Application of molten salt pump

    The most molten salt pump requires Solar thermal power stations use molten salt pump requirements of the most stringent of the heat transfer fluid circulation and molten salt heat storage changing set. Molten salt is usually a mixture of sodium nitrate (NaNO₃) and potassium nitrate (KNO₃). When the temperature of the molten salt at 400⁰C to 600⁰C, they in the heat retaining, hydraulic and dense seal three aspects are the pump proposed severe test. So in solar poly thermal power plant the application of the most important a pump is vertical molten salt pump.
    Due to the high temperature, so main problem is flow characteristics will be affected by the internal clearance, which would cause slip, slip depends on temperature change allowed the gap. Therefore, careful design is crucial, heat distribution mapping software to ensure good heat dissipation effect, so that deformation can be reduced to the minimum.
    Jinan Warwick Pump Co., Ltd. design engineer said: "manufacture of high temperature molten salt pump products itself, usually without any problem. The difficulty lies in how molten salt pump is mounted to the salt shaker, because the pump shaft is long, typically up to 14 to 17 meters."
