Rotork assists BAE Systems in naval base actuator upgrades

Rotork has been working with BAE Systems to improve 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 tip of their operational life after long service in a challenging setting. BAE Systems wanted to retain all the advantages of electrical actuators, so IQ3 actuators had been chosen. These had to be specially tailored by Rotork to overcome problems around confined spaces and difficult entry.
IQ3 actuators and IS gearboxes had been mechanically adapted in order that each actuator and gearbox could be manually operated with out getting into the confined house. ส่วนประกอบpressuregauge designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to eliminate the need for confined area access.
Actuators inside the IQ range are watertight, providing ingress safety to IP66/68 at 20 m for 10 days. They have an advanced twin stacked show with configurable data logger functionality, and an absolute position sensor supplies reliability and accuracy.
