多级锅炉给水泵径向载荷和轴向推力实验研究

Esperimental Research on the Rakial Loads and Axial Thrusts of Multi-stage Centrifugal Pumps

对多级离心泵径向载荷和轴向推力进行了测试分析，并时该泵在三种间隙密封下径向载荷和轴向推力随流量变化而改变的趋势作了定性的研究，发现密封间隙是影响转子径向载荷的重要因素。

In this paper test analysis of radial loads and axial thrusts on multi-stage centrifugal pumpsis presented.The tendencies to that the radial loads and axial thrusts of the pump under threeannutar seals conditions vary with flow rates are also studied.Also,it is found that annularseals play an important part in radial loads of the rotor,especilly in small flow rotes.
