High-flow molten salt axial flow pump

The invention relates to the technical field of fused salt axial flow pumps, in particular to a large-flow fused salt axial flow pump which comprises a pump shell and a liquid pumping mechanism arranged on the pump shell and used for pumping liquid, a fixed flange plate is fixedly connected to the outer wall of the pump shell and located below a turning part, and a connecting flange is fixedly connected to the top end of the pump shell. A fixing ring is fixedly connected to the outer wall of the fixing flange plate, limiting rings are fixedly connected to the upper end and the lower end of the outer wall of the fixing ring, an adjusting block is arranged between the limiting rings, and an inwards-sunken adjusting cavity is formed in the bottom of the adjusting block. According to the molten salt axial flow pump, the sunken area can be rapidly supported, horizontal installation of the molten salt axial flow pump is guaranteed, the supporting position can be adjusted according to the sunken position by rotating
