Description

Brochure is related to the crpviiHoi i technique, mainly to jet lumens for transferring HPLCL media.

The goal of IMPLEMENTATION is to increase productivity.

In Figure 1, a schematic of an ecchi presents the proposed jet pump, longitudinal section; figure 2 is a view of a nor figure 1; on fig.Z - section BB in figure 1; FIG. 4 is a section on BB in FIG. one .

Jet pump) includes a housing 1 with a working chamber 2, nozzles 3 and 4 supplying active and passive media, radial tubes 5 dispersed in working chamber 2 for supplying active media, ejector heads 6 installed at their outlet, tangentially directed around the circumference in one direction, and pressure pipe 7. The pump additionally contains an inlet pipe at the inlet of the pressure pipe 7, the jet device 8, the building 1 is equipped with a receiving chamber 9, and the nozzle 4 for supplying the passive medium is located in it with radial tubes 10 with nozzles 11, located coaxially with the latter or tangentially with orientation to the side opposite to the direction of the ejector nozzles 6, and supply tubes 12, located coaxially with the radial tubes 5 for the substrate of the active medium and communicated with the input of the ejector nozzles 6, the latter being installed axial movement relative to the lead tubes 12, the working and receiving chambers 2 and 9 communicate respectively with the active nozzle 13 and the mixing chamber 14 of the jet apparatus 8, and the nozzles 3 and 4 supplying the active and passive medium pa 1P 1 are coaxial with each other and are installed jointly by radial tubes 5 for supplying the active medium and inlet tubes 5 and 12c with the possibility of free rotation.

The pump works as follows. Active gaseous medium through the nozzle 3 for supplying the active medium

enters the radial tubes S for supplying the active medium and, having flowed out from the ejector nozzles fS, causes the rotation of the nozzles 3 and 4 supplying the active 5 oi medium together with the radial tubes S for supplying the active medium; 1Ы, along the tubes and the radial tubes 10 with nozzle nozzles 11. At the same time in the pipe

 About 4 supply of the passive medium creates a vacuum, which causes the flow of passive liquid medium into the jet pump. From the pipe 4 for supplying a passive medium, the latter enters into

 5 radial tubes 10 and into the supply tubes 12. From the inlet tubes 12, the passive medium enters the ejector nozzles 6 and then, together with the active medium, the passive medium flows into the working chamber 2, causing there a vortex flow around the perimeter of the working chamber 1 while removing the gaseous medium from the rotating stream. From the radial tubes 10 a passive medium, through nozzle nozzles VI, flows into the receiving chamber 9, causing a vortex movement of the passive medium around the perimeter of the latter in the direction opposite to the vortex movement of the medium in the working chamber 2. From the working chamber 2 the flow of liquid medium enters the active nozzle 13 of the jet The apparatus 8 and, having flowed out of it, draws, in a measure of mixing 14, the liquid medium coming from the receiving chamber 9. The mixture of media from the displacement chamber 14 enters the discharge pipe 7 and further to the consumer. Outflow of the passive medium from the nozzle nozzles 1 1

radially or in the opposite direction to the outflow of the er-. dosing from injectors, prevents an excessive increase in the number

 turns of nozzles 3 and 4 for supplying active and passive media with tubes 5, 10 and 12, intensifies the vortex motion of media in the working and receiving chambers 2 and 9 and regulates the flow

the penetration of the passive medium into the ejector nozzles 6. Thus, due to this design of the jet pump, its productivity is increased.
