Operating conditions for agricultural and large water bodies of waterworks vary widely, most are away from urban development, located in mountainous terrain, wooded terrain, with insufficient transport and energy support, and the scale of design and capital investment is limited. Manual icing and heat preservation methods have high labor intensity and low efficiency, are highly dependent on human factors, and do not meet the requirements of production safety and automation. Water jet and air blowing methods require a large initial investment in equipment and high energy costs, and are mainly used to control icing before the closures of large and medium-sized reservoirs, which does not meet the conditions and applications for the protection of agricultural water resources.
Electric heating has little effect on the operation of the lock, does not threaten the safety of the lock and waterworks, the technical solution is easy to implement, it can be operated in dry channel conditions, which can meet the need to prevent and control the dangers of freezing and icing. Its operating principle is to equip the power supply with appropriate power according to the ambient temperature and structural size of the sluice, and to install the heating element on the back-face seal joint of the sluice water to prevent the sluice sealing device and the sluice from freezing. The heat generated by the heating element is transferred to the environment through the metal sluice structure, and a warm water zone is maintained around the sluice body, allowing normal opening and closing of the sluice.
Electric heating cables are increasingly used in gateway construction, mainly divided into self-regulating temperature heating cables and constant power parallel heating cables. Electric heating cable in series, the working voltage is usually 220 or 380 V AC. Under normal conditions, self-limiting temperature electric heating cables are mainly used on the equipment platform. Its characteristic is that it can change the calorific value of the heating cable when the ambient temperature changes. It can change the calorific value of the heating cable. Heating cable with ambient temperature change and has the ability of self-monitoring temperature change compensation.

Electrical heating installation precautions
Electric heating cable is a heating method that uses insulation resistance or resistance heating wire to create a temperature after power supply. It can automatically adjust the output temperature and reasonably maintain the process temperature requirements to keep warm, raise the temperature and protect the heating equipment from freezing. The insulation and antifreeze effect of the container is very good.
Which electric heating should be chosen for the main pipeline transport of heavy oil
Transport of heavy oil through the pipeline over long distances and long-term retention in the pipeline will result in a drop in temperature due to heat dissipation and increased viscosity, which will cause the pipeline to be blocked by freezing or condensation-related accidents. Electric heating is widely used as effective insulation of pipelines and anti-freeze protection.
Which electric heating cable should be considered for a 4 km pipeline
According to the statistics of the Hydrometeorological Center, the average daily minimum temperature at the location of the CNPC tank farm is 5 ° C, and the average daily maximum temperature is 14 ° C. Since the freezing point of the PX is about 15 °C, the supply pipeline needs heat preservation and heating. The oil depot has been in operation for many years without a stable source of steam, therefore, this project is considering the use of electric heating technology.
Application of outdoor electric heating cable in oil main pipelines with high paraffin content
Long-distance crude oil pipelines with a high paraffin content with freezing temperatures above 50 °C. According to the requirements of the production plan of the plant, the volume of oil transportation through the pipeline is 150 thousand rubles. Tons per year, maximum-200 thousand. Tons per year.. According to the thermodynamic analysis of the pipeline, the initial supply temperature of the pipeline is 80 ° C (TN), and the temperature of the end entering the tank is 60 ° C (Tu). Since the transportation temperature needs to be adjusted according to the time of year, it sometimes needs to be transported by heat.
What heating product to choose for main infusion pipelines
In petrochemical engineering, trunk infusion pipelines are the lifeblood of the factories. The temperature in the northern region is too low in winter and the pipeline needs to be insulated to compensate for the heat loss due to the low temperature in winter to ensure the normal operation of the pipeline.
The role of leather tracer cables in the insulation of asphalt main pipelines
The toughness of the asphalt is greatly affected by the temperature. When the temperature decreases, the toughness of the asphalt increases, and the drop in resistance of the asphalt during pipeline transportation increases; when the temperature falls below the freezing point, the asphalt solidifies, causing the pipeline to clog and the conveyor belt to come to trouble. Therefore, electric heating and heat preservation during the transportation of asphalt are very important.
