介绍了一种流体管道流动观测装置,该装置利用场作用力以非接触方式驱动流体在环形管内循环流动,在整个观测过程中流体始终离不开测试管道,所以不改变流体的管道流动历史,实现了在有限长度的试验管道内任意长时间、长距离地模拟及观测实际输油管道的流动,从而满足有记忆流体管流实验的需要,尤其是对于象含蜡原油这样的非牛顿流体的管道流动实验,本装置提供了一种新的试验测量手段。装置测粘范围为40～6000 mPa·s,试验样品用量约550mL,温度控制精确度高,具有无级变速功能,观测过程中基本无轻组分损失。
A device for observing the flow of a fluid pipeline is introduced. The device uses the force of a field to drive the fluid to circulate in a circular tube in a non-contact manner. During the whole observation process, the fluid can not be separated from the test tube. Therefore, the flow history of the fluid is not changed, Realizing the simulation and observation of actual oil pipeline flow for any long and long distance in a limited length of test pipeline to meet the requirement of pipe flow test with memory fluid, especially for non-Newtonian fluid such as waxy crude oil Flow experiment, the device provides a new means of experimental measurement. The range of viscosity of the device is 40 ~ 6000 mPa · s, the amount of test sample is about 550mL, the temperature control accuracy is high, and the device has the function of continuously variable speed. There is almost no light component loss during the observation.
