WOODWARD 9907-1183｜Turbine Controller HMI｜
1. Anti pollution and high reliability
Adopting Silk Buster self-cleaning technology, it can withstand 40 μ m oil stains without the need for additional precision filtration, reducing maintenance costs.
The key components (valve core/valve sleeve) are made of 440C stainless steel, which is corrosion-resistant and wear-resistant, and suitable for Woodward turbine lubricating oil system.
When the power is cut off, the built-in return spring keeps the valve in a safe fully open bypass position, ensuring the safety of the unit.
2. Precise control and redundancy capability
Control accuracy: pressure stability<± 2% of set value, repeatability accuracy 0.1% of full range, temperature drift<± 0.01%/℃ Woodward.
Support dual machine redundant parallel connection (master/slave switching), configurable redundant pressure setting/feedback input, and improve availability in critical scenarios.
Scanning time of 2.5 ms, total response time of 10-30 ms, fast tracking of load/speed changes Woodward.
3. Interface and Diagnosis
Isolate I/O to resist electromagnetic interference, support local debugging interfaces, and configure parameters through upper level software.
Built in self diagnosis: Over range/fault signals can be configured as alarm/interlock shutdown, and LED indicator lights provide real-time feedback on status.
4.Application
Steam turbine: main steam valve and regulating valve servo pressure closed-loop control to ensure stable speed/load.
Gas turbine: precise adjustment of fuel/intake pressure to optimize combustion efficiency and safety.
Turbine generator set: multi unit load distribution, redundant control, suitable for power plants/industrial self owned power plants.
Ship Power: Reliable Valve Control for Ship/Marine Turbine Propulsion Systems Woodward.
