Rotork assists BAE Systems in naval base actuator upgrades

Rotork has been working with BAE Systems to improve a sequence 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 series of A-range actuators had reached the top of their operational life after lengthy service in a difficult surroundings. BAE Systems wished to retain all the advantages of electrical actuators, so IQ3 actuators have been chosen. These had to be specially tailored by Rotork to overcome problems around confined spaces and difficult access.
IQ3 actuators and IS gearboxes were mechanically adapted in order that both actuator and gearbox could presumably be operated by hand without coming into 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 area entry.
Actuators within the IQ vary are watertight, providing ingress protection to IP66/68 at 20 m for 10 days. เกจวัดแรงดัน have a complicated twin stacked display with configurable data logger functionality, and an absolute position sensor provides reliability and accuracy.
