The disclosed high temp. salt liquid pump of the utility model comprises the pump housing, pump shaft, power source and liquid-discharging tube; The described pump housing has high temperature saline solution entrance and the outlet of high temperature saline solution, and the entrance of described liquid-discharging tube is communicated to the outlet of high temperature saline solution; Described pump shaft arranges along the vertical direction, and the pump shaft bottom is connected with lower bearing, and the pump shaft lower end passes pump housing shell and be connected in the pump housing, and pump shaft top is in transmission connection to power source; The described pump housing, pump shaft, lower bearing and liquid-discharging tube are high temperature resistant material, and described lower bearing is Nonlubricated bearing; The spacing of described pump housing shell and pump shaft sidewall is less than being provided with resistant to elevated temperatures Sealing between 0.2mm or described pump housing shell and the pump shaft sidewall, and the spacing between described Sealing and pump housing shell and the pump shaft sidewall is all less than 0.2mm.
Wherein, the pump housing is used for providing pressure, drives the high temp. salt liquid movement in the tempering pond.Its general configuration is identical with the existing conventional pump, for example comprises centrifugal impeller etc.Because the disclosed high temp. salt liquid pump of the utility model is used for pumping high temperature saline solution, so its each parts are high temperature resistant material, are preferably refractory metal, more preferably stainless steel.For example corrosion-resistant and resistant to elevated temperatures SUS304 or 316L stainless steel.
Various pump of the prior art, its inside has been used various rubber or plastic seal usually, is used for reaching certain sealing effect, realizes good pump-conveying property.Usually the high-temperature resistant of plastic, rubber Sealing is 250 ℃, and in the utility model, working environment is hot environment (being higher than 400 ℃), and at this moment, above-mentioned Sealing all can't normally use.In the utility model, high temperature resistant being defined as down can proper functioning at 400 ℃.
Yet for guaranteeing the disclosed high temp. salt liquid pump energy of the utility model proper functioning, it must have certain sealability.The utility model carries out suitable transformation to satisfy above-mentioned usage requirement to the structure of the pump housing, for example, pump body structure is transformed, and passes the position of pump housing shell at pump shaft, and the spacing of described pump housing shell and pump shaft sidewall is less than 0.2mm.Perhaps be provided with resistant to elevated temperatures Sealing between described pump housing shell and the pump shaft sidewall, the spacing between described Sealing and pump housing shell and the pump shaft sidewall is all less than 0.2mm.
Though when adopting said structure, sealability has to a certain degree and descends during pump housing work,, the inventor finds, adopts the structure of the disclosed high temp. salt liquid pump of the utility model, the spacing of pump housing shell and pump shaft sidewall is less than 0.2mm; Perhaps be provided with resistant to elevated temperatures Sealing between described pump housing shell and the pump shaft sidewall, the spacing between described Sealing and pump housing shell and the pump shaft sidewall is all less than 0.2mm., when the high temperature saline solution is carried out pumping, still can normally use, and, got back in the tempering pond by the high temperature saline solution of revealing in the pump housing, can continue to be discharged by pump housing pumping.For above-mentioned Sealing, can adopt various resistant to elevated temperatures materials, for example refractory metal or pottery are preferably resistant to elevated temperatures stainless steel.
According to the utility model, as existing various pumps, have the outlet of high temperature saline solution entrance and high temperature saline solution on the above-mentioned pump housing, be respectively applied to suck the high temperature saline solution and pump out the high temperature saline solution.Concrete, the outlet of high temperature saline solution is connected with the entrance of liquid-discharging tube.The liquid-discharging tube outlet can be free end, and the high temperature saline solution that is used for pumping is come out is guided to the location.Usually, adopt high temperature saline solution turnover barreled to carry the high temperature saline solution that pumps, high temperature saline solution turnover bucket is positioned on the dolly, adopts dolly to move.
In the said structure, the entrance of described liquid-discharging tube and the welding of high temperature saline solution exit seal., installation mobile for the ease of dismantling, under the preferable case, the spacing between the entrance of described liquid-discharging tube and the outlet of high temperature saline solution is less than 0.2mm.
The disclosed high temp. salt liquid pump of the utility model in use, high temperature saline solution outlet need be in the high temperature saline solution with the entrance of liquid-discharging tube.
In the utility model, in theory, spacing between spacing between spacing between Sealing and pump housing shell and the pump shaft sidewall or pump housing shell and the pump shaft sidewall and the entrance of liquid-discharging tube and the outlet of high temperature saline solution is the smaller the better, but, consider in conjunction with processing technology difficulty and using effect, under the preferable case, above-mentioned spacing is 0.02-0.2mm.
Above-mentioned liquid-discharging tube directly contacts with the high temperature saline solution, and same, liquid-discharging tube is high temperature resistant material, is preferably refractory metal, more preferably stainless steel, for example corrosion-resistant and resistant to elevated temperatures SUS304 or 316L stainless steel.
