Molten salt pump out of the liquid pipe line should have a special support frame, its weight is absolutely not the role of the pump, otherwise it will be possible to cause the molten salt pump can’t work, the main hazard analysis is as follows:
    1 molten salt pump out of the liquid pipe to produce additional torque, may cause the pump shaft and motor shaft misalignment, causing the liquid pipe, stator deformation and stress is too large, the use of liquid pipe, the stator may be broken.
    2 because the pump is affected by the external force, the pump vertical error increases, causing vibration. Greatly reduce the service life of molten salt pump.
    Therefore, the molten salt pump out of the weight of the liquid pipe can’t be to bear, should consider the weight of the liquid pipe support and thermal expansion of the elimination method, in order to ensure the safe and reliable operation of molten salt pump
