Rotork assists BAE Systems in naval base actuator upgrades

Rotork has been working with BAE Systems to upgrade a sequence 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 top of their operational life after long service in a difficult setting. BAE Systems wanted to retain all the benefits of electrical actuators, so IQ3 actuators were chosen. These had to be specially adapted by Rotork to beat issues around confined areas and troublesome entry.
pressure gauge หลักการ ทํา งาน and IS gearboxes were mechanically tailored so that both actuator and gearbox might be operated by hand with out getting into the confined area. Rotork designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to get rid of the need for confined area entry.
Actuators inside the IQ vary are watertight, providing ingress protection to IP66/68 at 20 m for 10 days. They have a sophisticated dual stacked display with configurable data logger performance, and an absolute position sensor supplies reliability and accuracy.
