Influence of Outlet Bend on Ventilator Performance
In order to solve the problem that the performance of the ventilator cannot be given full play due to the limitations of the site conditions in the working face of the coal mine production,we focus on the comparison of the corresponding performance under the length of the straight section of the ventilator connection and the forward and reverse elbow.Firstly,the test programme is formulated according to the test demand,and two test schemes are proposed;then,the effects of the length of straight pipe section and elbow connection on the full pressure of ventilator are compared,and the test conclusions obtained can guide the installation of ventilator in practical production.
