Woodward E8250-826 Product Specification Document

Input Specifications

1.Power Supply: 24VDC (18~32VDC wide voltage range)

2.Control Signal Input: 4–20mA analog standard signal; 0–5VDC optional voltage signal

3.Discrete Input: 24VDC switch signal for emergency stop & position locking

4.Feedback Signal Input: Built-in position sensor feedback signal

Output Specifications

1.Mechanical Output: Counter-clockwise rotary stroke output

2.Executive Output: Proportional mechanical displacement linked with fuel rack actuator

3.Feedback Output: 4–20mA position feedback analog signal for closed-loop governing

Main Functions

1. Proportional fuel regulation: Convert governor electrical command into mechanical action to adjust fuel supply volume of prime mover

2.Closed-loop speed governing: Cooperate with Woodward digital governor to stabilize engine/turbine rotational speed

3. Load compensation: Real-time adjust output displacement to restrain speed fluctuation under dynamic load variation

4.Fail-safe protection: Maintain current execution position once control signal interruption occurs, prevent runaway failure of prime mover

5. Position closed-loop feedback: Real-time transmit actuator position signal to control system for precise position calibration

6. Emergency stop linkage: Match external stop signal to cut fuel supply for unit safety protection

Product Advantages

1.Ultra-high control precision: Strict proportional linear output ensures stable speed deviation within allowable range

2.Excellent environmental adaptability: Resist vibration, dust, humidity and temperature variation for long-term continuous operation

3.High reliability & low maintenance: Mature EG3P hydraulic structure, less wearing parts, prolong service cycle

4.Perfect compatibility: Matches all Woodward mainstream digital governor systems, easy system integration

5. Standard industrial signal: Adopt universal 4–20mA signal, compatible with third-party PLC & DCS control systems

6.Complete safety mechanism: Multi-layer fault protection design reduces unit downtime and operation risk

Application Cases

1.Power Generation Industry: Speed governing actuator for diesel generator sets, gas engine generator units in distributed power plants and standby power stations, realize grid-connected load sharing & constant frequency operation

2.Marine Industry: Main engine fuel control actuator for marine diesel propulsion units, stabilize navigation power output under wave load fluctuation

3.Petrochemical Industry: Turbine/diesel prime mover governing for oil & gas pumping compressors, guarantee continuous production equipment operation

4.Industrial Engine Field: Heavy-duty industrial diesel engine speed regulation for mining equipment, construction machinery fixed power units

5.Thermal Power Auxiliary Unit: Auxiliary engine governing for boiler auxiliary prime mover equipment

Core Characteristics

1.Operating Temperature Range: -40℃ ~ +85℃, stable operation under high/low temperature industrial environment
