Definitions
- the invention relates to a thermohydraulic pressure increasing method and its use. Such a technical solution is needed primarily in the field of energy, mechanical engineering and chemical plant construction.
- the pressure increase according to the prior art takes over a hydraulic pump, which is driven by a motor.
- FIG. 6 (8) opens only when the internal pressure rises above the hydraulic pressure. Then hydraulic oil flows into the high-pressure container (11) and can be used for work (12). After the pressure valve (8) has opened, the further heating of the working fluid isobar (upper hydraulic pressure), until the lower reversal point in the double cylinder (5) is reached (small density). As it cools, it shrinks Volume again, the pressure drops and the low pressure of the hydraulic system (13) pushes the piston back to the upper starting position. Since the heating or cooling of the working fluid is constantly increasing or decreasing, a large part of the heat can be regenerated.
- Figures 2 and 3 show an application, such as 12 thermohydraulic cylinders are interconnected. In this case, 5 thermohydraulic cylinders are connected for regeneration in one cycle, one is heated and one cooled. With the next cycle, the connection assignment is changed by means of control, so that a complete stroke can be sucked in and pushed per cycle.
