Rotork has been working with BAE Systems to upgrade a series of A-range actuators to IQ3 actuators which function penstocks controlling movement of ships between the ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
เกจวัดแรงดันแบบแห้ง of A-range actuators had reached the top of their operational life after long service in a difficult environment. BAE Systems needed to retain all the benefits of electrical actuators, so IQ3 actuators were chosen. These needed to be specifically tailored by Rotork to overcome problems round confined areas and difficult access.
IQ3 actuators and IS gearboxes have been mechanically adapted so that each actuator and gearbox might be manually operated with out getting into the confined area. Rotork designed particular hand auto levers and thru drive mechanisms for the actuator and gearbox to remove the need for confined house access.
Actuators inside the IQ vary are watertight, offering ingress safety to IP66/68 at 20 m for 10 days. They have an advanced twin stacked show with configurable knowledge logger functionality, and an absolute place sensor supplies reliability and accuracy.
