摘要
为实现密闭舱内的温湿度控制,液压回路加注和再加注工作是众多航天器均不可或缺的必备工作之一,因加注的技术流程复杂,针对不同的加注对象需确定的指标参数较多,本文分析了各指标参数确定的理论依据,给出了工质脱气和液压回路抽真空等指标制定的原则和方法,对后续工作有良好的借鉴和指导意义。
To realize the cabin temperature and humidity control of airtight,filling and refilling for hydraulic loop of numerous spacecraft are one of the indispensable essentials.Filling process is very complex.Many of the indicators and parameters need to be determined for different filling objects.In this paper,the target parameters were analyzed to determine the theoretical basis.The principles and methods to specify the indicators for refrigerant degassing and vacuum pumping for inner loop are given.The work has a good reference and guidance for follow-up.
