1、选择质量好点的导热油。2、导热油加热器的电加热管表面负荷要达到相关要求加热管表面负荷建议值。3、泵的流速尽量要选大些的，流速快，就能减小导热油局部温度太高的可能性。4、导热油加热器停止工作时，应先把温度降到常温状态，避免高温停机。因为在高温运行状态停机的一瞬间，发热管表面还处于高温状态，此时发热管筒内的导热油停止流动，就会导致电热管表面导热油局部温度过高，形成积碳。

1, select the good quality of heat conduction oil. 2. The surface load of the electric heating tube of the heat-conducting oil heater should meet the relevant requirements for the surface load of the heating pipe. 3, the flow velocity of the pump should be larger and faster, and the possibility of reducing the local temperature of the heat conduction oil can be reduced. 4. When the heat conduction oil heater stops working, the temperature should be reduced to the normal temperature first, so as to avoid the high temperature shutdown. Because at the moment of shutdown at high temperature, the surface of the heating tube is still at a high temperature. When the heat conduction oil in the heating tube stops flowing, it will cause the local temperature of the heat conducting oil on the electric heating tube to be too high and form carbon deposition.
