Abstract

The invention discloses a vertical pump for a pool type reactor. The vertical pump for the pool type reactor comprises a pump shaft, a vertical pump shell, a hydraulic component, a power input component and a circulation component. The pump shaft is arranged in the vertical pump shell. The upper end of the pump shaft extends out of the vertical pump shell to be connected with the power input component. The lower end of the pump shaft extends out of the vertical pump shell to be connected with the hydraulic component. The circulation component is arranged on the portion, in liquid, of the pump shaft and used for generating upward or downward flowing power when the pump shaft rotates. The portion, corresponding to the circulation component, of the vertical pump shell is provided with two or more communicating holes. At least two of the communicating holes are located at different heights. The vertical pump is mainly applied to the pool type reactor and used as a main circulation pump for driving coolant, and the vertical pump for the pool type reactor can provide a enough pressure head; and besides, because the circulation component is installed on the pump shaft, the coolant in the pump shell can communicate with coolant in a reactor pool, and the coolant in the pump shell is protected against a flowing dead zone.

Description

technical field [0001] The invention relates to a vertical pump for a pool reactor. The circulating main pump can be used in pool-type sodium-cooled reactors, pool-type lead-based reactors and other pool-type reactors as a driving device for the circulation of coolant in the main loop. Background technique [0002] Among the fourth-generation advanced reactors, both sodium-cooled reactors and lead-based reactors are pool reactors. Coolant circulation in pool reactors requires pumps to provide driving force. The medium conveyed by the main pump of the pool reactor is liquid metal such as liquid sodium, lead and lead alloy. Due to its relatively mature structure and process and high reliability, mechanical pumps have a very wide range of applications, and can also be used in pool reactors. [0003] In the liquid metal cooled pool reactor, the primary circuit is a pool cycle, nuclear fuel, main pump, main heat exchanger and other key equipment are placed in the main container...
