Abstract

The invention discloses a jet flow and blade combined pump, aiming at providing an integral pump which has the advantages of large suction range of a jet flow type pump and high stroke of a blade typepump, and also has the advantages of no need of long connecting pipes and compact structure. The invention has the technical characteristics that the jet flow type pump is composed of an input port (11), a jet nozzle (2), a choke (3) and a diffusion pipe (5); the blade type pump is composed of an impeller (6), a volute (17), an output port (10) and a motor (7); the invention combines the jet flowtype pump and blade type pump in one casing (16) in the mode of series connection, wherein the input port (11) of the jet flow type pump is the input port of the integral pump, and the output pump (10) of the blade type pump is the output port of the integral pump. The combined pump of the invention is used for household water lifting and water pressurization, and has obvious advantages.

Description

technical field [0001] The invention relates to a compound pump for conveying fluid, in particular to a compound pump combining jet pump and vane pump. The jet pump refers to a pump that uses the turbulent entrainment effect of a large Reynolds number jet without solid wall effect to transport fluid on the boundary; the vane pump refers to a pump that uses the interaction between an impeller and a fluid to transport fluid, Such as centrifugal pumps, mixed flow pumps, axial flow pumps and vortex pumps. Background technique [0002] The existing combination pump of jet pump and vane pump, such as the common combination pump used for deep well water supply, is to sink the jet pump under the water at the bottom of the well, install the centrifugal pump on the well, and connect the two with two The pipeline is connected, and the centrifugal pump installed on the well provides the working fluid to the jet pump under the well bottom through a connecting pipeline to suck the well w...
