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).
เพรสเชอร์เกจไฮดรอลิค of A-range actuators had reached the end of their operational life after lengthy service in a difficult environment. BAE Systems wished to retain all the advantages of electrical actuators, so IQ3 actuators had been chosen. These had to be specially adapted by Rotork to beat problems around confined spaces and difficult access.
IQ3 actuators and IS gearboxes had been mechanically tailored so that both actuator and gearbox might be manually operated with out entering the confined space. Rotork designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to get rid of the need for confined area 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 data logger functionality, and an absolute position sensor supplies reliability and accuracy.
