Determine the speed of molten salt pump, you should consider the content of the following four aspects.
     One, if the speed of the molten salt pump is higher, the volume of molten salt pump is smaller and the weight is more clear. If the naval vessels and military equipment use molten salt pump, they generally use high speed molten salt pump, which has the characteristics of high speed and small size.
    Two, speed is related to the ratio of the speed and the ratio of the speed is related to efficiency. So if you want to select the speed, you should consider the ratio of the speed.
    Three, if the speed increases, the flow is not faster than abrasion, it is easy to produce vibration and noise.
    Four, improving the speed of molten salt pump is limited by condition of the cavitation.
