Description

(54) SPRAY PUMP

one

This invention relates to inkjet technology.

The closest to the proposed technical essence and the achieved result is a jet pump, mainly for transferring viscous liquids, containing a hollow conical body with an active nozzle in the upper base and a conical vessel placed in the body, the cavity of which is connected to the branch pipe of the active medium supply and the body cavity one.

However, this jet pump has a comparatively low productivity and is not suitable for pumping viscous liquids at low temperatures.

The purpose of the invention is above the efficiency.

This goal is achieved by the fact that the pump is provided with an annular pipe with nozzles and mixing nozzles installed at the outlet of the latter, the pipeline being connected to the nozzle supplying the active medium and installed on the side of the lower base of the housing. The nozzles of the pipeline are located tangentially to the pipeline, and the vessel i

Equipped with axially movable reflector.

FIG. 1 shows a jet pump, a longitudinal section; in fig. 2 is a view A of FIG. one.

The jet pump contains a hollow conical body 1 with an active nozzle 2 in the upper base, placed in the body 1 of a conical vessel 3; the cavity of which is in communication with the nozzle 4 for supplying the active medium and the cavity of the housing 1, the displacement chamber 5 and the diffuser 6. The pump is equipped with an annular pipeline 7 with nozzles B and the mixing nozzles 9 installed at the outlet of the latter, the pipeline 7 connected to the nozzle 4 for supplying the active medium and installed from the side of the main housing base 1. The nozzles 8 of the pipeline 7 are located tangentially to the pipeline 7, and the vessel 3 is equipped with a reflector 10 that is axially movable.

The active medium, such as steam, is fed through pipe 4 into the cavity of the conical vessel 3 and from it enters the cavity of housing 1

and further into the active nozzle 2, which has expired, it carries into the chamber 5 a mixture of a passive fluid medium. From the mixing chamber 5, the mixture of media enters the diffuser 6, where the kinetic energy of the flow is partially converted into potential. A part of the active medium flows from the nozzle 4 into the pipeline 7 and from it into the nozzles 8, which has elapsed into the mixing nozzles 9 and leads to a passive medium with the formation of a rotating mixed one at the outlet. The displacement of the passive medium into the pump is achieved by moving the reflector.

Thus, by installing a pipeline with nozzles and mixing nozzles at the inlet to the housing of the jet pump, an improvement is achieved in the mode of feeding the passive medium into the pump and, consequently, increasing its efficiency.
