航空产品的某些零、部件和管路操纵系统,在装配之前,需要进行低温性能试验或模拟试验,以确保其在高空低温环境条件下,安全可靠的工作。 我厂自行设计与建造的低温试验室(包括低温室和预冷室,见平面图1),所采用的双级氨压缩制冷系统,经多年使用考验,工作可靠,性能稳定。它不仅较好地满足了我厂科研生
Certain zero, component and piping systems for aeronautical products require low temperature performance tests or simulation tests prior to assembly to ensure safe and reliable operation in high altitude and low temperature environments. Our own low temperature laboratory (including low temperature chamber and precooling chamber, see Figure 1) designed and constructed by our factory adopts double-stage ammonia compression refrigeration system, which has been tested for years of use, reliable in work and stable in performance. It not only satisfied our plant science students
