摘要
针对BJL5多级消防离心泵轴向力不平衡的问题设计了平衡盘装置,并优化了平衡盘的各个基本参数。应用计算流体力学(CFD)对平衡装置内的压力分布及液体流速进行了数值模拟计算,分析平衡间隙对泄漏以及平衡装置性能的影响。
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.
