WOODWARD 8273-140

Description

1. Product Overview

2. Function and Working Principle

• Function: The primary function of the WOODWARD 8273 – 140 is to control the fuel flow to an engine or turbine. By precisely adjusting the fuel input, it can maintain the desired speed, load, and power output of the prime mover. It also helps in ensuring stable operation under different operating conditions, such as varying loads and environmental factors.
• Working Principle: The device uses a combination of sensors and control algorithms. Sensors measure parameters like engine speed, pressure, and temperature. Based on the input from these sensors, the 8273 – 140 compares the actual values with the setpoints. Then, it calculates the appropriate amount of fuel that needs to be supplied to the engine or turbine and sends signals to the fuel – control valves to adjust the flow accordingly.
