Abstract

The invention discloses a small lead base reactor pump. The small lead base reactor pump comprises a motor, a motor cooling cavity and a pump shell, wherein the motor is used for driving hydraulic parts in the pump shell to rotate, and is fixed through a motor upper support and a motor lower support; the motor cooling cavity sleeves the motor, and is used for cooling heat generated during workingof the motor; the hydraulic parts are arranged in the pump shell; a hollow shaft is mounted on the motor, and penetrates through the motor upper support and the motor lower support; one end of the hollow shaft is inserted in the pump shell, and is connected with the hydraulic parts; a pump inlet is formed in the outer wall of the pump shell; and a pump outlet is formed in the bottom of the pump shell. The pump is compact in structure, reliable in operation, free of leakage and particularly suitable for conveying of high-temperature mediums; the hydraulic parts are all dipped in the high-temperature mediums; and the pump can be applied to space-limited small reactors.

Description

technical field [0001] The invention belongs to the technical field of cooling systems for lead-based reactors, and in particular relates to a pump for small lead-based reactors. Background technique [0002] As one of the fourth-generation advanced reactors, lead-based reactors mostly use vertical mechanical pumps for coolant-driven pumps. Common vertical mechanical pumps include shaft seal pumps, magnetic pumps, canned pumps, etc. [0003] When transporting high-temperature liquid metal medium in a lead-based pool reactor, the drive pump is composed of a hydraulic part, a motor part, a pump casing, a shaft seal, a coupling, and auxiliary systems such as cooling and lubrication, and requires a large installation space . In occasions with certain space constraints, in order to transport high-temperature, high-density liquid metal, it is necessary to optimize the structure of the drive pump to meet the requirements for use in lead-based pool reactors.
