Definitions

  • the invention relates to a rotor compressor, in particular a screw rotor compressor with lubricant supply to and lubricant drainage from the shaft bearings, each rotor shaft between the shaft bearing and the rotor receiving work space of the compressor from an annular drainage space for removing the lubricant and gas leakage and from a sealing arrangement sealing the shaft is surrounded.
  • a compressor of this type in which the annular drainage space is part of a complex sealing arrangement of great length, which has the purpose of sucking in unfiltered outside air into the working space of the compressor and the leakage of lubricant. and to avoid coolant from the compressor working space along the shaft.
  • the sealing arrangement has, in addition to the drainage space, further annular spaces, one of which is acted upon as a barrier pressure space by a compressed gas source, in particular by the compressor outlet.
  • the annular drainage space opens to the outside, and this means that the amounts of gas entering the drainage space from the barrier pressure space are lost.
  • the invention has for its object to provide a compressor of the type mentioned which can also be used, in particular, for refrigerant compression and which manages with a very simple, cheap and space-saving sealing arrangement against lubricant and gas leakage.
  • the lubricant is returned directly from the collecting spaces into the suction or working space of the cylinder.
  • the collecting spaces or a channel connecting them are connected to the suction space or work space through openings.
  • the lubricant is carried by the gas flow through the working chamber of the cylinder and excreted in a separator connected to the pressure side of the compressor.
  • Another embodiment of the invention is more advantageous for these applications, in which the collecting spaces and / or a channel connecting them are connected to a separating container, the gas space of which is connected a gas line is connected to the suction side of the compressor and its sump via a lubricant line to the lubricant circuit.
  • a second circuit for a coolant and lubricant can be provided, which is supplied to the working space of the compressor and is separated from the compressed gas stream by a separator connected to the pressure side of the compressor.
  • a connecting line with a valve can be provided between the separator and the separating container of the lubricant circuit, which valve can be controlled by a level switch on the separating container.
  • the compressor has a housing 10, in the working space 12 of which two rotors 14 are mounted next to one another, which engage in one another with helically arranged ribs and grooves. Only one of these rotors 14 is visible in the drawing.
  • the shaft 16 of the rotor is supported at both ends by means of radial sliding bearings 18 and also at the end on the pressure side by means of an axial roller bearing 20.
  • the shaft of one rotor, the main rotor is driven by a drive (not shown), and the main rotor drives the secondary rotor by direct meshing engagement or also by means of a synchronous gear (not shown).
  • the gas to be compressed in particular a refrigerant such as difluoromonochloromethane, which in this case is under the evaporator pressure, is sucked in via the suction line 22 and the suction nozzle 24, compressed in the working space 12 by the rotors 14 and via the pressure nozzle 26 and the pressure line 20 as
  • the separator and storage container serving pressure container 30 is supplied, from where it reaches the consumer via the separating filter 32 and the pipeline 34, and to the condenser in the case of refrigerants.
  • oil or another liquid suitable as a coolant, sealant and lubricant which is fed to the working space 12 by means of the line 36 via a cooler 38, a throttle element 40 and the housing bore 42 in order to close the rotors cool, seal against each other and against the housing and lubricate on their meshing flanks.
  • This oil is discharged together with the compressed gas stream via the pressure port 26 and the pressure line 28 and separated from the gas stream in the container 30 and returned to the sump 44.
  • oil is removed from a closed reservoir 46 via a pump 48 and a cooler 50 and fed to the lubricant bores of the bearings 18 via the line 52 and the housing channels 54, 56.
  • the oil enters the bearing gap 1 in both axial directions.
  • a part of the oil passes from the bearing gap directly into the oil collecting spaces 56, 58, which are connected to one another by a longitudinal channel 60 in the housing 10.
  • the portion of the oil which occurs in the direction of the working space passes from the respective bearing 18 into an annular oil collecting groove 62, which is arranged as a drainage space between each bearing 18 and a sealing element 64 and is connected to the associated oil collecting space 56 and 58 by a channel 66 in each case is.
  • the oil collecting space 56 is connected to the reservoir 46 via an outlet channel 68.
  • the gas space of the reservoir 46 is also connected to the suction line 22 via a compensating line 70.
  • the reservoir 46, the spaces 56, 58 and the oil collecting grooves 62 are under the low suction pressure of the compressor.
  • the oil collecting groove 62 which is under low pressure, is arranged between each bearing 18 and the working space 12 and effectively causes a leakage of oil from the bearing 18 to the working space 12 or vice versa, a leakage of gas from the working space 12 to the bearing 18 largely prevented.
  • the additional sealing elements 64 are therefore not particularly demanding, it can be simple and very short elements such. B. act short labyrinths or swim rings. These can also be supplied with oil and lubricant pressure through appropriate housing bores, as shown at 72 for the pressure-side sealing element.
  • the oil therein can only contain relatively small amounts of a soluble gas, e.g. B. refrigerant, dissolved.
  • a soluble gas e.g. B. refrigerant
  • the corresponding proportion in the reservoir 46 at a pressure of z. B. 5 bar and a temperature of 70 ° C significantly less than 5%, which practically does not affect the viscosity of the oil.
  • a level switch 74 with lower and upper limit contact controls on the one hand a solenoid valve 76, which connects the line 36 to the reservoir 46, and also a solenoid valve 78, which connects the line 52 to the suction line 22 of the compressor.
  • the solenoid valve 76 is opened and oil can get into the container 46 from the pressure container 30. If the oil level in the container 46 rises excessively, the valve 78 opens and excess oil from the container 46 enters the suction line and from there with the gas through the compressor into the reservoir pressure container 30.
  • Fig. 2 shows a simplified embodiment for those applications in which there is no risk of a reduction in the viscosity of the oil due to dissolved gas due to low working pressures or gases not soluble in oil.
  • the same compressor design as in Fig. 1 can be used without structural changes.
  • the reservoir 46 of FIG. 1 and the associated lines and the like are omitted and the outlet opening 68 of the oil collecting space 56, which is no longer required, is closed with a stopper 80.
  • one of two bores 82, 84 is optionally opened, which connect the longitudinal channel 60 to the intake port 24 or the working chamber 12 of the compressor and of which the other bore or, when used according to FIG. 1, both bores with suitable ones Stopper 86 are closed.
  • the resulting differential pressure between the pressure container 30 and the lubrication or injection points on the compressor is sufficient to the compressor to supply with oil without fear of gas breakthrough to the bearings due to the relatively low lubricant pressure in the bearing.
