1500立方米球罐毕业设计论文

随着世界各国综合国力和科学技术水平的提高，球形容器的制造水平也正在高速发展。近年来，我国在石油化工，合成氨，城市燃气的建设中，大型化球形容器得到了广泛应用。

这次设计主要按照GB12337—1998《钢制球形储罐设计》进行设计。本设计共分两部分，第一部分包括球罐的设计；第二部分为外文资料及其对应的中文翻译。其中第一部分介绍了球罐的发展状况和应用场合、材料选择、球罐设计、结构确定、强度计算、绘图等内容。以结构强度的设计计算为主，从基础理论、设计方法、结构分析、标准规定等方面进行了系统的阐述。

本球罐在1.77MPa的设计压力、常温的设计温度下设计，设计厚度为46mm。压力试验采用水压试验，水压试验压力为2.22MPa。球壳材料选Q345R,支柱采用赤道正切式支柱式支承。为了承受风载荷和地震载荷，保证球罐的稳定性，在支柱之间设置拉杆相连，球壳采用的是三带混合式，球壳分块少，板材利用率高，制造工作量小，焊缝短，焊缝个数少，检验量小，施工速度快，使球罐的施工质量易于保证，拉杆结构采用可调节式拉杆，使球罐平衡易于调节。

With the improvement of comprehensive national strength and the world of science and technology level, the manufacturing level of spherical tank is high-speed development. In recent years, China's petrochemical industry, synthetic ammonia, the building of city gas, large-scale spherical tank is widely used.

Designed in accordance with the GB12337-1998 “Design of steel spherical tank”. This design is divided into two parts，the first part includes an overview and design of spherical tank including the calculation of spherical tank; the second part of foreign materials and their corresponding Chinese translation. The first section describes the development of the sphere and applications, material selection, spherical design, structure identification, strength calculation and so on. The most important is the calculation, and I also introduce the structural design, the basic theory, design methods, structural analysis, standards.

The spherical tank in 1.77MPa design pressure, design temperature of room temperature, the design thickness is 46mm. Pressure test using hydraulic pressure test, the hydraulic pressure test with 2.22MPa. Spherical shell material selection Q345R, I use the equator tangent pillar strut-type support. In order to bear wind and seismic loads and ensure the stability of spherical, I set a rod between the pillars, and the three mixed spherical shell is made up with only several parts. The using rate of the plate is small. There are a small number of welds and the length of the welds is small. There is no need to do much test, so it is easy to make. In order to adjust the balance of the tank, that is easy to adjust spherical tank balance.
