Rotork assists BAE Systems in naval base actuator upgrades

digital pressure gauge has been working with BAE Systems to upgrade a series 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 end of their operational life after lengthy service in a challenging environment. BAE Systems wished to retain all the advantages of electric actuators, so IQ3 actuators had been chosen. These needed to be specifically adapted by Rotork to overcome problems around confined areas and difficult entry.
IQ3 actuators and IS gearboxes had been mechanically adapted in order that each actuator and gearbox could possibly be operated by hand without getting into the confined area. Rotork designed special hand auto levers and through drive mechanisms for the actuator and gearbox to get rid of the necessity for confined area access.
Actuators within the IQ vary are watertight, providing ingress safety to IP66/68 at 20 m for 10 days. They have a complicated twin stacked show with configurable information logger functionality, and an absolute place sensor supplies reliability and accuracy.
