Rotork has been working with BAE Systems to upgrade a collection of A-range actuators to IQ3 actuators which operate penstocks controlling movement of ships between the ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
เกจวัดแรงดันแก๊สco2 of A-range actuators had reached the end of their operational life after long service in a difficult setting. BAE Systems wanted to retain all the advantages of electrical actuators, so IQ3 actuators were chosen. These had to be specially tailored by Rotork to overcome problems around confined areas and troublesome entry.
IQ3 actuators and IS gearboxes were mechanically tailored so that both actuator and gearbox could be operated by hand without coming into the confined house. Rotork designed particular hand auto levers and thru drive mechanisms for the actuator and gearbox to get rid of the necessity for confined house entry.
Actuators inside the IQ range are watertight, providing ingress protection to IP66/68 at 20 m for 10 days. They have an advanced twin stacked display with configurable knowledge logger performance, and an absolute position sensor provides reliability and accuracy.
