Rotork assists BAE Systems in naval base actuator upgrades

Rotork has been working with BAE Systems to upgrade a collection of A-range actuators to IQ3 actuators which operate penstocks controlling movement of ships between the sea and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
เกจแรงดัน of A-range actuators had reached the tip of their operational life after long service in a difficult environment. BAE Systems wanted to retain all the advantages of electrical actuators, so IQ3 actuators had been chosen. These needed to be specially adapted by Rotork to beat issues round confined areas and difficult entry.
IQ3 actuators and IS gearboxes had been mechanically tailored in order that both actuator and gearbox might be operated by hand without getting into the confined space. Rotork designed special hand auto levers and through drive mechanisms for the actuator and gearbox to eliminate the need for confined space access.
Actuators throughout the IQ range are watertight, offering ingress safety to IP66/68 at 20 m for 10 days. They have an advanced dual stacked display with configurable data logger functionality, and an absolute position sensor offers reliability and accuracy.
