FIELD: machine building.
SUBSTANCE: invention relates to medium transfer system. System has at least two working machines (2a, 2b, 2c), each of which has at least one bearing shaft with transporting elements arranged on it for transfer medium, and at least one drive (3a, 3b, 3c), which leads corresponding bearing shaft. Plurality of machines (2a, 2b, 2c) are connected in series so that medium is transferred into machine (2a, 2b, 2c) arranged further downstream and so that each of machines (2a, 2b, 2c) is assigned separate drive (3a, 3b, 3c). Actuators (3a, 3b, 3c) are connected in parallel to each other and to common power supply system. Drive (3a, 3b, 3c) is made in the form of hydraulic motor. Common power supply system is made in form of hydraulic power supply system.
EFFECT: invention is aimed at increasing overall throughput capacity at medium transfer and delivery pressure, while providing compact design of system with simple adjustment of transfer characteristics of multiphase mixture with compressible and incompressible medium.
