  • Potting compounds to moisture-tight encapsulate electronic circuits or adhesive to tightly interconnect components are often applied in the industry by means of appropriate automated application method via dosing machines on the corresponding components, and must therefore be constantly supplied with the appropriate material.
  • such a consumer is connected via lines to a storage device in which is in a mostly pot-shaped Reservoir is the appropriate material.
  • a pump unit is arranged, which causes the transport of this often viscous material.
  • piston pumps are often used, which wear less quickly even with abrasive material to be conveyed and are also cheaper to produce, but do not provide a continuous flow.

  • the wear is reduced by the material to be delivered by the pumping element comprises at least one elastic element, preferably the elastic element itself is the pumping element.
  • the elastic element peripherally circumferentially tightly clamped, at least with respect to the pump housing, with sleeve-shaped in the form of a bellows at the opposite end of the bellows against a non-elastic pumping element.
  • the elastic element is arranged so that it is in pumping operation only on one side with the material to be conveyed in contact, and thus divided the space inside the pump housing in a pumping space and a drive space.
  • such a pump unit also includes a controller, usually an electronic controller which controls at least all the moving components of the pump unit.
  • a bellows pump in which, as is usual in a piston pump, a pump piston in a cylinder is axially movable, but the pump piston is not tight with its outer circumference - whether it is about seals or piston rings - on the cylinder wall and shifts along this, but ends radially spaced from the inner peripheral wall of the cylinder, wherein a sleeve-shaped, elastic bellows, usually a bellows, is tightly secured with its one annular end edge on the outer periphery of the pump piston and with its other annular end edge on the pump housing.
  • Another design is a so-called diaphragm pump , in which an elastic, approximately plate-shaped membrane the interior in the pump housing - usually formed by two bell-shaped or cup-shaped, with the open sides tightly fastened to each other housing parts - the interior of the pump housing in a pumping chamber and a working space divided, and at its outer edge circumferentially tightly mounted opposite the pump housing, for example, between the two pressed against each other screwed housing halves is tightly secured.

  • inlet valve and outlet valve are arranged on diametrically opposite sides of the delivery chamber of the pump, preferably the inlet valve in the assembled state of the pump unit at its lowest point and the outlet valve at its highest point, so that the outlet valve can be particularly easily closed by a non-return valve arranged there ,
  • Such a pump can be driven in different ways:
  • a first possibility is to act on the drive space of the feed pump alternately with negative pressure or overpressure of a drive medium, for example air.
  • the pump in the design as a diaphragm pump, the diaphragm of the pump, via a drive ram, which is fixed with its front end on the side facing away from the material to be conveyed on the membrane, driven transversely to its main plane.
  • the delivery piston is driven by the drive tappet.
  • the drive tappet and / or the membrane of the feed pump can be set in motion by different drives, be it from an electric motor, for example via an oscillating drive or an eccentric drive, even easier, but in turn by a diaphragm pump, which now as Membrane drive pump is used, and whose diaphragm is connected to the other, rear end of the drive plunger.
  • drives be it from an electric motor, for example via an oscillating drive or an eccentric drive, even easier, but in turn by a diaphragm pump, which now as Membrane drive pump is used, and whose diaphragm is connected to the other, rear end of the drive plunger.
  • the drive pump is moved back and forth by creating a differential pressure between the two chambers on both sides of its membrane and reversing it for reciprocation.
  • the drive space on the one hand and the coupling space on the other hand alternately acted upon by compressed air as the working medium and opened the other room to the environment or even subjected to negative pressure.

  • the main planes of the two membranes are arranged parallel to each other, and the drive tappet and its direction of movement extend perpendicular thereto.
  • a heating device in particular in the form of electric heating coils or lines for a heated liquid medium, can be provided in the feed pump housing or even the pumping chamber in order to heat the material to be conveyed and thus make it more fluid and better pumpable.
  • a cooling device may also be necessary for individual applications.
  • a liquid sensor is preferably arranged, which detects in the event of a leak such as a crack of the membrane in the drive space in reaching liquids and reports to the controller, which then emits an alarm signal.
  • At least one pressure sensor is provided in the delivery chamber of the delivery pump or in its connections in order to know at all times the pressure conditions in the pump and in particular in the delivery chamber, so that an associated controller can react thereto, either by changing the working pressure of the drive medium or, if necessary, by delivery an alarm signal when the measured pressure exceeds a limit or a minimum pressure is not reached.

  • the storage device which comprises at least one of the above-described pump units in addition to the reservoir for the material to be conveyed, this object is achieved in that the pump unit is designed according to one of the preceding claims.
  • the bearing device comprises two such pump units that can be driven counter-synchronously to ensure a quasi-continuous delivery of the material into the outlet line.
  • pump units of different sizes instead of using pump units of different sizes, more than two pump units can be used, of which, for example, half of the pump units each are operated synchronously and can also convey into a common delivery line.
  • the two pump units are independently controllable, so that temporal overlaps of the return stroke of a pump unit and the working stroke of the other pump unit or a time interval between them are possible.
