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 operate penstocks controlling movement of ships between the ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A sequence of A-range actuators had reached the tip of their operational life after lengthy service in a challenging environment. BAE Systems wanted to retain all the advantages of electrical actuators, so IQ3 actuators were chosen. These had to be specially tailored by Rotork to beat problems around confined areas and difficult entry.
IQ3 actuators and IS gearboxes have been mechanically adapted so that each actuator and gearbox might be operated by hand without entering the confined space. Rotork designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to get rid of the need for confined area entry.
Actuators inside the IQ vary are watertight, offering ingress protection to IP66/68 at 20 m for 10 days. เพรสเชอร์เกจน้ำ have a complicated twin stacked display with configurable information logger functionality, and an absolute place sensor provides reliability and accuracy.
