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 motion of ships between the sea 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 long service in a difficult surroundings. BAE Systems wanted to retain all the advantages of electrical actuators, so IQ3 actuators have been chosen. These needed to be specifically tailored by Rotork to beat issues around confined spaces and difficult access.
IQ3 actuators and IS gearboxes were mechanically adapted so that both actuator and gearbox might be manually operated without getting into the confined area. เกจไนโตรเจนsumo designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to eliminate the necessity for confined area entry.
Actuators within the IQ range are watertight, offering ingress safety to IP66/68 at 20 m for 10 days. They have a sophisticated twin stacked display with configurable information logger functionality, and an absolute position sensor provides reliability and accuracy.
