Rotork assists BAE Systems in naval base actuator upgrades

Rotork has been working with BAE Systems to upgrade a series of A-range actuators to IQ3 actuators which function penstocks controlling movement of ships between the ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A collection of A-range actuators had reached the top of their operational life after lengthy service in a difficult environment. BAE Systems wanted to retain all the benefits of electrical actuators, so IQ3 actuators were chosen. These needed to be specially adapted by Rotork to overcome problems round confined areas and troublesome access.
เกจวัดแก๊ส and IS gearboxes had been mechanically tailored so that each 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 get rid of the necessity for confined space entry.
Actuators within the IQ vary are watertight, offering ingress safety to IP66/68 at 20 m for 10 days. They have a complicated dual stacked display with configurable data logger performance, and an absolute position sensor offers reliability and accuracy.
