Rotork has been working with BAE Systems to upgrade a sequence 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).
A series of A-range actuators had reached the top of their operational life after long service in a difficult surroundings. BAE Systems wanted to retain all the benefits of electric actuators, so IQ3 actuators were chosen. These had to be specifically tailored by Rotork to beat problems around confined areas and troublesome entry.
IQ3 actuators and IS gearboxes had been mechanically tailored so that both actuator and gearbox could probably be operated by hand without entering the confined area. Rotork designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to remove the need for confined space access.
Actuators within the IQ vary are watertight, providing ingress safety to IP66/68 at 20 m for 10 days. เกจวัดแรงดัน10bar have a complicated twin stacked show with configurable knowledge logger functionality, and an absolute place sensor supplies reliability and accuracy.
