摘要
以高压冷气为弹射能源的氮气作动系统具有清洁、使用维护方便、成本低、使用寿命长等优点。通过对氮气投放系统中超高压电磁阀的故障模式影响及危害性进行分析,找出了影响超高压电磁阀可靠性的因素,并分析其机理,从设计、工艺、装配、使用等方面采取措施,提高了电磁阀的可靠性。
Launch system based on nitrogen resource is involved in the airborne ejection process due to its low cost,maintainability and long life cycle.The superhigh pressure-solenoid valve is a key part in the whole system and its reliability is critical.In this paper,the fault model and its influence and harmfulness of superhigh pressure-solenoid valve during the airborne ejection process with nitrogen resource is analyzed so that the influence factor of reliability of superhigh pressure-solenoid valve is obtained.The underlay law is also given.Based on the results,the improvable method for reliability is proposed according to the design,process planning,and assembly as well as work aspects.The reliability for superhigh pressure-solenoid valve can be improved due to those analysis results.
