我们的动水腐蚀实验室配备有6套动水腐蚀实验回路。在过去几年里完成了大量的结构材料筛选试验,积累了一些回路建设和运行的经验。本文报道了典型的动水回路的结构以及主要部件,如循环泵、加热器、稳压器和阀门等器件的改进。还介绍了提高回路系统密封性和系统除氧方面的经验。过去我们主要研究铝,发现动水对铝的腐蚀的影响特别严重。 Our moving water corrosion laboratory is equipped with 6 sets of moving water corrosion test circuit. In the past few years, a large number of structural material screening tests have been completed, accumulating some experience in circuit construction and operation. This paper reports the structure of a typical hydrodynamic loop and the improvements of major components such as circulation pumps, heaters, regulators and valves. Also introduced to improve the tightness of the loop system and system oxygen experience. In the past we mainly studied aluminum and found that hydrothermal water had a particularly serious impact on the corrosion of aluminum.
