Based the numerical simulation for sphere tank with defects, fracture safety assessment and stress strength verification are done under the cases of working pressure and over pressure. 在数值模拟计算含缺陷球罐应力场的基础上,对含缺陷球罐在工作压力和超压两种工况下进行了断裂安全评定和强度校核。
Safety working pressure rating 额定安全工作压力值
To set the cracking pressure and the discharge pressure of the safety valves correctly, the design pressure of tanks should be determined by the specification according to the maximum working pressure; 为正确设置储罐安全阀的开启压力和排放压力,必须根据储罐的最高工作压力按照规范正确确定储罐的设计压力;
The basic of safety working for high pressure gas stations is scientific design and reasonable installation. 高压气站供气系统安全正常运行的基础是设计科学,安装合理。
Beginning with the development of the civil aviation and the flight safety, this article carrys out the essential meaning of the pressure management among air traffic controllers and summarizes the working pressure, the management methods and the related theories briefly. 论文首先从民航的发展和飞行安全工作出发,提出了压力管理在管制员管理中的重要性,并概述了工作压力、压力管理及其相关理论。
