18L碳纤维缠绕气瓶的研制

Development of carbon-fiber gas cylinder of 18 liters

目的设计一种18 L碳纤维缠绕气瓶,专门用于在急救、转运潜水疾病、肺气压伤病员过程中,为便携式医疗加压舱提供呼吸气体。方法通过气瓶内胆和缠绕设计,确定相应的尺寸、质量和缠绕层数,再通过水压试验、疲劳试验和爆破试验验证其技术指标。结果气瓶容积18.1 L,质量9.86 kg,长度782 mm,外径201 mm。水压试验压力30 MPa、保压60 s,残余变形<5%;疲劳试验压力20 MPa,1 500次;实际爆破压力88.4 MPa。结论根据相关标准进行气瓶试验,试验情况满足《气瓶安全监察规程》的要求。

Objective To design and develop a carbon-fiber gas cylinder of 18 liters, which could provide breathing gas to a portable medical chamber in the first aid and transfer of casualties with diving diseases and pulmonary barotrauma. Methods The di- mension, weight and layers of winding were determined, through the design of the winding method and the interior of the gas cylinder. Then a series of tests, such as water pressure test, fatigue test and demolition test were conducted to demonstrate that all the technical specifications were met. Results The capacity of the cylinder was 18.1 L, weight 9.86 kg, overall length 782 mm and outside diameter 201 mm. The pressure of water test was 30 MPa, which was maintained tbr 60 s. Residue distortion was 〈5% and the pressure for fa- tigue test for a succession of 1 500 times was 20 MPa, and actual demolition test pressure was 88.4 MPa. Conclusion Related cylinder tests were conducted in accordance with corresponding criteria, and test results indicated that all the criteria specified in（（the Safety Su- pervision Procedures of Gas Cylinders〉〉were met.
