Reliability Assessment of Gas Supply System Based on Noise Laboratory

This thesis studies the methods of system reliability assessment for the gas supply system in noise laboratories. When the system is used in a noise laboratory, the gas is firstly imported from a gas tank and will sequentially be gone through the process of filtration, compression, purification. After the pressure is increased at a certain level, the gas is finally sent to the gas supplying outlets of each laboratory through pipelines and valves. By using of the method of reliability modeling and assessment, the quantitative reliability assessment of the gas supply system used in noise laboratories has been developed. The result provides a good basis to improve the engineering design and the reliability design, and can be extended to similar fuel supply systems. From an engineering point of view, it is an innovation that the filter in the system is identified, to be a "series - parallel mixed" structure by considering its physical structure and performance requirement.
