【摘要】：低温绝热气瓶作为一种储运低温液体的特种容器,因其充装率高、使用方便、使用成本低等特点,逐渐地取代了传统高压钢制气瓶,被广泛的应用在工业生产、医疗和冶金等多个行业。近年来,由于其使用量逐渐增多,为确保低温绝热气瓶在使用过程中的安全性和可靠性,因此需要进行定期检验。本文根据低温绝热气瓶产生问题及失效模式的主要原因,结合传统手工检验的工艺流程和气瓶检验的国家标准,采用检验过程自动化和检验信息网络化的方法,设计了一套低温绝热气瓶智能化检验流程及其检验系统,主要的研究内容有:(1)以江苏省低温绝热设备产品质量监督检验中心的低温绝热气瓶检验项目为研究背景,对低温绝热气瓶智能化检验系统进行了详细的需求分析,给出了低温绝热气瓶智能化检验系统的具体检验工艺与检验流程,对低温绝热气瓶的智能化检验方案进行了设计。(2)针对低温绝热气瓶智能化检验系统的检验流程,重点研究了气密性试验、真空度检测、静态蒸发率测试三个关键工艺,采用组态王、SQL Server数据库等软件设计并实现了气密性试验子系统、真空度检测子系统和静态蒸发率测试子系统,实现了气密性、真空度和静态蒸发率的智能化检验和信息管理。(3)针对低温绝热气瓶智能化检验系统中的静态蒸发率检测时间较长的问题,为了缩短静态蒸发率测试的时间、提高检验效率,分别采用一元线性回归和GM(1,1)模型进行建模,对静态蒸发率快速检验方法进行了探索,通过实测数据分析,验证了此方法的可行性。
[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.
