Study on the effect of impeller wear on dredging pump performance under medium-coarse sand conditions
2024
Overview
The dredging pump is the most critical dredging equipment for the cutter suction dredger, and its performance is one of the decisive factors for the cutter suction dredger productivity. Relying on the Xiamen New Airport Phase II Project, a comparative analysis of the dredging pump performance before and after impeller wear was carried out under medium-coarse sand conveying conditions. The results show that impeller wears will cause the dredging pump head to fall and performance degradation. In the range of normal construction process parameters, the larger the impeller rotational speed is or the smaller the concentration of medium-coarse sand conveying is, the more significant the decline in dredging pump performance will be. The research results can provide guidance for the cutter suction dredger pump working point adjustment and process optimization in the dredging pump wear condition.
