一、序言在检定立罐中发现,首次空罐检定的油罐,在第二次复检时若罐中有油,采用外测检定的方法,容量总比原来的小。究其原因,是由加强圈引起的,本文就加强圈对立罐容量准确度影响加以讨论。立式金属罐容量表一般由主表和静压力修正表组成。主表即空罐时的容量表,静压力修正表是进油后考虑到静压力引起的罐体变形而建立的容量修正表。JJG168-2005《立式金属罐容量》检定规程中给出的静压
First, the preamble found in the test cans, the first test tank empty cans, in the second re-inspection if there is oil tank, the use of external test method, the capacity of the total than the original small. The reason is caused by strengthening the circle, this article will discuss the influence of enhancing the accuracy of the circle opposing tank capacity. Vertical metal tank capacity table is generally composed of the main table and static pressure correction table. The main table is empty when the capacity of the table, static pressure correction table is into the oil after taking into account the static pressure caused by deformation of the tank to create a capacity correction table.
