The oil tank electric heating tube is a new type of environmentally friendly thermal energy conversion electric heating element. The electric heating tube generates heat and the thermal energy is transmitted to the oil temperature rise. This heating method is small in size, relatively flexible in installation, and the conversion of electrical energy into thermal energy is very environmentally friendly. At the same time, high heat transfer efficiency can ensure that a higher operating temperature is obtained at a lower operating pressure. However, the problem we usually encounter is that the electric heating tube of the oil tank is easy to form coke and carbon deposit after using it for a period of time, which leads to a short service life.
So what are the precautions for using the oil tank electric heating tube?
1. The surface load of the electric heating tube of the oil tank should be designed according to the viscosity of the oil. The design with good fluidity is less than or equal to 1.5KW per meter, and the power of heavy oil is 1KW per meter.
2. When the electric heating tube of the oil tank stops working, the temperature should be reduced to normal temperature first to avoid high temperature shutdown. Because the surface of the electric heating tube of the oil tank is still at a high temperature at the moment of shutdown during high temperature operation, at this time the heat transfer oil in the oil tank stops flowing, which will cause the local temperature of the heat transfer oil on the surface of the electric heating tube of the tank to be too high, forming Carbon deposits
3. Select the appropriate protective cover according to the specific site requirements.
4. Do not dry burn (all liquid electric heating tubes must ensure that the heating area is completely immersed in liquid)
