RELIABLE THROTTLE SPEED CONTROL ON A MISSION
By combining two GAC ACB2001 actuators with an AXIOMATIC AX100310 Unidirectional Digital Control one of Coastguard Bluff’s rescue vessel’s finally has a reliable solution to a throttle speed control issue.
THE SOLUTION: GAC ACB2001 ACTUATOR
The Coastguard Bluff, charged with protecting the Foveaux Strait area of southern New Zealand hired Echo Mechanical Electrical Engineering (EEME) NZ Ltd to determine if it was possible to improve the reliability of their system.
Working as a team EEME, Governors America Corporation (GAC), Axiomatic Technologies, and the Bluff Coast Guard team as well as Gough Bros Ltd and Hamilton Jet NZ, determined the 500 HP Yanmar Engines Fuel Injection Pump Throttle Control Levers were not getting the high torque needed to move from idle to full throttle. They also realized the system must be proportional to the Bridge Speed Control Levers. With no space for additional equipment, the engine must remain original.
The solutions mounts a GAC ACB2001 actuator, capable of 35 degrees of rotation and up to 12 ft-lb [16.3 N∙m] torque, on a special bracket on each 500 HP Yanmar 6CXBM diesel engine, paired with the Axiomatic controller to replace the original equipment. This provides the coastguard rescue vessel with the reliable throttle speed control it needs to seamlessly control the vessel with the Blue Arrow jet controls without loss of control.
Governors America Corp will be closed September 6th in observance of Labor Day
ACB2001 HEAVY DUTY ACTUATOR
GAC’s ACB2001 actuator is a rotary output, 24 V, linear torque proportional electric servo designed for mechanical actuation of fuel system control levers requiring torques as high as 12 lb-ft [16.3 N∙m].
Paired with GAC’s ESD5300 Series speed control units, the actuator is capable of 35 degrees of rotation.
Internal springs provide fail safe operation by forcing the actuator to the fuel shut off position when the actuator is de-energized. Since the design has no sliding parts, and is totally sealed, its reliability is outstanding and no maintenance necessary. Engine applications include large block pumps, dual medium carburetors, and some large size carburetors.
