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 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 sequence of A-range actuators had reached the end of their operational life after lengthy service in a challenging surroundings. BAE Systems needed to retain all the benefits of electric actuators, so IQ3 actuators were chosen. These had to be specifically adapted by Rotork to overcome issues round confined spaces and troublesome access.
IQ3 actuators and IS gearboxes had been mechanically tailored in order that each actuator and gearbox could be manually operated with out coming into the confined house. 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 inside the IQ vary are watertight, providing ingress protection to IP66/68 at 20 m for 10 days. เครื่องมือวัดpressure have a complicated dual stacked display with configurable information logger performance, and an absolute place sensor provides reliability and accuracy.
