Embodiment
In order to deepen understanding of the present utility model and understanding, below in conjunction with the drawings and specific embodiments, illustrate the utility model further.
embodiment 1:
See Fig. 1, a kind of High Temperature High Pressure pump for liquid salts seal arrangement, described seal arrangement comprises pump shaft 10, the top of described pump shaft 10 is provided with top guide bearing parts 9, the bottom of described pump shaft 10 is provided with lower guide bearing parts 5, described seal arrangement also comprises deflector 4, multi-stage impeller 3 and suction bell 1, described multi-stage impeller 3 is arranged between deflector 4 and suction bell 1, the top of described pump shaft 10 is also provided with support tube 2, sealing protecting tube 6, the both sides being arranged on pump shaft 10 of described sealing protecting tube 6 symmetry, described multi-stage impeller is fixed on pump shaft by impeller nut.This technological scheme is provided with sealing protecting tube, solves High Temperature High Pressure fused salt in prior art and makes the technical problem of shaft sealing leakage, and the high temperature that significantly can reduce conveying liquid, on the impact of bearing and seal arrangement, improves the working life of bearing and seal arrangement.
embodiment 2:
See Fig. 1, improve as one of the present utility model, described seal arrangement also comprises sealing diffluence room 7, the both sides being arranged on pump shaft 10 of described sealing diffluence room 7 symmetry.All the other structures are identical with embodiment 1 with advantage.
embodiment 3:
See Fig. 1, improve as one of the present utility model, the quantity of described support tube 8 is at least one.All the other structures are identical with embodiment 1 with advantage.
embodiment 4:
See Fig. 1, improve as one of the present utility model, the quantity of described support tube 8 is three, is arranged on uniformly around pump shaft, and three support tubes are connected with annular exit chamber simultaneously.All the other structures are identical with embodiment 1 with advantage.
embodiment 5:
