The significance of vibration sensors in the application of turbines

Turbines, as widely used rotating mechanical equipment, play a crucial role in multiple fields such as power generation, aerospace, and shipping. The stability and reliability of their operation are directly related to the safety and efficiency of the entire production system. The introduction of vibration sensors provides strong technical support for the condition monitoring and fault diagnosis of turbines.-Dedicated turbine sensor

The Importance of Turbine Vibration Monitoring

During operation, turbines are subject to various factors that can cause varying degrees of vibration, such as imbalance, misalignment, bearing wear, and blade damage. If these vibrations are not promptly monitored and addressed, they may lead to equipment damage and even serious safety incidents. For instance, blade vibration fatigue fractures can cause rotor imbalance, which in turn can trigger severe vibration throughout the entire unit, ultimately resulting in equipment failure and shutdown. Therefore, real-time monitoring of turbine vibration is a crucial step in ensuring safe operation.

The principle of vibration sensors

Vibration sensors are devices that can convert mechanical vibrations into electrical signals. They are mainly used to monitor the vibration conditions of bearing housings, machine casings, or mechanical structures. For rotors supported by rolling bearings, their vibrations are transmitted to the bearing housing. Vibration sensors installed on the machine base or close to the casing can measure the vibration of rotating or reciprocating machinery (i.e., absolute vibration relative to free space) and transmit the signals to detection instruments to achieve prediction and early warning of mechanical faults.

The installation positions of vibration sensors in turbines

To comprehensively monitor the vibration conditions of turbines, vibration sensors need to be installed at key locations. Generally, the installation positions of sensors include the bearing housing of the rotor, the casing, the blades, etc. Installing sensors at the bearing housing can effectively monitor the radial and axial vibrations of the rotor, and promptly detect problems such as bearing wear and misalignment; installing sensors on the casing can monitor the vibration of the casing and understand the overall operating status of the equipment; for some large turbines, micro sensors can also be installed on the blades to directly monitor the vibration of the blades, so as to promptly detect blade damage and loosening, etc. By installing vibration sensors at these key positions, all-round monitoring of turbine vibration can be achieved.

The Role of Vibration Sensors in Turbine Maintenance

The introduction of vibration sensors has brought numerous conveniences to the maintenance of turbines. Through real-time monitoring and analysis of vibration data, maintenance personnel can promptly understand the operational status of the equipment, identify potential fault risks in advance, and thereby formulate reasonable maintenance plans to prevent sudden equipment failures and shutdowns. For instance, when vibration sensors detect abnormal vibration signals from bearings, maintenance personnel can schedule bearing inspections or replacements in advance, reducing equipment maintenance costs and downtime. Additionally, vibration sensors can also be used for equipment performance evaluation and optimization. By long-term monitoring and analysis of vibration data, the operational performance of the equipment under different working conditions can be understood, providing a basis for equipment optimization design and adjustment of operating parameters.

Vibration sensors in turbines can not only effectively monitor the vibration conditions of the turbines and promptly detect potential equipment faults, but also provide strong support for equipment maintenance and optimization. With the continuous development of sensor technology and the increasingly improved data analysis methods, the application of vibration sensors in turbines will become more extensive and in-depth, playing a greater role in ensuring the safe, stable and efficient operation of turbines.
