| Abstract: | The probe of theory analysis of scheme and application of practice are made on centrifugal main fan used in mid or small coal mine in this paper.Such measurements as modifying the blade numbers of impeller,changing the angle of inlet and outlet of blade and increasing rotational speed of impeller are adopted to meet the requirement of ventilation volume of coal mine induced by extended working-face. And these measurements have a good effect during the running in worksite. |
