Definitions

  • the invention relates to a pump in which a piston hanging in a riser pipe on a pump rod is moved up and down in a pump housing at the bottom of the riser pipe by an above-ground pump drive.
  • the pump rod is usually screwed together from rods of standardized structural steel, for example 7.5 m in length.
  • the pump linkage is very heavy.
  • the object of the invention is to provide a pump rod assembly for pumps which avoids or reduces the problems which occur with known rod assemblies.
  • the pump linkage consists of several, essentially parallel, but not adjacent, unidirectionally reinforced fiber composite rods, each of which has a cross-sectional area of less than 1 cm 2 that remains constant over the entire length.
  • a linkage is constructed from several fiber composite rods, a simple adaptation to the requirements can be achieved in a simple manner by means of their number.
  • a coiled endless strand of fiber composite rods for example with a cross section of 0.75 cm 2 , is sufficient to cover all practical tasks.
  • the fiber composite rods run in any case from the lower clamping plate anchoring through to the upper end, since an adjustment of the cross section, as is sometimes done with steel rods, is not necessary and does not bring any cost advantages.
  • the composite fiber rods are made of unidirectionally-reinforced material, as described for example in EP-A-0000734 and as it is, for example, under the trade Polystal ® commercially. All fiber composite rods with 70 to 85% by weight of continuous fibers made of glass fibers, carbon and aramid fibers are suitable. Epoxy, polyester, polyurethane and phenolic resins can be used as reaction resins.
  • the bulk density is between 1.4 and 2.2 kg / dm 2 . Areas between 20 and less than 100 mm 2 , preferably 40 to 80 mm 2 , are suitable as cross sections.
  • the tensile strength is between 1000 and 2000 N / mm 2 .
  • the bending modulus is - based on the entire cross section - 40,000 to 20,000 N / mm 2 .
  • the fiber composite rods in the specified dimensions can be wound on drums. This significantly facilitates transport and feeding in the riser.
  • the pump linkage according to the invention is extremely suitable. It can be useful to provide guide elements in the form of spacers on the linkage at several points in the riser pipe. They preferably consist of thermoplastic polymers which, for. B. can be attached to the pump linkage by clamping. The number and arrangement of the spacers can also influence the vibration behavior of the pump linkage.
  • the pump linkage in the upper region of the riser pipe can also be sealed in a similarly simple manner.
  • the conventional “poling rod” requires the so-called “polishing rod”.
  • the pump linkage is insensitive to corrosion.
  • each individual fiber composite rod can also be checked for its usability in the installed state. Even with particularly high quality material, it is often unavoidable under the given circumstances that individual fiber composite elements are damaged will. This had catastrophic consequences for the pump rods used up to now, because it can take several days for a pump to be recovered if the pump rod breaks.
  • the pump linkage according to the invention it can at least be ascertained in a simple manner for each individual fiber composite rod whether it is broken if an indicator is embedded in the continuous production of the fiber composite; metallic or light conductors are preferred.
  • the electrical resistance is particularly easy to measure. With light guides, you can roughly estimate how far a disturbed area is from the attenuation.
  • the severity of a damage can be assessed and, for example, a linkage consisting of twelve fiber composite rods, in which only one fiber composite rod is destroyed, may be responsible for the continuation due to the oversizing, whereas the expansion can be considered without separate control.
  • the pump linkage according to the invention can also be combined from different fiber composite rods, in particular through different fiber content or through different types of fiber reinforcement. As a result, the vibration behavior of the pump linkage is influenced.
  • individual fiber composite rods can also be covered with a thermoplastic, for example as additional protection against corrosion and mechanical damage.
  • the above-ground drive 1 moves the pump handle 3 with the so-called "horse head” 4 at the end via the crank rod 2.
  • the pump linkage 5 is continuous without any intermediate connection and consists of a number of unidirectionally reinforced fiber composite elements. At the beginning and at the end they are gripped by the upper and lower clamping plate anchors 6 and 7; the connection to the horse's head 4 and the actual pump 9 is thus established via the wire rope 8.
  • Spacers 10 are provided for guiding the pump rod 5.
  • the upper area of the riser pipe 11 is sealed with a stuffing box 12 through which the polishing rod is guided.
  • a correspondingly long plastic cylinder 13 which serves as a "spacer” and takes over the sealing function, is provided as a polishing rod in this area.
  • the riser pipe 11 is surrounded by a casing pipe 14 which is perforated in the lower region. The liquid is removed from the head 15 of the riser 11.
  • the piston 16, the piston valve 17 and the foot valve 18 are indicated by the actual pump 9.
  • FIGS. 2 and 3 Such an element for six round fiber composite rods 21 is shown in FIGS. 2 and 3.
  • the diameter of a fiber composite rod 21 is 7.5 mm here.
  • the anchoring consists of several superimposed clamping plates 22, 23, 24, 25, in which the fiber composite rods 21 are embedded, which enables a very good volumetric pressure.
  • the clamping plates 22, 23, 24, 25 are clamped together by means of expansion screws 26.
  • the expansion screws 26 also prevent the clamping plates 22, 23, 24, 25 from sliding against one another.
  • the maximum load capacity of a fiber composite rod 21 is approximately 60 kN, the modulus of elasticity is approximately 50,000 N / mm 2 ; in the case of a 2,000 m deep borehole, the weight of the unidirectionally reinforced fiber composite rods is approximately 1,200 kg; Clamping plates, polishing bar and spacers make up another 200 kg. So far, similarly powerful pump rods are unknown.
  • Fig. 4 shows a spacer 10 which is constructed essentially like a clamping plate anchor; the outer diameter is only matched to the inner diameter of the riser pipe 11, and plastic is usually used instead of steel. This prevents the rod from rubbing against the pipe wall in the event of damage or curved drill holes and improves guidance.
  • the polishing rod is similar, but longer than a plastic spacer 10.
  • FIG. 5 The monitoring of the individual fiber composite rods is shown schematically in FIG. 5.
  • An electrical conductor 31 can be inserted into each rod 30 already during the production of fiber composite rods.
  • the conductors 31 are each led out of the fiber composite rods 30 at the end. In the area of the lower clamping plate anchor 33, the conductors 31 are all connected to one another.
  • the conductors 31 led out on the upper clamping plate 32 are connected to measuring devices 34.
  • the assembly of a pump rod is possible on site.
  • the "continuous fiber composite rods" wound on winding drums are moved to the borehole.
  • the ends of the fiber composite rods and the electrical control device with the pump-side clamping plate anchoring are first installed and connected to the pump.
  • the pump is then drained into the borehole; the release speed is controlled by a braking device on the winding drum. If necessary, spacers are screwed on at certain intervals.
  • the drive-side clamping plate anchoring is installed and connected to the wire rope mounting head of the pump horse head.
  • the guide element which acts as a polishing rod, is mounted on the fiber composite rods.
