The principle of induction pump without moving parts and sealing offers pump's
design which efficiency is nearly 82%, which are high above all ordinary pumps.
The way of liquid propulsion especially suitable for watercrafts propulsion and for pump designing is explained in the text below. This kind of propulsion is especially suitable for submarines. The advantage on classic MHD generators is absence of contacts at all. These contacts are usually affected by electrochemical corrosions which limit operational time of the ordinary MDH pump or submarine propulsion device significantly. This kind of propulsion without contacts offers practically infinite operational time completely without the maintenance and absence of sealing enables submarine to submerge much deeper. Nuclear submarine supplied with the kind of propulsion would be able to stay submerged as much as they are energy in its nuclear reactor.
The advantage of the pump is its ability to work as asynchronous generator too, and in the case it can be used for increase of existing hydro power plans for quarter (25%) without any investment in dam or expansion of accumulation lake. In these days when the climate become wormer and precipitation decreases this is good way to extend usage of existing hydro power plants, which are only duly ecological sources of electric energy in used today.
The induction pump is also suitable for pumping of extremely hot liquid metals, corrosive liquids like melted salt and various acids.
INDUCTION PUMP WITHOUT SEALING AND MOVING PARTS
The device we know as a pump is consisted from motor and pump. Motor is usually AC electromotor
and pump is usually centrifugal pump.
Problem with pumps are in their sealing elements, especially ones that should work only occasionally, like emergency pumps in boats and ships. So, the goal is to design pump without sealing at all, and the best concept is pump without moving part, except the fluid that should remain as only motional element.
As the pump also contains electric motor the best solution is to merge the pump and the motor in the same device. Rotating magnetic field has brushless interaction with rotor in an asynchronous (AC) electromotor propelling it.
The rotor could be replaced with winded plastic pipe and in the case rotating magnetic field is able to catch conductive liquid and to propel it creating flow.
The pump with such design requires only good frequency regulator able to softly vary amplitude and frequency of three phase driving voltage.
The basic design of the pump is shown on the following picture:
PRINCIPLE OF OPEARTION
Blue is pipe is main pump's pips in which rotating magnetic field creates flow. Input (4) and output (5) should be attached on the same way as ordinary pump. Variable three phase driving potential should led wires (1), (2) and (3) respectively. Optional leads (6) should be used for additional excitation like it is used in AC motors with wounded rotors. These leads could be used for flow measuring also.
ESSENCE OF THE OPERATION
There is one very useful effect that is utilized in electromagnetic brakes: when conductive
ring rotates above the bar magnet, then there occurs mechanical interaction between the bar magnet and the disk
which tries to equalize speed of the magnet and of the ring. The force of braking is trimmed by the distance
between the bar magnet and the disk – with decrease of distance increases braking force.
The following figure depicts the basic form of electromagnetic brake:
This kind of brake was invented few years before Tesla's invention of rotating magnetic field. Blueprint of the basic design of the brake is shown on the following picture:
This concept could be further expanded with the ring's replacement with the pipe filled with conductive fluid:
In this case the same interaction that occurs between the bar magnet and the conductive ring will also occur between conductive liquid and the bar magnet. Further step is quite intuitive and plausible: the bar magnet should be replaced by three electromagnets on the same way as it is done in the case of AC motor:
Circular variant is just a representation of inductive asynchronous AC motor as aforesaid and it is shown on the following figure:
Linear pump is a variant of circular pump with rotating magnetic field in which the magnetic field is linearly shifting across
the non conductive and non magnetic pipe with conductive liquid. Non-conductive liquids must be firstly polarized with appropriate electromagnetic
Shifting magnetic field is especially suitable for pumping of liquid metals like mercury, melted salt sodium-chloride in solar power plants, or very corrosive electrolytes. It is consisted of series of electromagnet triplets in which each electromagnet is driven by one of three phase load, and then the shifting magnetic field is carrying the liquid with itself. When the liquid is replaced with conductive rod, then it is able to be made very accurate servo-mechanism.
The linear variant of the pump:
THE RAILWAY APPLICATION
The variant of maglev locomotive free of superconductors can be easily derived from the linear type of the pump. The difference between this novel maglev concept and official maglev trains is that this concept utilizes fully passive tracks making it 100 times more cheaply then official maglev ones. Usually the cost of this railroad is just a couple of percents of the price of the regular active maglev railroad!
One aspect of the magnet could be used for the robust stability which would make this trains much safer than anyone is today.
The truth is that maglev trains are not that efficient as they are usually depicted in the newspapers and journals. There are eddy currents in tracks generated during the motion of the train producing traction force, but these eddy currents also generate energy loss. While there are spread along the railroad, it is hardly observable but they still exist.
This concept can diminish the eddy current’s loss by utilization of the shifting magnetic field! The levitation of the train must be achieved by the electromagnetic attraction achieved between tracks and the electromagnets in locomotive and this levitating DC magnetic component produces the loss by generation of eddy currents in rails. But, with the proper approach the eddy current loss in tracks can be diminished.
The difference between this invention and US patent 782312 is in the DC component that creates levitation without superconductivity mixed with AC component that creates traction and variable adjustable PWPM modulation that obtains recuperation too.
Moreover US Pat. 782312 cannot work at all because the thrust was not adjusted to the speed as it is usually done in asynchronous electric motors on the start by switching from triangle to star windings connections. By this omission it seems that the patent 782312 is not technically achievable. However the drag effect is also not explained in this patent. This patent should be rather taken as a curiosity than as the real feasible patent just in case that it is real and not forgery done by certain group to forestall and cancel issuing of all eventual patents that may trigger huge patent obligations. The shallowness in the explanation of the essence of the drag effect may indicate that this patent actually is a forgery, quite similar to one related to the recent discovery of alleged invention of the pocket wireless phone in the year of 1906 by Charles Alden, almost a decade before the invention of the radio. The unique ability of this alleged invention to maintain several phone calls simultaneously on the same frequency implies miraculous utilization of advance spread spectrum modulation implemented completely without commonly known active electronic elements. This invention or “invention” was mentioned several times in a recent trial related to certain peculiar operation of smart phone. However, if the invention of Alden is somehow genuine one then it is the rock solid proof that there is organized action for suppressing of advance inventions. This is quite unlikely because this indicates that there are still hidden theoretical ancestors that gave the profound explanation of the propagation of radio waves that somehow remained unknown until now.
The concept of the levitating linear magnetic shifter field locomotive is shown on the following figure:
This pump is suitable for pumping of corrosive and aggressive conductive liquids. Most of corrosive
liquids are conductive ones which facilitates application of that pump.
The pump is also able to pump liquid metals through pipes resistive to extreme heat, and such pipes are generally bad conductors which makes this pump extremely suitable for liquid metals refinement.
This pump is also able to push living fish harmlessly together with other living creatures making them suitable for pumping of fragile liquids in marine applications.
The pump could be use as extremely reliable circulation pump in hitting systems and power plants preventing overheating caused by pump's malfunction. This pump is resistive to calcium carbonate deposition that is common event in heating systems.
This pump could be used for blood pumping during the heart's surgery where the blood could be
pumped trough teflon (polytetrafluoroethylene) pipe without mechanical damaging of the erythrocytes preventing coagulation.
It can be also used in artificial kidney for blood pumping.
The electrolysis of the blood should be negligible according initial calculation.
The pump is ideal for permanent automatic usage on well positions settled far away of farmers. While the pump does not require any maintenance at all just like self cleaning solar cells, this pump is ideal to be paired with such solar cells and appropriate automatic control unit, humidity and level sensors and GSM error warning system. Such configuration is ideal for occasional inspections, even annual ones.
Above linear realization of the pump could be modify to best fit requirements for submarine propulsion. The propulsion is consisted of a field of bar electromagnets settled near the submarine's fuselage which should be made from non magnetic material on that region. This field of electromagnets should be created by appropriate three-phase excitations and this field then should be able to push fluid near the surface of fuselage creating noiseless and wireless propulsion of the vessel – completely without any contact, cavity, moving part and thermal dissipation making it perfectly stealth.
The pump is especially suitable for usage on either big hydro power plants or small ones and then it
operates as asynchronous generator. Asynchronous generators are not in routine usage today, and they are only used in
pretty rear reversible hydro power plants.
Although there is significant advantage of synchronous generators over the asynchronous ones, the concept of merged asynchronous generator and the turbine is much more advance and more efficient then the couple of efficient synchronous generator and inefficient turbine, therefore the usage of the pump as asynchronous generator is quite economically and technically plausible. Direct replacement of the generator and turbine units in existing hydro power plants will increase power production for more than 25% without any modification on either accumulation lakes or dams.
The pump is also able to pump liquid salt (NaCl, i.e. sodium-chloride) which is extremely suitable for utilization in solar power plants equipped with the solar tower! The pump is also able to pump liquid sodium whish should be used in novel extremely efficient nuclear reactors able to utilize thorium as fuel directly.
The pump could be used in tide power plants too.
THE PUM AND NON CONDUCTIVE FLUIDS
The pump is also able to deal with non-conductive fluids. There are two kind of non-conductive fluids: polar and non-polar ones. The modification necessary for pumping of non-conductive fluids is relatively simple and it is consisted of additional high frequency excitation making polarization of molecules. Such fluid is able to interact with rotating magnetic field. The pump utilize following effect depicted on the following picture:
Above picture shows a dipole settled right between two opposite homopolar magnets that mutually rotate in contra directions. The force that acts to a dipole is constant regardless the distance to the axe of rotation and it only depends on the characteristic of the dipole itself:
F = (2 · B · ω) · (Q · d)
The term in first brackets is defined by external conditions, i.e. magnitude of magnetic
field B and its torsion speed ω, and the term in the second brackets is defined by the characteristic of the
dipoles themselves, i.e. charge Q and distance d between charges in the dipole.
For proper propulsion of dipoles only polarization is required. However, the DC device shown on the above picture is able only to accumulate dipoles in the vicinity of the magnets' edges. For proper fluid propelling we need to utilize AC current, just as it is a case with rotor in AC motors.
The modification necessary for pumping of non-polar liquids are much more essential and it is based on modification of core (8) and it utilize Hooper's effect and presumption that gravitation arise in annul of torsion electric fields. The test device has been able to push fluids and it is shown that force has pretty good correlation with the fluid density. The material of the core will remain uncovered in the text and it is a technological secret that will be revealed to buyer of the concept only.
However, the material of the core (8) makes this pump inadequate for all application, but it proves that the concept of the induction pump able to pump mass is possible which might be proof that mass is essentially effect of charges cancellation and gravitons are annulled couples of entangled photons. Therefore such pump is able to pump even a leaving fish; various see creatures and so one.
This concept is patent pending and it is for sale.
