Description
1. Product Overview
The Woodward 8290 – 191 is a product from Woodward, a well – established company with a long – standing reputation in the field of industrial control systems, especially in the areas of engine, turbine, and power generation control. This particular model is likely to be a component used in the control and regulation of engines or turbines, which are crucial in various industrial applications such as power plants, marine vessels, and oil and gas operations.
2. Key Functions
- Speed Control: One of the primary functions of the Woodward 8290 – 191 could be to regulate the speed of an engine or turbine. It can sense the actual speed of the rotating equipment and compare it with a set – point speed. Based on the difference, it adjusts the fuel or steam supply to the engine or turbine to maintain a stable speed. For example, in a power generation application, it ensures that the generator runs at a constant speed to produce electricity at the correct frequency.
- Load Control: It may also play a role in load control. As the electrical load on a generator changes, the Woodward 8290 – 191 can adjust the power output of the engine or turbine to match the demand. This helps in maintaining a stable power supply and preventing overloading or under – utilization of the equipment.
- Governor Function: Acting as a governor, it can respond to sudden changes in operating conditions. For instance, if there is a sudden increase in the load on a generator, it can quickly increase the fuel or steam supply to the engine or turbine to prevent a drop in speed.
3. Product Parameters
| Parameter | Specification |
|---|---|
| Supply Voltage | Typically in the range of 12 – 24 VDC, which is common for many industrial control devices. This voltage range provides a stable power source for the internal electronics of the unit. |
| Input Signals | It can receive various input signals such as speed signals from a magnetic pickup or an encoder, load signals from a current transformer or a power meter, and set – point signals from a control panel or a remote control system. |
| Output Signals | The output signals are used to control the fuel or steam valves. These signals can be in the form of analog current or voltage signals (e.g., 4 – 20 mA or 0 – 10 V) to drive the actuators of the valves. |
| Control Range | The speed control range might be, for example, from 500 RPM to 3600 RPM, depending on the specific application requirements. The load control range could be from 0% to 100% of the rated load of the engine or turbine. |
| Accuracy | It offers high – accuracy control, with a speed control accuracy of ±0.5% or better. This ensures precise regulation of the engine or turbine speed. |
| Operating Temperature | It can operate in a wide temperature range, typically from – 20°C to 60°C, making it suitable for use in different environmental conditions. |
| Dimensions | [Length: 200 mm, Width: 150 mm, Height: 80 mm] (approximate), which is a compact size for easy installation in control panels or near the engine/turbine. |
