摘要
本文对国内正在研制的新型落锤动标装置的密封部分进行了分析 ,选择了铅和测压油 (一种混合油 )作间隙密封的密封介质 ,并在 2 0 0～ 70 0MPa的高压下进行了实验 ,对结果进行了分析和讨论 ,得出了铅的耐高压和密封性能较好的结论。
In this paper, a sealing part in pressure generator , which is the key part of new type of falling hammer dynamic pressure calibrator being researched in our country , is analyzed Lead and measuring pressure oil (a kind of mixed oil) are used as sealing medium in crack sealing, and an experiment is done under the high pressure from 200MPa to 700MPa The result is analyzed and discussed, and a conclusion is drawn that the sealing property of lead under high pressure is good
