流控制，向后兼容和过时管理
流控制不是一项新技术。它是数千年前在记录的历史上首次出现的：考虑罗马渡槽，古老的灌溉系统和水厂。阀门技术在工业革命期间进化，并继续这样做，从而导致了含义流量控制并在必要时改进的进步。如今，在控制液体和气体流动的各种行业和应用中都发现了流量控制。执行器是流量控制中的设备的关键项目，已将自动化带入原本手动过程。在石油和天然气，水，电力，工艺和行业的大量应用中发现了它们。流量控制继续进行创新，使操作员可以访问最新技术，即使在已经运行了多年的网站上。
Actuators can be electrically, pneumatically, hydraulically or electro-hydraulically powered. The choice of which actuator to use depends on multiple factors, such as location, available power supply, valve type/size, type of fluid being controlled etc. For example, pneumatic actuators have traditionally been used in applications such as oil and gas, offering critical high-speed fail-safe or emergency shutdown (ESD) duties in extreme or hazardous locations. Some electric actuators are referred to as specialist process control actuators because they provide continuous, modulating control. With a focus on consistency and reliability, they are ideally suited for combustion, food and beverage, water and power applications. Intelligent electric actuators are found in a wide range of applications because of their reliability and efficiency, as well as ease of access to a power supply. Within oil and gas applications they are favoured because they do not release emissions (as can be the case with pneumatic actuators powered by the produced gas). They are increasingly the actuator of choice for site operators who wish to increase asset uptime because of their ability to capture historical performance data.
可以在执行器制造商的支持下对所有类型的执行器的专业管理，以防止由于过时的关注而导致现场停机。现场运营商知道与老化资产相关的风险。潜在资产过时的主要危险是对性能和正常运行时间的影响。如果资产无法有效地运行或全面运行，那么对生产和利润的影响可能很严重。资产损失或不良资产导致的计划外停机时间可能导致性能差，产品质量差和产量降低，这反过来又可能导致声誉损失和收入损失。
Technological advances now allows for specific obsolescence concerns to be met with upgrade processes. For example, Rotork’s A-range actuator was launched in the 1960s and can still be found operating many decades later. They are known as ‘SyncroSET’ actuators, with an external reversing contactor starter and local controls. A feature available within the IQ range of intelligent electric actuators, IQ3 SET, means that two situations that appear to be opposed (IQ3 technology with the set-up of an A-range actuator), is possible. The recent launch of Rotork’s IQ3 SET allows for backwards compatibility to the 1960s (including A-range), updating to the latest actuation technology without affecting existing plant infrastructure. It allows not only for immediate improved performance, but future-proofs the site for the years to come. As such, it can be considered as a key part of a site’s obsolescence management, replacing legacy actuators with the latest intelligent actuator platform. Use of IQ3 SET ensures budget predictability, improved performance and reduced downtime. Holistic consideration of the whole life cycle of an asset ensures diminished risk of failure and increases the ability to continue operation: it future-proofs the system, with seamless integration into existing plant architecture and no need to change existing cables or control systems. The very latest in flow control technology is now more accessible to customers than ever.
流量控制技术在我们所有人都依赖的行业（例如水，电力和制造业）中起着至关重要的作用。过时关注的管理是有效的资产管理策略的重要组成部分，可确保可靠性提高和继续运行。允许向后兼容旧产品的技术是支持现场所有资产持续高性能的必不可少的工具。
