Rate is exported, to realize heat tracing purpose.Electric tracing is compared with steam (hot water), reliability height, No leakage, saving water resource, still
Resistance-type electric tracing carries the limitation using length, if it exceeds certain length is, it is necessary to increase more supply terminals.Therefore, when
By the process pipelines length of heat tracing it is longer when, matched supply terminals quantity also can accordingly increase, and not only cost is high, and therefore
Barrier hidden danger point is more, maintenance difficulties increase

It is long, can be rapidly and efficiently liquid-transport pipe-line 11 is heated.
The principle to kelvin effect (being referred to as Kelvin effect) is simply introduced below：
1st, when applying alternating voltage to conductor, electric current flows through from its outer surface, and to be no electric current flow through at its center.
If the 2, conductor center is considered as hollow, and alternating voltage is applied to inside pipe wall surface, then its outer surface is no electric current stream
Cross.
First, by the system of the embodiment of the present invention, the liquid that liquid-transport pipe-line 11 is exported can effectively be kept default
Temperature, such as preset temperature be 50 DEG C, then detect liquid-transport pipe-line 11 output liquid be not up to the temperature when (as only be 45
DEG C), effectively the liquid in liquid-transport pipe-line 11 can be heated, the process is heat tracing；And by liquid-transport pipe-line 11
The liquid of condensation is heated to preset temperature, or the cryogenic temperature (such as 0 DEG C) in liquid-transport pipe-line 11 is adjusted into 50 DEG C default
The mode of temperature, the process is heating.Therefore " heating system of the intelligent transfusion pipeline of liquid-transport pipe-line 11 " of the present invention can
Think " heating/tracing system of intelligent transfusion pipeline 11 ".
