| Abstract: | Flowrate measurement is a crucial operation in large pump unit testing and operation optimizing and usually it is time-consuming, costly and less precise. In this paper, the flowrate was determined by a 5-hole globe probe system. Measuring section and points were analyzed and fixed and the flowrate was computed by integrating according to the axial flow velocity distribution of the section. The factors influencing measuring precision and the methods improving the precision were researched respectively. The measuring method has been successful applied to 8 large pump units in 5 pumping stations of Jiangsu Province. The results indicate that the method is simple, convenience, ease and non-time-consuming and its precision is superior to 2%. |
