一、前言金属球罐,广泛使用在石油、化工和商业等工业部门中,是轻质石油产品及类似该性质的化工产品的重要贮存和计量器具。它具有容量大、占地少、耐压高、密封性好和有效利用率高等优点。随着石油化工及其综合性工业的发展,这种新型计量器必将而且正在起着重要的作用。球罐容积计量的结果,都是根据特定条件下(1个绝对大气压、20℃)的测定数据计算求得的,但是球罐使用却没有固定的条件,温度、压力都是变化的,一般压力为3～13kgf/cm~2。球罐受压后,容积必然要发生变化,若不考虑这种影响,将会给计量结果带来较大误差。为搞好经济核算、节能工作和出口贸易,本文讨论了在一定温度条件下,压力对金
I. Introduction Metal domes, widely used in the petroleum, chemical and commercial industries, are important storage and measuring instruments for light petroleum products and chemical products of this nature. It has the advantages of large capacity, small footprint, high pressure, good sealing and effective utilization. With the development of petrochemical industry and its comprehensive industry, this new type of measuring machine will and will play an important role. The results of measuring the volume of the spherical tank are calculated based on the measured data under certain conditions (1 atm, 20 ° C). However, there are no fixed conditions for the use of the spherical tank, and the temperature and the pressure vary. The general pressure 3 ~ 13kgf / cm ~ 2. After the pressure tank, the volume will inevitably have to change, if you do not consider this effect, will give measurement results greater error. In order to do a good job in economic accounting, energy conservation and export trade, this article discusses the pressure on gold
