Definitions
- the present invention relates to a method for removing the eccentric screw drive of a petroleum feed pump according to the preamble of claim 1 and petroleum feed pump according to the preamble of claim 2.
- the present invention therefore aims to provide an improvement in the removal of the drive of a petroleum-driven eccentric screw pump.
- This object is achieved with a method for removing the eccentric screw drive of a petroleum feed pump according to claim 1 and with a drive head of an eccentric screw drive of a petroleum feed pump according to claim 2.
- the invention provides a method for removing the drive head of the eccentric screw drive of a Erdöl detailpumpe, wherein a drive terminal, by means of a drive shaft or polishing rod together with hanging pump linkage, including a pump rotor of the petroleum feed pump is supported via the drive head directly or indirectly on the ground or on a riser , Is released from the upper end of the polishing rod and then the drive head of the eccentric screw drive of the petroleum feed pump of the Polishing bar is removed, and wherein prior to releasing the drive terminal on the polishing rod a maintenance clamp in a holding shell of an externally accessible two-piece lantern, which sits below the position of the drive head on the polishing rod and is supported directly or indirectly on the ground or on a riser to the polishing rod is fixed, so that the weight of the pump rod, including the pump rotor of the petroleum feed pump, and the polishing rod on a bottom plate of the holding upper part of the lantern on a sealing base of the lantern with a mechanical seal which seals a delivery space in the
- the invention provides a petroleum pump, with an eccentric screw, which includes a polishing rod and a drive head, in the operation of the petroleum feed pump, the polishing rod together with a hanging therefrom pump rod, including a pump rotor of the petroleum feed pump is supported by a drive terminal, with an externally accessible two-part lantern with a sealing base with a mechanical seal that seals a delivery space in the riser of Erdölörderpumpe from the environment, and a holding shell with a bottom plate, with which the holding shell is supported on the sealing base, is provided, and wherein the holding upper part adapted for receiving a maintenance clamp is, by its attachment to the polishing rod, the weight of the pump linkage, including the pump rotor of the petroleum feed pump, and the polishing rod on the bottom plate of the holding top of the lantern on the Di bottom part of the lantern and underneath is directly or indirectly supported on the ground or on a riser.
- an externally accessible lantern is made in two parts, the upper lantern part, ie the holding upper part is provided with the bottom plate, which thus forms an intermediate floor, which allows the maintenance clamp and the suspended therefrom on the polishing rod pump linkage on the Lower the intermediate bottom without impairing the sealing effect of the mechanical seal underneath.
- the two-part design of the lantern may be designed such that the lantern consists of two components or that the lantern is made of a part which has an intermediate floor.
- the lantern is supported by means of a lantern flange and a T-piece attached underneath on a borehole flange, which sits at the upper or above-ground end of the riser.
- FIG. 1 is a schematic, partially sectioned side view in FIG.
- the drive head 1 includes a drive motor 4 and a belt drive 5, by means of which the rotational movement at the output of the drive motor 4 is transmitted to a drive shaft or polishing rod 6 of the eccentric screw drive 2.
- the polishing rod 6 is connected at its lower end 7 within a reaching into a petroleum well 8 riser 9 with a pump rod, not shown, or connectable.
- the riser 9 terminates at its aboveground end 11 with a borehole flange 24 which is connected to a T-piece 12, which in turn is connected to a lantern flange 13, via which a lantern 14 to the above-ground end 11 of the riser 9 is tightly fitted.
- a mechanical seal 15 is arranged, which seals a delivery chamber 16 in the riser 9 relative to the environment 17.
- the polishing rod 6 and the adjoining in the depth direction of the oil well 8 pump linkage (not shown), including the not visible in the figure pump rotor of Erdöl conceptpumpe 3 are based on a drive terminal 18 on the drive head 1 of the eccentric screw drive 2 of the Erdöl detailpumpe 3, which Drive head 1 in turn is ultimately supported on the wellbore 24 via other components.
- the drive terminal 18 is seated during normal pump operation at the top 19 of the drive head 1 of the eccentric screw drive 2 on the polishing rod. 6
- the drive head 1 To perform maintenance on the drive head 1, the drive head 1 must be deducted from the polishing rod 6.
- the present innovation on the other hand is that the lantern 14, which is supported on the flange flange 24 via the lantern flange 13 and the tee 12, is now divided into two parts.
- the mechanical seal 16, which seals the delivery chamber 16 in the riser 9 relative to the surroundings 17, is arranged in a sealing lower part 20 of the lantern 14. Via a separate bottom plate 21, a holding upper part 22 of the lantern 14 is supported on the seal base 20 of the lantern 14.
- a maintenance clamp 23 is arranged prior to removal of the drive clamp 18 on the polishing rod 6 in the holding shell 22 or this arranged so that they support the weight of the pump linkage (not shown), including the not visible in the figure pump rotor of the petroleum pump 3, over the polishing rod 6 on the bottom plate 21 of the holding shell 22 and from here on the seal base 20, including on the lantern flange 13 the underlying T-piece 12 and below on the Bohrlochflansch 12 guaranteed.
- a pressure relief between the upper holding part 22 and the lower sealing part 20 is achieved via the bottom plate or the bottom flange 21 of the holding upper part 22.
- the two functions of the lantern 14, namely the one hand, the sealing of the pumping chamber 16 in the riser 9 relative to the environment 17 and on the other hand supporting the weight of the pump linkage (not shown), including the not visible in the figure pump rotor of the petroleum pump 3 and the polishing rod. 6 , with removed or at least already dissolved drive terminal 18 are thus distributed to two different and optimally designed for the respective function components of the lantern 14.
