Definitions
- Sealing arrangement for sealing a piston rod of a reciprocating compressor
- the subject invention relates to a sealing arrangement for sealing a reciprocating piston rod of a reciprocating compressor with a first and second sealing element, which are arranged axially spaced in a recess of the sealing arrangement, wherein the sealing elements arranged in each case at one axial end of the recess and on the piston rod fitting are and in the sealing arrangement, a supply line for a sealing medium is provided, which is connected to the recess.
- seals between a reciprocating piston rod, e.g. a piston compressor, and a stationary machine part for sealing a high pressure space, e.g. the working pressure in the cylinder of the compressor, against a low pressure noise, e.g. the atmospheric pressure in the crankcase of the compressor are usually carried out as gaskets.
- a sealing packing comprises a plurality of packing rings or packing ring combinations arranged axially one behind the other. Most commonly, combinations of a radially cut and a tangentially cut packing ring are used, such as e.g. from EP 1 146 264 A2.
- segmented ring designs in which a packing ring is composed of a plurality of ring segments are also used, such as e.g. from US 4 350 349 A known.
- seals are not 100% dense systems, but always have a certain amount of leakage that escapes through the seal.
- a sealing medium eg oil or another suitable liquid
- the ambient pressure eg the working pressure in the cylinder of a compressor
- a working medium such as a gas or air
- an ionic liquid as the sealing medium
- sealing elements are arranged spaced from the radial end of the recess in the radial direction, so that the sealing medium engages axially and on the radially outer peripheral surface of the first and second sealing elements. Due to the radial spacing from the radial end of the recess, it is ensured that the sealing elements can move freely with them (apart from any frictional forces) in the event of a possible transverse movement of the piston rod, without the sealing effect being lost.
- the recesses in the sealing arrangement are formed by two L-shaped chamber discs, which are arranged axially adjacent to each other, wherein in each case a sealing element is arranged in the recess formed by the L-shaped chamber disc.
- Such L-shaped chamber discs may, e.g. by continuous bolts, very easy to assemble into a compact sealing arrangement.
- the two L-shaped chamber discs are arranged in the same direction, so that the radial leg of an L-shaped chamber disc is arranged between the two sealing elements and the two sealing elements are arranged axially spaced from this radial leg.
- the supply line can be easily arranged in this central radial leg.
- sealing elements are rigid, segmented or cut packing ring or packing ring combinations, or hydraulic seals in question.
- a high degree of flexibility can be achieved and the sealing arrangement can be optimally adapted to the particular specific application and the prevailing conditions.
- a hydraulic sealing ring this is advantageously arranged axially fitting in a rigid L-shaped support ring, wherein the support ring radially spaced from the radial end of the recess remains.
- a Volunteerabêtinheit is arranged between the support ring and hydraulic sealing ring.
- Such an arrangement is compact and seals both the main sealing surface (here to the piston rod), as well as secondary sealing surfaces safely.
- a third sealing element is arranged, which is designed as a packing ring or packing ring combination, on the one hand the ingress of dirt is prevented in the seal, and on the other hand, in the case of failure of the adjacent Sealing element by the third sealing element still maintained a certain sealing effect, whereby at least an undesirable unhindered leakage of sealing medium can be prevented. This increases the reliability of the sealing arrangement.
- a feed line opens into a gap formed between the first sealing element and the third sealing element, which feed line is connected to the suction pressure of the reciprocating compressor during operation, so that the suction pressure acts in this intermediate space. This ensures that this gap is maintained at suction pressure, whereby the first sealing element only has to seal against the (low) constant suction pressure.
- the (high) dynamic working pressure is reduced by the third sealing element. This facilitates the structural design of the sealing arrangement and reduces the requirements on the first sealing element, especially in terms of required life considerably. In addition, this of course achieves advantageous that the operating pressure of the sealing medium can be significantly reduced and consequently can be used in all systems involved with lower pressures.
- the pressure difference acting on the second sealing element can be reduced if, at a second axial end of the sealing arrangement in a fourth recess of the sealing arrangement adjacent to the second sealing element, a fourth sealing element is arranged, which is designed as a packing ring or packing ring combination or as a hydraulic sealing ring then the pressure difference is split between the second and fourth sealing elements.
- This measure reduces the requirements for the second sealing element, especially in terms of required life.
- this increases the reliability of the sealing arrangement, since the fourth sealing element still maintains a certain sealing effect, if the second sealing element should fail.
- a fifth sealing element which is designed as a scraper ring, can be arranged on a second axial end of the sealing arrangement. This is still stripped on the piston rod adhesive sealing medium, which can be recycled to the sealing medium circuit.
- the operational reliability can also be increased by arranging between the first sealing element and the second sealing element in a further sixth recess of the sealing arrangement a further sixth sealing element, which is designed as a packing ring or packing ring combination or as a hydraulic sealing ring, and this radially in use spaced from the piston rod is arranged.
- a sealing element is ineffective in normal operation, but is activated if the first sealing element should fail, since then the pressure to be sealed is applied to the sixth sealing element.
- another seventh sealing element may be provided between the first sealing element and the third sealing element in a further seventh recess of the sealing arrangement, which is designed as a scraper ring to strip off any sealing medium adhering to the piston rod and to return it to the sealing medium circuit.
- a leak-free sealing arrangement can be created.
- the scraper ring can be easily held differentiated rucklos when the pressure acting before the scraper ring pressure is connected to the seventh recess.
- Fig. 1 is a gas-tight seal according to the invention.
- Fig. 2 to 6 further advantageous embodiments of a gas-tight seal.

- the sealing arrangement 1 is arranged in a stationary housing part 2 of the compressor and seals between this housing part 2 and the moving piston rod 3.
- the sealing arrangement 1 comprises two L-shaped chamber disks 4, 5, which are separated axially by a separating disk 6 in the exemplary embodiment shown.
- the L-shaped chamber discs 4, 5 and the cutting disc 6 are arranged axially adjacent to each other and radially spaced from the piston rod 3, to prevent a rubbing of the piston rod 3 to the chamber discs 4, 5 and to a mobility of the piston rod 3 transverse to the lifting movement ( indicated by the double arrow).
- the cutting disc 6 but also be omitted. But they are too
- a flange can also be provided radially on the outside, by means of which the sealing arrangement 1 can be fastened to the housing part 2.
- the chamber discs 4, 5 and optionally the cutting disc 6 can be held together in a known manner by a continuous bolt. This arrangement results between the L-shaped chamber discs 4, 5, optionally the cutting disc 6 and the piston rod 3, a recess 10.
- a first and second sealing element 8, 9 are arranged, wherein the sealing elements 8, 9 by the acting Pressure of a supplied into the recess 10 sealing medium respectively at the axial ends of the recess 10, so the radial limbs of the L-shaped chamber discs 4, 5, rest and are arranged axially separated from each other (the orientations "axially” and “radially” are on the orientation of the piston rod 3 related).
- the first and second sealing element 8, 9 are spaced apart radially from the chamber discs 4, 5, that is, from the axial limbs of the chamber discs 4, 5, and lie radially inwardly against the sealing surface on the piston rod 3.
- a supply line 7 is further provided, which is connected to the recess 10 and via which a sealing medium, such as an oil, under a pressure p 0l ⁇ , which is greater than the pressure to be sealed p d , in the recess 10th can be supplied.
- a sealing medium such as an oil
- p 0l ⁇ > p d m a x
- the pressure of the sealing medium is dynamically reasonable to the pressure of the working medium fit, so always have p o, ⁇ > p d.
- the sealing medium is thus enclosed by the sealing elements 8, 9 in the recess 10 and acts radially outward and axially on the sealing elements 8, 9, which are thus pressed radially inwardly to the piston rod 3 and axially to the chamber discs 4, 5 and thus seal ,
- the sealing elements 8, 9 are moved without affecting the sealing effect.
- sealing elements 8, 9 either known hydraulic sealing rings, such as a lip pendulum ring or a compact sealing ring, with a voltage applied to the piston rod 3 sealing lip, or even well-known rigid, cut or segmented packing rings or packing ring combinations, such as a combination from a radially and tangentially cut packing ring can be used.
- hydraulic sealing rings can also be designed in such a way that sealing medium, which is pressed through the sealing lip during a stroke, is "sucked back" through the sealing lip during the counterstroke, so that in total there is no leakage of sealing medium through the hydraulic sealing ring Packing rings or packing ring combinations usually there is a slight leakage of sealing medium through the seal, which is usually not a problem.
- packing rings usually also a standstill leakage, while a hydraulic sealing ring seals by the sealing medium pressure even at a standstill, at least as long as the sealing medium pressure is maintained.
- Fig. 2 is a further advantageous embodiment of the sealing arrangement according to the invention
- the sealing arrangement 1 here comprises a plurality of successively arranged L-shaped chamber discs 20, 21, 22, 23, 24, wherein the L-shaped chamber discs 20, 21, 22, 23, 24 are aligned here all rectified, whereby the axial legs all in the same Direction.
- this seal assembly 1 in the axial direction by an end plate 25, which serves as a flange for attachment in the housing part
- the actual sealing takes place by the sealing elements 8, 9, which are arranged in the recesses 31, 32 formed by three adjacent chamber discs 21, 22, 23, as described above for Fig. 1.
- the supply line 7 for the sealing medium can be performed by the radial leg of an L-shaped chamber disc 22.
- a sealing element 8, 9, shown in detail in Fig. 3, here in each case comprises an L-shaped rigid support ring 36 which abuts the radial leg of the axially outer chamber discs 21, 23 and radially spaced from the axial leg of the axially outer chamber discs 21, 23rd is arranged.
- At the radial leg of the support ring 36 is axially on a hydraulic sealing ring 38 at.
- a resilient Mauabêtinheit 39 for example, an O-ring can be further arranged.
- This secondary sealing unit 39 is used for sealing the secondary sealing surfaces, here for example between the radial leg of the support ring 36 and the hydraulic sealing ring 38, but also for pressing the hydraulic sealing ring 38 against the sealing surface of the piston rod 3.
- the use of an O-ring as secondary sealing unit 39 Particularly advantageous because an elastic, non-compressible O-ring, the upcoming sealing medium pressure in a radial contact force with which the sealing ring 38 is pressed against the piston rod 3, converts.
- sealing unit 39 may also be omitted, in this case, the hydraulic sealing ring 38 would also abut the axial leg of the support ring 36 and seal this secondary sealing surface.
- the L-shaped support ring 36, optionally the Mauabêtinheit 39 and the hydraulic sealing ring 38 are axially spaced from the central radial leg of the chamber disc 22, so that the sealing medium, the sealing element 8, 9 for sealing axially against the respective radial leg of the chamber disc 21, 23 can press ,
- the sealing element 8, 9, here the arrangement of L-shaped support ring 36, optionally elastic support ring 39 and hydraulic sealing ring 38 while maintaining the sealing effect with the piston rod 3 moves.
- the third sealing element 1 1 can also be designed as a rigid or segmented packing ring or as a packing ring combination. The high working pressure p d of the working medium thus acts on this third sealing element 11 in the operational use of the sealing arrangement 1.
- This third sealing element 11 essentially serves, on the one hand, to prevent the penetration of dirt into the actual seal formed by the two sealing elements 8, 9 and, on the other hand, in the case of failure of the sealing element 8 by the third sealing element 11, still maintains a certain sealing effect to be able to, whereby at least an unhindered leakage of sealing medium into the cylinder chamber can be prevented.
- a fourth sealing element 14 here again a combination of an L-shaped support ring, optionally Mauab Whyinheit and hydraulic sealing ring as described above, respectively.
- this sealing element 14 on the one hand, a division of the effective pressure difference between the pressure p o , ⁇ the sealing medium and acting in the crankcase atmospheric pressure p a t on the sealing elements 9 and 14 is achieved, and on the other hand, this sealing element 14 again forms a certain security, if the sealing element 9 should fail.
- a hydraulic sealing ring but can be used as a sealing element 14 in turn a rigid, cut or segmented packing ring or a packing ring combination of such packing rings.
- a fifth sealing element 15 here a scraper ring 17, which is arranged in a recess 34 of the last L-shaped chamber disc 24, completed.
- the differential pressure scraper ring 17 is arranged in an L-shaped rigid support ring 16 and can also by Springs or other bias are axially pressed against the support ring 16 to prevent axial reciprocation of the scraper ring 17 ..
- the scraper ring 17 excess, adhering to the piston rod 3 sealing medium ge of the Kolbestan- 3 is removed.
- This excess sealing medium can be collected in the recess 34 and discharged from there by appropriate discharges and fed to a sealing medium reservoir.
- the fifth sealing element 15 prevents penetration of dirt into the actual seal formed by the two sealing elements 8, 9 and optionally sealing element 14.
- the third, fourth and fifth sealing element 1 1, 14, 15 are optional in the sealing arrangement 1 and can be used according to needs and application in any combination.
- FIGS. 4 to 6 A further development of the invention is shown in FIGS. 4 to 6.
- the cylinder is held in front of the first sealing element 8, the pressure on the suction pressure p s of the compressor.
- This has the advantage that only the (low) static suction pressure p s has to be sealed by the first and second sealing elements 8, 9.
- the (high) dynamic cylinder pressure p d -p s is reduced by a sealing element 11 located in front of it.
- the necessary pressure p 0l ⁇ the sealing medium can therefore be lowered accordingly far.
- At the individual sealing elements 8, 9 is therefore also a lower pressure difference, whereby the requirements for the sealing elements 8, 9 can be reduced.
- compressor applications typically require 8,000 hours of operation without failure for the seal assembly 1.
- hydraulic sealing rings are unsuitable as sealing elements 8, 9, since they would not reach the required service life under such operating conditions.
- the first and second sealing element 8, 9 formed by two hydraulic sealing rings, as described for Fig. 1.
- Cylinder side before and axially spaced from the first sealing element 8 is a third sealing element 11, here in the form of a packing ring combination arranged.
- the third sealing element 1 1 can also be designed as a rigid or segmented packing ring or as a packing ring combination. Since the first sealing element 8 and the third sealing element 1 1 are arranged axially spaced from each other, between these sealing elements 8, 1 1, a gap 49, which is bounded radially here by the first chamber disc 21.
- the pressure via a supply line 40 in the first chamber disc 21, via a supply line 45 with the suction pressure p s , for example with the suction line 60 of the compressor is connected, held at suction pressure p s .
- the static suction pressure p s acts in the intermediate space 49 between the first sealing element 8 and third sealing element 11 thus the static suction pressure p s acts.
- the sealing medium thus only needs to be sealed off from the suction pressure p s .
- the dynamic pressure difference p d - p s is degraded by the third sealing element 11, here a packing ring combination, which is substantially less pressure sensitive than a hydraulic sealing ring. With regard to the effective pressures, therefore, only more p o , ⁇ > ps must be satisfied.
- the fifth sealing element 15 is not absolutely necessary, especially when hydraulic sealing rings with "back suction" are used, as described above. If present, the fifth sealing element 15 (scraper ring) removes the sealing medium adhering to the piston rod 3, thus removing the sealing medium
- the retained sealing medium is supplied to a sealing medium reservoir 42 via a sealing medium line 41.
- sealing medium is supplied to the supply 7 at a pressure p 0l by means of a pump 43 via a supply line 44 , in particular when using a packing ring or a packing ring combination as the first sealing element 8, must be regularly refilled into the sealing medium reservoir.
- packing ring combinations are used as the first and second sealing elements 8, 9 instead of hydraulic sealing rings. This always results in a certain sealing medium leakage into the cylinder chamber and into the crankcase, since such a packing ring combination is never completely tight. Otherwise, between the first and second sealing element 8, 9, in the recess 31 a of a further sixth chamber disc 21 a another sixth sealing element 8 a, here for example a hydraulic sealing ring (but could also be a packing ring or a packing ring combination) hen provided , However, this sixth sealing element 8a is installed with oversize, ie it is initially not radially inwardly sealingly on the piston rod 3, and is therefore not activated for the time being.
- the suction pressure p s suddenly acts on one side of the sixth sealing element 8a and the sealing medium pressure p1l on the other side, and the sixth sealing element 8a can be designed such that it is activated in this case the pressure of the sealing medium p o , ⁇ sealing against the piston rod 3 is pressed.
- the sixth sealing element 8a thus serves to ensure and maintain the sealing effect. kung in case of failure of the first sealing element 8a.
- a sixth sealing element 8a could also be used in a sealing arrangement as shown in FIG.
- a scraper ring can also be provided on the cylinder side, as shown in FIG.
- a seventh sealing element 50 in the form of a scraper ring is arranged between the first sealing element 8 and the third sealing element 1 1 in a further seventh chamber disk 51.
- the sealing medium removed by the scraper ring from the piston rod 3 is removed via a discharge line 48 from the recess 52 formed by the seventh chamber disk 51.
- the discharge line 48 opens into a second sealing medium reservoir 46, which is held at suction pressure p s , as indicated in FIG.
- the second sealing medium reservoir 46 may be connected to the first sealing medium reservoir 42 via a throttle 53 and a connecting line 47.
- the throttle 53 is necessary because the first sealing medium reservoir 42, as a rule, for example, is held by a vent to atmospheric pressure p at, and otherwise the sealing medium would freely flow into the first sealing medium reservoir 42nd
- a sol- rather scraper ring could also be used in a sealing arrangement 1 according to FIG. 2. In this case, the scraper ring could be held without differential pressure, by the force acting in front of the scraper ring pressure through corresponding connecting holes in the scraper ring receiving recess is guided.
