Definitions
- the invention relates to a diaphragm pump for conveying a liquid, in particular an exhaust aftertreatment medium, such as an aqueous urea solution, with the features of the preamble of claim 1. Furthermore, the invention relates to an exhaust aftertreatment system with such a diaphragm pump.
- Diaphragm pumps in particular membrane pumps which can be used in exhaust aftertreatment systems, are already known from the prior art.
- DE 10 2008 043 309 A1 discloses a diaphragm pump with a multi-part pump housing, the working diaphragm is clamped between two housing parts and axially actuated by an electric motor via an eccentric and a connecting rod. To fix the working diaphragm, the housing parts are clamped together axially.
- the working diaphragm is not actuated by a Exzenterpleuel, but a piston, which is operatively connected to an armature of an electromagnet.
- the armature When current flows through a coil arrangement of the electromagnet, the armature is pulled in the direction of the coil assembly, wherein the working diaphragm is acted upon via the armature connected to the piston with a compressive force.
- the pressure force causes expansion of the membrane into the pump working space, ie a compression of the medium located therein, which is subsequently discharged via an outlet valve. If the energization of the coil end order is terminated, a spring supported on the armature ensures the return of armature and piston.
- the working membrane contracts and causes a negative pressure in the pump working space, so that fresh medium is sucked in.
- the piston is guided by the coil assembly. This requires compliance with small form and bearing tolerances in the manufacture of the piston and / or the armature. Further, the guide portion of the piston and / or the armature is exposed to increased wear by friction. Due to the length of the piston this can also tilt, which increases the frictional forces and thus the wear.
- DE 10 2004 01 1 123 A1 discloses a further diaphragm pump with a lifting magnet as the drive, in which the working diaphragm is connected directly to an armature of the lifting magnet designed as a hollow cylinder.
- a piston for actuating the working diaphragm is thus dispensable.
- To guide the anchor this is added to a sleeve-shaped plain bearing.
- the lifting movement of the armature is limited by the housing of the electromagnet, which can lead to an undesirable noise when hitting the armature on the housing.
- the present invention seeks to provide a compact, low-noise and low-friction operable via an electromagnet membrane pump, which also has a high efficiency.
- the proposed membrane pump for conveying a liquid, in particular an exhaust aftertreatment medium, such as an aqueous urea solution comprises a working space, which is bounded by a working diaphragm and which is connectable via a first valve with an inlet and via a second valve with an outlet.
- the diaphragm pump comprises an electromagnet comprising a coil arrangement and an armature cooperating with the coil arrangement and operatively connected to the working diaphragm.
- the valves are formed in a valve plate which is arranged between the coil arrangement and the armature.
- the valve plate limited together with the working diaphragm the working space, so that the arrangement of these pump components between the coil assembly and the anchor takes place.
- the essential elements of the pump are thus integrated in the electromagnet.
- a very compact pump assembly which also - due to the separation of armature and coil assembly - is noise and friction operable.
- the lack of radial guidance of the armature also results in reduced wear.
- no form and bearing tolerances must be defined.
- the operative connection of the armature with the working diaphragm ensures a direct introduction of force and thus a high Wrkungsgrad the pump.
- the armature is non-positively and / or positively connected to the working diaphragm, for example via a screw, operatively connected.
- a clamping or latching connection can be provided.
- the ends of the working diaphragm are further fixed to the valve plate.
- a ring can be used, which engages in a corresponding receiving groove on the valve plate.
- the valve plate is at least partially embedded in a housing of the electromagnet or in the armature.
- the recessed valve plate is at the same time fixed in position.
- Dampening grooves which are preferably arranged circumferentially. At a circular plan of the working space, the damping grooves are preferably arranged in concentric circles. The damping grooves cause a damping of the movement of the armature, since the pressure build-up in the working space of the medium must be displaced from the damping grooves.
- valve plate is at least partially covered on one or both sides of at least one further plate, which preferably consists of a non-magnetic material.
- the valve plate and the at least one further plate together form a valve head, wherein the individual plates are preferably connected to each other via laser welding.
- the formation of the at least one further plate of a non-magnetic material prevents magnetic adhesion of the armature to the magnet housing when the energization of the coil assembly is terminated.
- the at least one further plate is preferably welded to the housing of the electromagnet.
- the armature arranged separately from the coil arrangement is advantageously guided in the radial direction by at least one spring.
- the spring serves to return the armature after the energization of the coil arrangement has ended.
- the spring may be formed, for example, as a helical compression spring and be supported on the one hand on the valve plate or on the valve plate at least partially covering another plate and on the other hand at the anchor.
- the spring preferably engages in a circumferential groove of the armature. If the return of the armature via a plurality of compression springs, which are arranged distributed uniformly over the circumference of the armature, these preferably immerse each in a cup-shaped recess of the armature.
- the number is at least three, preferably four or more.
- the plurality of springs are arranged at the same distance from each other Wnkelabstand.
- a protrusion for example in the form of a pin, is preferably formed on the respective plate, around which the spring end can be placed. Due to the two-sided leadership of the spring or springs and a sufficient guidance of the anchor is ensured.
- the spring or the springs can also be designed progressively.
- the armature forms at least one cup-shaped receiving space for at least partially receiving the valve plate and / or a spring.
- a centrally arranged pot-shaped receiving space can serve, for example, for receiving the valve plate.
- cup-shaped receiving spaces can be distributed over the circumference, which serve for at least partially receiving the return springs.
- the cup-shaped receiving spaces can be incorporated into a flat anchor plate by a molding process.
- the anchor is a stamped / bent part, which is particularly simple and inexpensive to produce.
- the electromagnet is a DC magnet.
- the electromagnet comprises a coil with two inner diameters.
- the highest possible number of walls can be achieved. Due to the aforementioned advantages of a diaphragm pump according to the invention, such is particularly suitable for use in an exhaust aftertreatment system for conveying an exhaust aftertreatment medium, in particular an aqueous urea solution. Because the diaphragm pump prevents the electromagnet comes into contact with the medium to be conveyed, so that it is protected from corrosion. Furthermore, therefore, a
- an exhaust aftertreatment medium in particular an aqueous urea solution proposed.
- the low-noise and low-friction operation of the pump as well as the compact design also have an advantageous effect on the exhaust aftertreatment system.

- FIG. 8 is a plan view of the armature of the diaphragm pump of FIG. 7; and FIG. 9 is a partial section through the armature of the diaphragm pump of FIG. 7.
- the present illustrated pump has a working space 1, which is bounded by a working diaphragm 2, as well as a valve plate 10.
- the valve plate 10 receives a first valve for connecting the working space 1 with an inlet 4 and a second valve 5 for connecting the working space 1 with an outlet 6.
- the valve plate 10 is fixed to a plate-shaped support member which carries on the side facing away from the valve plate 10 an electromagnet 7 as a drive of the pump.
- the electromagnet 7 comprises a coil arrangement 8 and a cooperating with the coil assembly 8 armature 9, which is arranged on the side facing away from the valve plate 10 of the electromagnet 7. to Actuation of the working diaphragm 2, the armature 9 on an anchor bolt 19, which is passed through the coil assembly 8 and mounted axially displaceable guides 18.
- the anchor bolt 19 acts on the working diaphragm 2 with a pressure force which leads to a reduction in volume of the working space 1 and thus to an increase in pressure so that the valve 5 opens and the medium present in the working space 1 can flow out via the outlet 6.
- the spring force of a spring 15 supported on the armature 9 causes it to reset, whereby the armature bolt 19 is also reset.
- the provision of the anchor bolt 19 allows an increase in volume of the working space 1, which causes a negative pressure in the working space 1. As a result, fresh medium is sucked into the working space 1 via the inlet 4 and the valve 3.
- a disadvantage is the length of the anchor bolt 19, since this can easily tilt when performing the axial movement.
- the contact surfaces in the region of the guides 18 are subject to increased wear due to friction, which reduces the life of the pump.
- the armature 9 abuts the electromagnet 7 when the coil assembly 8 is energized and the armature 9 is moved in the direction of the coil assembly 8, resulting in an undesirable noise.
- FIG. 1 A first embodiment of a membrane pump according to the invention is shown in FIG.
- the drive takes place via an electromagnet 7, which comprises a coil arrangement 8 and an armature 9.
- the coil assembly 8 is received in a housing 11 which is closed to the armature 9 by a valve plate 10.
- the valve plate 10 accommodates a first valve 3 in connection with an inlet 4 and a second valve 5 connected to an outlet 6, the two valves 3, 5 (see FIG. 3) and the inlet 4 and the outlet 6 are each arranged in a common radial plane.
- the valve plate 10 is presently composed of a plurality of plates in order to simplify the formation of the valves 3, 5.
- valve plate Covered by a further plate 13, which consists of a non-magnetic material and is connected to the valve plate 10 via a circumferential weld 20.
- the further plate 13 also has an elevation 23, which serves to guide a spring 15 for returning the armature 9.
- Another receiving space 16 of the armature 9 serves to receive the working diaphragm 2 when the armature 9 moves in the direction of the coil arrangement 8.
- the cup-shaped design of the receiving space 16 supports the
- the operative connection of the working diaphragm 2 with the armature 9 takes place here via a screw connection.
- the working diaphragm 2 has a damping cone in the form of a material thickening, by means of which the movement of the armature 9 can be braked before the armature 9 abuts against the valve plate 10.
- Another stop 21 limits the stroke of the armature 9 in the return direction.
- the ends of the working diaphragm 2 are fixed via a ring 25 on the valve plate 10, which engages in a corresponding receptacle on the valve plate 10. About the ring 25, the working diaphragm 2 can be clamped.
- the diaphragm pump shown in FIG. 2 is characterized by a very low dead volume. Almost the entire volume of the working space 1 is displaced by the working diaphragm 2, whereby the high efficiency of the pump is further increased. In addition, the flow rate can be determined with high accuracy.
- valve plate 10 By integrating the pump elements in the electromagnet 7 also the space can be significantly reduced. Contributing to this is that the valve plate 10, as shown in FIG. 2, is embedded in the housing 11 of the electromagnet 7.
- the housing 11 has a recess 22 (see FIGS. 5a and 5b) which is designed corresponding to the shape of the valve plate 10 (see FIG. 4).
- the recessed into the housing 11 valve plate is also fixed by the further plate 13 which is presently designed as an annular disc in the recess 22.
- the annular disc may have a thickness of less than 0.2mm.
- FIG. 7 An alternative embodiment of a membrane pump according to the invention is shown in FIG. 7. This differs from that of FIG. 2 in that the essential pump elements, namely the working diaphragm and the valves 3, 5 are arranged within the receiving space 16 of the armature 9.
- the serving as a pole face upper side of the housing 11 of the electromagnet 7 may therefore be formed planar, which simplifies the production of the electromagnet 7.
- To form the receiving space 16 and further receiving spaces 17 for a plurality of return springs 15 of the armature 9 is designed as a stamped / bent part. As a result, the manufacturing costs can be further reduced.
- a plate 13 is omitted, instead, a plate 14 of a non-magnetic material between the valve plate 10 and the housing 1 1 is arranged.
- the plate 14 has elevations 23 which are integrally formed (see FIG. 9) or can be applied subsequently (see FIG. 7).
- the armature 9 has, in addition to the receiving spaces 16, 17, a recess 22 into which the valve plate 10 is embedded.
- the armature 9 which is guided over the working diaphragm 2 and the at least one spring 15 radially to the electromagnet 7, has two end stops, namely the Valve plate 10 and the attached thereto further plate 13 and 14 and the stop 21.
- Principle due to the armature 9 experiences no radial forces, which is why a radial guidance of the armature 9 is unnecessary.
- the armature 9 experiences a certain radial guidance via the at least one spring 15.
- Both described preferred embodiments have the advantage that an undesirable noise development is prevented or at least significantly reduced.
- a noisy impact of the armature 9 is prevented for example by the fact that the working diaphragm 2 has a damping cone (see Figures 2 and 7).
- the working diaphragm 2 can also be provided with damping grooves 12, which bring about additional damping in that the medium must be displaced out of the grooves 12 before impacting (see FIG. 6b).
- the damping grooves 12 are preferably made of the same material as the working diaphragm, which further preferably is an elastomeric membrane.
- the valve plate 10 may be equipped with damping grooves 12 (see Fig. 6a).
