【摘要】：控制阀作为流体过程控制最重要的元器件之一,它的安全运行,健康状况直接决定了现场应用装置的可靠性。随着智能仪表的发展,各种现场总线技术的应用,在国内,采用HART、FF等协议的定位器的普及,使得智能在线阀门诊断技术的大规模普及得以成为可能。在线诊断具有不干扰现场运行,自动生成阀门体检报告等特点,正在越来越多的现场使用。本文主要探讨了利用智能数字定位器以及大数据分析的数字技术,开展"阀门在线巡检,精准维修",在分析业界阀门诊断的各种方式基础上,结合阀门的检维修,并以GE最新推出的基于云计算平台Predix的系统Valve Aware为例,详细介绍了这一在线诊断的原理和前景。利用这一技术,可以做出准确的预防性诊断,为阀门保养维修提供针对性的方案,从而减少工厂应用装置的停机时间,降低维修成本,为工厂带来极大的效益。
[Abstract]:Control valve as one of the most important components of fluid process control, its safe operation and health condition directly determine the reliability of the field application device. With the development of intelligent instruments and the application of various fieldbus technologies, the popularization of locators using HART,FF and other protocols in China makes the large-scale popularization of intelligent on-line valve diagnosis technology possible. On-line diagnosis has the characteristics of no interference with field operation, automatic generation of valve physical examination report and so on, and is being used more and more in the field. This paper mainly discusses the use of intelligent digital locator and the digital technology analyzed by big data to carry out "On-line Inspection and accurate maintenance of Valves". On the basis of analyzing various ways of valve diagnosis in the industry, combined with valve inspection and maintenance, The principle and prospect of this online diagnosis are introduced in detail by taking Valve Aware, a system based on cloud computing platform Predix, which is newly launched by GE, as an example. By using this technology, accurate preventive diagnosis can be made, and a targeted scheme for valve maintenance and repair can be provided, thus reducing the downtime of the plant application device, reducing the maintenance cost, and bringing great benefits to the factory.
