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 ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A collection of A-range actuators had reached the end of their operational life after lengthy service in a difficult environment. เกจวัดแรงดันแก๊สอาร์กอน wanted to retain all the advantages of electric actuators, so IQ3 actuators have been chosen. These needed to be specifically adapted by Rotork to overcome problems around confined spaces and difficult access.
IQ3 actuators and IS gearboxes were mechanically adapted in order that both actuator and gearbox might be operated by hand with out coming into the confined house. Rotork designed special hand auto levers and through drive mechanisms for the actuator and gearbox to eliminate the need for confined area access.
Actuators within the IQ range are watertight, providing ingress safety to IP66/68 at 20 m for 10 days. They have a sophisticated dual stacked display with configurable knowledge logger performance, and an absolute position sensor provides reliability and accuracy.
