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 ocean 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 needed to retain all the advantages of electric actuators, so IQ3 actuators had been chosen. These had to be specifically adapted by Rotork to overcome issues around confined areas and troublesome access.
เกจวัดแรงดัน and IS gearboxes had been mechanically adapted so that each actuator and gearbox could 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 remove the necessity for confined area entry.
Actuators throughout the IQ range are watertight, providing ingress protection to IP66/68 at 20 m for 10 days. They have an advanced twin stacked show with configurable information logger functionality, and an absolute place sensor supplies reliability and accuracy.
