Technical Field

[0001] The utility model relates to the technical field of feed pumps, in particular to a water jet feed pump tooling. Background Art

[0002] Jet pumps have no moving parts and have the advantages of simple structure, high reliability, easy processing and maintenance. They are widely used in aerospace, electric power, petrochemical, water conservancy and other fields. When the working fluid in the jet pump is ejected at high speed, a vacuum is formed at the entrance of the throat because the surrounding air is swept away by the jet, and the transported material is sucked in, thereby realizing the transportation of the material.

[0003] When the jet pump is conveying solid materials, if the particles of the solid materials are large, it will not only cause the jet pump to be blocked, but also impact and cut the inner wall of the jet pump, causing the jet pump to be unable to use normally and reducing the service life of the jet pump. Utility Model Content
