ไดอะแฟรม ซีล has been working with BAE Systems to improve a series of A-range actuators to IQ3 actuators which function penstocks controlling movement 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 end of their operational life after lengthy service in a challenging setting. BAE Systems wished to retain all the benefits of electrical actuators, so IQ3 actuators have been chosen. These needed to be specially adapted by Rotork to overcome problems around confined spaces and difficult entry.
IQ3 actuators and IS gearboxes had been mechanically tailored in order that each actuator and gearbox could presumably be operated by hand with out getting into the confined house. Rotork designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to remove the need for confined space entry.
Actuators within the IQ range are watertight, providing ingress safety to IP66/68 at 20 m for 10 days. They have an advanced twin stacked display with configurable data logger performance, and an absolute place sensor offers reliability and accuracy.
