The WZPM2-08-107.5-M18-S assembled platinum resistance sensor is a high-precision temperature measurement element used in equipment such as steam turbines. It uses imported platinum resistance elements and has the characteristics of precision, sensitivity, fast response speed and long service life. This sensor is essential for monitoring the operating status of equipment and can provide accurate temperature data to ensure the safe operation of the equipment.

1. Mechanical fatigue problems caused by vibration

Vibration is a common phenomenon around mechanical equipment such as steam turbines, especially those that run at high speeds, and the vibration of nearby pipelines is particularly obvious. Vibration causes the sensor probe WZPM2-08-107.5-M18-S to be stressed. When the vibration frequency is close to the natural frequency of the sensor, resonance will occur, which will significantly increase the stress. Under the influence of this for a long time, the sensor probe material may have tiny cracks, eventually causing fatigue damage. This not only reduces the measurement accuracy, but may also damage the sensor and affect the normal operation of the entire monitoring system.

2. Reinforced installation method

(I) Optimize the installation structure

Set up a support frame near the installation point of the temperature sensor WZPM2-08-107.5-M18-S, and fix the sensor to the support frame through a flexible connector. This method helps to disperse the vibration stress transmitted to the sensor and reduce stress concentration. The support frame should be made of high-strength and high-toughness materials such as stainless steel to ensure stability.

Increase the number of fixing points In addition to fixing at the root of the probe, additional fixing points are also added in the middle and tail. This can build a more stable support system and reduce the shaking of the probe during vibration. The positions of these fixing points should be reasonably arranged according to the specific situation of the vibration.

(II) Choose the right material

Add cushioning materials such as rubber pads or polyurethane foam between the thermal resistance probe WZPM2-08-107.5-M18-S and the installation structure. These materials can absorb vibration energy and reduce direct impact on the probe. When selecting cushioning materials, their temperature resistance and chemical stability should be considered.

Use high-strength threaded connectors or welding materials to connect the sensor probe to the installation structure. These connectors must be able to withstand large tensile and shear forces to ensure that the probe will not loosen during vibration. Welding materials should have good fatigue resistance.

(III) Improve installation process

When installing the thermal resistance WZPM2-08-107.5-M18-S, attention should be paid to controlling the preload of the threaded connection. Use a torque wrench to operate according to the specified torque value to avoid uneven force or loosening of the probe due to improper preload.

According to the direction and intensity of pipeline vibration, the installation angle of the sensor probe should be properly adjusted so that its axis forms a certain angle with the vibration direction to reduce the direct impact of vibration on it. The optimal installation angle can be determined by experiment or simulation analysis.

The turbine monitoring system of a power plant has frequently encountered sensor failures due to strong pipeline vibration. After the technicians took the above reinforcement measures, including adding stainless steel support frames, adding fixing points, using rubber buffer pads, and strictly controlling preload, the sensor failure rate was greatly reduced and the service life was extended. This case demonstrates the effectiveness of these reinforcement methods and provides a reference for solving similar problems.

By optimizing the installation structure, carefully selecting materials and improving the installation process, the risk of mechanical fatigue of the WZPM2-08-107.5-M18-S platinum thermal resistance for steam turbines in a vibration environment can be effectively reduced. These measures are mainly used to disperse stress, absorb vibration energy and ensure reliable connections. In practical applications, the reinforcement scheme should be flexibly selected in combination with specific vibration conditions and working environments. At the same time, regular maintenance and monitoring are also key to ensuring stable operation of the sensor.
