Definitions

  • the invention relates to a hydraulically driven diaphragm pump according to the Preamble of claim 1.
  • diaphragm pumps of the generic type is finally still their starting safety of great importance.
  • the diaphragm pumps in today clearly lack of safety as a disadvantage. This one is only then eliminated if additional design features are present, however additional costs. It is therefore desirable in such diaphragm pumps to have sufficient starting safety, due to which ensures that the diaphragm is at standstill of the pump, due to always existing internal leakage - even then not in direction Pressure stroke moves when there is vacuum in the pumping chamber.
  • the invention is therefore based on the object, the diaphragm pump of the generic To design the way of eliminating the described disadvantages in such a way that they nevertheless a high dosing accuracy with a simple structure and that their absorbency is not limited by gas formation in the hydraulic space is, so that a suction from vacuum is well possible.
  • the inventively designed diaphragm pump is the essential idea on the basis of biasing the membrane by spring force so strong that they a considerable pressure force on the hydraulic fluid in the hydraulic chamber exerts and that thus in the hydraulic chamber a significant overpressure against the delivery room is constructed.
  • the spring force is dimensioned so that the membrane in the suction stroke the piston also follows when in the pumping chamber vacuum is applied.
  • the spring force is such that the diaphragm at standstill of the pump even then not moved in the direction of pressure stroke, if applied in the pumping chamber vacuum.
  • the spring force is so dimensioned that the pressure in the hydraulic chamber is always at least 1 bar greater than the pressure in the pump room.
  • the design can be made such that the spring force is so dimensioned that always a differential pressure of at least 1 bar at the Membrane rests.
  • the embodiment can also be made in such a way that the sum of the differential pressure generated by the spring force on the Membrane and the holding pressure of a spring-loaded leak-relief valve always at least a cash is. It is advantageous if the differential pressure at the Membrane is very large compared to the holding pressure of the leak-relief valve.
  • the dimensioning can be made, for example be that the differential pressure across the membrane with at least 0.8 bar and the Holding pressure of the leak-relief valve with about 0.3 bar is dimensioned.
  • differential pressure at the membrane for example, to 0.8 bar in the rear Measuring the dead center of the diaphragm is merely a holding pressure at the leak-relief valve of 0.3 bar necessary to sum the desired total differential pressure of more than 1 bar.
  • the invention can be advantageous in design terms in various ways and realize. So it is possible, for example, the membrane in Direction of the suction stroke biasing strong spring force through the membrane itself, i. to produce by their shape and / or material.
  • Material for the membrane for example polytetrafluoroethylene (PTFE) in question, while a suitable membrane shape, for example, by a corresponding Pre-deformation is formed.
  • PTFE polytetrafluoroethylene
  • the membrane biasing in the direction of the suction stroke strong Spring force by at least one built-in membrane spring element, for example a plate spring to produce.
  • a structurally particularly simple realization of the invention is based lying thought arises when the membrane in the direction of Suction stroke biasing strong spring force by a arranged in the hydraulic chamber Compression spring is generated; this can be on a connected with the membrane central guide rod on the one hand on the pump housing and on the other Support at the end of the guide rod, with respect to their strength the effective membrane area is dimensioned accordingly.
  • the membrane in adaptation to the at her applied differential pressure is designed as a molding membrane.
  • the mold membrane is a circumferential Beading has the concave side to the hydraulic chamber.
  • the bead of the Stabilized shape membrane This results in no tendency to buckle, so that the membrane has a long life.
  • the inclination is To friction wear in sandwich membranes extremely low.
  • the membrane can be used as a sandwich membrane be formed with at least two membrane layers, the individual layers mechanically are coupled and the suction stroke by the spring action of the compression spring be retrieved as a complete membrane package.
  • a membrane 1 As can be seen from Fig. 1, the illustrated, hydraulically driven diaphragm pump a membrane 1, the edge between a pump body. 2 and a pump cover 3 is clamped and a delivery chamber 4 of a Hydraulic chamber 5 separates.
  • the hydraulic drive of the membrane 1 is effected by an oscillating displacement piston 6, in the pump body 2 in a bushing 7 between the hydraulic space 5 and a reservoir 8 for the hydraulic fluid back and forth is.
  • the membrane 1 is in the illustrated embodiment as a three-layer sandwich membrane formed in the form of a molding membrane with a circumferential bead 9, the concave side of the hydraulic chamber 5 shows.
  • the individual layers of the membrane 1, not shown, are in their central Area mechanically coupled by means of corresponding discs 10, 11, the interconnected, in particular screwed, are.
  • the in the direction of the hydraulic space 5 facing disc 11 carries a central guide rod 12, the extends axially to the rear in the hydraulic chamber 5.
  • On this guide rod 12 is a strong compression spring 13 is arranged, on the one hand to a Shoulder 14 of the pump body 2 and on the other hand to the corresponding shoulder-like end of the guide rod 12 is supported. Due to the As a result of this exerted strong spring force, the membrane 1 is always in the direction of her Suction strokes, i. their rear dead center, biased.
  • Compression spring 13 dimensioned such that the hydraulic fluid located in the hydraulic chamber 5 a considerable pressure force is exerted, so that thus in the hydraulic chamber 5 a substantial pressure over the delivery chamber 4 constructed is.
  • This significant overpressure in the hydraulic chamber 5 is hereby shown Embodiment always at least 1 bar greater than the pressure in the delivery chamber 4th
  • the diagram according to FIG. 2 schematically shows the differential pressure on the membrane Plotted over the stroke of the front dead center VT to the rear dead center HT,
  • the differential pressure on the membrane alone due to the previously described spring 13 is generated.
  • the spring 13 also generates in rear dead center HT of the diaphragm a differential pressure of at least 1 bar, so that thus in the hydraulic chamber 5 is always a significant overpressure against the delivery chamber 4 is constructed.
  • the differential pressure at the diaphragm 1 pressure in the hydraulic oil
  • the differential pressure is generated by spring force.
  • the effective holding pressure of the leak-relief valve 15 shown as the sum of the differential pressure at the diaphragm 1 and the holding pressure of the leak-relief valve 15 (see Fig. 1). It is always at least 1 bar.
  • the embodiment For example, be made such that the differential pressure at the Membrane 1 is at least 0.8 bar and that the holding pressure of the leak-relief valve 15 with about 0.3 bar is measured.
  • the effective holding pressure is then at the rear dead center HT of the membrane 1 at least 1.1 bar.
  • Pressure in the hydraulic oil then drops to 0.7 bar absolute or to a negative pressure of 0.3 bar.
  • Fig. 4 shows the membrane 1 in its hydraulic side installation, i. in her back Dead center HT.
  • the embodiment is made such that the pump body 2 together with the rear diaphragm coupling disk 11 a nearly gap-free surface for supporting the membrane 1 forms. This allows the membrane stand at standstill differential pressures of up to 400 bar without them Harm suffers.
  • the illustrated membrane 1 ' is designed as a wave membrane. This has a design due to their design Such inherent rigidity, that this the function of the compression spring described above 13 fulfilled and for applying the desired spring force on the membrane 1 ' can be used.
  • the dashed lines illustrate the work area such a wave membrane 1 '.
  • the illustrated Membrane 1 integrated disc springs 16. These may, for example, in an elastomeric membrane vulcanised and also fulfill the function to that they the membrane in the direction of its suction stroke with a strong spring force Pretension. Again, the dashed lines illustrate the work area such a membrane 1 ".
  • FIG. 7 schematically illustrates the usable working area of one of the previously described membranes 1 'and 1 ".
