燃油终端升级安装高级气门致动和控制

沃帕克（VopakPakscan™。执行器通过旋转式管理主站and the customer benefits from the many features these products provide.

独立的储罐提供商Vopak正在南非的Vopak终端Durban提高和增强燃油容量，这是一个重要的地点，活动涵盖了石油产品的进出口，出口和分布。

该计划旨在扩大和增强Vopak的基础设施，以满足南非对这些产品的不断增长的需求，提高燃料供应的安全性并促进进口清洁燃料的进口。The project will increase the site’s storage capacity from 177,735 to 234,200 cubic metres (cbm) by replacing a number of existing tanks with new state-of-the-art storage tanks and installing new ancillary infrastructure including pipelines, pump bays and fire-fighting equipment. Undertaken in several stages, the programme also involves upgrades on existing tanks to achieve the highest safety standards and the replacement of manual equipment with automatic technology.

Much of this work is being carried out by Engineering Process Control (EPC), Rotork’s long-standing local agent in Kwazulu-Natal. In 2012, with assistance from Rotork’s South Africa facility, EPC began equipment specification discussions with Fluor, the Engineering Procurement and Construction Management (EPCM) consultant, regarding the planned upgrade projects.

其中的第一个是一个坦克过度填充保护项目，涉及现有的坦克入口和出口阀的自动化，该项目于2014年完成。在这里，有63个最新的Rotork Iq智能电动多转弯执行器安装在门阀和9个最新的Rotork IQT智能零件转向执行器安装在三重偏移蝴蝶和球阀上。EPC执行的工作包括设计和制造新的阀门顶级工作适应和执行器的调试。

These actuators are monitored and controlled by a single RotorkPakscan主站和2线数字网络，提供打开/关闭阀门控制和远程位置反馈，链接到横正在分布式控制系统（DCS）。专为阀致动环境设计Pakscan将安全的现场通信与内置网络冗余结合在一起，即使在设备或电缆故障的情况下，也可以保持控制。分别有线紧急关闭（ESD）控制连接到坦克的高级别开关和警报。

坦克过填充保护项目还包括在现场排水系统上自动化现有的蝴蝶阀。这些阀配备了旋转智商执行器和四分之一的IW蠕虫变速箱，该计划旨在消除外部无意中排出外部环境中船舶内溢出的风险。

下一次升级（称为燃料2项目）始于2014年。这项工作涉及拆除一些旧的小型化学储罐，并用较大的柴油和无铅汽油储罐替换。这些坦克与最近建造的Transnet新型多产品管道连接，该产品从德班到约翰内斯堡运行，以满足对进口精制石油产品的新兴需求。与管道的连接由大型新歧管和泵舱提供。

与油箱过填充保护项目一样，燃油2项目的所有关键区域中的阀门都是用旋转式执行器自动化的，并由Pakscan2线网络链接到横川DCS。30旋转摩托车的电湿型电动型故障安全执行器在坦克的入口和出口阀上操作三重偏移蝴蝶阀。这些执行器配备了硬线ESD电路，将覆盖Pakscancontrol and close the valves in the event of an emergency. Flow control on the new manifold and pump bay is provided by 33 IQ actuated double block and bleed plug valves, whilst an additional two electro-hydraulic actuators operate ball valve on the pipeline pig launcher.

四个Pakscan热门主站控制两个升级项目上的四个单独的循环网络。在该领域，总共安装了164个Pakbox，以将单个执行器隔离到主电源和Pakscan在需要维护的局部关闭期间的网络。在这些事件中，pakboxs保持了Pakscannetwork for the operation of the other field units on the same loop.

在燃油2项目的最后部分，EPC在三重偏移蝴蝶阀上安装了14个旋转CP紧凑型气动执行器，以进行泊位应用。EPC拥有自己的工程和安装（E＆I）部门，该部门实现了Fuel 2项目的施工范围，促进了良好的通信并成功地调试了所有Rotork设备。

2015年，EPC开始与Royal Vopak的新EPCM顾问Kanty＆Templar合作，在燃油3项目中，涉及部分拆除两个植物区域，为重建专用的道路装载设施提供空间，并为无铅汽油和柴油提供额外的存储空间。EPC再次提供，安装和调试了所有旋转设备，其E＆I部门已经完成了部分建筑。

The upgrades at the Vopak Terminal Durban utilise Rotork electric valve actuation technologies for automated flow control and vital safety related duties associated with the import, export and storage of a varied range of liquid bulk products. The actuators incorporate ATEX explosionproof certification and IP68 double-sealed watertight enclosures designed for harsh and exposed environments. They are monitored and controlled on fully redundant RotorkPakscandigital bus loops, linked to the plant’s DCS byPakscan主站。除了提供可靠的常规流量控制的智商和智商智能执行器外，冰胶的独立电溶剂混合执行器还战略性地安装在坦克入口和出口阀上，以提供潜在的溢出的故障安全保护，并在隔离单个储罐的情况下，潜在的紧急情况。

The specialised design of the Skilmatic actuator has proved that the performance required to achieve the swift fail-safe operation demanded by ESD duty can be successfully delivered through the electro-hydraulic route.

Skilmatic actuators use a simple, very reliable mechanical spring to provide fail-safe valve movement, whilst precise and quick valve movement in the opposite direction is achieved hydraulically by means of an integral electrically powered pump. With this design, reliable fail-safe performance can be combined with the benefits of Rotork IQ intelligent electric actuation technologies, facilitating a high level of asset management encompassing accurate control, monitoring and alarm signalling, operational data logging and diagnostics. Savings in capital and maintenance costs can also be achieved by the simplification of the overall plant control system facilitated by an all-electric solution.

All the actuators share Rotork’s IQ non-intrusive setting, commissioning and data communication technologies. A handheld, intrinsically safe, Rotork Bluetooth setting tool enables swift and secure commissioning by means of easy to follow ‘point and shoot’ menus. The same setting tool also enables actuator configuration and data logger files to be transferred from the field to the office for diagnostics, analysis and storage. IQ intelligent actuator technology is capable of providing a proliferation of data, recording activity including the number of valve operations, alarms, valve torque profiles, unauthorised operation attempts and many other events. In combination with Rotork IQ-Insight 2 software, this data can help to maximise plant utilisation by identifying potential problems and facilitating efficient asset management.

将智商技术融合到冰刀执行器中，引入了相同的高水平控制和监测功能。可以访问和调整设置，例如位置限制，控制选项，警报和指示功能。与智商一样，执行器状态，控制和警报图标都可以在照明显示器上查看，该显示还提供了对包括诊断和帮助屏幕在内的实时信息的访问。

冰滑控制模块使得满足要求运算符的要求，包括与Pakscandigital network control system. Certified to the requirements of IEC61508-2:2010 for use in safety systems performing safety functions up to SIL2 and SIL3, Skilmatic actuators are also capable of partial stroke testing (PST), enabling valves to be tested without interrupting the routine process.

这对于在测试安全临界阀时最大程度地减少过程关闭非常重要。测试执行器中的所有关键组件，包括液压和运动，以确认停机需求的可用性。可以使用设置工具远程或本地启动测试。测量了针对中风时间的部分中风位置，并将其与在调试阶段记录的中风时间的原始位置进行了比较。显示通行证或失败，如果启用，将激活故障警报。警报是可以将特定于客户的警报和状态要求或通用组警报配置为三个。还提供了监视继电器以监视电源和任何硬件错误。

溜冰力执行器配备了整体电路，旨在接收单独连接的离散ESD警报信号，即使发生电力故障，也将覆盖任何其他输入并将执行器移至预定的安全位置。可以将ESD信号配置为通过硬接线电路来控制内部处理器的关闭电路。该处理器电路监视位置和内部液压压力，并提供警报监控，但ESD电路是独立的，从而优先考虑ESD命令。在ESD方案中，执行器将立即返回预定的安全位置，并准备在恢复ESD信号时在下一个命令上操作。作为额外的保障，可以启用可选的ESD手册重置，以限制执行器操作直到在执行器或外部安装开关的本地重置。可以调整关闭速度以满足应用程序的特定要求。
