摘　　要：为满足某项目小体积液氢储存需求,研制了容积为4 m^(3)的小型液氢储罐。该液氢储罐罐体采用高真空多层绝热结构,内外容器间支撑结构采用了两端金属支撑结构并采用Ag400吸附剂控制夹层真空度。在液氢储罐主体材料方面,储罐内容器采用S31608不锈钢,储罐外壳采用S30408不锈钢,并采用“等离子弧与钨极氩弧”(即“PAW+GTAW”)复合焊接工艺、实时成像及悬臂式套装等制造工艺。装载液氮工况下的测试结果表明,设计的小型液氢储罐罐体夹层真空度为3.5×10^(-3)Pa,静态日蒸发率为0.82%。In order to meet the storage requirements of small volume liquid hydrogen of a project,a 4 m^(3) small-scale liquid hydrogen storage tank is developed.The tank body adopts high vacuum multilayer insulation structure,the support structure between inner and outer containers adopts metal support structure at both ends,and Ag400 adsorbent is used to control the vacuum degree of interlayer.In terms of main material,the inner container adopts S31608 stainless steel,the shell adopts S30408 stainless steel,and PAW+GTAW plasma welding,real-time imaging and cantilever assembling manufacturing process are adopted.The test results under the condition of loading liquid nitrogen show that the vacuum degree of the body interlayer of the designed smallscale liquid hydrogen storage tank is 3.5×10^(-3)Pa,and the static daily evaporation rate is 0.82%.
