Rotork assists BAE Systems in naval base actuator upgrades

Rotork has been working with BAE Systems to upgrade a sequence 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 top of their operational life after long service in a difficult environment. BAE Systems wished to retain all the benefits of electric actuators, so IQ3 actuators had been chosen. These needed to be specifically tailored by Rotork to beat issues round confined spaces and tough entry.
IQ3 actuators and IS gearboxes had been mechanically tailored so that both actuator and gearbox could presumably be manually operated with out getting into the confined area. Rotork designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to remove the need for confined area entry.
Actuators inside the IQ range are watertight, providing ingress safety to IP66/68 at 20 m for 10 days. เพรสเชอร์เกจnuovafima have a sophisticated twin stacked display with configurable data logger performance, and an absolute place sensor supplies reliability and accuracy.
