[Abstract]:As a special container for storing and transporting low temperature liquid, low temperature adiabatic gas cylinder has been widely used in industrial production because of its high filling rate, convenient use, low cost and so on. In recent years, because of its increasing use, in order to ensure the safety and reliability of cryogenic adiabatic cylinders, So it is necessary to carry out periodic inspection. According to the problems caused by low temperature adiabatic gas cylinders and the main causes of failure modes, combined with the traditional manual inspection process and the national standard of gas cylinder inspection, By using the method of automation of inspection process and networking of inspection information, a set of intelligent inspection process and inspection system for low temperature adiabatic gas cylinder are designed. The main research contents are as follows: (1) based on the research background of the low temperature adiabatic cylinder inspection project of Jiangsu Province low temperature adiabatic equipment product quality supervision and inspection center, the detailed demand analysis of the low temperature adiabatic cylinder intelligent inspection system is carried out. The concrete inspection technology and inspection flow of the intelligent inspection system for the low temperature adiabatic cylinder are given. The intelligent inspection scheme of the low temperature adiabatic cylinder is designed. (2) the inspection flow of the intelligent inspection system for the low temperature adiabatic cylinder is designed. In this paper, three key technologies of air tightness test, vacuum test and static evaporation rate testing are studied emphatically. The subsystem of air tightness test is designed and implemented by using Kingview SQL Server database and other software. The vacuum measurement subsystem and the static evaporation rate test subsystem have realized the airtightness. To solve the problem of long detection time of static evaporation rate in the intelligent inspection system of low temperature adiabatic gas cylinder, in order to shorten the test time of static evaporation rate and improve the inspection efficiency, The linear regression model and GM-1) model are used to model the fast test method of static evaporation rate. The feasibility of this method is verified by the analysis of measured data.
