The displacement sensor 5000TD-XC3 plays a vital role in ensuring the safety of turbine operation, which is mainly reflected in the following aspects:

1. Turbine rotor axial displacement monitoring: By installing it at the bearing seat or shaft seal at both ends of the turbine, the 5000TD-XC3 can monitor the axial displacement of the rotor in real time, which is crucial to prevent collisions between the rotor and stationary parts. Abnormal increase in axial displacement may be a sign of rotor imbalance, bearing wear or sudden changes in steam conditions. Timely detection and measures can avoid serious mechanical damage.

2. Cylinder expansion monitoring: During the operation of the turbine, high-temperature steam will cause the cylinder to expand. The 5000TD-XC3 can be used to monitor the expansion of the cylinder relative to the base or fixed structure to ensure that the expansion is within the design allowable range, avoid stress concentration or seal failure caused by uneven expansion, and thus ensure the integrity of the turbine structure.

3. Valve position monitoring: In addition to the oil motor stroke, 5000TD-XC3 can also be used to monitor the opening and closing positions of the main steam valve, regulating valve and other important valves of the steam turbine to ensure that the valve action is accurate and responds to the control system command in a timely manner, which is extremely critical for regulating steam flow, maintaining turbine load and preventing abnormal operating conditions such as overspeed.

4. Vibration monitoring: In some applications, through a specially designed installation method, 5000TD-XC3 can be used indirectly to monitor the vibration level of the steam turbine and its key components. By measuring the displacement changes caused by vibration, the operating status of the equipment can be evaluated to prevent mechanical fatigue damage or destruction caused by excessive vibration.

5. Fault diagnosis and prevention: By continuously collecting and analyzing the data output by 5000TD-XC3, combined with advanced data analysis technology, fault mode identification and predictive maintenance can be performed to detect potential problems in advance, avoid sudden failures, reduce maintenance costs, and improve equipment availability and safety.

6. Environmental adaptability and long-term stability: Its stainless steel material and good packaging design enable 5000TD-XC3 to work stably in harsh environments such as high temperature, high humidity, oil pollution, vibration, etc., reducing the failure rate of the sensor itself, indirectly ensuring the reliability of the entire monitoring system and the safe operation of the steam turbine.

In summary, the displacement sensor 5000TD-XC3 is used in many aspects of steam turbines, not only limited to the oil motor stroke monitoring, but also fully participates in the protection system of steam turbines, from monitoring, early warning to fault prevention, and then to the maintenance of long-term stable operation, which comprehensively improves the safety and reliability of steam turbines.
