Abstract

One of the main challenges in oil transmission lines and petroleum products is fluid impurities especially suspended solids. Suspended solid particles, most of which are caused by corrosion of pipe walls and equipment, have many adverse effects on the life and performance of transmission systems. One of the components most affected by solid particles is the pumps. These devices are the beating heart of oil transmission lines. Their performance has a direct impact on the performance of transmission lines. Therefore, the effect of diameter and weight percentage of solid particles on the power consumption of a sample of pumps used in one of the oil transmission lines is investigated. To this end, the pump is simulated numerically in real dimensions and the particle motion in the pump chamber is modeled using an Eulerian–Lagrangian approach. The transferred fluid is liquid gasoline with C₈H₁₈ formula and 761 kg density. The fluid flow is assumed to be incompressible, steady, and turbulent and the effect of the suspended solid particles on the pump power consumption is investigated. The results indicate that the size and amount of particle accumulation can significantly increase the pump power consumption.

摘要

输油管线和石油产品的主要挑战之一是流体杂质，尤其是悬浮固体。悬浮的固体颗粒，其中大部分是由管壁和设备的腐蚀引起的，对传输系统的寿命和性能有许多不利影响。受固体颗粒影响最大的部件之一是泵。这些设备是输油线路的心脏。它们的性能直接影响传输线的性能。因此，研究了固体颗粒的直径和重量百分比对用于其中一条输油管线的泵样品的功耗的影响。为此，泵在实际尺寸上进行了数值模拟，泵室中的粒子运动使用欧拉-拉格朗日方法进行建模。₈ H ₁₈配方和761公斤密度。假设流体流动是不可压缩的、稳定的和湍流的，并研究了悬浮固体颗粒对泵功率消耗的影响。结果表明，颗粒堆积的大小和数量会显着增加泵的功耗。
