Rotork has been working with BAE Systems to upgrade a sequence of A-range actuators to IQ3 actuators which function penstocks controlling motion of ships between the ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A series of A-range actuators had reached the end of their operational life after long service in a difficult surroundings. BAE Systems wanted to retain all the benefits of electrical actuators, so IQ3 actuators were chosen. These had to be specially adapted by Rotork to beat issues around confined spaces and difficult entry.
IQ3 actuators and IS gearboxes were mechanically adapted so that both actuator and gearbox could be manually operated with out coming into the confined space. Rotork designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to remove 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. เกจวัดแรงดันปั๊มลมpuma have a complicated dual stacked display with configurable data logger performance, and an absolute position sensor supplies reliability and accuracy.
