CFD-based Simulation Design of Axial Force Balance Disk Parameters of Forest Fire Fighting Pumps

In view of the problem with the axial force of BJL5 Multi-stage Fire Fighting Centrifugal Pump,a balance disk is designed,with each of its parameters optimized.Computational fluid dynamics(CFD) is adopted to conduct numerical simulation calculation of the pressure distribution and fluid speed inside the balance device in order to analyze the influence of balance gap on the leakage and the performance of the balance device.
