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 movement 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 tip of their operational life after long service in a difficult environment. เครื่องมือที่ใช้วัดความดัน wished to retain all the benefits of electric actuators, so IQ3 actuators have been chosen. These had to be specially adapted by Rotork to overcome issues round confined areas and difficult access.
IQ3 actuators and IS gearboxes have been mechanically adapted so that each actuator and gearbox could possibly be manually operated with out getting into the confined space. Rotork designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to remove the need for confined space access.
Actuators throughout the IQ vary are watertight, offering ingress protection to IP66/68 at 20 m for 10 days. They have a sophisticated dual stacked display with configurable data logger functionality, and an absolute place sensor offers reliability and accuracy.
