摘要
A diagram and description of an ejector hydraulic reciprocating pump unit for the pumping of oil from wells, as well as a diagram and description of an experimental laboratory setup are presented. The newly designed deep-well rodless reciprocating pump differs from the usual hydraulic reciprocating pumping units by the method of putting into motion the piston group. The method of investigation and recording of the measured parameters of the unit is set forth.
