Modelling the Modes of System of Asynchronous Centrifugal Units of Multi-Unit Pumping Station with Serial Connection of Pumps

Based on the current regulations on pipeline transport, the need for a systematic approach to the study of processes occurring in the technological complexes of pumping stations of the main pipelines and their power supply systems is shown.

Dynamic Modes of Synchronous Electric Drive with Centrifugal Hydraulic Load of Pump Station

The contemporary state of the modelling of the pump station’s electric drive in a complex with its centrifugal hydraulic load has been analysed. It was found that most studies focus either on the modelling and development of automatic control systems for the asynchronous electric drive of pumps or on the optimization of performance indicators of the station as a whole. Besides, usually only one of the subsystems of a pumping station (or an electrically-operated pump unit) is modelled with a good degree of detail: either electromagnetic or hydraulic.

Method of experimental investigation of the friction facility pneumatic wires

Aim. Development of a method for experimental study of the coefficient of friction for pneumotransport systems of gaseous media using the method of similarity and dimensionality theory, which allows expanding the number of factors and they intervals by grouping them into dimensionless similarity criteria. Method. The planned experiment was chosen for experimental studies of the coefficient of air friction. The main factors were pressure, diameter of the pipeline, air flow.

Modeling quality of underground pipelines in the conditions of corrosive fatigue

The presence of fatigue cracks on the surface of metallic underground pipelines sharpens the problem of calculation values of strength characteristics at the action of corrosive environments, that did not find the complete decision nowadays. In this connection it is needed to correct the row of defects and normative and technical documents related to insufficient actuality of corresponding.

Modeling of Hydraulic Load of Electric Drive in Electrical Complex of Pumping Station

The paper analyses the contemporary state of the electric drive hydraulic load modelling in the pumping stations’ electrotechnical complex applications. It was found that in the vast majority of cases, mathematical models do not allow taking into account the specificities of fluid pumping and its consumption at the same time with a balanced degree of detail.
