Rotork has been working with BAE Systems to improve a sequence of A-range actuators to IQ3 actuators which operate penstocks controlling motion of ships between the sea and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
เครื่องมือที่ใช้วัดความดันโลหิต of A-range actuators had reached the end of their operational life after lengthy service in a challenging environment. เกจวัดแรงดันน้ำมันเครื่อง needed to retain all the benefits of electrical actuators, so IQ3 actuators had been chosen. These needed to be specifically tailored by Rotork to overcome problems round confined spaces and difficult access.
IQ3 actuators and IS gearboxes have been mechanically adapted so that both actuator and gearbox might be operated by hand with out entering the confined space. Rotork designed particular hand auto levers and through drive mechanisms for the actuator and gearbox to get rid of the need for confined area access.
Actuators within the IQ range are watertight, providing ingress protection to IP66/68 at 20 m for 10 days. They have a complicated dual stacked display with configurable data logger functionality, and an absolute place sensor offers reliability and accuracy.
