Fouling treatment of tube heat exchanger and its application in lubrication station of rolling mill

Fouling treatment on tubular heat exchanger equipment:
It is helpful for the future work to know the treatment method of fouling in tube heat exchanger. If you want to be simple, you must pay attention to the way of adding chemicals to soften, which can also effectively deal with. Moreover, according to the degree of dirt in the tube heat exchanger equipment, you can choose different ways of adding chemicals to achieve different cleaning effects.
As for the treatment of fouling on tubular heat exchanger equipment, it is necessary to pay attention to the magnetic fouling treatment that must be realized by using water molecules. In this process, high-intensity magnetic field and induced current are also involved. After treatment, it is difficult for water to form scale on the heating surface of heat exchanger. With the continuous progress of technology, there has been a relatively new type of ion anti scaling water treatment, this way of application in heat exchanger equipment has been widely recognized, because it can get satisfactory significant effect.
Application of tube heat exchanger in lubrication station of rolling mill
In fact, the rolling mills used by many manufacturers are two horizontal rolling mills. The lubrication points of the thin oil lubrication station are gears and bearing shells in the gear box of the main engine. Due to the large wear force on the tooth surface, the heat is generated, and the temperature of the lubricating oil rises to 60 ℃.
After that, the bearing bush alloy will be easily burnt out and the journal will be worn. In order to protect the equipment, almost every production shift has to stop for nearly 2 hours to cool down, which affects the production and increases various consumption. Therefore, we decided to improve the lubrication system. The cooler of the original thin oil lubrication station is a tube heat exchanger, so the heat dissipation is not good.
Generally, only one of the two oil tanks works, and the other is standby. The tubular heat exchanger is installed on the oil outlet Road, with large flow but poor cooling effect. After improvement, the oil temperature of the main oil tank is always kept at 48-50 degrees. On the one hand, the shutdown caused by high oil temperature is eliminated to a certain extent, and more than 70 tons of steel are produced per shift.
