Definitions

  • the invention relates to a diaphragm pump with two in a pump housing used on a zu felicitndes liquid or free-flowing medium, e.g. a color, acting membranes, which are actuated by means of an arranged between the membranes and on both sides of a pressure medium alternately acted adjusting piston and which are supported in the edge regions of two firmly connected to this piston rods.
  • a diaphragm pump with two in a pump housing used on a zu felicitndes liquid or free-flowing medium, e.g. a color, acting membranes, which are actuated by means of an arranged between the membranes and on both sides of a pressure medium alternately acted adjusting piston and which are supported in the edge regions of two firmly connected to this piston rods.
  • a diaphragm pump of this kind is by the DE 195 35 745 C1 known.
  • the two membranes each have a further pressure chamber associated with this embodiment, which are separated from the delivery chambers by the membranes.
  • the pressure chambers here in synchronism with the adjusting movements of the mechanically mechanically connected drive piston of an air motor controlled pressure medium supplied, so that although a pressure boosting is given, the required construction and investment costs, however, is considerable.
  • a separate control device is provided between the air motor and one of the membranes, which is susceptible to interference and builds large.
  • the membrane folds over each other, so that their flexing zones are subjected to extremely high stresses due to the alternating tensile and compressive loads. This already leads to relative short operating time to damage the membranes, so they must be replaced and in such cases, business interruptions are to be accepted.
  • the folding over of the membrane has an unfavorable effect on the delivery behavior of the membrane pump, since thereby volume changes in the delivery chambers are unavoidable and the delivery flow thereby pulsates conditionally.
  • the object of the invention is therefore to form a diaphragm pump of the aforementioned type in such a way that the membranes are not subject to changing loads during operation, but rather always maintain their predetermined installation position. A folding over of the membrane should thus be excluded, so that their stresses are low despite high delivery pressures and thus almost impossible damage.
  • the construction cost, by means of which this is to be achieved, should be kept low, yet should be given a simple design configuration trouble-free operation over a long period. Also, no changes in the volumes of the pumping rooms should occur.
  • a membrane pump of the aforementioned type characterized in that the two membranes are clamped with a mutually facing curvature or with a curvature facing away from each other with their outer edge regions fixed in the pump housing and with its inner edge regions on the adjustable piston rods and the two reaction spaces formed between the diaphragms and a cylinder accommodating the adjusting piston are filled with a hydraulic medium and positively connected to one another via a hydraulic linkage.
  • the reaction chambers accommodating the diaphragms and the connecting pipes connected thereto are to be completely filled with a hydraulic medium and hermetically sealed, the hydraulic fluid forming the hydraulic linkage being subjected to atmospheric pressure or a negative pressure of up to 0.09 MPa is and connecting the two reaction spaces line through a plug should be sealed liquid-tight or sealed. In this way it is ensured that the membranes are fixed in the predetermined position.
  • each space should be permanently connected via one or more incorporated into the cylinder openings with the immediately adjacent pressure chamber of Verstellkulbens.
  • both diaphragms always maintain the predefined installation position and do not fold over during the transition from a suction stroke into a pressure stroke.
  • the illustrated in Figure 1 and designated 1 diaphragm pump is used to convey a liquid, such as a color to be processed, from a storage container 2 to a spray gun 5 and consists essentially of two in a housing 11 arranged membrane 19 and 20, with one of Pressure medium alternately acted adjusting piston 22 are drivingly connected. Via a suction line 3, the diaphragm pump 1 is connected to the storage container 2, a pressure line 4 connects the diaphragm pump 1 with the spray gun. 5
  • the adjusting piston 22 is arranged in the embodiment shown in a cylinder 21 which is installed between the two membranes 19 and 20 with in the housing 11.
  • the pressure chambers 25 and 26 of the adjusting piston 22 is alternately supplied to the pressurization pressure medium, which is taken from a pressure line 6 and with the aid of a 4/2-way valve in downstream pressure lines 8 or 9 can be introduced, to the pressure chambers 25 and 26 respectively are connected.
  • the membranes 19 and 20 are clamped with their outer edge regions between discs 37 and the cylinder 21, with their inner edge regions, however, they are held between discs 38 and 39, which are plugged onto the adjusting piston 22 projecting piston rods 23 and 24 respectively.
  • a nut 40 screwed onto a threaded shoulder 24 1 of the piston rods 23, 24 is used, so that the discs 38 and 39, as can be seen in particular from FIG. 2, are supported on the piston rods 23, 24 offset in the edge region.
  • the diaphragms 19 and 20 are each assigned a pressure chamber 13 or 14, to which the medium to be conveyed flows via inlet ducts 15 and 16, respectively, into the housing 11, which is connected to the suction line 3. About the pressure chambers 13 and 14 downstream outlet valves 17 and 18, the medium to be conveyed in a mirror image to the channel 12 extending channel 12 first to which the pressure line 4 is connected.
  • the medium to be processed is sucked into the pressure chamber 13 by means of the diaphragm 19 driven by the adjusting piston 22, whereas the medium located in the pressure chamber 14 is expelled through the diaphragm 20.
  • the inlet valve 15 and the outlet valve 18 are opened in this operating state, but the inlet valve 16 and the outlet valve 17 are closed, so that the medium from the storage container 2 over the Suction line 3 and the channel 12 sucked into the pressure chamber 13 and can be supplied from the pressure chamber 14 via the channel 12 1 and the pressure line 4 of the spray gun 5.
  • the membranes 19 and 20 are clamped in the diaphragm pump 1 in such a way that they are with their bulges 41 and 41 'facing each other (F2) or facing away from each other (F3).
  • the membranes 19 and 20 thus lie with their mutually facing surfaces on the hydraulic linkage H and are fixed by this, since this is acted upon by atmospheric pressure or a slight negative pressure of up to 0.09 MPa.
  • the diaphragms 19 and 20 can thus not be folded down, but instead retain the position shown, as is shown in dashed lines in FIGS. 2 and 3.
  • the membranes 19 and 20 are subjected to tensile stress only, so that they can be designed to be elastically deformable in their flexing region and nevertheless have a long service life.
  • the reaction chambers 27 and 28 in the region of the piston rods 23 and 24 are each closed by a bellows 31 and 32 respectively.
  • the bellows 31 and 32 are clamped at one end to the piston rods 23 and 24, with the other ends are attached to the cylinder 21.
  • the spaces enclosed by the bellows 31 and 32 are 33 and 34 connected via holes 21 in the bore holes 35 and 36 connected to the pressure chambers 25 and 26, so that automatically a pressure equalization takes place.
  • the two diaphragms 19, 20 of the diaphragm pump 1 are clamped with convexities 41 'facing away from one another in the outer edge area between the disks 37 and the cylinder 21 and in the inner edge area between the disks 38 and 39. Since the reaction spaces 27 and 28 are also completely filled with a hydraulic fluid and communicating with each other, a folding over of the membranes 19 and 20 is also excluded. These are rather supported on the hydraulic linkage H.
  • the diaphragm pump 1 can due to the fixation of the membrane 19 and 20 by the hydraulic linkage H of the spray gun 5, the medium to be processed, since no 19 and / or 20 caused by folding the membrane changes in the volumes of the pressure chambers 13 and 14 in purchasing are fed pulsation-free. Also, the membranes 19 and 20 are subjected to tensile stresses only, a trouble-free continuous operation of the diaphragm pump 1 over a long period of time is therefore ensured.
