摘　　要：为了研究高密度聚乙烯(PE-HD)管的耐氯氧化性能,基于ASTM F2263标准,设计了一种封闭循环试验系统,可在流动状态下通过改变温度、压力和有效氯含量加速试样的氧化失效。结果表明,该系统可独立测试24根DN 20的PE-HD管状试样,可编程逻辑控制器(PLC)作为控制主机可以控制管路的压力、温度和流量,再加上耦合各传感器,可实现可视化的人机界面,内置的报警系统可保证试验的安全可靠。本试验系统可用于对PE-HD输水管的耐氯氧化性能进行评价。To investigate the chlorine oxidation resistance of high density polyethylene(PE-HD)pipes,a closed cycle test system was designed on the basis of the ASTM F2263 standard.The test system accelerated the oxidation failure of samples through changing the temperature,pressure,and available chlorine content under the flowing condition.The results indicated that the system could measure the 24 DN 20 PE-HD tubular samples independently,and the programmable logic controller could be used as a control host to control the pressure,temperature,and flow of the pipelines.Furthermore,the visual human-computer interface could be realized through coupling with various sensors,and the built-in alarm system could ensure the safety and reliability of the test.Therefore,the test system can be used to evaluate the chlorine oxidation resistance of the PE-HD pipes.
