Definitions
- the invention relates to an oscillating armature pump with electromagnetic drive, in particular with solar drive, wherein in a cylindrical interior a ferromagnetic piston is axially displaceable, generates a voltage applied to an outer coil coil voltage driving forces for the piston in the piston through a check valve in a flow direction shut-off flow path is arranged and a second check valve is arranged on a delivery-side pump outlet.
- the spring forces of the check valves must be overcome during a conveying movement of the piston.
- the piston has two axially spaced iron cores, which is why two axially spaced apart coil systems are used. This increases the overall length. Also in this pump, the housing outer diameter is many times larger than the effective diameter of the piston.
- Such complex vibration tank pumps according to the prior art are based on efficiency optimization, which are required in an industrial environment.
- these oscillating armature pumps cause additional difficulties in countries with a low level of development. Production, operation, maintenance and the distribution of spare parts are a serious obstacle to safe operation and an obstacle to market success due to the scarcely developed infrastructure. In such countries, a pump must be easy to manufacture and maintain with high reliability.
- the invention is therefore based on the problem to develop a vibrating armature pump with electromagnetic drive, in particular solar drive, which is due to their simple structure inexpensive and easy to manufacture and maintain, and at the same time has a good flow behavior.
- a hollow piston is arranged in a Vietnamesemagneti- see housing tube, the housing tube is wrapped with at least one coil-shaped wire winding and that the hollow piston has axially spaced sealing rings.
- An advantage of the new type of vibration tank pump described is its considerably reduced outside diameter compared to existing solutions. ser. This results from the fact that the coil-shaped wire winding is wound around the housing tube and thus rests directly on the housing tube.
- the pump has thereby a very good ratio of housing outside diameter to effective diameter of the hollow piston. The latter can reach up to 85% of the housing diameter.
- the pump according to the invention is therefore also suitable for wells with small bore diameters, which are cheaper to produce.
- Other advantages are their simple structural design and their manufacturability with simple means.
- the required output products in the form of housing tube, wire for a winding are also available in countries with a low level of development. No special tools are required for installation and maintenance.
- the arranged on the hollow piston sealing rings ensure good efficiency even with larger tolerances of hollow piston and housing and at the same time act as a barrier against contamination. They prevent their entry into the space between hollow piston and housing and thus jamming. Worn sealing rings can be replaced with common materials.
- one or more wire windings may be wholly or partially embedded in the housing tube.
- a wire winding can be molded into the housing tube or held by a potting material in and / or on the housing tube. Forming results in even smaller ones
- the housing tube consists of a plastic or of a mineral material.
- the ease of processing is another advantage.
- such pipes can be easily made locally by simple means. From these mineral materials, clay, ceramic or cement pipes can be created. Ceramic has the advantage of high abrasion resistance.
- an existing pump is resistant to aggressive media, such as those found in hot dry zones as drinking water with high salt content and higher temperature.
- the hollow piston consists entirely or partially of hard magnetic material or is formed with a thin-walled piston wall. It has proven advantageous to use permanent magnet material which results in a very good efficiency despite the simple structure. A surface coating of the hollow piston protects its material from the pumped medium. Thus, the use of media-resistant special materials can be dispensed with.
- the sealing rings consist of swellable material. Due to their swelling capability, such sealing rings adapt themselves to the housing tube and thus compensate for greater manufacturing tolerances. Furthermore, they are easy to maintain and possible wear is compensated by the swellability.
- the non-return valves arranged in the hollow piston and the pump outlet on the delivery side are advantageously designed by a ball made of non-magnetic material as a non-return element and one or more restraining bows which limit the stroke of the non-return valve.
- a ball made of non-magnetic material as a non-return element
- one or more restraining bows which limit the stroke of the non-return valve.
- one or more solar panels and an electronics unit form a voltage-generating system and are connected to the wire windings.
- Fig. 1 shows an embodiment with hollow piston in the starting position
- Fig. 2 shows an embodiment with hollow piston during the conveying movement.
- Fig. 1 shows a pump housing as a cylindrical, consisting of a non-magnetic material housing tube 1 with inflow 2 and outlet opening 3. It can be made of plastic, ceramic, concrete or the like. In the area of the outlet opening 3, a connection 4 is used for connection to a delivery line (not shown here).
- the non-magnetic housing tube 1 is wound with a coil-shaped wire winding 5.
- the hollow piston 6 may be made of ferromagnetic material as well as wholly or partly of hard magnetic material. It is also possible that - as shown here - one or more permanent magnets 8 are held on the hollow piston 6.
- the hollow piston 6 at the same time includes a required to promote the fluid check valve. This consists of non-return element 9, here in the form of a ball, restraint bar 10 and valve seat 11. As a ball material, rubber and for the restraint bar 10 stainless material has proven to be advantageous.
- the retaining clips 10 may be cross-shaped rods.
- a check valve In the region of the delivery-side outlet opening 3 is another check valve with the components check element 12, here in the form of a ball, retaining bracket 13 and valve seat 14. It prevents backflow of the fluid from a - not shown here - delivery line during the downward movement of the hollow piston.
- axially spaced sealing rings 15 and 16 are arranged at two or more locations. They are advantageously made of swellable material, which rests sealingly between the hollow piston 6 and the inner wall of the housing tube 1 under the influence of the fluid.
- a spring 17 for returning the hollow piston 6 is shown in its initial position shown here before a pump stroke. The spring 17 can be omitted if the return of the hollow piston 6 - as will be described in more detail below - by a magnetic field with a restoring force.
- the wire winding 5 is connected with the interposition of an electronic unit 18 with an electrical voltage source. Is achieved by means of an electronic unit generated voltage coil of suitable polarity, the wire winding 5 is activated, so a magnetic field is formed, which exerts a force on the hollow piston 6, which forces him out of his rest position shown here in a forward Forderterrorism This movement is in the hollow piston After the voltage / current pulse and carried out the electronic unit 18 interrupts the flow of current through the wire winding 5, the magnetic field collapses and there is no electromagnetic force More on the hollow piston 6 Due to its weight force, the hollow piston moves back to its original position. The return of the hollow piston 6 is supported in the illustration shown by a spring 17 mounted in the housing tube check valve and prevents backflow of the required fluid from a connected Forder horr
- a solar panel 19 As an example of an electrical voltage source, a solar panel 19 is shown Similarly, a wind generator, a battery or other voltage source find application
- the electronics unit 18 generates from the voltage supplied by the solar panel 19, the desired voltage pulses for the generation of a magnetic field in the wire winding 5 Through the When this reaches a certain voltage level, the electronic unit activates the wire winding 5, resulting in the above-described conveying movement of the hollow piston 6.
- the capacitor 20 is thereby discharged.
- the capacitor 20 is recharged and after recharging the capacitor 20, the process begins again
- the electronics unit 18 can also generate voltage pulses with reversed polarity for a return of the hollow piston 6, wherein The spring 17 shown in FIG. 1 can also be dispensed with. Equally well, by applying a voltage to a separate wire winding, which is arranged in particular in the region of the top dead center of the conveying movement, the Return of the hollow piston can be achieved. It is also possible to generate the restoring force by applying a voltage of positive polarity to a wire winding with reverse winding sense.
- Fig. 2 shows another embodiment of a pump during the conveying movement.
- the non-magnetic housing tube 21 is wound with a coil-shaped wire winding 5, which is here completely formed in the housing tube.
- the wire coil 5 may be wound on a pipe and held thereon by coating with a resin layer or potting material.
- the housing tube 21 additionally has a connection 22 for possible connection to a
- the hollow piston 23 - here entirely made of hard magnetic material - is shown during its conveying movement.
- the check valve located in the hollow piston 23 is closed and due to the displacement effect, a fluid located in the housing tube 21 is conveyed through the delivery-side outlet opening 24.
- the provision of the hollow piston 23 after the conveying movement takes place here in contrast to Fig. 1 not by means of a spring, but by a magnetic field with a restoring force.
- the electronics unit 25 generates voltage pulses with reversed polarity. In the illustration shown, this is achieved by means of a charging and discharging process of a second capacitor 26.
- the capacitor 26 is charged during the conveying movement of the hollow piston 23.
- the electronics unit energizes the wire winding 5 to return the hollow piston 23 with a voltage pulse of suitable polarity, in the arrangement shown with reversed polarity compared to that during the conveying movement.
- the capacitor 26 is discharged.
- the arrangement can also be driven by other solar electronic circuits or by other systems generating suitable voltage pulses.
