furthermore, the intension and stiffness of the impeller meet requirements. Sample test and field using show that the computation and the model of this impeller are right. Through reasonable design, the impeller of contra-rotating axial fan with equally-thick circular arc blade profile and ordinary hot-rolling low-carbon steel blades has the intension and the stiffness which meets demands, and the air performance reaches higher level.
