Definitions

  • the invention relates to a method according to the preamble of claim 1 and a compressor according to the preamble of claim 9.
  • Such compressors are known in the prior art in various designs (see, for example, the US 4,104,008 A ).
  • the volume to be compressed must be sealed against the cylinder tube in a reciprocating compressor.
  • the seals ideally have negligible leakage. However, if leakage occurs due to wear or damage, it will be detected in the prior art and the replacement of the seal will be initiated. For this purpose, the operation of the compressor is stopped, which is optionally switched to a redundant compressor. Afterwards, a service technician is requested, who carries out the seal replacement on site. This service is usually unpredictable and causes additional journeys and times and thus high costs. Furthermore, the operator must count on downtimes or provide for a redundancy system. The latter, however, ensures higher acquisition costs.
  • the object of the invention is to alleviate or eliminate at least individual disadvantages of the prior art.
  • the invention is particularly aimed at making the replacement of the high-pressure seal easier, faster and more cost-effective.
  • the seal replacement can be considerably simplified. In many cases, no service technician is needed for the replacement of the seal.
  • the compressor may remain operational or operational.
  • at least one replacement high-pressure seal is arranged on the magazine. If the high-pressure seal can no longer ensure the sealing of the high-pressure piston due to wear or damage, the changing device is actuated such that the magazine is brought from the first operating position to the second operating position. In this case, the high-pressure seal is moved by a functional position sealing the high-pressure piston into a waiting position remote from the high-pressure piston.
  • the replacement high-pressure seal is moved from a holding position remote from the high-pressure piston into a functional position which adjoins the high-pressure piston, in which the high-pressure piston is sealed via the replacement high-pressure seal in the second cylinder.
  • the high-pressure piston is connected fixedly or detachably to the drive piston, so that the high-pressure piston is driven via the drive piston.
  • the drive piston and the high pressure piston are designed as pressure booster (pressure converter), wherein a lower pressure of the drive medium is converted into a higher pressure of the working medium. If all (replacement) high-pressure seals are worn, the magazine can be exchanged as a whole against a corresponding magazine with unused (replacement) high-pressure seals.
  • the magazine may have a corresponding access opening.
  • the exchange of magazines on site is quick and easy.
  • the calibration and the introduction of the (replacement) high-pressure seals must be advantageous not take place on the spot, but can be prepared.
  • the service inserts for the replacement of the seals can thus be planned.
  • directional indications such as “axial,” “radial,” refer to the center axis of the high pressure piston.
  • Various embodiments are provided for transferring the magazine from the first operating position to the second operating position.
  • the magazine is displaceable in the axial direction to allow the removal of the high pressure seal from the high pressure piston.
  • the second cylinder can be immobile in the axial direction.
  • the high pressure seal abuts the outer periphery of the high pressure piston to seal the reciprocating motion of the high pressure piston.
  • the magazine can be moved axially in one direction into the first intermediate position, in which the high-pressure seal, seen in the direction of the central axis of the high-pressure piston, is arranged outside the high-pressure piston.
  • the magazine is in the moved second intermediate position in which the center axes of the replacement high-pressure seal and the high pressure piston are arranged substantially collinear.
  • the magazine is axially displaced in the other direction to seal the replacement high pressure seal on the high pressure piston.
  • the high pressure piston can in turn be coupled to the drive piston to continue the compression of the working medium.
  • the high-pressure piston is immovably arranged when moving the drive piston and the high pressure piston away from each other with a magnetic element in the direction of the central axis.
  • the magazine In the first operating position, the high-pressure seal sits sealingly on the high-pressure piston.
  • the magazine In order to free the high-pressure seal from the high-pressure piston, the magazine can be displaced together with the second cylinder axially in the one direction to the first intermediate position in which the sealing contact between the high pressure piston and the high pressure seal is released.
  • the high pressure seal is pushed on the magazine in the first intermediate position beyond one end of the high pressure piston in the axial direction, so that the high pressure seal is arranged in the axial direction outside of the high pressure piston.
  • the magazine can be brought into the second intermediate position, with which the arrangement of the replacement high-pressure seal is prepared.
  • the magazine together with the second cylinder can be axially displaced in the other direction in order to arrange the replacement high-pressure seal on the magazine sealingly on the high-pressure piston.
  • the magazine and the second cylinder for the high-pressure piston when replacing the high-pressure seal can be arranged immovable.
  • the high-pressure piston can be pushed out of the high-pressure seal on the magazine so that the movement of the magazine into the second intermediate position is released.
  • a displacement of the high-pressure piston beyond the first or second end position may be provided.
  • this is made possible by the fact that the pressure in a pressure chamber on the side facing away from the high-pressure piston side of the drive piston is lowered in comparison to the first operating position. After replacement of the replacement high-pressure seal, the pressure in the pressure chamber can be increased again to the level of the first operating position, so that the movement of the drive piston in the second operating position is limited to the first and second end positions.
  • the pressure space is preferably formed between a first piston element of the drive piston and a second piston element of the drive piston.
  • the first and the second piston element can be connected to each other via a connecting element, in particular a connecting rod, with which a maximum distance between the first piston element and the second piston element in the first and second operating position and a minimum distance between the first and second piston element in the first intermediate position is provided.
  • the high-pressure seal is arranged in the first and second operating position during compression of the working medium in each case within the receptacle on the magazine.
  • the recording on the magazine in the first operating position is free of the high pressure seal.
  • the further intake is free of the replacement high-pressure seal. Accordingly, the high-pressure seal is in the first operating position in the axial direction seen outside the recording of the magazine.
  • the replacement high-pressure seal is seen in the axial direction outside the further recording of the magazine.
  • the high-pressure seal When replacing the high-pressure seal, the high-pressure seal can first be accommodated in the receptacle on the magazine before the magazine together with the replacement high-pressure seal is moved to the second intermediate position for replacement of the replacement high-pressure seal. Finally, the replacement high-pressure seal is pushed out of the further receptacle to arrange the replacement high-pressure seal in the second operating position.
  • one of the receptacles on the magazine is always empty in order to be able to pick up a worn high-pressure seal during the exchange process.
  • the high-pressure seal and the replacement high-pressure seal are preferably displaced together with the second cylinder.
  • the high-pressure seal and the replacement high-pressure seal each have substantially the same inner and outer diameter as the second cylinder respectively.
  • the high-pressure seal In the first operating position, the high-pressure seal is preferably arranged adjacent to an axial end region of the second cylinder.
  • the replacement high-pressure seal In the second operating position, however, the replacement high-pressure seal is arranged adjacent to the axial end region of the second cylinder.
  • the high-pressure seal viewed in the axial direction, is arranged between the second cylinder and a pressure part. The pressure part is displaceably mounted in the axial direction by means of the changing device.
  • the pressure part is axially displaced via the changing device in one direction, so that the high-pressure seal is displaced together with the second cylinder. Accordingly, the second cylinder is displaced in the other direction to push out the replacement high-pressure seal from the further recording.
  • the pressure part is taken along.
  • the displacement of the pressure part in one direction or the displacement of the second cylinder in the other direction is effected via the drive, for example a pneumatic drive, the changing device.
  • the magazine for transferring from the first intermediate position to the second intermediate position can be pivoted on the one hand about a substantially parallel to the central axis of the high-pressure piston pivot axis or on the other hand displaced substantially in the direction perpendicular to the central axis of the high-pressure piston.
  • a sensor device for detecting a leakage of the working medium is provided.
  • the sensor device may be formed according to the prior art. For example, a pressure increase in a normally pressureless leakage line can be detected in connection with the high pressure seal. Furthermore, a gas measurement in the leakage line can be made.
  • a control device is connected on the one hand to the sensor device and on the other hand to the exchange device in order to transfer the magazine from the first operating position into the second operating position upon detection of a leakage of the working medium.
  • the changing device for transferring the magazine from the first operating position to a first intermediate position is adapted to displace the magazine together with the high-pressure seal arranged in the receptacle substantially in the direction of the central axis of the high-pressure piston relative to the second cylinder.
  • a tensioning device for releasably coupling the high-pressure piston to the drive piston is preferably provided.
  • the high-pressure piston moves together with the drive piston.
  • the high-pressure piston is decoupled from the movement of the drive piston.
  • the drive piston and the high-pressure piston can be fixedly connected to each other.
  • the high-pressure piston is arranged in the first intermediate position of the magazine in the dissolved and spaced from the drive piston state. It is particularly preferred if, in the first intermediate position of the magazine, the high-pressure piston is arranged in the first end position and the drive piston is arranged in the second end position moved away therefrom. In this embodiment, the high-pressure piston and the drive piston in the first intermediate position are maximally remote from each other, so that sufficient space for exemption of the high-pressure seal is present.
