METHOD OF TRANSPORTING LIQUID AND HEAD MACHINE FOR EXECUTINGSAID METHOD

摘要

Energy exchanges between fluids are produced in a system of vessels containing a pressure transmission piston (12) and cylinders (11) sealed from the atmosphere, in a succession of cycles in which liquid to be moved and pressurised operating liquid are alternately fed to individual chambers above and below the piston (12) respectively. In order to make up for the energy losses incurred in the course of the liquid transporting process in a mine cooling system, forces are applied via an actuating device (12') to the pressure transmission piston (12). To render this possible the actuating devices (12') of the particular cylinders (11) are interconnected by a common drive system (13), preferably composed of a crankshaft (17), a transmission gear (16) and an electric motor (19).
