储油罐的变位识别与罐容表标定

Displacement Identification of Oil Storage Tank and Calibration of Tank Capacity Gauge

运用积分思想,建立了油罐体积与油位高度的数学模型。在无变位情况下,根据油罐体积与油位高度的关系式和实际采集的数据结果,在同一坐标系下作出无变位时储油量与油位高度的曲线图,求出储油量与油位高度的函数关系式,建立了罐内储油量与油位高度及变位参数之间的关系模型。确立了油位高度和变位参数之间的关系式,并求出左右球冠和中间圆柱体的储油量。研究结果表明:储油罐罐容表标定并不是一成不变的,应根据实际生活需要收集数据对有关部门制定的罐容表标准进行修正,重新标定罐容表。

The mathematical model of the oil tank's volume and the oil level height are established by integral thought.Based on the real data and relation between the oil tank's volume and the height of oil level,the curve of oil reserves and oil level height without displacement is drawn under the same coordinate system.Then the relational model of the height of oil level and the deflection parameter is established,and the oil reserves about the ball and the cylinder in the middle is determined.The results show that the tank capacity table calibration of the oil tanks is not invariable.The standards for tank capacity table made by some authorities concerned should be amended and rescaled according to our actual need.
