1.测量依据及方法依据JJG168-2005《立式金属罐容量》检定规程,立式金属罐(以下称立罐)容量检定方法,采用几何测量法,通常被检测的立罐视为圆筒体,测量罐体的基本直径、各圈板的径向偏差、圈板高度、厚度等几何参数,同时考虑到罐体的椭圆度大小、倾斜幅度、液体静压力对罐壁膨胀影响和罐底的形状,按规程规定的计算公式和计算程序,编制出立罐在空罐状态下不同高度与容量对应表、区间容量表,以及静压力修正表,作为立罐容量计量的依据。2.数字模型
1. Measurement basis and method According to JJG168-2005 “vertical metal tank capacity” verification procedures, vertical metal tank (hereinafter referred to as the tank) capacity verification method, the use of geometric measurement method, the tank is usually detected as a cylinder , Measuring the basic diameter of the tank, the radial deviation of each ring plate, ring plate height, thickness and other geometric parameters, taking into account the size of the tank ellipticity, tilt amplitude, liquid static pressure on the tank wall expansion and tank bottom Shape, according to the rules of the calculation formula and calculation procedures, the preparation of cans in the empty tank state of different height and capacity of the corresponding table, the section capacity table, as well as static pressure correction table, as a basis for the measurement of tank capacity.
