- 摘要:
- 煤油加注系统是大推力运载火箭动力系统试验台的重要组成部分，其主要功能是连续、可靠、准确地向箭上贮箱加注煤油。按照系统要求对大流量煤油加注工艺进行了分析，提出了根据管路特性曲线进行离心泵选型的依据。通过对节流控制、旁路调节及变频调速调节等几种流量控制方法进行比较，指出采用变频调速方法进行煤油加注的优点及可行性。在地面试验系统中使用变频泵已完成数次动力系统煤油加注试验，各次加注状态正常，加注流量稳定，满足各项技术要求。采用变频泵进行煤油加注具有流量跨度大，控制精度高，流量切换灵活及调节响应快的优点，是确保煤油加注系统安全、稳定、长期运行的有效途径。
- Abstract:
- The kerosene filling system is an important part of test-bed for large thrust rocket dynamical system. It supplies kerosene continuously, reliably and accurately to the rocket tank. The selection principle of centrifugal pump is determined according to the system requirement of large flow and pipeline characteristic curve. Through the comparison among three methods of throttle control, bypass regulation and frequency control, it is pointed out that the strong points and feasibility of the frequency control method are the most. The test of several dynamical systems has been accomplished by variable frequency pump, in which every kerosene filling state is normal, filling flow is stable, and the results can satisfy the requirements of the ground test system. The variable frequency pump possesses big flow span, high control accuracy, flexible flow switch and fast modulating response. It is an effective way to ensure the kerosene filling system is secure, steady and
