The present invention is an improvement of the patented invention “Multi-chamber and Motor Pumps for Generating Ultra-High-Pressure”, Patent Application No. CL 2006-2331 and “Multi-chamber with Motor Pumps whose chambers plus the exterior do not have motor pumps or space for their installation, until after m chambers . . . ”, Patent Application No. CL 2012-0239; which is applied to several uses in different areas: ultra-high pressure food which makes it possible to sterilize it leaving the food with better organoleptic characteristics than when it is done by temperature; cutting of metallic plates with liquid jet accelerated by ultra high hydrostatic pressure, allowing a more precise cut and not changing characteristics of the material that is fused with oxyfuel; sintering to ultra high hydrostatic pressure in which it is possible to use and make new, ultra resistant materials with the desired shape.
The prior art is given by the development which is based on the new way of achieving ultra high hydrostatic pressure through multi-chamber having ultra-high pressure motor pumps:
In the first patent application No. CL 2006-2331, there is only one chamber per motor pump and it is possible to achieve a hydrostatic pressure of 3 times or 10 times, or more, of the tensile strength of the material with which the motor pump is made. It achieves the ultra high pressure and can be used in food industry, sintering at ultra high pressure and cutting of materials with ultra high pressure.
Then, the improvement was incorporated, consisting of putting several chambers per each motor pump, because they support the pressure difference in a better way; so that it has less motor pumps than cameras, to achieve the same ultra high pressure. In this second case, for example, a pressure of 600 MPa is applied outside the multi-chamber and injected into a multi-chamber having 3 chambers at the beginning of the process without a motor pump, only to enter to a fourth chamber having the first motor pump. Then, the first motor pump generates pressure from 600 MPa to 1,000 MPa which are injected into chambers 5 and 6, and then to another motor pump that generates from 1,000 MPa to 1,400 MPa, and even further depending on the design of the multi-chamber.
This system is more efficient than the first one because it has several chambers by motor pump, it resists more than one chamber, having the wall with equal thickness that a set of concentric chambers.
The motor pumps are really simple, in essence they are two analogous pieces: one piece is a piston with a cylinder rigidly or solidly joined to another piece that is similar; so that the pistons match or fit into the cylinders of the other piece.
It does not need to be mounted on something solid because action and reaction efforts are generated between the cylinders and pistons of the motor pump itself; it is enough that they are secured with the flexible pipes. Therefore, as it is a pump or run on liquid, it can also be a gas-operated compressor, as in the present improvement we are patenting.
The present improvement has the object of making it clear that, in order to achieve ultra high hydrostatic or isostatic pressure, it can start compressing gas, for example helium, argon, etc., to achieve a pressure of eg. 3,000 MPa and then, the gas is transformed into liquid by effect of the pressure, to continue compressing the same liquid in later stages.
In more external stages, the gas is compressed, until it reaches a level of pressure and temperature in which the gas is transformed into liquid, so that the motor compressors must start to run with liquid, i.e. like motor pumps. The valves can work well either with gas or liquid so there is no problem.
But the liquid has less compressibility than a gas, so that once it is converted to liquid, the chamber in which it is located must have enough space so that the pressure does not excessively rise or fall with a pumping of the motor pump; or the motor pump must be small enough compared to the chamber, that the pressure does not rise or fall when the motor pump operates.
Although it does not contain significant changes, the multi-chamber with motor pumps or motor-compressors, it is estimated that it is a significant improvement to work with gas, because it allows to greatly facilitate the supply of heat to higher levels through electric energy.
