Magnetic drive pumps are widely used in chemical industry, pharmaceutical, petroleum industry, electroplating, food processing, film photo processing, research institutions, national defense industry, etc. D. The medium inside the magnetic drive pump is organic acid, organic compound, alkali, neutral solution and so on. Because winter temperatures are low, especially in northern regions, temperatures are low in winter, and it is easy to freeze if isolation measures are not taken. The appearance of electric heating cable is a good solution to this problem. 。

Electric heating is a freeze protection measure that uses a heat-dissipating electrical tape that accompanies the laying of pipes, tanks, etc. D. To provide heat so that the environment inside the pipe can be maintained within a reasonable temperature range. The current electric heating is mainly divided into MI mineral insulated heating cables. Constant power electric heating, self-regulating electric heater, etc. Among them, the first two types of electric heating mainly use the heat generated by the current passing through the resistance. Self-temperature-controlled electric heating is mainly a flat shape extruded from the conductive plastic and the prefabricated tire, which ensures good contact with the pipeline.

For magnetic drive pumps, the self-regulating electric heating cable is usually used to keep the heat of the magnetic drive pump. In use, the electric heating cable is wound outside the pump body to the inlet and outlet. The self-control temperature electric heating cable is divided into three types: low-temperature, medium-temperature and high-temperature. As for which product to choose among the magnetically driven pumps, it depends on the model of the magnetically driven pump.

The liquid transported by the stainless steel magnetic pump is alkaline, and the liquid transported by the fluorine magnetic pump is acidic liquid When choosing explosion-proof electric heating cables for the two types of magnetic pumps, it is necessary to look at the freezing temperature and boiling temperature of the alkaline or acidic liquid itself. However, the temperature of the liquid transported by the high-temperature magnetic pump is relatively high, above 100 ° C, and the explosion-proof high-temperature self-regulating electric heating cable can be directly considered.

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.

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.

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.

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 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.
