实验初步研究了分子筛吸附剂在低温低压分子筛泵动态吸附过程中的作用,同时通过变化吸附温度、进气方式等参数考察其对这一吸附过程的影响,并以LDF模型对一些现象作了解释,表明适当选择操作参数可对分子筛的这种工作能力有较大的提高。
The effects of molecular sieve adsorbents on the dynamic adsorption of low-temperature and low-pressure molecular sieve pumps were studied preliminarily. At the same time, the influence of adsorbent temperature on the adsorption process was investigated, and some phenomena were explained by LDF model , Indicating that the appropriate choice of operating parameters of molecular sieve this ability to work a greater increase.
