SU1206493A1 - Immersion jet pump - Google Patents

Description

{i3o6peTeHHe refers to inkjet technology, mainly to submersible jet pumps for. pumping of gassing liquids.

The aim of the invention is to simplify the operation of the pump.

The drawing shows the proposed submersible jet pump, a longitudinal section.

The pump contains a housing 1 with an active nozzle 2, a mixing chamber 3 and a diffuser 4 and a nozzle 5 for supplying a passive medium installed coaxially with the active nozzle 2 below the latter. The nozzle 5 is equipped with a float 6, and the housing 1 is conical seduye 7 and interacting with There is a spring-loaded elastic cuff 8 with an expanding element 9 installed with the possibility of axial movement.

By means of a cable suspension, the jet pump is lowered into the well. In

the time of descent under the action of the weight of the pump spring-loaded cuff 8 with the expanding element 9 is in the upper position. When the float 5 6 is immersed in a liquid due to its lifting force, the elastic cuff 8 with the expanding element 9 moves downward, and as a result of interacting with the conical seat 7, the elastic cuff 10 8 expands and fixes the jet pump in the well, the last packer. The gas released from the liquid.

SUBMERSIBLE JET PUMP, comprising a housing with an active nozzle, a mixing chamber and a diffuser, and a passive medium supply pipe installed coaxially with the active nozzle below the latter, characterized in that, for the purpose of simplifying operation, the pipe is equipped with a float and the body with a conical seat and interacting with a spring-loaded elastic cuff with an expandable element mounted with the possibility of axial movement. to SU ,,,, 1206493 1206493 .-- .. 2 the descent time under the action of the weight of the pump, the spring-loaded cuff 8 with the expansion element 9 are in the upper position. When diving the float 5 6 into the fluid due to its lifting force, the elastic cuff 8 with the expanding element 9 moves down, and as a result of interaction with the conical seat 7, the elastic cuff 10 8 expands and fixes the jet pump in the well, packing the latter. The gas released from the liquid enters the active nozzle 2 and, flowing out of the latter, carries liquid into the mixing chamber 15 3, which enters through the pipe 5 for supplying a passive medium. The mixture of media from the mixing chamber 3 enters the diffuser 4 / where the kinetic energy of the mixture 20 media is partially converted to potential, and further down the well to the surface.
