Description
Based on my previous searches and the information available online, the Woodward 9907-162 appears to be a 505 digital governor turbine control module used in industrial applications for steam turbines. Here’s a breakdown of its key characteristics:
Function:
- The 9907-162 is designed to electronically control and regulate the speed and power output of a steam turbine in an industrial power plant or other applications.
- It likely accomplishes this by:
- Receiving sensor inputs for parameters like speed, pressure, and temperature.
- Processing these signals using its internal control algorithms.
- Sending control signals to valves or other actuators to adjust steam flow into the turbine, thereby regulating its speed and power output.
Features (based on similar models):
- Digital Control: The “505 digital governor” designation suggests it utilizes a digital microprocessor for control functions, offering precise and reliable operation compared to traditional mechanical governors.
- Steam Turbine Applications: The module is specifically designed for governing steam turbines, likely compatible with single extraction or admission applications (where steam is extracted at one or more stages for process heating).
- Field Programmable: Some resources suggest the 9907-162 might be field-programmable, allowing customization of its control algorithms to match the specific requirements of the turbine and application.
Applications (within industrial power plants):
- Turbine speed and power control: Maintaining the desired speed and power output of the steam turbine for electricity generation or mechanical drive applications.
- Process control: In cogeneration plants, the 9907-162 might help regulate steam extraction for industrial process heating purposes.
- Safety control: The control module might also incorporate safety features to protect the turbine from overspeed or other operating conditions.
