Bimetal spring is a kind of mechanical thermometer, which is composed of two metal sheets with different expansion coefficients. It mainly realizes temperature measurement and control through spring sheets laminated by different metals.
The following is a detailed introduction to the characteristics and usage scenarios of bimetallic springs from three aspects: product introduction, working principle and application.
1. Product introduction In order to realize temperature detection, some temperature measurement tools are usually required, such as electronic thermometers, infrared thermometers and so on. The bimetallic spring is a mechanical thermometer, which has the characteristics of simple structure, low price, good stability, and wide applicable temperature range. Its main components are composed of two metal sheets with different expansion coefficients, and are fixed by a constant force spring. When the temperature changes, the expansion coefficients of different metals are different, resulting in deformation of the spring, which is converted into the movement of the pointer to express temperature information.
2. Working principle For bimetallic springs, the working principle is based on the thermal expansion properties of different metals, so the metal required is generally closely matched to the environment in which the product is manufactured. When the temperature changes, the spring leaf will produce bending deformation, and the mechanical transmission device will convert the deformation into the movement of the pointer, so as to realize the temperature measurement.
3. Application scenarios Bimetallic springs are widely used in manufacturing, home appliances and electronics, ship aviation and scientific research and other fields:
1). Industrial manufacturing: mainly used in occasions that need to monitor temperature changes, such as power plants, chemical plants, furnace temperatures, workshops, etc.
2). Household appliances and electronics: Mainly used in temperature detection and control of air conditioners, heaters, ovens and other household appliances and electronic equipment.
3). Ships and aviation: mainly used in temperature control of high-end products, such as spacecraft, aircraft, etc.
4). Scientific research experiments: It is also widely used in scientific research experiments to measure temperature changes, such as chemical experiments, biological experiments, etc.
Generally speaking, the bimetallic spring has the advantages of high measurement sensitivity, fast response speed, long service life, and simple structure. It is widely used in various industries and is an economical and practical temperature measurement tool.
