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 function penstocks controlling motion of ships between the sea and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A collection of A-range actuators had reached the tip of their operational life after lengthy service in a difficult surroundings. BAE Systems wanted to retain all the advantages of electric actuators, so IQ3 actuators have been chosen. These had to be specifically adapted by Rotork to overcome problems round confined spaces and troublesome access.
IQ3 actuators and IS gearboxes have been mechanically tailored in order that both actuator and gearbox could probably be manually operated with out entering the confined area. Rotork designed special hand auto levers and through drive mechanisms for the actuator and gearbox to get rid of the need for confined space access.
Actuators within the IQ vary are watertight, offering ingress protection to IP66/68 at 20 m for 10 days. เกจวัดแรงดันลมดิจิตอล have a complicated dual stacked show with configurable information logger performance, and an absolute position sensor offers reliability and accuracy.
