Inefficient actuators upgraded to Rotork intelligent electric actuation at a water adventure site
Rotork的IQ3执行器在英国英格兰东北部的一个白水中心改进并现代化了流量控制系统。
Tees Barrage International White Water Center是一个活动和体育网站。访客可以进行漂流，划独木舟，皮划艇，动力划船和划桨板。它是位于Tees河Tees上的Tees Barrage Park游客景点的一部分。
Opened in 1995, the Tees Barrage was built to provide for the development and improvement of the area and recreational use of the River Tees by maintaining an upstream river level. It is looked after by Canal & River Trust who are undertaking a project to help to improve the performance of the existing control system.
现场的penstocks用河水为水路喂食，防止海水进入涨潮时进入公园（海水对白水用户不可取，将导致设备腐蚀）并保持水位进入公园，以防止其在极端的洪水中泛滥天气状况。旧的控制系统是液压操作的，并且证明是不可靠的。它是由线性液压缸和一个没有扭矩保护的单个液压电源包提供的，没有数据或条件监控和有限的位置反馈。这会导致骨折断裂，机油泄漏和需要计划外的维护干预。现有的电源电缆无法提供五个执行器的能力，需要更新以遵守最新法规。
The customer chose to upgrade to IQ3 actuators, Rotork’s flagship intelligent electric actuator. IQ3 actuators have high degrees of environmental protection and water ingress protection. They have a double-sealed enclosure (IP66/68) and are therefore ideally suited for water applications. The customer was impressed with many benefits IQ3 actuators bring, including: the ability to capture historical performance data through the integrated data logger, accurate position and torque sensing, and integral controls. IQ3 actuators have a low total cost of life and their high degrees of reliability/availability means a reduced likelihood of any interruption to operation.
旋转式提供的替换系统包括机械界面和电气控制系统。具有Modbus TCP的IQ3执行器（通过三菱PLC）和防破坏性盖盖，旋转式IB变速箱，电气/控制电缆，基座，替换电气分配开关和以太网开关均提供给该地点。其中一个penstocks及其执行器很难访问，因此旋转站点服务为操作员提供了一个旋转式远程手动站，以控制执行器，同时站立可达100米，并可以访问重复的屏幕。
The IQ3 actuators with IB gearboxes (increasing torque to a maximum of 7,604 Nm) now operate penstocks to control the level within the Tees Barrage International White Water Centre (TBIWWC), as well as ensuring that public facilities and areas are not flooded during tidal movements. The penstocks are also an isolation point to enable maintenance to take place within the white water centre. The wide range of products and services was secured by the expertise shown by Rotork engineers after assessing the site which led to an increase in the service offered, including the cabling (inspection, testing, removal and installation), penstock repairs, and design/manufacture/installation of mechanical adaptions. Scaffolding, security and on-site project management were provided by AmcoGiffen.
