The invention relates to the technical field of boiler water-feeding pump, in particular to a high-pressure boiler water-supplying pump matching with a thermal generator set, which is characterized in that a pump shaft in front of a first-stage impeller of a multi-stage impeller is provided with an inducer, and the inducer and the first-stage impeller form an inducer mechanism. The high-pressure boiler water-supplying pump has the following advantages that: the inducer mechanism solves the problem of cavitation, and by combining with dual-shell structure technology, the designed novel high-speed large-flow high-pressure boiler water-supplying pump is not provided with a fore pump and is not convenient to overhaul. Because the boiler water-feeding pump is not provided with the fore pump, the occupied space of a pump set is reduced, a system is simplified, the reliability and the safety of the system are improved, and the construction cost is reduced; and by using the dual-shell structure, water inlet and outlet pipelines, and a pump base and pump shell components are not necessary to be disconnected during overhaul so that the mounting, the debugging, the maintenance and the overhaul are convenient and quick, the overhauling time is reduced, the utilization rate of a boiler is improved, and the economic benefit of an electric power plant is increased.
