GE IC3600SSVF1 Servo Valve Feedback Card

الوصف

The GE part number IC3600SSVF1 is a Servo Valve Feedback Card. This specialized electronic circuit board is a component of GE’s legacy Speedtronic Mark I and Mark II series of turbine control systems. Its primary function is to enable closed-loop control by receiving position signals from a servo valve and feeding them back to the main control logic.

Function and Key Features

A servo valve controls the flow of fluid (fuel or steam) to a turbine’s actuators, regulating its speed, power output, and other parameters. For precise and safe operation, the control system needs to know the exact position of this valve at all times. This is the role of the feedback card.

• Feedback Signal Processing: The card takes a signal from a position sensor (such as an LVDT) on the servo valve. This signal, which represents the valve’s actual position, is then conditioned and transmitted to the main controller.
• Closed-Loop Control: By constantly comparing the actual position (from the feedback card) to the desired position (the command signal), the system can make continuous adjustments. This ensures the valve’s position is always accurate and responsive, which is essential for maintaining turbine stability.
• Protection: The card helps to prevent mechanical overshoot or drift, ensuring that the valve does not exceed its safe operating limits.
• System Integration: It is a critical link between the mechanical components of the turbine and the electronic control system, enabling real-time adjustments for optimal efficiency and safety.
