随着我国科学技术的不断进步,低温泵机在技术上得到了不断的改善和发展,但是在实际的工作中,出现了诸多的问题,尤其是低温泵在运行过程中常常产生机械密封泄漏现象。本文主要通过结合低温泵机的工作原理,分析低温泵在运行过程产生机械密封泄漏现象的原因,通过机械密封失效的各种形式,从而具体提出了低温泵机械密封泄漏问题的解决策略。 With the continuous improvement of our country’s science and technology, the cryogenic pump has been continuously improved and developed technically. However, in practical work, many problems have appeared, especially the cryogenic pump often produces mechanical seal leakage during operation . Based on the working principle of the cryogenic pump, this paper analyzes the causes of cryogenic pump mechanical seal leakage during operation, and through the various forms of mechanical seal failure, the solution to the mechanical seal leakage problem of cryogenic pump is put forward.
