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 ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
เกจวัดแรงดันน้ำ10บาร์ of A-range actuators had reached the end of their operational life after lengthy service in a difficult surroundings. BAE Systems needed to retain all the advantages of electric actuators, so IQ3 actuators have been chosen. These had to be specially adapted by Rotork to overcome problems round confined spaces and difficult access.
IQ3 actuators and IS gearboxes had been mechanically tailored in order that both actuator and gearbox could be operated by hand without getting into the confined house. 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 protection to IP66/68 at 20 m for 10 days. They have a sophisticated twin stacked show with configurable information logger functionality, and an absolute position sensor offers reliability and accuracy.
