| Abstract: | The measurement of rev of two impellers is an important part of performance testing and study of the counter-rotating fan,but yet there has no an effective rev measuring method on site.Through the relationship between the pulsation frequency of the pressure in the tip of the impeller blade and the impeller rev,the paper elaborates the principle and the method of calculating the impeller rev by measuring the pulsation frequency of the pressure in the tip of the impeller blade,and then field tests are carried... |
