Definitions

  • the invention relates to a device for conveying pasty in particular Media with a first diaphragm pump, the one clamped in a housing Membrane and a mechanically actuated adjusting piston which has a a space worked between the latter and the membrane in the housing filled liquid, forming a hydraulic linkage, acts on the membrane and wherein the free space is adjustable via an insert used in a return line Pressure relief valve is connected to a storage space for the liquid.
  • a diaphragm pump of this type is known from DE-19 514 316-C1.
  • this membrane pumping device has proven itself because the membrane is a Pulsating conveyance is essential.
  • highly viscous media not in large quantities can be promoted, because in this case the pulsations have a very strong effect and not a satisfactory one, especially when performing coating work Work results are to be achieved.
  • constructive measures must be taken that the pressure chamber of the Membrane pump has no dead spaces, so the vacuum as early as possible is to be built. This in turn requires that the funding volume be small and small Use plug valves that are subject to high wear. Thereby Conditional malfunctions and interruptions are often the result.
  • the object of the invention is therefore to provide a conveyor device of the type mentioned to create, in which in every pressure range only small pulsations of the conveyed Medium occur so that a good spray pattern is always given. But above all, should achieved that even high-viscosity media are sucked in despite low stroke frequencies and can be promoted continuously without it being of a major structural nature Effort required.
  • the delivery volume of the second diaphragm pump in Dependence on the diameter and / or the displacement of the adjusting piston adjust, the delivery volume of the second diaphragm pump about half of Delivery volume should correspond to the first diaphragm pump.
  • the adjustment pistons of the two diaphragm pumps can be placed on a common one Drive shaft offset by 180 ° to each other or by means of a rocker adjustable by a servo device, but it is also possible, the adjusting piston in the direction of escape to each other in the housing to arrange and by one on one between these and perpendicular to these used drive shaft attached to drive the eccentric Adjusting piston of the second diaphragm pump receiving cylinder space Connect the line with the space assigned to its membrane.
  • the two diaphragm pumps should also have a common one in the housing intended storage space for the liquid can be assigned, in which the adjusting piston are partially insertable, and the delivery line of the second diaphragm pump should be one Have check valve.
  • Pressure relief valve can not only continuously the back pressure on the Tool set and thus adapted to the work to be performed be, but the device regulates itself depending on the Back pressure, with continuous conveyance.
  • the two open spaces of the Diaphragm pumps are always the same pressure, pressure peaks thereby reliably avoided.
  • the device shown in Figures 1 to 3 and designated 1 and 1 ' is used for Promotion of particularly highly viscous media from one storage container 4 to one e.g. trained as a spray gun implement 2, which via a hose 3 to the Device 1 is connected, and consists essentially of a first Diaphragm pump 21 and a second diaphragm pump 31, which together in one two-part housing 11 are installed.
  • the diaphragm pumps 21 and 31 each have one between the two housing parts 11 'and 11' ', which is fixed by means of screws 12 are connected to each other, clamped membrane 22 and 32 and this assigned adjusting pistons 23 and 33, which are located in between these and Membrane 22 or 32 provided free spaces 24 or 34 liquid columns, which each form a hydraulic linkage on which diaphragms 22 and 32 act.
  • the diaphragm pumps 21 and 31 are provided with pressure chambers 25 and 35, respectively.
  • the adjusting pistons 23 and 33 are driven by eccentric disks 43 and 44, respectively together on a drive shaft supported in the housing 11 by means of roller bearings 42 41 are arranged.
  • the eccentric discs 43 and 44 act offset by 180 ° the adjusting pistons 23 and 33, so that they are adjusted in opposite directions to each other.
  • the housing 11 there is also a storage space 13 for the in the free spaces 24 and 34 located liquid provided via a return line 14, by means of two Channels 16 and 18 connected to the free spaces 24 and 34 and with one Pressure relief valve 15 is equipped, can get into the storage space 13.
  • the Adjusting pistons 23 and 33 are provided with slot-like recesses 30 and 40, respectively upon immersion of the adjusting pistons 23 or 33 in the storage space 13 liquid in the Open spaces 24 and 34 can flow in.
  • the two pressure chambers 25 and 35 of the diaphragm pumps 21 and 31 are through one Delivery channel 26 connected to each other, in which a check valve 27 is inserted.
  • the two channels 16 and 18 with check valves 17 and 19 equipped, and to support the return of the membrane 22 of the first Diaphragm pump 21 serves a return spring 28 which acts on the diaphragm 22.
  • the eccentric disks 43 and 44 the adjusting pistons 23 and 33 of the first diaphragm pump 21 and the second Diaphragm pump 31 actuated offset from one another by 180 °.
  • the Diaphragm 22 of the first diaphragm pump 21 is closed via an inlet valve 29 conveying medium sucked out of the reservoir 4 and into the pressure chamber 25 brought in.
  • the adjusting piston 33 of the second diaphragm pump 31 can, because the Eccentric disc 44 is arranged offset by 180 ° with respect to eccentric disc 43, dodge in the direction of the drive shaft 41.
  • the subsequent suction stroke of the Diaphragm 22 of the first diaphragm pump 21 guides the diaphragm 32 of the second Diaphragm pump 31 a pressure stroke, which in the pressure chamber 35 of the second Diaphragm pump 31 medium is thus in the interval between two Pressure strokes of the first diaphragm pump 21 supplied to the working device 2 under pressure, see above that no pulsations can be determined and thus a constant conveyance of the medium the implement 2 is given.
  • Is z. B. built up with a closed working device 2 a dynamic pressure through which the Pressure in the pressure rooms 25 and 35 and the free spaces 24 and 34 of the Diaphragm pumps 21 and 31 will increase, this speaks to these connected Pressure relief valve 15 on and the pressure in the free spaces 24 and 34 is immediately automatically, since the pressure relief valve 15 opens, to the predetermined value limited. Since the pressure in the pressure rooms 25 and 35 and the free spaces 24 and 34 is always the same, pressure peaks, which can lead to damage, avoided.
  • a bolt 46 pivotally mounted rocker 45 provided by a Servo device 47 can be driven.
  • the servo device 47 consists of a my cylinder 48 inserted on both sides by alternately feeding one Pressurized pressure medium flowing into the pressure chambers 51 or 52 Piston 49, the piston rod 50 of which acts on the rocker 45.
  • Adjusting pistons 23 and 33 of the diaphragm pumps 21 and 31 return springs 53 and 54 assigned, which act on the adjusting pistons 23 and 33 and on the housing 11 support.
  • this embodiment is in a channel 20 through which the Pressure chamber 35 of second diaphragm pump 31 is connected to hose line 3, a check valve 36 is installed, through which the pressure when the implement is closed 2 is locked in the hose line 3.
  • the adjusting piston 33' is the second diaphragm pump 31 'arranged in the axial direction of the first diaphragm pump 21 and the two Diaphragm pumps 21 and 31 'can be driven together by means of the eccentric disk 43', which is mounted on the drive shaft 41 '.
  • the adjusting piston 33 'of the second Diaphragm pump 31 'accommodating cylinder space 37 is in this case via a line 38 connected to the free space 34 'so that the adjusting movements of the adjusting piston 33' via the hydraulic linkage located between the latter and the membrane 32 be transferred to this.
  • the device 1 ' is effective in the same way as that Device 1 according to Figures 1 and 2.
