一种深海气密采水器的高压仓密封性能检测试验研究

Experimental Research on the Tightness of a Gas-tight Sampler in High-pressure Chamber

深海海水中的气体研究是当前海洋科学研究的前沿课题,浙江大学流体传动及控制国家重点实验室研制开发出一套新型深海气密采水器,经过海上试验验证其密封性能优于非气密性采水器。但是对于其密封性能,并未给出严格的证明。论文通过理论分析设计出严格模拟海上试验环境的高压仓密封性检测试验,证明了该气密采水器回收过程中气密性能良好,有力验证了该气密采水器的可行性和可靠性并为其进一步改进提供依据和参考。

In ocean science, the study of dissolved gases in deep-sea water is something ot disciplinary h-ontaer, on this 19asls, a new-type gas-tight sampler, which is proved to be better in gas-tightness than classic sampler, has been developed in State Key Laboratory of Fluid Power and Control, zhejiang university. But there is not a rigid proof on the degree of gas-tightness. So on the basis of theoretical analysis, the author designs a experiment to test the tightness in high-pressure chamber which is used to simulate the environment in the sea, through the test, the author proved the tightness of the gas-tight sampler is reliable, also the experiment vituessed the feasibility of the gas-tight sampler and lay the foundation for the next improved design.
