Rotork 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 sequence of A-range actuators had reached the tip of their operational life after lengthy service in a difficult environment. BAE Systems wished to retain all the benefits of electrical actuators, so IQ3 actuators had been chosen. These had to be specifically tailored by Rotork to overcome problems around confined areas and tough entry.
IQ3 actuators and IS gearboxes had been mechanically tailored in order that each actuator and gearbox might be manually operated with out entering the confined space. เกจวัดแรงดันแก๊สlpg designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to eliminate the necessity for confined area access.
Actuators throughout the IQ vary are watertight, offering ingress protection to IP66/68 at 20 m for 10 days. They have a complicated dual stacked display with configurable information logger performance, and an absolute place sensor supplies reliability and accuracy.
