Thermohydraulic METHOD OF INCREASING PRESSURE DIFFERENT working fluid AND ITS APPLICATION

摘要

FIELD: machine building.SUBSTANCE: in order to achieve pressure rise, hydraulic system includes hydraulic pump that is driven with electric motor that uneconomically requires high-quality types of energy, such as electric energy, diesel fuel or petroleum. If system pressure and temperature, which are specific for certain material, can be adjusted for hydraulic process, waste heat can be used for operation with volume change. Working fluid medium and oil for hydraulic systems is separated in double cylinder with piston (10). Oil (6) for hydraulic systems is arranged in lower part of double cylinder (5). Working fluid medium is arranged in upper part of double cylinder (5). By means of working fluid medium cooling phase, piston (10) is offset back to initial position by reducing volume and low pressure of hydraulic system, and process is started anew in that position. Assembly containing heat exchanger (3) and double cylinder (5) is fully isolated. Proposed method is realised in several cycles with regeneration.EFFECT: achieving the operation of devices by means of waste heat in thermal process and use of the above operation in hydraulic process for driving presses or generators in stationary industrial systems.2 cl, 3 dwg
