Definitions

  • the invention relates to a screw pump in single-flow, two-shaft design with an outer bearing of the two screw spindles and a pump housing which surrounds the screw spindles to form delivery chambers and the delivery chambers bounded by its inner circumferential surface outside, and a suction chamber for the medium to be sucked and a pressure chamber, which receives the medium pumped by the screw spindles.
  • Two-flow screw pumps have a housing which is divided into a suction chamber and a pressure chamber.
  • the feed screws run either directly in the housing or in a replaceable housing insert, which is inserted into the housing between the suction chamber and the pressure chamber.
  • the housing has the task of providing adequate pressure resistance for receiving the process pressure and, on the other hand, providing the shape and positional rigidity required to maintain the sealing gap tolerances necessary for the pressure increasing process between the conveying screws with one another and the conveying screws and the housing or the housing insert contactless running conveyor screws particularly high demands on the smallest possible sealing gaps to achieve high efficiency.
  • Screw pumps in two-shaft, double-flow design are technically very complicated, costly in production and maintenance and are therefore preferably used for larger flow rates, which are typically too large to promote single sources (single-well-boosting).
  • a screw pump for delivery fluids is known, which has a one-sided external storage for the conveyor screws.
  • the conveyor screws are enclosed by a housing which is integrally formed and flanged to a housing part in which the conveyor spindles are mounted this housing can be removed for maintenance. If the pump has to be serviced, it is necessary to separate it from the supply line at the inlet and outlet connection and install a completely new pump.
  • a screw pump can be disassembled and repaired on site, which is very time consuming.
  • having a pump assembly of several individual parts at the customer site has the disadvantage that a pump test with accurate determination of the performance data is not possible, so that in order to meet required performance parameters usually a complete pump replacement is required.
  • the EP 0 405 160 A1 describes a screw pump with arranged in the interior of a pump housing drive spindle and at least one axially parallel sealing spindle and with an inlet and an outlet for a zueuerndes of the spindles flow medium.
  • the spindles are surrounded by a tubular housing insert which, with the pump housing which surrounds it, delimits at least one annular space connected to the interior receiving the spindles by means of at least one opening.
  • Object of the present invention is therefore to provide a pump that is inexpensive to manufacture and maintain and is basically suitable for the promotion of multi-phase mixtures in the context of a single source funding.
  • the screw pump according to the invention in single-flow, two-shaft design with an external bearing of the two screw spindles and a pump housing which surrounds the screw spindles to form delivery chambers and limits the delivery chambers with its inner circumferential surface outside, and a suction chamber for the medium to be sucked and a pressure chamber, the by the screw spindles receives conveyed medium, provides that the pump housing is inserted in a pressure housing and fixed to the pressure housing, so that the pressure chamber, the pump housing at least partially surrounds.
  • the pressure chamber separation means for separating a subsidized multiphase mixture are provided in a gas phase and a liquid phase, so that the separated phases derived either separately or a part of the separated liquid phase over a Short circuit line can be returned from the pressure chamber to the suction chamber to provide a minimum of liquid within the pump housing, so that the screw spindles can be cooled and the gaps between the screw spindles and between the screw spindles and the pump housing can be sealed.
  • a development of the invention provides that the pump housing projects through the pressure housing, so that the pump housing has two bearing or bearing points in the pressure housing. It is provided that the pump housing is attached only on one side to the pressure housing, in particular screwed, while the not attached to the pressure housing end of the pump housing is mounted in a guide in the pressure housing.
  • the pump housing in the pressure housing is fixedly mounted on one side and slightly movable on the other side, wherein the small clearance between the pressure housing and the pump housing is sealed via at least one seal, so that no fluid from the pressure chamber through gaps in the Leadership can escape.
  • the small clearance within the guide in the pressure housing makes it possible that by the pressure prevailing in the pressure chamber no deformations occur within the pump housing, which could change the play between the screw spindles among themselves and between the screw spindles and the pump housing, but that the pump housing as a whole within the Pressure housing is slightly displaced
  • Another advantage of the embodiment according to the invention is the simpler manufacture of the pressure housing due to the lower requirements on the positional accuracy of the components, so that a cost-effective production of the pressure housing is possible.
  • the maintenance due to the complete removability of the pump housing, together with the screw spindles and the bearing unit is considerably simplified.
  • the pump housing is located within the pressure chamber, it is possible to form the short-circuit line within the pump housing, ie to establish a direct connection between the pump chamber and the suction chamber.
  • the short-circuit line dosed separated liquid phase is returned to the suction chamber, which, although sacrificing the efficiency of the pump with it, but allows for the use of the screw pump for pumping multi-phase mixtures, a much longer service life.
  • the pump housing may be arranged eccentrically in the pressure housing, on the one hand to facilitate the separation and the return of separated liquid phase through a short-circuit line to the suction side of the screw spindles and on the other hand pressure-dependent deformations of the pressure housing or not act on the bearing unit or the screw spindles that they produce a pressure-dependent deflection of the fferenspirtdeln opposite angular change of the bearing unit.
  • tension anchors for biasing the pressure housing relative to the screw spindle bearing can be arranged in the pressure housing so that a pressure-dependent angular change of the bearing unit can be set alternatively or in addition to the suitable positioning of the pump housing in the pressure housing and the choice of wall thickness and / or the use of materials can.
  • the suction chamber is formed in the pump housing, so that it can be optimally adapted to the conveyor screws with respect to the dimensioning and the fluidic design.
  • the pump housing forms part of the wall of the pressure chamber, so that the use of the pump housing is a part of the inner wall of the pressure chamber forms.
  • the pump housing is sealed to the pressure housing, with passages or flow channels are provided for the pumped medium through which the pumped medium is passed into the pressure chamber.
  • connection devices for supply lines or discharges are formed on the pressure housing, so that the pressure housing during maintenance of the pump does not have to be removed from the line network, which can be a considerable installation effort and avoid leakage problems by installing and removing complete pumps from the mains become.
  • a single-flow screw pump with two screw spindles 1, 2 is shown, consisting of mutually coupled via gears shafts 10, 20 and thereon fastened via screws rotors 11, 12.
  • the shafts 10, 20 are mounted in a bearing housing 19 and form a bearing unit 9, which is sealed against the medium to be conveyed.
  • the rotors 11, 12 are mounted in a pump housing 3, wherein the shell inner surface 3a of the pump housing 3, the rotors enclose 11, 12, so that are formed by the intermeshing rotors 11, 12 in conjunction with the lateral surface 3a delivery chambers 4, in which to be conveyed medium is conveyed from a suction chamber 5 into a pressure chamber 6 via connection channels 16. Both between the rotors 11, 12 and between the rotors 11, 12 and the lateral surface 3a there is a minimal game to keep the leak rate of the pump as low as possible.
  • the inner end of the pressure chamber 6 is realized via the outer wall of the pump housing 3, since the pump housing 3, the pressure housing 7 and thus the pressure chamber 6 protrudes.
  • the pump housing 3 is fastened by bolts 40 to a carrier plate 8, to which the bearing unit 9 is likewise fastened via bolts 41.
  • the support plate 8 in turn is coupled via tie rods 42 to the pressure housing 7, so that the pump housing 3 via the bolts 40, the support plate 8 and the tie rods 42 is fixed on one side to the pump housing 7.
  • the pump housing 3 is provided in the region of the bolts 40 with an annular flange 37 which is insertable into a correspondingly formed recess 27 of the pump housing 7.
  • the support plate 8 facing away from the end 30 of the pump housing 3 is mounted in a recess 17 of the pump housing 7, but not screwed there, but only sealed by a seal 27.
  • a further seal is sealed by means of a front plate 15, which has a through-opening 25 for introducing a pumped medium into the suction chamber 5.
  • Also threaded 26 are provided for receiving connection means or leads in the end plate 15.
  • the one-sided mounting of the pump housing 3 to the pressure housing 7 has the advantage that the modular design combination of the pump housing 3, the bearing unit 9 and the conveyor spindles 1, 2 disposed therein is decoupled from pressure deformation of the pressure housing 7.
  • the pressure housing 7 can be designed for the respective system design pressure and in principle be made arbitrarily large, wherein only the recesses 17, 27 and connection devices must be designed so that the corresponding conveyor units or conveyor modules can be mounted from pump housing 3 and bearing unit 9.
  • flanges 14 are further provided for the derivatives, which can remain permanently installed.
  • separation means for the separation of gas phase and liquid phase may be provided in the promotion of multi-phase mixtures. These may be baffles or calming zones for generating a flow velocity near zero, wherein at such locations a short-circuit line 13 is preferably provided, which connects the suction chamber 5 with the pressure chamber 6.
  • the short-circuit line 13 is formed in the pump housing 3 and arranged on the bottom, so that in the lower part of the annular pressure chamber 6 located liquid that is filled to the pump housing 3, sucked into the suction chamber 5 and there by the rotors 11, 12 moved through can be. This causes heat transfer, sealing and lubrication of the rotors 11, 12.
  • the illustrated embodiment is particularly suitable to ensure safe operation of the pump even at very different wellhead pressures that can rise from quasi-atmospheric pressures to over 100 bar.
  • inlet opening 25 or in front of pump protection filters may be integrated or arranged to retain unwanted particles and to avoid damage to the rotors 11, 12.
