Abstract

The invention discloses a long-shaft molten salt pump which comprises a motor frame, a bearing box, a bearing box bracket, a water outlet seat, a mounting bottom plate, a connecting pipe, a pump section and a water inlet and is characterized in that the pump section is divided into a first-stage pump section and a second-stage pump section; the first-stage pump section is arranged at the lower endof the pump shaft; the lower part of the first-stage pump section is connected with the water inlet; the secondary pump section is arranged below the mounting bottom plate; the first-stage pump section is internally provided with a group of impellers and guide blades; and the secondary pump section is internally provided with four groups of impellers and guide blades. With the structure, the existing structural form that the pump section is arranged at the lower end of the pump shaft is improved into a structural form that the secondary pump section is arranged below the mounting bottom plate, and mass distribution of the pump and a stress point of an unbalanced force are changed, so that reasonable mass distribution and unbalanced stress point are realized, and improvement on operation stability of the long-shaft molten salt pump is realized.

Description

technical field [0001] The invention relates to a molten salt pump, in particular to a long axis molten salt pump. Background technique [0002] The long-axis submerged high-temperature molten salt pump is mainly used in the fields of metallurgy, chemical industry, solar thermal power generation, and energy storage. It is characterized by a relatively long shaft and transports high-temperature media. Due to its special application occasions, the traditional high-temperature long-axis molten salt pump has problems such as too concentrated mass distribution and poor operational stability of the molten salt pump. The service life of the long shaft molten salt pump is relatively short, which increases the cost of the enterprise. [0003] After searching, the literature is based on the optimal design and test of centrifugal long-shaft pumps with unequal heads (Zhu Rongsheng et al. Optimal design and tests of centrifugal long-shaft pumps based on unequal heads [J]. Journal of Agr...
