In the automotive electric water pump, the gap height between the closed type impeller and the volute casing is inevitable due to part’s injection molding and the product assembly process. Therefore, In this study, we investigated the effect of the clearance of the pump on the performance in the same closed type impeller. Numerical analysis was performed using CFD for different the gap height models, and hydraulic performance tests were conducted using our test bench. As a result, it was confirmed that the gap height is closely related to the leakage amount inside the centrifugal pump, which greatly affects the hydraulic performance of the pump. Throughout this study, we proposed the optimal gap height. |
