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 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 end of their operational life after lengthy service in a difficult surroundings. BAE Systems needed to retain all the benefits of electrical actuators, so IQ3 actuators had been chosen. These had to be specially adapted by Rotork to beat problems around confined spaces and troublesome entry.
เกจอาร์กอน and IS gearboxes have been mechanically adapted in order that each actuator and gearbox could be operated by hand with out entering the confined space. Rotork designed special hand auto levers and through drive mechanisms for the actuator and gearbox to get rid of the need for confined area access.
Actuators inside the IQ vary are watertight, offering ingress protection to IP66/68 at 20 m for 10 days. They have an advanced dual stacked display with configurable knowledge logger performance, and an absolute place sensor supplies reliability and accuracy.
