Resumen
[0001] High pressure hydraulic pump system without external energy requirements and procedure for putting said system into practice. [0002] The system is designed as a hydraulic pump, for water or another incompressible fluid at a high pressure and without any external energy requirements, based on a positive displacement hydraulic machine and formed by, at least, two parallel columns of vertical load fed from an upper tank (6) of fluid, so that said parallel columns end in respective sets of two actuator cylinders with pistons, with two actuator cylinders (1) and (2) being connected at the base thereof by means of a transversal pipe (5) and comprising discharge pipes at the heads thereof with charge and discharge valves (10-10') and (11-11'), together with two suction-impulsion work cylinders (3) and (4) for bringing the fluid to be pumped from a lower tank (7), through pipes (12) and (13) with non-return valves (15-16-17-18), with the actuator cylinders (1) and (2) and the work cylinders (3) and (4) being connected together by means of a rod shared by the corresponding pistons (1'-2') and (3'-4') respectively.

1. High pressure hydraulic pump system without external energy requirements, for pumping out an incompressible fluid, such as water, from a reservoir or tank, for uses that require high volumes of fluid, using as sole energy source the potential energy of an incompressible fluid, such as water, or a compressible fluid, such as pressurised gas or vapour, contained in a reservoir or tank (6) located at an upper level, and that by making use of the pressure forces exerted by the fluid of the upper reservoir or tank, is characterised in that the fluid feeds two parallel columns of vertical load pipes (8) and (9) that end in respective actuator cylinders (1) and (2) with an S1 section, and which are connected at the bases thereof by means of a transversal connecting pipe (5) and which comprise on the heads thereof a discharge pipe (8'-9') of the upper fluid, each of these cylinders being provided with an inner piston actuated by a swaying longitudinal movement, the rod of which is coaxial with the rod of the inner piston of the respective work cylinders (3) and (4) with an S2 section, that are located under the other pistons, which comprise tapered bases with two pipes (13) and (12) including non-return valves, ones that are suction valves (12) and (13) for taking up the incompressible fluid from the lower reservoir or tank (7) and other outage or discharge valves (19) for using this fluid for other uses, where the section of the actuator cylinders (1) and (2) is smaller than the section of the work cylinders (3) and (4), S1 < S2, while the dimensions of the actuator cylinders (1) and (2) and the work cylinders (3) and (4) are such that the corresponding pistons exert the same force on both of them, according to the following pressures-sections ratio: P1 x S2 = P2 x S2 = Constant value, having taken into account that in the initial stage of the system, the volume occupied by the actuator cylinders (1) and (2), plus the connecting pipe (5) is filled with a hydraulic liquid, while one of the work cylinders is filled with the incompressible liquid to be pumped. 2. High pressure hydraulic pump system without external energy requirements, according to claim 1, characterised in that it includes two main valves (10) and (11) that allow the fluid to pass through to the actuator cylinders (1) and (2), which are located in the vertical load pipes (8) and (9), and two auxiliary discharge valves (10') and (11') on the circuit of actuator cylinders (1) and (2), which are located between these cylinders and the main loading valves (10) and (11), and four non-return valves, two of which (15) and (17) are located in the suction pipes for obtaining the fluid from the lower reservoir (7) by means of the work cylinders (3) and (4), in order to prevent it from returning to said lower reservoir (7), and two other non-return valves (16) and (18) that are located in the outage or discharge pipes for sending the fluid to the outer network, in order to prevent it from returning to the work cylinders (3) and (4). 3. Procedure for putting into practice the pumping system,, characterised in that , starting from an initial stage in which one of the work cylinders, such as cylinder (3), is filled with the incompressible liquid to be pumped, the cyclical impulsion-suction process of pumping the fluid from the lower tank (6) to the outage or discharge pipe is carried out according to the following stages of synchronised operation by means of the control valves: - opening the main valve (10) keeping the main valve (11) closed and the auxiliary discharge valve (11') open, with the subsequent discharge of the fluid from the upper reservoir through the vertical pipe (8) in order to fill the actuator cylinder (1) and simultaneously emptying the lower work cylinder (3) through the action of the piston thereof by means of the non-return valve (16) through the outage pipe (19), transferring the load fluid of the actuator cylinder (1) to the actuator cylinder (2) through the transversal connecting pipe (5), and simultaneously filling the lower work cylinder (4) through the pipe (12) and the non-return valve (17) with fluid from the lower reservoir thanks to the depression created in this cylinder due to the ascent of the piston connected to the upper actuator cylinder (2), that discharges the fluid of the upper tank by means of the auxiliary valve (11') through the discharge pipe (8-9') to the lower reservoir; - closing the main valve (10) and opening the main valve (11) and the auxiliary discharge valve (10'), with the subsequent discharge of the fluid from the upper reservoir through the vertical pipe (9) in order to fill the actuator cylinder (2) and simultaneously emptying the lower work cylinder (4) through the action of the piston thereof by means of the non-return valve (18) through the outage pipe (19), transferring the load fluid of the actuator cylinder (2) to the actuator cylinder (1) through the transversal connecting pipe (5), and simultaneously filling the lower work cylinder (3) through the pipe (13) and the non-return valve (15) with fluid from the lower reservoir thanks to the depression created in this cylinder due to the ascent of the piston connected to the upper actuator cylinder (1), that discharges the fluid of the upper tank by means of the auxiliary valve (10') through the discharge pipe (8-9') to the lower reservoir or tank (7).
