How to maintain the air duct heater!
In the maintenance of air duct electric heaters, the first thing to master is how to protect the equipment. In daily life, especially in northern regions, it is necessary to take anti freezing measures for equipment. After the dry season or flood, the sand and soil covering the equipment will fall off, and it is necessary to backfill before winter to prevent damage to the equipment due to the thin soil layer.
When using the equipment, pay attention to the operating methods and check it in a timely manner. If the parts are severely worn, they should be replaced in a timely manner and attention should be paid to the cleanliness of the equipment. Firstly, pay attention to the high power density of the device itself. If the heat transfer is too poor and the equipment cannot transfer heat in a timely manner, it will cause the surface of the equipment to be burned black. Moreover, if the internal high temperature is accelerated, the hot wire will quickly age or even break, posing a danger to use.
Explosion proof electric heating strips can replace traditional high-energy consumption heat tracing methods!
Due to the climate and environmental factors in China, the demand for industrial temperature compensation heating and antifreeze insulation is increasing. The traditional methods of coal, hot water, and steam heating are no longer suitable for the development of the times, nor for the trend of energy conservation and environmental protection. Explosion proof electric heating belts can completely replace the traditional, high-energy consumption heat tracing methods mentioned above.
The electric heating belt is powered by clean electricity and heats the required equipment through its own heating principle. No damage to the environment, no emissions, and relatively low investment costs. At least one of the best heating methods currently available.
What is the principle of measuring thermal resistance!
Thermal resistance is used to measure the variation of temperature with the resistance of a metal conductor or semiconductor. The heating part of the thermal resistance (temperature sensing element) is uniformly wound on a frame made of insulating material made of metal wire, or formed on a substrate through laser sputtering process.
When the measured medium has a temperature gradient, the measured temperature is the average temperature of the medium layer within the range of the temperature sensor. Thermocouples, like thermal resistors, are sensors that measure temperature. However, the difference between thermocouples and thermal resistances is the list page of magnetic flap level gauges.
