Cavitation of high temperature molten salt pump

    One, cavitation phenomenon of high temperature molten salt pump
    Cavitation phenomenon of the high temperature molten salt pump refers to that the liquid of being delivered is partial vaporization. Partial vaporization appears because in the delivery temperature of the saturation vapor pressure is equal to or lower than the pump at the entrance (the actual pressure at the entrance to the blade) and partial vaporization, causing the pump to generate noise and vibration, serious, pump flow, pressure head and efficiency decreased significantly, obviously, cavitation phenomenon is the normal operation of the high temperature molten salt pump are not allowed to happen. Avoid cavitation of the key is the pump mounting height should correctly, especially when the temperature is higher in the volatile liquid transport, more attention should be paid to.
    Two, high temperature molten salt pump installation height Hg
    Allow suction on the vacuum height Hs is the pump at the entrance to the pressure P₁ can be allowed to reach the maximum degree of vacuum
And actual allows the ceiling on the high vacuum Hsvalue and not according to calculated values, but by Warwick pump experimental determination of the value, the value in high temperature molten salt pump samples for users to search the. Should pay attention to the value given in high temperature molten salt pump samples of Hs is with water as the working medium, the operating conditions for 20⁰ C and pressure of 101.3 x 105Pa value when operating conditions and the working medium not at the same time, the need for conversion.
    (1) if the operating conditions and the experimental conditions are different, the operating conditions and the experimental conditions are different, they can be converted to the high temperature molten salt pump.
    Hs₁ = Hs + (Ha - 10.33) - (Hu - 0.24 V)
    (2) conveying the other liquid when the liquid and conditions are transported and the conditions are not at the same time, the need for two steps: the first step in accordance with the pump will be found in the sample Hs1; second step according to the Hs1 will be converted into H s?
    2 high temperature molten salt pump NPSH delta  H
    From a safety point of view, the actual installation height of the pump should be less than the calculated value, and when the calculation of the Hg is negative, it shows that the suction port of the pump should be under the tank surface.
