Abstract

The invention belongs to the related field of pump experimental devices, and discloses a four-quadrant characteristic test bench of a solid-liquid two-phase flow pump. It consists of a water circulation system, a working condition control system, a solid-liquid two-phase flow circulation system and a high-speed photographic acquisition system. As a solid-liquid two-phase flow pump, the deep-sea mining pump should be considered during operation. Therefore, it is necessary to carry out experimental research on the four-quadrant characteristics of solid-liquid two-phase flow in the pump. The test bench of the invention can realize the synchronous test of the four-quadrant characteristics of the solid-liquid two-phase flow pump and the visualization of the internal flow, and has the advantages of simple structure, complete test functions and the like.

Description

technical field [0001] The invention belongs to the related field of pump experimental devices, and provides a four-quadrant characteristic test bench of a solid-liquid two-phase flow pump. Background technique [0002] As a strategic resource for the development of high-tech, deep-sea mineral resources are of great significance to ease the supply pressure of my country's mineral resources and increase the level of my country's strategic resource security. In view of the technical characteristics of deep-sea mineral resource development, various development systems have been proposed at home and abroad, but the deep-sea ore resource development system with the most industrial mining prospects is currently recognized as the hydraulic lifting mining system, which uses seabed mining trucks to collect ores , and then use the ore pump to lift the ore to the surface mining vessel through the pipeline. The ore pump provides power for the entire conveying system and is one of the k...
