Optimize the design and performance prediction of axial fan to establish the mathematical model of the merits of the results have a critical impact. Currently pipeline explosion in Shanxi axial fan, axial fan description of the mathematical model of the machine lost more analysis based on each runner loss that may arise with a simple formula to express the relationship between the flow field and the loss of Shanxi mine axial fan model then the superposition of losses, in order to carry out computing performance. Axial fan with the model is according to their different collector duct type routine to perform with. Different types of axial fans Shanxi mine explosion-proof axial fans, just in case, confirmed with four different models. A type: free import and export freely, B-free import and export of C-type vortex tube inlet and free outlet, D-shaped swirl inlet and outlet pipes, in order to have the conditions at the exit of A type. Shanxi Coal Mine in Shanxi mountain original blower is provided by a limited liability company with a primary blower explosion-proof axial fan axial fan _ _ Shanxi Hill. Shanxi nagorye Blower Co., Ltd. (www.sxgfj.cn) (www.sxfjgs.com) strong, credible, Xinzhou in Shanxi fans, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead nagorye blower into the brilliant and you work for a better future!
