Study on Aerodynamic Load of Two Stage Impeller of Mine FBD Local Fan
Taking FBD NO5.6/2×11 kW local ventilation fan as an example,a method of analyzing the pneumatic load of secondary impeller of FBD local ventilation fan for mining is introduced.The method mainly uses the relevant parameters to construct the finite element model of the primary impeller and the secondary impeller respectively,and then based on this,the corresponding conditions are set according to the operation of the FBD ventilator,so as to simulate and analyze the speed of the primary and secondary impellers.Through the simulation analysis,we can accurately understand the gas flow law and outlet velocity distribution of the two impellers inlet and outlet,so as to provide support for the optimization of the impeller structure of the ventilator.
