摘要

摘要: 将闭式氦气透平循环与高温气冷堆相结合，是未来高温气冷堆发电技术的潜在发展方向之一。高速机械性能试验是设计与研制氦气透平压气机组的关键环节，能考验电磁轴承支承的透平压气机组的机械旋转性能，为未来机组顺利与反应堆相连接进行热态运行奠定基础。本文设计并分析一种在密闭空间内低密度下进行高速机械性能试验的方案，建立试验系统热工模型，获得了低密度下透平压气机组性能，得到了系统温度场分布，从而确定电机定子温度为试验系统的温度限制条件。对密闭空间试验系统的传热和流动分析表明，在低密度下，存在合理的压力调节范围使得系统散热能力高于发热能力，从而保证整个系统的安全运行，确定了低密度方案的可行性。

Abstract: It’s a potential developing direction for power generation of high temperature gas-cooled reactor combined with helium turbine closed cycle. The high speed mechanical performance test plays a key role in design and development of helium turbine system. It would verify the mechanical performance of turbine-compressor which was supported by active magnetic bearings. The results would provide basis for normal operation while helium turbine system is successfully connected with reactor in the future. A high speed mechanical performance test of helium turbomachinery was designed and analyzed. The rotor was supposed to be arranged in an enclosed vessel and low density environment inside the vessel can be acquired. By analyzing the preliminary thermo-hydraulic characteristics of test system, turbomachinery performance under low density was achieved and temperature distribution was estimated. The results indicate that the maximum temperature of motor’s stator is the temperature limit of test system. The thermo-hydraulic analysis shows there exists a certain pressure adjusting range to achieve the safe operation of test and it ensures the feasibility of this low density plan.
