Rotork has been working with BAE Systems to improve a sequence of A-range actuators to IQ3 actuators which operate penstocks controlling movement of ships between the sea and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A collection of A-range actuators had reached the end of their operational life after lengthy service in a challenging surroundings. BAE Systems wanted to retain all the advantages of electric actuators, so IQ3 actuators had been chosen. These had to be specially adapted by Rotork to beat problems round confined spaces and difficult entry.
IQ3 actuators and IS gearboxes had been mechanically adapted so that both actuator and gearbox might be operated by hand with out coming into the confined house. เกจวัดแรงดันลม designed special hand auto levers and thru drive mechanisms for the actuator and gearbox to get rid of the need for confined space access.
Actuators within the IQ range are watertight, providing ingress protection to IP66/68 at 20 m for 10 days. They have an advanced twin stacked display with configurable knowledge logger functionality, and an absolute position sensor supplies reliability and accuracy.
