Rotork has been working with BAE Systems to improve a collection of A-range actuators to IQ3 actuators which operate penstocks controlling motion of ships between the sea and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
เพรสเชอร์เกจคือ of A-range actuators had reached the end of their operational life after long service in a difficult environment. BAE Systems needed to retain all the benefits of electrical actuators, so IQ3 actuators had been chosen. These needed to be specifically adapted by Rotork to overcome issues around confined areas and difficult entry.
IQ3 actuators and IS gearboxes were mechanically adapted in order that both actuator and gearbox might be manually operated with out entering the confined area. Rotork designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to remove the necessity for confined area access.
Actuators throughout the IQ range are watertight, offering ingress protection to IP66/68 at 20 m for 10 days. They have an advanced twin stacked display with configurable information logger performance, and an absolute place sensor offers reliability and accuracy.
