Definitions

  • the invention relates to a pump for delivering a constituent pump fluid, a separation device, and a rotor shaft for a pump according to the preamble of the independent claims 1, 11, and 14.
  • the pumps at such or other poorly accessible places should have as little maintenance and in particular as little as possible need for externally supplied supplies, such as to have special lubricating oil.
  • the use of the medium to be pumped as lubricant is the means of choice, since the medium to be pumped is of course already available in the pump, in practically any quantities, so that no lubricant has to be provided separately from the outside and the lubricant must not be replaced after a certain period of operation, because constantly fresh and unused lubricant from the pumped medium itself is available.
  • a lubricant contaminated with sand can cause considerable damage to the parts to be lubricated, because the hard sand grains damage the surfaces of the components to be lubricated, which are often made of relatively soft metal which can eventually lead to failure of the pump.
  • the hardening of the corresponding parts such as the rotor shaft of an impeller of the pump or the rotor shaft bearing form static or rotating counterpart and bearing components, of course, a measure that is on the one hand very complex and therefore expensive and ultimately does not solve the problem actually because even Hardened parts with time of rubbing load, for example by sand contained in the lubricant, can not withstand long term.
  • Another point is that, for example, the width of the lubricant gaps between the rotating and / or static parts of the bearings often can not be reduced to the desirable level, because otherwise the harmful influence of hard, non-compressible ingredients such as sand would be so great that premature wear of the corresponding bearings would be inevitable.
  • the fact that the bearing gaps are not optimally adjustable by such restrictions, the smoothness of the stored parts can be adversely affected, and by Not optimally adjusted lubricant gaps can cause harmful vibrations in the operating state, which can ultimately also lead to premature wear.
  • liquid or gaseous ingredients can adversely affect the lubricating behavior, because, for example, the viscosity, ie the viscosity of the pump fluid used as a lubricant for use as a lubricant is poor or not at all suitable.
  • the object of the invention is therefore to propose a pump for pumping an ingredient comprising a pumping fluid, in which the medium to be pumped can be used simultaneously for lubricating rotating parts of the pump, in particular for lubricating the rotor shaft of the pump rotor, wherein the from the prior art known harmful influences of the ingredients are largely avoided on the lubrication process.
  • Another object of the invention is to provide a separation device and a rotor shaft for such a pump.
  • the invention thus relates to a pump for pumping an ingredient comprising a pumping fluid, wherein in the operating state the pumping fluid provided at an inlet pressure at a low pressure side of the pump can be conveyed to a high pressure side of the pump by means of a pump rotor rotatably mounted in a pump stator about a rotation axis.
  • the pump rotor is configured and arranged via a rotor shaft in a shaft bearing that between the rotor shaft and the shaft bearing in a lubricating ring gap, a lubricating film can be formed from a lubricating fluid formed from the pumping fluid.
  • a separation device is provided on the rotor shaft, with which a specifiable amount of the ingredient can be separated from the pumping fluid by means of a centrifugal force in the operating state for providing the lubricating fluid.
  • a separation device is provided on the rotor shaft, with which in the operating state a predeterminable amount of the ingredient, often sand in practice, can be separated from the pumping fluid by means of a centrifugal force.
  • the pumping fluid to be pumped by the pump for example, with sand loaded crude oil, which is conveyed from a raw source through the pump in a common storage, be promoted from the high pressure side of the pump into a chamber of the rotor axis co-rotating with the separation device at the end of the rotor axis ,
  • the pumping fluid is exposed in the rotating separation device to the centrifugal forces acting there due to the rotation and is conveyed to the outside, for example, into an outer annular chamber of the separation device.
  • the sand Due to the higher density of the sand compared to the liquid portion of the pumping fluid, the sand will accumulate under the centrifugal force at the outer edge of the annular chamber of the separator, so that form at the outer edge of the annular chamber, a sand highly enriched phase of the pumping fluid over a corresponding discharge opening is preferably discharged back to the low-pressure side of the pump and not for lubrication, for example, the rotor shaft is used.
  • the removal of the pumping fluid to be used for the lubrication takes place at a further inside diameter of the annular chamber of the separation device, where a phase of the pumping fluid has accumulated with low sand concentration.
  • fluid ingredients such as liquid or viscous high-density ingredients, which contains the Pumplfuid
  • the portion of pumping fluid to be used for lubrication has a predetermined suitable viscosity, which is not too high, for example, because tougher portions are removable with the separation means.
  • gas fractions are dissolved in higher viscoses and / or in higher density fluid constituents or are enclosed, for example, in the form of bubbles, and thus likewise separated off by the inventive separation device.
  • inventive separation device for example, other processes known per se can contribute to the fact that not only components of higher density but also of lower density can be deposited via the separation device because they are entrained by the components of higher density.
  • the separation device is connected to the high-pressure side of the pump via a supply line.
  • the feed line can be, for example, an integral component of the pump housing, in particular a bore extending in the pump housing or pump stator or bore-like connection opening, or else the feed line can also be realized by a separate line which connects the high-pressure side to the separation chamber.
  • the separation means co-rotating with the rotor shaft about the rotation axis comprises an outer annular chamber to which annular chamber for deposition of the ingredient is provided a substantially tangentially oriented Abscheideö réelle, the Abborgeö réelle particularly preferably for discharging a solid via a Abscheidetechnisch connected to the low pressure side of the pump is.
  • the Abscheide in particular an integral part of the pump housing, in particular a running in the pump housing or pump stator bore or hole-like connection opening, or the Abscheidetechnisch can also be realized by a separate line connecting the separation opening of the separation chamber with the low pressure side Pump connects, or connects to another location with low pressure, the ingredient, so in practice often sand or other liquid or gaseous fluid component of the pumping fluid, while preferably, but not explained above, a higher density than the phase of the pumping fluid used as the lubricating fluid.
  • the shaft bearing in which the rotor shaft of the pump is optimally supplied with the cleaned of the ingredient phase of the pumping fluid for lubrication the lubricating ring gap is in particular fluidly connected in particular by means of a lubricant opening with the separation device that at least partially freed from the ingredient Lubricating fluid to the lubricating ring gap for lubrication of the shaft bearing via the lubricant opening can be fed.
  • an additional lubricant line can be provided such that a predeterminable amount of lubricating fluid is discharged from the separation device, and can be used to feed a further lubrication point of the pump.
  • the lubricant line in particular an integral part of the pump housing, in particular a running in the pump housing or pump stator bore or hole-like connection opening, or the lubricant line can also be realized by a separate line, the separation device of the separation chamber with the other lubrication point in the pump connects.
  • the separation device can either be detachably connected to the rotor shaft, wherein the separation device can be designed, in particular, as a separation disk which can be screwed to the rotor shaft. It is of course also possible that the separation device is an integral part of the rotor shaft, wherein the separation device may be in particular a separation disc integrally connected to the rotor shaft.
  • the invention further relates to a separation device for a pump according to the invention wherein the separation device is particularly preferably configured as a separation disc which can be screwed to a rotor shaft of the pump.
  • the separation device comprises in particular an outer annular chamber, on which annular chamber for depositing an ingredient, in particular sand, a preferably substantially tangentially oriented separation opening is provided.
  • the invention finally also relates to a rotor shaft for a pump with a separation device of the present invention, wherein the separation device is particularly preferably releasably connectable to the rotor shaft.

  • the pump according to the invention which is hereinafter referred to in its entirety by the reference numeral 1, is used very generally and in particular in the specific embodiment of FIG Fig. 1a for the promotion of an ingredient 21 comprising pumping fluid 2.
  • the ingredient 21 in the example of Fig. 1a to 1c is essentially sand, as an impurity in the pumping fluid 2 is present in intolerable quantities.
  • the pumping fluid 2 is petroleum which is provided at an inlet pressure P1 at a low-pressure side LP of the pump 1 and is conveyed to a high-pressure side HP of the pump 1 in the operating state by means of a pump rotor 4 rotatably mounted in a pump stator 3 about a rotation axis A according to the arrow P.
  • the pump rotor 4 is configured in this way and arranged via a rotor shaft 5 in a shaft bearing 6, that between the rotor shaft 5 and the shaft bearing 6 in a lubricating ring gap 21, a lubricating film 20 from a lubricating fluid 200 formed from the pumping fluid 2 can be formed.
  • a separation device 7 is provided on the rotor shaft 5, with which a predeterminable amount of the ingredient 21 can be separated from the pumping fluid 2 by means of a centrifugal force in the operating state for providing the lubricating fluid 200.
  • Fig. 1a is shown schematically, is for supplying the constituent 21 pumping fluid 2, so here the petroleum, the separation device 7, which is designed as a screwed to the rotor shaft 5 of the pump 1 with screws 70 separation disc, via a supply line 8 with the high pressure side HP of Pump 1 connected.
  • the separation disk is covered by a cover D, through which the pumping fluid 2 is supplied to the separation disk.
  • a separation disc comprises an outer annular chamber 71, wherein on the annular chamber 71 for depositing the ingredient 21, a substantially tangentially oriented Abscheideö réelle 72 is provided.
