Vibration of molten salt pump mainly dues to the following reasons
    1. Molten salt pump shaft is bent or not;
     2. The gap between pump shaft and sliding bearing is too large. If vibration of pump is large, the efficiency is low;
    3 .Pump shaft is sufficient strength and rigidity or not;
    4. Equipment of pump is reasonable or not;
    5. The material selection of molten alt pump’s all parts is reasonable or not.
    If those reasons can’t solve the problem, considering the structure design of the molten salt pump is reasonable.
