Rotork has been working with BAE Systems to upgrade a sequence of A-range actuators to IQ3 actuators which operate penstocks controlling motion of ships between the ocean 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 lengthy service in a challenging setting. BAE Systems wished to retain all the benefits of electrical actuators, so IQ3 actuators had been chosen. These had to be specially tailored by Rotork to beat issues round confined areas and difficult access.
IQ3 actuators and IS gearboxes have been mechanically adapted in order that each actuator and gearbox could be operated by hand without entering the confined space. Rotork designed particular hand auto levers and through drive mechanisms for the actuator and gearbox to eliminate the necessity for confined space entry.
Actuators inside the IQ range are watertight, providing ingress safety to IP66/68 at 20 m for 10 days. เกจวัดco2 have an advanced twin stacked show with configurable knowledge logger functionality, and an absolute place sensor offers reliability and accuracy.
