【摘要】 液体静压支承技术可以很好地解决多级离心泵轴向力的平衡问题。本文以DM360型泵轴向力的液体静压支承平衡为例，对扭板节流静压支承的设计计算和动静态特性分析进行了较为详尽的阐述，推导出支承结构的设计参数和公式，讨论了各种主要因素(油液的粘度、油液的可压缩性、扭板变形系数、供油压力、支承间隙)对支承动态特性的影响，给出了一些结论。同时，在考虑油液粘度变化和油流惯性的情况下，分析了支承缝隙中流体的流动特性，并进行计算机仿真和实验验证，这为静压支承在轴向力平衡中的进一步合理设计和应用提供了理论参考。更多还原

【Abstract】 Hydrostatic bearing can solve the equilibrium problem of axial force of multistage centrifugal pump satisfactorily. Taking the hydrostatic equilibrium of axial force of pump DM360 as the example, this paper elaborates design calculation and dynamic-static characteristic analysis of hydrostatic bearing with twisting plate throttle, derives design parameters and formulas of bearing structure, discusses effects of various main factors (oil viscosity, compressibility, distortion coefficient of twisting plate, pressure of oil source, and bearing clearance) on dynamic characteristic, and obtains some conclusions about the application of hydrostatic bearing in engineering practice. And at the same time, considering the situation of varying oil viscosity and oil-flow inertia, this paper analyzes flowing properties of fluid in bearing clearance, which provide theory reference for more reasonable design and application of hydrostatic bearing in the equilibrium of axial force, and then carries out computer simulation and experiment verifying.更多还原
