Prediction of Output Pressure of Dredge Centrifugal Pumps Based on Machine Learning

Dredge centrifugal pumps are extremely important equipment for CSD and TSHD in the field of dredging. It is mainly used to extract, transport and lift granular matter, so as to realize dredging and reclamation works. During the actual operation of the dredge centrifugal pump, its operation performance directly affects the efficiency of the dredgers. Relying on the operating process parameters of the CSD pump of medium-coarse sand blowing and filling project, this paper established a machine learning output pressure prediction model. By predicting the pressure output performance of different pump speed, conveying flow and conveying concentration, the operating performance of the dredge centrifugal pump is accurately obtained. The results show that the established model can accurately predict the output pressure of CSD pump of medium-coarse sand blowing and filling project, which provides an important theoretical basis for the optimization of the CSD dredging process with different conveying distances.
