摘要：依据美国PVRC、ASTM、欧美EN和我国GB等标准规范,开发一种核级密封件性能检测系统。该系统由液压加载系统、测试单元、试验介质给定系统和数据采集分析系统构成,可通过测量密封件在不同温度、压紧力和试验介质情况下的压缩回弹性能、蠕变松弛性能或密封性能,全面评价密封件的总体性能。该系统载荷测量精度为10 N,变形测量精度为1μm,泄漏量测量精度为氦气1.0×10^(-11)Pa·m^3/s,能够检测密封件在室温至450℃范围内的总体性能,解决了高温条件下核级密封件性能检测技术难题。
Based on the standard or specification of the United States PVRC,ASTM,Europe EN and Chinese GB, a seal performance testing device was developed for gaskets used in nuclear power plant.The device is consisted of hydraulic load?ing system, test element, test medium given system and data acquisition&analysis system,which can evaluate the overall performance of gaskets through measuring the compressibility and recovery,creep performance,stress relaxation,seal ability of gaskets under different temperature, pressure and test medium. The device’ s measurement accuracy of load is 10 N, deformation is 1μm, helium leakage is 1. 0×10-11 Pa·m3/s. The device can be used to detect the overall performance of gaskets under room temperature to 450 ℃, which successfully solves the technical problem of seal performance testing of nuclear grade gaskets under elevated temperature.
