Definitions

  • the invention relates to a well pump with the features specified in the preamble of claim 1.
  • Borehole pumps of this type are designed to extract water from wells, typically wells. All water-bearing components consist of stainless steel, ie a corrosion-resistant material, the other components are at least hermetically sealed, z. B. by a stainless steel jacket.
  • the construction of the pumps is such that in the working position, ie typically when lowered into a substantially vertically extending borehole, the lowest part of the aggregate is an electric drive motor, to which the actual pump connects upwards.
  • the pump has a foot part, which serves on the one hand to connect the pump to the motor, on the other hand forms the inlet for the water to be conveyed, and finally together with the upper end disposed head portion for clamping the pump head located between the head and foot serves.
  • the pump stages of these known pumps are made of stainless steel sheet.
  • the engine is also encapsulated in stainless steel sheet.
  • the foot part which used to be manufactured in a costly manner as a sheet steel construction made of stainless steel, is used in the current pumps of the Series SP made of a stainless steel investment casting. Due to the undercuts, the cast components are quite complex, since they have to be produced with lost waxes.
  • a comparably elaborate construction is also off WO 99/25055 known.
  • the invention has for its object to provide a wellbore pump, which is more cost effective and easier to manufacture, especially in mass production, especially in view of the previously particularly complicated to produce footboard.
  • the basic idea of the embodiment of the foot part according to the invention is that, this not as before as a formed in a manufacturing process component, ie z. B. as a sheet-welded component or as a precision casting, but to build the foot of two or more components that are formed in different manufacturing processes, wherein the dividing plane of the components is chosen according to the invention so that it is arranged substantially radially . So almost in a sectional plane transverse to the longitudinal axis of the borehole pump.
  • a motor-side component of the foot part is provided, which is produced in a casting process.
  • the foot part has a pump-side component, which is produced by the metal injection molding process (metal injection molding), which advantageously has receptacles for fastening means for connection to the head part.
  • a pump-side component is used for connection to the head part and for fixing the clamped between the head and foot part pump stages.
  • the foot can be made much cheaper than has been the case, and without disadvantages in terms of functionality, in particular the strength and function of the component, namely on the one hand to form a mechanically stable connection with the drive motor, on the other hand to form a mechanically stable connection with the head part and the clamped therebetween pump stages and finally to ensure a suitable suction of the pump with a certain screening function but sufficient flow cross-section.
  • the components formed in different manufacturing processes as will be explained in more detail below, be physically separated and joined together in the further manufacturing process, for example cohesively by welding to a one-piece component.
  • a motor-side component of the foot part is provided, which is produced in a casting process.
  • the or all other components of the foot part are formed in other manufacturing processes.
  • the motor-side and produced by a casting method component advantageously receptacles for fastening means for connection to the motor and / or the head part.
  • for attachment to the engine recordings are provided, which are formed by contact surfaces are, which essentially have to transmit compressive forces, whereas the rest of the component is also claimed to train.
  • a cast component is particularly suitable here. This can be formed with a suitable construction without lost cores and thus also be produced comparatively inexpensively.
  • the receptacles advantageously formed in the pump-side component likewise essentially have to transmit compressive forces, whereas the component itself is also at the same time the component which forms the delivery fluid inlet of the pump.
  • This component is produced according to the invention in the metal injection molding process (Metal Injection Molding).
  • Metal Injection Molding Metal Injection Molding
  • a plurality of typically circumferentially arranged inlet openings can be formed, on the one hand form a screening function against coarser particles, on the other hand, however, a sufficiently large intake cross-section.
  • the metal powder injection molding process is particularly well suited because on the one hand filigree structures and undercuts can be formed without lost cores, but on the other hand highly durable and high tolerance in terms of tolerance and therefore often can be used without further post-processing components can be produced.
  • the motor-side and the pump-side component are joined together by welding, so connected to a one-piece component.
  • the motor-side component can be produced as a precision casting component and due to the shaping without lost cores
  • the pump-side component is produced by metal powder injection molding, and in this way undercuts can be realized even without lost cores.
  • the pump-side component has a cylinder-jacket-shaped component which forms the inlet openings.
  • This component then essentially serves to form the inlet openings.
  • such a component is inexpensive and efficient to manufacture.
  • the cylinder jacket-shaped component may have a flange-like part which is intended to bear against a pump stage.
  • the flange-like part is used to create the voltage applied to the foot pump stage and forms the contact surface.
  • the foot part is not only made of two components of different manufacturing processes, but formed by two or more physically separate components.
  • the cylindrical component can be clamped as a separate component in a form-fitting manner between the motor-side component and the suction side of the first pump stage, without further connections being provided.
  • This is preferably done by incorporating a diffuser or a modified diffuser.
  • the latter components are available as sheet metal components or preferably as components produced in metal injection molding, they are manufactured inexpensively in stainless steel in a variety, so that further manufacturing costs can be saved when using such a component.
  • the shots of the engine-side component, the radial division plane protrude between motor-side component and pump-side component and cover the cylinder jacket-shaped component circumferentially. Then the cylinder jacket-shaped component is not only axially clamped but also radially positively held by the towering component.
  • the pump-side component superior receptacles are typically the receptacles for the fasteners of the head part, with which the pump stages are clamped between the head and foot.
  • This arrangement has the advantage that the fact that the receptacles for the fastening means over the dividing plane upwards, so are laid out to the pump, the free space in the motor-side component for the receptacles for the fastening means to the engine is larger or the foot more compact, So can be built with comparable lower axial length.
  • the motor-side component is designed such that it has a radial intermediate wall having a recess for passing through the motor shaft, via which the motor coming and leading into the pump stages shaft is arranged freely rotatable.
  • this radial intermediate wall advantageously has circumferentially at least partially directed towards the motor projections which form the receptacles for the fastening means for connection to the head part.
  • These directed to the motor projections serve to hook-shaped ends of flat bands, which typically extend circumferentially from the headboard to the foot, to fix positively and thus define the intermediate pump stages.
  • the radial intermediate wall is advantageously provided not only with these projections directed towards the engine, but also with radially concentric with the projections, however, further inwardly lying recesses, in which the free ends of the hook-shaped ends of the bands can engage for connection to the head part.
  • the manufacturing tolerances of the hooked ends of the bands can be significantly increased and / or the axial length of the projections can be reduced. This too leads to a more compact construction or to a better accessibility of the fastening means for the drive motor in the foot part.
  • the clamping bands 5 tapers in sections, so that the clamping bands 5 are positively secured in the receptacles 6, 7 by corresponding edge side with the clamping bands 5 in contact wedge surfaces.
  • suitable other fastening systems can also be used here.
  • the foot part 2 based on the Fig. 2 to 5 is shown in detail, has a motor-side member 8, which is provided for contact with the drive motor, not shown, and a pump-side member 9, which is provided for contact with the lowermost pump stage 1.
  • the engine-side component 8 has lower seats 10 for attachment of the drive motor.
  • the drive motor has four axially parallel frontally upstanding studs, which pass through the lower ring 11 of the motor-side member 8 of the foot part 2 and provided beyond the receptacles 10 with thread and fixed there by means of a nut.
  • the ring 11 has a larger outer circumference than the radial partition 13, which thereby upwardly circumferentially formed free space on the outer circumference of the pump is used to guide the electrical connection cable, not shown in the figures, the front side led out of the drive motor and the motor-side component 8 is led out in a corresponding guide groove 15 in one of the legs 12.
  • engine-side component 8 is formed as investment casting stainless steel.

  • This pump-side component 9 is produced in the metal powder injection molding process, so that it requires no further processing after production.
  • the components 8 and 9 are at their radial division plane, which is approximately in the region of the top of the radial partition wall 13, joined together and welded together circumferentially, so that there is a one-piece foot part 2, as shown in the Fig. 2 and 4 is shown.
  • Fig. 6 illustrated foot part 2a differs from the above essentially by the fact that the motor-side member 8a does not terminate in the dividing plane formed by the top of the intermediate wall 13, but that there are four upwardly projecting, so in the direction of the pump stages 1 projections 20 are provided which essentially follow the outer cross-sectional contour in this area and form the upper receptacles 7 for connection to the tension bands 5.
