加油站的地下储油罐在使用一段时间后,由于地基变形等原因使罐体的位置会发生纵向倾斜和横向偏转等变化,从而导致罐容表发生改变,这种变位形成的计量误差是目前石油、化工、轻工等企业急需解决的问题,本文给出了油罐变位后纵向倾斜角度、横向偏转角度、液面高度和罐内油量容积之间的一般函数关系式。实际操作中可根据函数计算值对罐容表进行重新标定,从而解决储油罐因变位引起的计量误差问题,减少实际测量中的工作量。 Gas tank underground storage tanks in use for some time, due to deformation of the foundation so tank position will occur vertical tilt and lateral deflection and other changes, resulting in tank capacity table changes, this displacement measurement error is formed At present, petroleum, chemical industry, light industry and other enterprises urgently need to be solved. This paper gives the general functional relationship between longitudinal tilting angle, lateral deflection angle, liquid level and tank oil volume after tank displacement. In practice, the tank capacity table can be recalibrated according to the calculated values ​​of the function to solve the measurement error problem caused by the displacement of the oil tank and reduce the workload in the actual measurement.
