Definitions

  • the invention relates to an oil-lubricated rotary vane vacuum pump with a rotary vane unit, comprising a rotary vane chamber and a rotary vane rotor, and with an oil separating and reprocessing device, whereby in the oil separating and reprocessing device there is a separation of oil and gas by means of the mentioned Devices one or more monitoring and / or maintenance devices are provided and the oil separation and reprocessing device is accommodated in an oil separation and reprocessing housing, with side walls, a bottom wall, a top wall and end walls, the side walls extending transversely to a plane of rotation of the rotary valve rotor and specify a longitudinal extension of the oil separator and reprocessing housing.
  • Oil-lubricated rotary vane vacuum pumps of the type in question are known.
  • This is usually a rotary valve fan with a rotary valve housing which forms a rotary valve chamber and which rotary valve chamber is designed in the form of a cylindrical bore.
  • the rotary vane rotor is usually cylindrical, with slides which are arranged to be displaceable in slots of the rotor.
  • the slots in the rotor can be aligned strictly radially with respect to a cross section through the rotor or they can also run at an acute angle to a radial.
  • the rotor is preferably supported in the area of the side covers closing off the rotary valve housing at each end.
  • the rotor When the vacuum pump is operating, the rotor rotates radially offset to the central axis of the rotary valve housing. This results in closed chambers, separated by the essentially radially displaceable slides, the size of which changes during one rotation of the rotor. The change in size results in pressure differences between the individual chambers and thus between the inlet side and the outlet side of the pump.
  • the oil is pumped from the last chamber into the outlet together with the pumped gas.
  • the oil is heated.
  • the oil can also become contaminated as a result of contact with the pumped medium or change as a result of possible chemical reactions. This results in a preferred preparation of the oil after it has left the fan area. In this regard, it is known to let the oil run through the device in a cycle.
  • the oil treatment process can essentially be carried out in three sub-processes.
  • oil and gas are separated, possibly in several stages.

  • This housing can thus be made simple.
  • the top wall and the bottom wall, more preferably also at least one external side wall, can be designed without any preparations for the arrangement of relevant devices.
  • the float device is a control for the flow from the upper to the lower chamber. It is influenced in particular by an oil level that is established in the upper chamber.

  • the housing section 27 resulting under the passage opening 26 in the area of the lower chamber 21 serves in the manner of an oil pan in which an oil sump collects. An oil collecting container is thus formed in the lower chamber 21.
  • the lower chamber 21 also forms a flow path with a flow a oriented towards the longitudinal alignment of the housing. This flow a is directed in the direction of the rear end wall 19.
  • the inner side of the end wall 19 is designed to deflect the flow from the lower chamber 21 into the upper chamber 22, in which the flow path formed in the upper chamber 22 allows a flow b opposite to the flow a of the lower chamber 21.

This directs the sound towards the floor, which leads to a reduction in noise pollution.
  • the gas outlet connection 35 is preferably arranged rotatably on the maintenance cover 33, so that the exhaust air can optionally also be deflected to the side or upwards, for example.
  • the deflection cap 36 can be exchanged, for example with a gas outlet nozzle for connecting a silencer or a continuation element.
  • a maintenance cover 33 with deflection cap 36 can be exchanged for a maintenance cover 33 for connecting, for example, external piping.
