SU440499A1 - Pump installation with devices for separation of mechanical impurities from the pumped liquid - Google Patents

Description

one

The invention relates to the field of pump construction.

A known pumping unit with a device for separating mechanical impurities from the pumped liquid contains a hydrocyclone installed on the pump suction line, the cylindrical inner part of which is provided with a helical guide, discharge pipe passing inside the cyclone along its vertical axis, and an ejector connected by nozzles to the bottom hydrocyclone cone.

The aim of the invention is the intensive separation of mechanical impurities and ensuring their subsequent transportation to the surface.

This is achieved by the fact that the ejector is made in the form of a truncated cone, which is part of the discharge pipe and connected by a smaller base to a hydro cyclone by means of nozzles.

The drawing shows the proposed pump installation.

Ola consists of a casing 1 installed above the water intake grid 2 of a submersible electric pump 3 fixed by a collar 4, a body of a hydrocyclone 5, the cylindrical inner part of which is made in the form of a helical surface 6, an ejector 7 made in the form of a truncated cone, which is

part of the discharge pipe and connected by a smaller base to a hydrocyclone 5 nozzles 8. Water with mechanical impurities comes

through the tangential entrance to the hydrocyclone 5, where the passage along the helical surface 6 rotates intensively and moves downwards. Mechanical impurities contained in water are centrifugally thrown off to the periphery and move to the lower part of the hydrocyclone, from where they are transported into the pump lifting pipe under the action of ejection, as a result of which impurities separated from the pumped liquid do not enter the pump and do not remain in the well, through a water pipe in a sump or a collection tank located on the ground.

Subject invention

A pump unit with a device for separating mechanical impurities from the pumped liquid, containing a hydrocyclone installed on the suction line of the pump, the cylindrical inner part of which is provided with a helical guide, discharge pipe passing inside the hydrocyclone along its vertical axis, and an ejector connected by nozzles to the bottom

part of the hydrocyclone cone, characterized in that, in order to intensively separate the mechanical trenders and subsequently transport them to the surface, the ejector is made in the form of a truncated cone, which is a part of the discharge pipe and connected to the hydrocyclone with a smaller base using the above-mentioned pipes.
