In thermal power plants, temperature monitoring of various equipment is an important means to ensure the normal operation of equipment and prevent failures. WSS-481 bimetallic thermometer has been widely used in thermal power plants with its high precision, high stability and good adaptability.

1. Basic principles and characteristics of WSS-481 bimetallic thermometer

WSS-481 bimetallic thermometer is a temperature measuring instrument based on the principle of bimetallic strips. It consists of two or more metal sheets with different linear expansion coefficients stacked together to form a multi-layer metal sheet, and is made into a spiral roll shape. When the temperature changes, the expansion or contraction of each layer of metal sheet is different, causing the spiral roll to roll up or loosen. Since one end of the spiral roll is fixed and the other end is connected to the pointer, when the temperature changes, the pointer will indicate the corresponding temperature value on the circular graduation scale.

In thermal power plants, the application of WSS-481 bimetallic thermometer has the following advantages:

• High-precision measurement: ensure the accuracy of temperature monitoring and improve the reliability and stability of equipment operation.
• Easy to install and maintain: The WSS-481 bimetallic thermometer has a simple structure, easy installation and low maintenance cost.
• Strong adaptability: It is suitable for various harsh environments, such as high temperature, high pressure, corrosion, etc.
• Remote signal function: After being equipped with a temperature transmitter, the remote electrical signal function can be realized, which is convenient for remote monitoring and management.

2. Application of WSS-481 bimetallic thermometer in thermal power plants

In thermal power plants, WSS-481 bimetallic thermometer is suitable for temperature monitoring of various equipment, including but not limited to the following aspects:

1. Boiler system

The boiler is one of the core equipment of a thermal power plant, and its temperature monitoring is crucial. The WSS-481 bimetallic thermometer can be used to monitor the temperature of key parts such as the boiler body, burner, superheater, and reheater. For example, on the boiler body, the WSS-481 bimetallic thermometer can monitor the furnace temperature in real time to ensure that the fuel is fully burned, while preventing the furnace from overheating and improving the thermal efficiency of the boiler. In the superheater and reheater, the WSS-481 bimetallic thermometer can monitor the steam temperature to ensure that the steam operates within the specified temperature range and prevent overheating from damaging the equipment.

2. Steam turbine system

The steam turbine is a key device in a thermal power plant that converts steam thermal energy into mechanical energy. In the steam turbine, the WSS-481 bimetallic thermometer can be used to monitor the temperature of key components such as the cylinder, rotor, and bearing. The cylinder and rotor are the main force-bearing components of the steam turbine, and their temperature monitoring is of great significance for preventing overheating, wear and deformation. The WSS-481 bimetallic thermometer can monitor the temperature of these components in real time to ensure that the steam turbine operates under safe and efficient conditions. At the same time, bearing temperature monitoring is also essential, because overheating of the bearing will lead to poor lubrication, increased wear, and even equipment failure.

3. Generator system

The generator is a device in a thermal power plant that converts mechanical energy into electrical energy. In the generator, the WSS-481 bimetallic thermometer can be used to monitor the temperature of key parts such as the stator, rotor, and cooling system. The stator winding and rotor winding are the core components of the generator, and their temperature monitoring is of great significance for preventing overheating, insulation damage and short circuit failures. The WSS-481 bimetallic thermometer can monitor the temperature of these components in real time to ensure that the generator operates under safe and stable conditions. In addition, temperature monitoring of the cooling system is also essential, because abnormal temperature of the cooling system will affect the heat dissipation effect of the generator, and then affect the output power and stability of the generator.

4. Cooling system

The cooling system plays a role in heat dissipation and maintaining stable equipment temperature in thermal power plants. The WSS-481 bimetallic thermometer can be used to monitor the temperature of media such as cooling water and lubricating oil. The temperature monitoring of cooling water is of great significance for preventing equipment overheating and poor cooling. By real-time monitoring of the temperature of cooling water, the operating status of the cooling system can be adjusted in time to ensure that the equipment operates within the specified temperature range. At the same time, temperature monitoring of lubricating oil is also essential, because too high a temperature of lubricating oil will lead to poor lubrication, increased wear, and even equipment failure.

5. Pipes and valves

In the steam, water and fuel systems of thermal power plants, pipes and valves are key components for connecting and regulating various equipment. WSS-481 bimetallic thermometer can be used to monitor the temperature of pipes and valves to prevent leakage and damage. By real-time monitoring of the temperature of pipes and valves, temperature anomalies can be detected in time and corresponding measures can be taken to ensure the safe operation of the system.
