Description
Woodward 1766-541
Technical Specifications
- Brand: Woodward
- Part Number: 1766-541
- Product Type: Electro-Hydraulic Servo Motor
- Series: SMM40
Functional Features
- High Force Output: Capable of overcoming high back-pressures and mechanical friction in large engine linkages.
- Fail-Safe Integration: Often configured with spring-return or fail-safe hydraulic circuits to secure the engine during emergencies.
- Smooth Modulation: Provides continuous, stepless positioning rather than discrete open/close actions.
Application Scenarios
Utilized in power generation diesel engines, marine main engines, and industrial gas turbines requiring precise fuel metering.
Performance Parameters
- Stroke/Travel: Customized stroke length to match specific engine fuel rack requirements.
- Leakage Rate: Minimal internal and external leakage for efficient hydraulic operation.
Material Composition
Heavy-duty metallurgy for the cylinder and piston, corrosion-resistant coatings, and premium elastomeric seals.
Structural Characteristics
Compact industrial design featuring standardized SAE or ISO hydraulic connections and a durable mechanical output shaft.
Working Principle
Operates as a linear hydraulic motor where the volume of oil admitted to the cylinder dictates the piston’s position, continuously corrected by a position feedback transducer.
Installation Requirements
Securely mount the actuator to a rigid foundation. Align the output linkage perfectly with the engine’s control shaft.
Usage Precautions
Always depressurize the hydraulic system before performing maintenance. Inspect linkages regularly for wear or looseness.
