Abstract: The paper introduces the necessity and working principle of the leakage monitoring equipment,and its detailed structural design, mainly including the evacuating device and the gas component analysis device of co-bulkhead tank, the evacuating pipe and the optimization of the equipment work process in launch site. At present, the two sets of equipment developed have been successfully delivered to launch site, and have participated in three space launch missions. The use of the equipment effectively ensured the safety of spacecraft and test personnel during the rocket launch mission. In the future, the equipment will continue to serve the high-density launch mission of the new generation medium carrier rocket.

Key words: monitoring equipment, leakage of hydrogen and oxygen, co-bulkhead tank of rocket
