Solar electric heat tracingIt is a kind of thermal insulation product that uses solar power generation, which can effectively solve the problem of freezing pipes, equipment and containers in a low temperature environment to ensure the normal progress of production and life. However, there are also some potential risks associated with the use of solar power heat tracing, which may lead to safety accidents such as fire and leakage if not used in a standardized manner.
Therefore, the following is an introduction to the standard use of solar electric heat tracing to help you use this product correctly and avoid unnecessary losses.
1. Choose the right product.
When choosing a solar electric heat tracing, it is necessary to determine the appropriate model and specifications according to the material, size, ambient temperature and other parameters of the object to be heated. Generally speaking, the selection of solar electric heat tracing should consider the following aspects:
1.Heating power: Heating power refers to the amount of heat generated per unit of time, generally measured in W m. The higher the heat generation, the better the heat tracing, but also the more electricity is consumed. Therefore, it is necessary to determine the appropriate heat generation power according to the heat dissipation of the object to be heated.
2.Maximum Maintenance Temperature: The maximum maintenance temperature refers to the maximum temperature that a solar electric heat trace can maintain under certain conditions. The higher the maximum holding temperature, the better the heat tracing effect, but it also increases the temperature change of the object to be heated. Therefore, it is necessary to determine the appropriate maximum maintenance temperature according to the material and operating temperature of the object to be heated.
3.Maximum service length: The maximum service length refers to the longest distance that the solar electric heat trace can work continuously under certain conditions. The longer the maximum length of use, the larger the heat tracing range, but it will also reduce the heating efficiency. Therefore, it is necessary to determine the appropriate maximum length of use according to the layout of the object to be heated and the power supply conditions.
4.Explosion-proof level: Explosion-proof level refers to the ability of solar electric heat tracing to prevent ** under certain conditions. The higher the explosion-proof rating, the higher the safety, but it also increases the cost. Therefore, it is necessary to determine the appropriate explosion-proof level according to the use environment and explosion-proof requirements of the object to be heated.
Second, install the product correctly.
When installing a solar heat tracing, the following steps need to be followed:
1.Clean the surface of the object to be heated, remove oil, dust and other debris to ensure that the surface is dry, flat and smooth.
2.According to the design requirements, the solar electric heat trace is wound on the object to be heated, pay attention to maintain a certain spacing and tension, and avoid overlapping, crossing, twisting and other phenomena.
3.Use special tape or clips to fix the solar electric heat trace on the object to be heated, pay attention to the material and specifications of the tape or clip to match the solar electric heat trace to avoid sparks or leakage.
4.Connect the two ends of the solar electric heat trace to the power supply device, pay attention to the reliability and safety of the connection, and avoid poor contact or short circuit.
5.Cover the surface of the solar electric heat tracing with a layer of thermal insulation material, and pay attention to the thickness and density of the thermal insulation material to be adapted to the object to be heated, so as to avoid heat loss or overheating.
6.Install a temperature sensor at every certain distance at both ends and in the middle of the solar electric heat tracing, and pay attention to the position and accuracy of the temperature sensor to match the object to be heated, so as to avoid misjudgment or loss of control.
7.Install a leakage protector at every certain distance at the beginning and end of the solar electric heat trace and in the middle, and pay attention to the rated current and action time of the leakage protector to match the solar electric heat trace to avoid leakage or overload.
8.Install a grounding device at every certain distance at both ends and in the middle of the solar electric heat tracing, and pay attention to the grounding resistance of the grounding device to meet the national standards to avoid electric shock or lightning strike.
3. Reasonable use of products.
When using solar heat tracing, the following principles need to be followed:
1.Before use, check whether the appearance and connection of the solar electric heat trace are normal, and repair or replace it in time if it is damaged, broken, loose, etc.
2.In use, avoid the influence of mechanical damage, chemical corrosion, electromagnetic interference, etc., and increase protective measures if necessary.
3.After use, turn off the power supply device of the solar electric heat trace in time to avoid wasting electricity and damaging the product.
4.When not in use for a long time, remove the solar electric heat trace from the object to be heated, and store it properly to avoid moisture, sun, freezing, etc.
Fourth, regular maintenance of products.
In the process of using solar electric heat tracing, it needs to be regularly maintained and inspected to ensure its normal operation and extend its service life. In general, it is recommended to carry out maintenance and inspection at least once a year, as follows:
1.Clean the surface and insulation materials of the solar electric heat tracing, remove dust, oil, debris, etc., to avoid affecting the heating effect and insulation performance.
2.Check whether the connection of the solar electric heat trace is firm and intact, and repair or replace it in time if it is loose, broken, corroded, etc.
3.Check whether the temperature sensor of the solar electric heat trace is working normally, and adjust or replace it in time if there is any fault or error.
4.Check whether the leakage protector of the solar electric heat trace is working normally, and repair or replace it in time if it fails or is damaged.
5.Check whether the grounding device of the solar electric heat trace is working normally, and repair or replace it in time if the grounding is poor or disconnected.
6.Check whether the power supply device of the solar heat trace is working normally, and repair or replace it in time if the voltage is unstable or the current is too large.
Solar electric heat tracing is a kind of thermal insulation product that uses solar power generation, which can effectively solve the problem of freezing pipelines, equipment and containers in a low temperature environment, and ensure the normal progress of production and life. When selecting and using solar power heat tracing, it is important to follow the relevant standards and specifications to ensure safety and reliability.
