  • a tube arrangement which can comprise a plurality of tubes or lumens which can be arranged in a head of a peristaltic pump.
  • the hose assembly can provide a flow rate or volume capacity generally equal to or greater than that achieved with a comparable prior art hose while operating at higher pressures than those achieved using the prior art hose technology are possible.
  • a dosing device for liquid agents is known, with which different liquid agents can be transported from separate storage containers into a treatment room or into a mixing chamber by means of a pump device driven by a drive motor, in particular for washing machines or dishwashers, in which different liquid agents are used alone or mixed in the washing or Rinsing container can be fed,
  • the metering device for conveying the liquid having a pump device in the manner of a hose pump, which is equipped with support devices rotatably mounted in the pump head for squeezing rollers or squeezing rollers acting on the pump hose, the metering device having at least two or more pump devices, each with a pump head has, the pump heads being mounted on a drive and coupling shaft, the drive and coupling shaft carrying coupling elements which are designed to be axially displaceable and which correspond to the pumping operation Coupling elements can be brought into engagement in the roller carriers of the pump devices, and the pump devices are each driven by a drive motor for pumping operation.

  • the object of the invention is therefore to avoid clogging of the nozzles, starting from a fluid tank for several nozzles, in order to enable electrohydrodynamic atomization in the required quality.
  • the invention relates to a pump system with an atomizer nozzle system with at least two atomizer nozzles, an electrohydrodynamic atomizer, the pump system comprising at least one hose package and at least one pump rotor and at least one rolling body to form a rolling area of a peristaltic pump.
  • the pump system is characterized in that the hose package comprises at least the same number of hose channels as the number of atomizer nozzles, preferably at least two, in particular three hose channels, and that each hose channel is assigned to a connection of an atomizer nozzle and connects it to the rolling area.
  • each individual atomizer nozzle with its own hose channel forces a volume flow through each individual atomizer nozzle, so that in the event of an incipient blockage, the subsequent volume of fluid conveyed forcefully pushes out a clogging plug, and thus a fluid flow through the nozzle is always guaranteed.
  • hose package with several hose channels offers the advantage that a common routing of the hose package in the device can easily be provided without having to route individual hoses.
  • At least two, preferably three pump rotors are formed, with each pump rotor moving at least one rolling element or at least one group of rolling elements and being assigned to at least one hose channel.
  • each hose channel directly connects a fluid tank through the rolling area to an atomizer nozzle.
  • each nozzle is directly supplied with fluid from the fluid tank, without any hydraulic communication/interaction, e.g. pressure equalization or a resulting volume flow between the channels of the individual transport paths.
  • any hydraulic communication/interaction e.g. pressure equalization or a resulting volume flow between the channels of the individual transport paths.
  • a predetermined volume flow is enforced at each individual atomizer nozzle, which leads to process-reliable electrohydrodynamic atomization.
  • a hose channel runs from a fluid tank to in front of the rolling area, a division into at least two, preferably three or more hose channels is formed in front of the rolling area and these hose channels run through the rolling area up to an atomizer nozzle assigned to the respective hose channel are arranged.
  • a single hose channel from the fluid tank to the rolling area facilitates the connection to a valve system of the fluid tank and saves installation space and costs, since less hose material between the fluid tank and Rolling area must be provided.
  • the rolling area in which the delivery pressure for the application of the individual atomizer nozzles is generated, separate hose channels must then be provided so that a division takes place in advance, for example by Y-elements or the like.
  • At least one atomizer nozzle is connected to at least two hose channels.
  • each hose channel conveying a defined volume of fluid
  • increased process reliability and error avoidance can be achieved in electrohydrodynamic atomization, since smaller cross sections can be used and redundancies can be achieved.

  • At least two, preferably three, in particular four rolling bodies are formed in the pump system, with each rolling body being individually assigned to at least one hose channel.
  • the rolling body groups comprising several rolling bodies, for each hose channel, an offset of the rolling movements between the hose channels can be generated, for example by arranging the individual rolling body groups at an angular offset on the pump rotor in order to generate a uniform fluid flow and especially to reduce pulsation effects.

  • the invention further provides a method for operating an electrohydrodynamic atomizer, wherein the atomizer comprises at least one, in particular two, preferably three or more atomizer nozzles, and a pump system according to the invention described above is included and a defined volume flow of a fluid is imposed on each atomizer nozzle via the pump system .
  • Electrohydrodynamic atomization is based on the instability of electrically chargeable fluids, especially fluids that are sufficiently electrically conductive under high voltage, in a strong, inhomogeneous electric field.
  • the fluid is subjected to high voltage.
  • the fluid deforms into a cone, from the tip of which a thin beam, a so-called jet, is emitted, which immediately breaks up into a spray of finely dispersed drops.
  • the drops Under certain conditions, in Taylor cone mode, the drops have a narrow size distribution.
  • An expedient development of the method is characterized in that a hydraulically generated free jet in the form of a fluid column is created at the outlet of an atomizer nozzle, which only forms atomization after a free jet area through electrohydrodynamic interaction.
  • the free jet generated allows the electrohydrodynamic interactions to develop more degrees of freedom, so that finer atomization is achieved outside of the previously geometrically defined nozzle channel.
  • a diameter of an opening of the atomizer nozzle is from 0.1 mm to 0.3 mm, preferably 0.2 mm and/or a length of a fluid channel in the atomizer nozzle is from 3 mm to 15 mm, preferably in the range of one Insulator a free jet of 10 mm to 15 mm is formed.
  • the fluid is brought far in front of the nozzle opening, and the atomization process can develop freely relative to the environment, the direction of the atomization being determined by the general kinematics, in particular by the hydraulic delivery of the fluid flow.
  • a hose package refers to any collection of hoses that can be used in a peristaltic pump (roller pump). It is irrelevant whether the hose package is designed as a jointly extruded multi-channel hose or as a combination of individual hoses.
  • a pump system in the sense of the invention includes, in addition to the actual pump unit, also the necessary hoses, since in a peristaltic pump (roller pump) the pump volume is given by that hose section which is processed by the rolling elements in order to move a fluid volume contained therein in front of the rolling element.
