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 motion 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 long service in a challenging surroundings. BAE Systems wanted to retain all the advantages of electrical actuators, so IQ3 actuators had been chosen. These needed to be specially tailored by Rotork to beat issues around confined spaces and tough access.
เกจวัดแรงดันสูง and IS gearboxes had been mechanically adapted so that both actuator and gearbox could possibly be operated by hand with out coming into the confined space. Rotork designed special hand auto levers and through drive mechanisms for the actuator and gearbox to remove the need for confined space access.
Actuators inside the IQ vary are watertight, providing ingress safety to IP66/68 at 20 m for 10 days. They have an advanced dual stacked display with configurable data logger functionality, and an absolute position sensor offers reliability and accuracy.
