1. What is the principle of the sudden jump thermostat?
The sudden jump thermostat is a kind of thermostat, which is a series of automatic control elements that are physically deformed inside the switch according to the temperature change of the working environment, resulting in some special effects and on-off action. The sudden jump thermostat is a kind of bimetal disc after constant temperature as a heat-sensitive reaction component, when the temperature of the main part of the product increases or decreases, the heat generated is transferred to the bimetal disc, and when the action temperature is set, it acts quickly, and the contact is disconnected or closed through the action of the mechanism, so as to achieve the purpose of turning on or disconnecting the circuit, so as to control the circuit.
2. How to judge the quality of the sudden jump thermostat
1. Temperature sensing speed. The temperature sensing speed of the sudden jump thermostat needs to match the power of the heating product, the greater the power and the faster the heating, then it is necessary to think about the temperature sensing time of the thermostat and accurately select the temperature section, and the thermostat needs to have the characteristics of fast temperature sensing, fast action, and no arcing.
2. The heating of the thermostat itself, the copper data inside the current thermostat, the heating of different copper materials is not the same, if the heat of the data used is large, it will affect the temperature sensitivity of the bimetal sheet. In this way, it is necessary to choose a thermostat with no current thermal effect planning, accurate temperature and long life.
3. The device of the thermostat. The temperature sensing of the temperature control switch is based on the aluminum cover sealed on the surface and then added to the internal air of the thermostat, or the heat is radiated to the temperature sensing body through the aluminum cover, so the device should make the product close to the device surface of the controlled appliance. Then it is also necessary to think about the device, not to vigorously collapse or deform the shell, so as not to affect its function.
3. Precautions for the installation of sudden jump thermostats
1. When the contact temperature sensing installation is adopted, the metal upper cover plane of the temperature switch should be completely close to the installation surface of the controlled tool. In order to ensure the temperature sensing effect, apply thermal paste to the temperature sensing surface of the appliance.
2. Do not crush, loosen or deform the top of the metal surface of the temperature switch during installation, so as not to affect the function and precision. Do not allow liquids to penetrate the inside of the temperature switch or cause cracks in the housing due to excessive force.
3. Do not change the shape of the external terminal at will, so as not to affect the electrical reliability, and there are insulation protection measures to prevent leakage and ensure the safety of use.
