What is the energy-saving principle of electric heating tape?

　　In today's energy scarcity and environmental protection requirements increasingly strict background, energy saving has become an important topic in all walks of life. Electricity accompanies the tropical as a new type of pipeline heat preservation and anti-freezing programme, because of its high efficiency and energy saving, environmental protection and safety advantages, gradually be widely used in petroleum, chemical industry, electric power, metallurgy, light industry, food, refrigeration, construction, gas, agricultural and sideline products production, processing and so on many fields.

　　So, what is the principle of energy saving of electric accompanied by tropical? This article will be discussed from a variety of perspectives.

　　First, the self-limiting temperature characteristics

　　The core material of electric accompanied by tropical is conductive polymer composite material, has the positive temperature coefficient ‘PTC’ characteristics. This characteristic means that the resistivity of the material with the rise of temperature and increase, and in a certain temperature range of resistivity increases sharply. When the temperature around the heating tape becomes cold, the conductive plastic produces a contraction of the micro-molecules so that the carbon particles are connected to form circuits, and the electric current passes through these circuits, causing the heating tape to heat up. When the temperature rises, the conductive plastic produces the expansion of the micro-molecule, the carbon particles gradually separate, cause the interruption of the circuit, the resistance rises, accompanied by the heat will automatically reduce the power output. This kind of self-limiting characteristic makes the electric accompanying heat belt can adjust the output power automatically according to the ambient temperature, avoiding the overheating and energy waste.

　　Second, accurate temperature control

　　The electric accompanies the tropical belt through the temperature control system to realise to the pipeline and the equipment temperature precise control. Traditional accompanying heat method often can not guarantee the uniformity and stability of temperature, easy to cause energy waste. And the electric accompanies the tropical belt to be able to achieve the ideal accompanying heat effect through the temperature control system. This precise temperature control not only improves the energy utilisation efficiency, but also avoids the heat waste and leakage problem in the traditional accompanying heat method.

　　Third, uniform heat distribution

　　The electric accompanies the tropical heat generating element to be uniformly distributed in the whole accompanies the tropical strip on, can provide the uniform heat distribution. The traditional accompanying heat method often exists the problem that the heat distribution is not even, causes part of the area to overheat and part of the area temperature is not enough. The electric accompanies the heat of the heat distribution uniformly makes the temperature of the pipeline and the equipment more uniform, avoids the local overheating and the energy waste.

　　Fourth, reduce the heat dissipation area of heat preservation layer

　　The electric accompanies the tropical appearance small, will not change the pipeline heat preservation form, laying the heat dissipation surface is small. The traditional accompanying heat heating needs to increase the accompanying heat steam pipe or hot water pipe, will increase the heat dissipation area of the heat preservation layer, increase the heat dissipation. And the use of electric accompanied by tropical can effectively reduce the heat dissipation area of the heat preservation layer, reduce the heat dissipation, improve the efficiency of energy use.

　　Five, intelligent management

　　The electric accompanies the tropical belt to be able to realise the remote monitoring and management through the intelligent management system. The traditional accompanying heat method often needs artificial operation and maintenance, easy to appear operation error and maintenance improper problem. The intelligent management system of electric accompanied by tropical can realise the function of remote monitoring, automatic adjustment and fault alarm, etc. It improves the operation efficiency and safety of the system and reduces the cost of manual operation and maintenance.

　　Six, environmental protection and safety

　　The electric accompanied by the tropical adopts the electric energy as the energy source, will not produce the harmful gas and the pollutant, conforms to the environmental protection requirement. The traditional accompanying heat method often need to use fuel or steam, easy to produce harmful gases and pollutants, cause pollution to the environment. The use of electric accompanied by tropical can effectively reduce the emission of pollutants, protect the environment.

　　To sum up, the energy-saving principle of electric accompanied by tropical mainly embodies in the self-limiting temperature characteristics, precise temperature control, uniform heat distribution, reduce the heat dissipation area of the insulation layer, intelligent management and environmental protection and safety. These characteristics make the electric accompanied by the tropical to become a kind of high efficiency and energy saving, environmental protection and safety of the pipeline heat preservation and anti-freezing programme, has a wide range of application prospects. With the continuous progress of science and technology and environmental protection requirements of the increasingly strict, electric accompanied by tropical application will be more and more extensive, for all walks of life of energy saving and environmental protection to make greater contributions.
