LIQUID MEDIA FROM THE WELL TRANSPORTATION SYSTEM AND THE SINGLE SCREW PUMP IN THE WELL INSTALLATION METHOD

摘要

FIELD: soil or rock drilling; mining.;SUBSTANCE: group of inventions relates to the liquid media transportation system from the well and to the single-screw pump in the well installation method. System comprises injection pipeline, which extends in the well longitudinal direction, located in the pipeline pumping device with the stator, rotor and connected to the rotor power transmission for the rotor eccentric movement, as well as adapter assembly (5), which is connected to the stator and, by means of the clamping contact with the pipeline, immovably holds the stator in the pipeline. Assembly (5) comprises partial area (10) with the enlarged cross-sectional diameter and at least one resilient member (15), which with the clamp are brought into contact with the pipeline and / or with located in the pipeline mounting clutch.;EFFECT: group of inventions is aimed at provision of the pumping device replacement without replacement of the pressure pipeline original piping.;19 cl, 17 dwg
