管道压降可持续测量系统研究
|
摘要
为解决传统引压压降测量装置在测量原油管道压降过程中普遍存在的测量结果误差大、测量易中断的问题,设计了一种管道压降可持续测量系统。在传统引压压降测量装置的基础上引入驱替疏通单元和自动控制单元,当测量的压差值大于预设阈值时启动驱替疏通单元,对引压孔进行疏通。通过与传统引压压降测量装置的实验对比,发现改进后的压降可持续测量系统能够较好地完成原油管道压降的测量工作。
In order to solve the problem that the measurement error of the traditional measuring device in measuring the pressure drop of crude oil pipeline is big and the measurement is easy to be interrupted, a sustainable pressure drop measurement system suitable for the crude oil pipeline was designed. The system introduced an automatic control unit and a displacement dredge unit on the basis of a conventional pressure drop measuring device. When the measured pressure drop is greater than a preset threshold, the displacement unit is activated to dredge the clogged pressure hole. Compared with the traditional pressure drop measuring device, the improved pressure drop sustainable measurement system can better complete the pressure drop measurement work of crude oil pipelines.
