Abstract

Explosive force is generated in a fluid such as water enclosed in a strong steel cylinder by suddenly raising some of the fluid between concentrically placed and closely spaced electrode elements to the plasma state by means of a high voltage condenser bank with its power supply and a highly insulated electric switch in series electric circuitry with the condenser bank and the electrode elements. Means are employed to close switch contacts automatically when the power supply in parallel electric circuitry with the condenser bank has charged the condenser bank to an adjustable voltage value consistent with the explosive force required for a particular pumping need. One way check valves allow the explosive force to cause the ramming action on the fluid in one direction and entrance of new fluid into the cylinder to take place from another port from which exit is prevented thereby providing a one direction ramming action.

FIG.5

mv'mok W1 R ZWQ 4% SHOCK PLASMA HYDROLIC RAM This invention is a type of hydraulic ram somewhat similar to the hydraulic rams which derive energy to pump water from the momentum of streaming water whereby when the streaming water is suddenly stopped by a valve closing at the downstream end of the column of water the pressure surge that follows is used to open another valve and force the water into another channel where the same pressure is able to carry the water to a higher elevation. This invention then is similar in that a downstream valve is closed and in that fluid is rammed by means of a pressure surge through a valve which admits water or fluid into an adjacent channel where the same pressure carries it to a high elevation and after the surge this check valve closes to prevent the fluid from returning down the channel. However, the inventive concept here consists in deriving the energy for the ramming effect not from the momentum of streaming water or fluid but from an explosive plasma caused by the discharge of a high-voltage, high-amperage condenser bank across a two element electrode immersed in water in a pressure chamber. This pressure chamber may be separated by a free floating piston from the fluid to be rammed or it may simply consist of the electric discharge in the water itself that is being rammed provided the housing and the valves which contain the water are of sufficient strength to sustain a pressure surge of the magnitude produced by a shock plasma. The mechanism of the electrode which produces the pressure surge from the shock plasma is briefly described. When electric current from the condenser bank is caused to pass from one element of the electrode to the other through water the water is instantly ionized and converted to a highly conductive plasma which reacts as a resistance would for the production of heat under the influence of a great surge of voltage and amperage. Electric energy is thereby converted to heat energy in a manner rapid enough to produce a strong explosive effect. It is the pressure surge from this explosive effect which is desired and which does the work in this invention which in ordinary hydraulic rams is done by the pressure surge caused by suddenly stopping a streaming column of water of fluid.

The drawings which follow will help to clarify the inventive concept and to explain it in greater detail.

A brief description of each figure follows.

FIG. 1 is a physically strong two element electrode.

FIG. 2 is a transverse view of this electrode showing the concentric placement of the electrode elements and their separation by high-voltage insulation.

FIG. 3 is the steel cylinder ram housing with plugs at both ends into which are inserted check valves and electrode.

FIG. 4 is a high-voltage electric switch.

FIG. 5 is a schematic drawing of automatic switch closing mechanism.

FIG. 6 is adaptation of basic ram as shown in FIG. 3 to pump fluids other than the fluid being used to produce the plasma.

FIG. 1 depicts the two element electrode which is used to produce the percussion or pressure surge in the water by means of electric discharge across its elements through the water. Of this FIG. 1 is the outer conductive element of the two element electrode. It has the physical strength to support inner element and insulation under impact of explosive effect. It is electrically connected to sleeve 2 which carries grounded potential from the condenser bank. Number 3 is the second electrode element at the center of the electrode and is electrically connected to cable 6 by connecting sleeve 5. Number 4 is a polyester plastic embedded with fiberglass or a very strong ceramic. Its purpose is to electrically insulate electrode 3 from electrode 1 and to rigidly support electrode 3 which it does by means of its strength and by threading. It is able to sustain shock as well as high voltage. Number 7 is high-voltage insulating sleeve embedded in plastic insulation 4 and encircling cable 6 the entire length of the cable to the high voltage switch which engages the condenser bank.

FIG. 2 is a transverse sectional view showing relative positions of 1, 2, 3 and 4 which numbers are the same representations as in FIG. 1. This view is for the purpose of explaining that the radial separation in distance of 1 from 3 is important with respect to the voltage and capacitance in the condenser bank. When a voltage of 6,000 volts was used with a. condenser bank of 400 microfarads a strong pressure surge was produced in water when the separation radially between the outer surface of electrode 3 and the inner surface of electrode 1 was three-quarters of an inch and the diameter of inner electrode 3 was one-fourth of an inch. Less voltage and capacitance is required for lesser power requirements.

FIG. 3 illustrates the basic ram elements less condenser bank, power supply, switching and automatic controls. In FIG. 3 number 10 is the electrode described in FIGS. 1 and 2 shown now in its position in the ram. Number 12 of this figure is a strong steel housing in the form of a cylinder threaded on the inside.

Check valves

13 and 14 are of the heavy duty variety and are for the purposes respectively of emitting only and admitting only water into compression cavity 16. Threaded disc 15 receives by means of threaded holes check valve 13 and electrode 10. Threaded disc 17 similarly by means of threads is screwed into cylinder 2 and in turn receives check valve 14 by means of thread- FIG. 4 illustrates a high-voltage, high-amperage switch which can be remotely or automatically controlled by the current admitted to a solenoid which controls it. Contact points 21 of this switch are constructed of heavy pieces of copper or tungsten. Number 24 is a stationary support for a contact point constructed of a strong tube of electrically insulating plastic. Moveable lever arm or armature is constructed of the same material as 24 and this 25 is connected on its lower end to hinge 28 by means of which it can rock back and forth with a long swing of several inches to move contact points in and out of contact with each other. Insulating terminal 22 with connector enables flexible cable 26 to be connected to contact point 21 and it facilitates connection of same cable 26 to remainder of circuitry. Solenoid 23 with moveable arm extending on the left and connecting terminals at its base has magnetic windings which when energized pull lever arm and lever to the right. The function of pungee cord 27 which consists of a heavy band of rubber is to absorb shock from the fast acting solenoid and its lever arm and prevent sudden strain on lever arm 25. The purpose of spring 29 is to close the contact points and to keep them closed when the current is off thus preventing the accumulation of an inadvertent charge on the condenser bank.

FIG. 5 is a schematic diagram of basic components and automatic discharge mechanism. Electrode is described in more detail in previous figures. Switch 32 is the one described in FIG. 4. Condenser 33 represents the high-voltage large capacitance which when discharged by means of the switch 32 through water across elements of electrode 10 produces the surge in pressure. Rectifier 34 in conjunction with high voltage from transformer 35 charge condenser bank 33. When voltage over 6,000 volts is used and a condenser capacitance value of 400 microfarads is charged a very powerful pressure surge is obtained. The time required for the charging process is dependent upon the resistance of the high-voltage winding. If charging and discharging are too rapid and heat build up exceeds heat capabilities of transformer rectifier or condenser banketc. a resistance may be added in series between the transformer and rectifier. The following elements contribute to an automatic operation of the device.

Voltage divider 36 across the condenser bank is of the variable variety and has the function of sampling a calibrated fraction of the total voltage desired across the condenser bank and to use this as an index voltage for energizing relay 38 through ionizing tube 37 which gives positive on-off action to relay 38. When relay 38 is energized contacts open de-energizing electric switch 32 which causes it to engage its contact points thereby discharging condenser 33 through electrode 10. By setting sliding contact of voltage divider 36 closer to the condenser banks lower plate as drawn in the diagram more voltage must charge across the condenser bank before there will be sufiicient voltage to ionize the gas in the ionization tube 37 and energize relay 38 causing its points to open and the points of 32 to close. When condenser bank has sufliciently high voltage capabilities 10,000 volts with 800 microfarads can be used for extreme pressure surges for very deep wells or high pressure pumping and 6,000 volts with 100 microfarads or even less can be used for lower pressure requirements with variations in between. The only real limits to be set are those depending upon pressureand shock sustaining capabilities of ram housing and piping as well as electrode separation, higher voltages requiring greater separation of electrode elements.

FIG. 6 is very similar to FIG. 3 with the exception that there is an addition of a free floating piston springloaded to hold it at the upward end of its stroke. The fluid such as water in cavity 48 is separated from another fluid such as oil in cavity 46 by means of free floating piston 49 which is mounted in cylinder 40 which is open on its lower end and filled in its portion beneath the piston with the fluid from cavity 46 into which cavity this part of cylinder 40 extends. The pressure and explosive shock which takes place in cavity 48 is transmitted to the fluid in cavity 46 where

check valves

43 and 44 convert this alternating pressure into a fluid flow upward and out from check valve 43 and inward through check valve 44. Again as in FIG. 3

discs

47 and 5 are threaded to cylinder 42 to form the main pressure vessel. Threaded holes through

discs

45 and 47 admit and support electrode 1 and

check valves

43 and 44. Pipe 41 maintains water in plasma forming chamber 48. An alternating pressure-vacuum on this line exhausts unwanted residual gases from the plasma and maintains the water level immersing the electrode elements.
