Further set：The liquid reserve tank bottom side is provided with liquid discharging tube, is also set on the liquid reserve tank above the liquid discharging tube
There is the liquid-feeding tube connected with liquid reserve tank.
By using above-mentioned technical proposal, because the liquid in liquid reserve tank has the loss of part in use, because
This needs to supplement the amount of liquid of liquid reserve tank by liquid-feeding tube when fluid low in liquid reserve tank, while needs the feelings such as maintenance
Liquid can be discharged by liquid discharging tube during condition.
Further set：The liquid reserve tank side is additionally provided with the liquid level marking device connected with liquid reserve tank for showing liquid level.
By using above-mentioned technical proposal, for supplying the level condition inside observer's observation liquid reserve tank.
Further set：Observation panel is provided with positioned at intrusive mood pump side above the liquid reserve tank, the observation panel is provided with
Observation lid, the observation lid, which is surrounded by, will pass through the fixing bolt that observation lid is fixed on liquid reserve tank.
By using above-mentioned technical proposal, observation lid is mainly used in checking liquid reserve tank internal unit situation, while observes liquid
Body situation
In summary, the invention has the advantages that：Its overall structure is simple, and control accuracy is high, is arranged in liquid reserve tank
The heater in portion so that liquid is each filled with inside and outside heating coil, heat utilization ratio is high, while the distribution of liquid can be effectively real
Existing heating region liquid is fully moved, it is ensured that the heat of liquid-storage system is uniformly distributed.
