Abstract
This paper studies the feasibility of testing liquid leak rate with the vacuum method. Based on the theoretical analysis of the saturated vaporization pressure,the constant-volume pressure increment is obtained. Then by using a micro infusing system and a vacuum method,I.e. The static pressure rise method,the liquid leak testing is carried out for C2H4(OH)2 and(C2F5)3N. The results show that there is a linear relationship between the leaking liquid volume V and the pressure increment AP,as in agreement with the theoretical calculation,which shows the feasibility of the vacuum method for testing liquid leak rate. The static pressure rise method with a micro infusing system for calibration is proposed and the calculation formula is obtained. It is shown that this method is effective for testing liquid leak rate,as a tool in the liquid flowing test study.关键词
