立式罐的容量通常是在空罐状态下计量的,当其内装有液体时,由于液体的静压力作用,罐体必然发生弹性形变,使罐的容量增大,该增大值称为液体静压力效应修正值,这在当今大容量计量中是必须考虑的重要问题之一。一、静压力效应修正值的计算立式罐是金属制的圆筒体。为了计算它的液体静压力修正值,首先需考究罐壁受液体静压力作用而引起的径向位移;然后,相应的修正值即可通过径向位移积分求得。
Vertical tank capacity is usually measured in the empty tank state, when it is filled with liquid, due to the static pressure of the liquid, the tank will inevitably undergo elastic deformation, so that the capacity of the tank, the increase is called the liquid Static pressure effect correction, which is one of the important issues that must be considered in today’s high volume metering. First, the static pressure effect correction value calculation Vertical tank is made of metal cylinder. In order to calculate its hydrostatic pressure correction value, the radial displacement caused by the hydrostatic pressure of the tank wall must first be considered. Then, the corresponding correction value can be obtained by integrating the radial displacement.
