Definitions

  • the invention relates to a displacement device for fluids, in particular liquids, with displacers, which dive linearly in the displacer, namely in cylindrical pump chambers in a pump housing, which are each via a suction valve and a pressure valve in flow communication, wherein the displacer each via a connecting rod to the crank pin an externally driven crankshaft are connected.
  • a fuel pump with two pairs of two pump elements, which are driven by double cams, is in the DE 10 2007 035 100 A1 disclosed.
  • Star-shaped pump configurations are from the EP 1 306 553 A2 , of the FR 1563223 , of the US 2,394,285 as well as the DE 315794 known.
  • the DE 10 2004 048 714 A1 discloses a radial piston pump for fuel injection with two pump units in V-arrangement.
  • the US application US 2007/0148016 A1 discloses a pump for fans in medical applications, in which a centrally positioned motor unit drives opposing drive shafts and lever arms four compression pistons. Another compressor for medical applications with four piston elements is from the WO 2012/162389 A1 known. Pumps with two offset working pistons, which are driven centrally, are from the WO 2013/145576 A1 , of the WO 2013/091218 A1 as well as the EP 1 437 507 A2 known.
  • the invention has for its object to provide a displacement device of the type described above, which leads to low pressure pulsations.
  • Fig. 1a and 1b show in a side view and an end view of a crankshaft 10 with attached thereto two opposing groups A, B of displacers or plungers 1, 3, 5 (group A) and 2, 4, 6 (group B).
  • the plungers of the group A are alternately arranged to those of the group B in the axial direction of the crankshaft, as is apparent from Fig. 1a is apparent.
  • the groups A and B are arranged offset by a group offset angle ⁇ of 180 ° in a boxer arrangement to each other.
  • the angle ⁇ is in accordance with Fig. 1a and 1b 180 °, but may also differ.
  • crankshaft 10 and the plunger 1 to 6 form part of a positive displacement pump whose housing and other parts are not shown; however, it is to be understood that the plungers 1 to 6 are slidably and sealed in cylindrical pumping chambers of conventional design, the pumping chambers being in fluid communication via a respective suction valve and a pressure valve to provide a fluid, e.g. To bring water to high pressures.
  • the reference numbers 1 to 6 for the in Fig. 3 plunger not shown here relate to the assignment to the associated crank pin 11 to 16, ie 1 to 11, 2 to 12, etc.
  • crank pin plungers 1 to 6 are connected via connecting rods 20 in a conventional manner by means of crossheads 21.
  • the three crankpins 12, 14, 16 are according to Fig. 5 relative to the crank pin 11, 13, 15 offset by an offset angle ⁇ arranged on the crankshaft.
  • ⁇ 30 °.
  • the Fig. 6a, b and c show the crankshaft according to the Fig. 1 to 5 in the three rotational positions 0 °, 60 ° and 90 °. Similar to the representation in the 4 and 5 are the crank pins 11 to 16 symbolized by circles, which are drawn here because of the simpler representation because of smaller than in the 4 and 5 , Unlike in these figures, however, here are all six crankpins in each of the three Fig. 6a, 6b and 6c drawn to make the wake of the crank pin by the offset angle ⁇ clear. In each circle, a reference numeral 1 to 6 denoting the respective plunger is entered. Plungers with odd reference number 1, 3 or 5 belong to the group A and promote in the Fig.
  • plungers 2, 4 or 6 belong to group B and feed down.
  • the square plunger symbol in the circle above or below the plunger reference represents the effective direction of the plunger in question. Pressurized, conveying plungers are characterized by hatching. Plungers without hatching are in the suction stroke and are pressure-free.
  • the curve g1 belongs to plunger 1
  • the curve g2 to the plunger 2, and so on.
  • Plunger at top dead center OT or bottom dead center UT have the speed zero, thus crossing the crank angle axis x.
  • the plunger 1 is at zero crank angle in the UT and begins to promote with increasing flow rate.
  • the plunger 2 is at crank angle zero already in the delivery state with increasing flow.
  • plunger 1 delivers maximum at maximum speed, while plunger 6 has reached 0 m / s in TDC, and so on.
  • the curve f in the middle diagram of Fig. 7 shows the periodic oscillation of the with a positive displacement pump according to the Fig. 1 to 5 achieved flow rate l / min between about 1550 l / min and 1610 l / min.
  • a displacement device according to an embodiment of the invention is shown, wherein the Fig. 9 the right half of the device after Fig. 8 in a side view corresponding Fig. 1a shows.
  • the same or equivalent parts are in the 8 and 9 the same reference numerals as in the Fig. 1 to 6 used.
  • the displacement device has an electric motor 30 as a drive whose continuous output shaft (not visible) with their output shaft ends 34 are each coupled to a crankshaft 10 of its own positive displacement pump 31, 32.
  • the result is a unit of a central drive 30 and thus aligned two positive displacement pumps 31, 32, which are mounted on the engine 30 flying.
  • Each positive displacement pump has a plunger group A with three plungers arranged in series, namely group A with plungers 1, 3, 5 (left in FIG Fig. 8 ) and group B with plungers 2, 4, 6 (to the right of the electric motor 30 in FIG 8 and 9 ). All plungers 1, 3, 5 and 2, 4, 6 are each arranged in series and in a same vertical plane E.
  • crankpins 11, 13, 15 of the crankshaft 10 of the group A are according to Fig. 4 in the same plane E as the plunger 1, 3, 5 arranged.
  • each plunger group of a design according to the Fig. 1 to 9 also have more than three plungers for each group.
  • There are also more than three crankpin arrangements evenly distributed around a common crankshaft, for example, four crankpins, which are distributed at an angular distance of ⁇ 90 ° around the circumference of the crankshaft.
  • the offset angle ⁇ may also be less than or greater than 30 °.
