เพรสเชอร์เกจ has been working with BAE Systems to improve a collection of A-range actuators to IQ3 actuators which operate penstocks controlling motion of ships between the ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A sequence 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 were chosen. These had to be specifically tailored by Rotork to beat problems around confined spaces and troublesome access.
IQ3 actuators and IS gearboxes were mechanically adapted so that both actuator and gearbox could possibly be operated by hand with out getting into the confined space. Rotork designed special hand auto levers and through drive mechanisms for the actuator and gearbox to get rid of the necessity for confined space access.
Actuators within the IQ range are watertight, providing ingress safety to IP66/68 at 20 m for 10 days. They have an advanced dual stacked display with configurable information logger performance, and an absolute place sensor provides reliability and accuracy.
