Rotork has been working with BAE Systems to improve a sequence of A-range actuators to IQ3 actuators which function penstocks controlling motion of ships between the sea and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A series of A-range actuators had reached the top of their operational life after long 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 round confined spaces and difficult entry.
pressure gauge หน้าปัด 4 นิ้ว and IS gearboxes were mechanically tailored so that both actuator and gearbox might be operated by hand without coming 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 area access.
Actuators inside the IQ vary are watertight, offering ingress protection to IP66/68 at 20 m for 10 days. They have an advanced twin stacked show with configurable knowledge logger performance, and an absolute position sensor supplies reliability and accuracy.
