Description

FIELD OF THE INVENTION This invention relates to inkjet technology, mainly to gas-jet pumps for pumping liquid media containing solids.

The purpose of the invention is to increase productivity.

In FIG. 1 shows a longitudinal section through a jet pump; in FIG. 2 - section aa in figure 1.

The submersible jet pump comprises a housing 1 with a mixing chamber 2, a diffuser 3 and a nozzle 4 for supplying an active medium and a nozzle 5 for supplying a passive medium with a check valve 6. mounted coaxially to the housing 1 with the formation of the last vortex ring receiving chamber 7 and an annular active nozzle 8 .

The output section 9 of the plug part of the pipe 5 for supplying the passive medium is made expandable and formed by a conical surface, the check valve 6 is installed in the output section 9 of neTpy6ka 5 for the supply of the passive medium, the pipe 4 for supplying the active medium is tangential, and the pipe 5 for supplying the passive medium is inlet a grid 10 is installed, and a mixing chamber 2 and a diffuser 3 are mounted on the housing 1 with the possibility of an axial goreme of a puppy. - -

The active gaseous medium through pipe 4 is fed into the receiving chamber 7, where it is twisted and fed into the active nozzle 8, expired from the nozzle 8, the active medium creates a zone of reduced pressure above the pipe 5 for supplying the passive medium, which causes the check valve 6 to open and through the pipe 5 of the pumped liquid medium into the pump. Expired from the passive medium supply pipe 5, the liquid medium is mixed with the active gaseous medium in the mixing chamber 2 and from the latter, the gas-liquid stream enters the diffuser 3, where the kinetic energy of the stream is partially converted to potential energy. From the diffuser 3, the gas-liquid flow through the pipeline is supplied as intended. By moving the mixing chamber with the diffuser 3 along the axis Kopnvca 1, the flow area of the active nozzle 8 and, consequently, the performance of the jet pump are controlled.

Claims (1)

The claims A submersible jet pump comprising a housing with a mixing chamber, a diffuser and a nozzle for supplying an active medium and a nozzle for supplying a passive medium with a check valve, mounted coaxially with the housing to form, with the latter, a vortex annular receiving chamber and an annular active nozzle, characterized in that, in order to increase productivity, the outlet section of the flowing part of the pipe for supplying a passive medium is made expandable and is formed by a conical surface, a check valve is installed in the outlet section of the pipe odvoda passive medium, the active medium supply manifold formed tangential inlet passive medium supply pipe is a net, and the mixing chamber with a diffuser mounted in the housing.
