Rotork现场服务有助于提高泰晤士水的效率
Thames Water is the UK’s largest water company, providing essential services for 15 million customers in London and the Thames Valley. The company invests heavily in new technologies and improvements to increase efficiency and meet the challenges imposed by strict environmental regulations. A framework agreement for the supply of Rotork valve actuators contributes to the achievement of these objectives through the upgrading and automation of flow control equipment in many areas of Thames Water’s operations.
Rotork还通过阀门和驱动厂升级，帮助泰晤士水进行了设计和安装。如两个最近的例子所示，这些合同通常包括Rotork现场服务可以提供的扩展范围工程学科，导致简化的合同路线和对额外子承包商的要求减少。这两个例子都涉及安装Rotork最新的IQ3非侵入式智能阀门执行器，包括复杂的诊断技术，以提高效率，降低维护和改善的长期资产管理。
第一个网站是一个河流起飞进口原料water pumping station, where IQ3M modulating actuators have been installed to replace locally operated electric motors on three large river gates. The upgrade enables the gates to accurately maintain a steady flow into the pumping station under all ambient conditions by automatically responding to changes to the condition of the river. The old motors were controlled from a switch panel inside an adjacent kiosk, but the unpredictable requirement for operation at any time, day and night, could cause operating delays which, combined with the restricted ability to accurately position the gates, resulted in potentially problematic fluctuations in the water supply to the pumping station.
IQ3M执行器现在从超声波电平传感器和PLC自动操作，从而实现精确，响应，几乎无限的栅极运动，每天24小时，没有任何人为干预。在网站的中央控制室中监控安装，如果需要，致动器也可以远程操作。
除了提供和安装三个ROTARK IQ3M执行器和多圈齿轮箱外，ROTARK现场服务的工作还涉及河流和齿轮箱之间的新适应设计和制造，拆除旧电机和布线，在执行器和售货亭之间安装电隔离器和新电源和控制布线，在售货亭中修改配电板和不间断电源。在允许的时间内完成执行器的机械和电气安装和调试，而不会中断治疗工程的正常操作。
At the second site, at another major water treatment works, Rotork has automated large manually operated penstocks on the inlet to a reservoir. Rotork Site Services performed a complete mechanical and electrical upgrade on one 60 inch and four 54 inch penstocks, involving the removal of old gearboxes and pedestals, the design and installation of new pedestals and installation of IQ3 actuators and bevel gearboxes. The electrical work encompassed new isolators and floodlights, cabling between the actuators and an existing kiosk and modifications to an existing distribution board.
In both cases, the replacement of old equipment with Rotork actuators has improved the efficiency of what had been laborious and time consuming processes. David West, Thames Water’s West London Abstraction Engineer, comments:
“在第一个站点，新的入口门执行器和相关的自动化控制系统将允许我们以比以前可以的水平更高的入口通道。这将通过增加我们所有的原水泵上的吸头来节省大量的泵送能源成本。
在第二个站点，执行器和网站照明的安装使得该法定储存器的隔离更快，更安全。最近是一个非常有物有的四个男人工作了几个小时的工作现在是由Rotork执行器进行的。“
