Woodward 8290-195 Flo-Tech Speed Control

Woodward 8290 - 195 Flo - Tech Speed Control is a speed control product produced by Woodward. Here are some introductions about it:

Features and Advantages

High-precision speed control: Using advanced control algorithms and sensor technology, it can monitor and accurately adjust the speed of the equipment in real time, control the speed within a very small error range, and ensure that the equipment can operate stably under different load conditions. For example, in some industrial production scenarios with high speed accuracy requirements, it can control the speed fluctuation within ±0.5%.

Fast response capability: It can respond quickly to sudden changes in load or other interference factors, and quickly adjust the output to maintain the set speed. It can usually respond to speed deviations within tens of milliseconds, effectively reducing speed fluctuations and improving system stability and reliability.

Flexible configuration options: It has a variety of input and output interfaces and can be easily connected and integrated with various types of engines, actuators and other control systems. Parameters can also be adjusted through software or hardware settings to meet different application scenarios and specific control requirements, and adapt to various industrial environments and working conditions.

Reliable fault diagnosis and protection function: The built-in complete fault diagnosis system can monitor its own working status and the operation of related equipment in real time. Once an abnormality is detected, such as sensor failure, power failure or control algorithm error, it can quickly send out an alarm signal and take corresponding protection measures, such as limiting the speed and cutting off the power, to avoid equipment damage and accidents, and ensure the safety of equipment and personnel.

Working principle

Generally speaking, Woodward 8290 - 195 Flo - Tech Speed Control obtains the actual speed signal of the equipment in real time through the speed sensor and compares it with the internally set target speed value. When the actual speed deviates from the set value, the controller calculates the required control amount according to the size and direction of the deviation and a specific control algorithm (such as PID algorithm), and then outputs the corresponding control signal to the actuator (such as fuel regulating valve, intake control valve or motor driver, etc.) to adjust the engine's fuel supply, intake volume or motor drive current, so that the equipment speed can quickly and accurately return to the set target speed value, and achieve precise control of the equipment speed.

Application areas

Power generation: widely used in diesel generator sets and gas turbine generator sets to ensure that the generator can run at a stable speed under different loads, thereby ensuring the stability of the frequency and voltage of the output power and meeting the power supply requirements of the power grid. In some small power stations or emergency backup power supply systems in remote areas, it can reliably maintain the stability of power supply.

Industrial drive: used to drive the engine or motor of large compressors, fans, pumps and other industrial equipment to ensure that the equipment can run at a constant speed under various working conditions and improve the stability and efficiency of the industrial production process. For example, in the production process of chemical, petroleum, metallurgy and other industries, it can ensure the stable operation of key links such as fluid transportation and gas compression.

Ship power: Provide speed control for the ship's diesel engine or gas turbine to ensure that the ship can maintain a stable propulsion speed during navigation, regardless of any sea conditions or load changes, to ensure the safety and performance of the ship's navigation. Whether it is a merchant ship, a warship or a yacht, all types of ships can achieve reliable power control with the help of this speed controller.
