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 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 top of their operational life after long service in a challenging environment. เกจวัดความดันน้ำ needed 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 spaces and troublesome access.
IQ3 actuators and IS gearboxes were mechanically tailored so that both actuator and gearbox could be operated by hand with out getting into the confined area. Rotork designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to remove the necessity for confined house entry.
Actuators within the IQ vary are watertight, offering ingress protection to IP66/68 at 20 m for 10 days. They have a complicated twin stacked show with configurable knowledge logger performance, and an absolute position sensor offers reliability and accuracy.
