Rotork assists BAE Systems in naval base actuator upgrades

Rotork has been working with BAE Systems to improve 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).
A series of A-range actuators had reached the tip of their operational life after long service in a difficult environment. BAE Systems needed to retain all the benefits of electric actuators, so IQ3 actuators have been chosen. These had to be specifically tailored by Rotork to beat problems round confined spaces and tough entry.
pressure gauge ยี่ห้อ tk and IS gearboxes have been mechanically adapted in order that both actuator and gearbox could probably be manually operated without coming into the confined house. Rotork designed particular hand auto levers and thru drive mechanisms for the actuator and gearbox to get rid of the necessity for confined space access.
Actuators throughout the IQ vary are watertight, providing ingress safety to IP66/68 at 20 m for 10 days. They have a sophisticated twin stacked display with configurable knowledge logger functionality, and an absolute position sensor supplies reliability and accuracy.
