Rotork has been working with BAE Systems to improve a sequence of A-range actuators to IQ3 actuators which function penstocks controlling movement 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 end of their operational life after lengthy service in a difficult setting. BAE Systems wished to retain all the benefits of electrical actuators, so IQ3 actuators have been chosen. These had to be specially adapted by Rotork to overcome issues around confined spaces and tough entry.
IQ3 actuators and IS gearboxes were mechanically tailored so that each actuator and gearbox could possibly be manually operated 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 space access.
Actuators throughout the IQ vary are watertight, offering ingress safety to IP66/68 at 20 m for 10 days. จำหน่ายเกจวัดแรงดัน have a complicated dual stacked show with configurable knowledge logger functionality, and an absolute place sensor supplies reliability and accuracy.
