摘要
泵在工作过程中存在着轴向力,影响泵的可靠性及使用寿命。利用计算流体力学方法,计算泵在不同转速下的性能参数,与试验结果相近,证明该计算模型、计算方法相对可信。进而对该模型开不同直径的平衡孔以泄压平衡轴向力。结果表明:平衡孔能够有效降低轴向力,同时对其他性能的影响较小。并选取直径2 mm平衡孔作为优选方案。
When pump working, an axial force will be generated, affecting reliability and life time of pump.Using computational fluid dynamics method, the performance parameters of the pump at different speeds were obtained.The calculation results were very close to test results.It was proved that the simulation mode and computational method are relatively reliable.On the pump, balance holes with different diameter were cut to reduce axial force.The results show that the balance hole can effectively reduce axial force, at the same time it has little effect on the other properties of pump.At last, for the balance hole the optimum diameter is 2 mm.
