Question

A pump must suck a well as deep as 20 m, water temperature 25 ° C, how the arrangement puts the pump depth so that water can be pumped perfectly, count and use the required table

Answer 1

Production by bottom-hole pumps is a mechanical technique. The fluid entering the well from the formation is lifted to the surface by a pump installed below the producing fluid level. The prime mover of the pump is installed either on the surface, or in the well; in the latter case, it is integral with the pump. The bottom-hole pump unit comprises all the mechanisms and equipment serving the purposes of production. The chapter discusses the sub-divisions of the bottom-hole pumps. The sucker-rod pump is a plunger pump performing a reciprocating motion. Its prime mover is installed on the surface. ways. If a crank and a flywheel are used, the installation is called a crank-type or walking-beam-type sucker-rod pump. long-stroke hydraulic pumps, a hydraulic means of transformation is adopted; the installation is called a hydraulic sucker-rod pump. If the transformation is by wireline and pulley, the installation is called a derrick-type sucker-rod pump. In rodless bottom-hole pump installations, the bottom-hole pump may be of plunger or centrifugal or some other type. Hydraulic pumps are driven by a hydraulic engine integral with them, driven in its turn by a power fluid to which pressure is imparted by a prime mover situated on the surface. This type is called a hydraulic (rodless) bottom-hole pump. Centrifugal pumps integral with an electric motor, and lowered to the well bottom, are called submersible pumps. Further rodless bottom-hole pumps include electric membmrbe pumps and sonic pumps.
