WOODWARD A8516039 Steam Turbine Mechanical-hydraulic Governor

Description:

The WOODWARD A8516039 Current-to-Pressure Converter, also known as the CPC-II, is a specialized electro-hydraulic pressure regulating control valve designed for industrial applications. Here are the key features and details about this product:

Key Features

1. Functionality:
   • The CPC-II is a second-generation current-to-pressure converter (CPC-II) that accepts a 4-20 mA pressure demand signal and accurately controls the oil pressure to precisely position single-acting steam turbine governor valves.
   • It is used for electro-hydraulic pressure regulation in control valves for single-acting steam turbine valve servos/actuators.
2. Enhanced Performance:
   • The CPC-II offers enhanced dynamic performance, addressing one of the major reliability issues in the industry—oil pollution—which can affect the normal running time and performance of equipment.
   • It provides precise and stable steam valve control, which is crucial for speed and load control of steam turbines and for reducing system mechanical wear.
3. Technical Specifications:
   • Input Voltage: Typically 24V DC (though some sources mention 125V DC as a possible variant, 24V DC is more commonly cited).
   • Output: Provides a precise and stable pressure output proportional to the input current.
   • Working Temperature Range: Generally operates within -40°C to 70°C, though some specifications mention ranges up to -40°C to +85°C or -40°C to +100°C, depending on the application and manufacturer’s guidelines.
   • Precision: Achieves high accuracy in position control (±0.1%) and speed control (±0.1%).
   • Response Time: Typically ≤2ms, with some sources mentioning response times less than 1ms.
   • Control Range: Position control from -60° to +60°, speed control from 0 to 6000 RPM, and torque control from 0 to 10 Nm.
4. Physical Characteristics:
   • Dimensions: Approximately 120mm x 60mm x 80mm (specific dimensions may vary based on product usage).
   • Weight: Around 25 kg when used as an electro-hydraulic converter.
5. Connectivity and Communication:
   • Communication Interfaces: May include HDMI or other industrial standard interfaces, depending on the manufacturer and configuration.
   • Compatibility: Highly compatible with most WOODWARD PLC systems and can achieve limited compatibility with some other brands through specific conversion modules.
6. Reliability and Maintenance:
   • The CPC-II is designed for high reliability, with features like redundant input/sensors (including a valve linearization table with full-scale <0.2% accuracy) to enhance system reliability and accuracy.
   • It is easy to install and maintain, with the ability to mount on various brackets when sufficient support is provided.

Applications

• The WOODWARD A8516039 CPC-II is widely used in industries such as energy, oil and gas, aviation, aerospace, and industrial manufacturing for monitoring and controlling various mechanical and electronic systems.
• It is particularly suited for applications requiring precise control of steam turbine valves, such as in power generation plants, industrial turbines, and other critical control systems.
