Definitions

  • the invention relates to a rotary compressor with an axial Direction of conveyance from top to bottom, especially in screw-spindle design, with a cooling fluid flowing through it Cooling channels for the motors, bearings and sensors and one Cooling device for the scooping area.
  • Such a known rotary piston compressor (DE 19522559 A1) has two screw spindles that mesh and driven synchronously by motors. Angle of rotation and Rotational speeds of the two screw spindles or rotors are detected by sensors. The engines will electronically synchronized with the signals from these sensors.
  • Motors, bearings and sensors are cooled, cooling to the lowest possible temperatures, e.g. B. 20 ° C take place should, of course, not be cooled so far may cause condensation.
  • the creative space the is heated by the compression of the pumped medium, must also be cooled.
  • the scoop should be open a higher temperature of, for example, 60 ° C can be cooled, to prevent the pumped medium from condensing.
  • cooling fluid flowing through cooling channels flows.
  • the cooling of the scoop chamber takes place in the first Line through internal cooling of the screw spindles, however is also contemplated in one embodiment that Cool the housing of the pump chamber.
  • the corresponding cooling fluid but must have a higher temperature than that Cooling fluid for the motors, bearings and sensors, making two separate cooling circuits are required. Should the rotary lobe compressor maintenance or repair requires two Cooling circuits are separated and emptied.
  • the cooling system is therefore complex and requires considerable work when disassembling the rotary lobe compressor.
  • Such a type of cooling device for a screw vacuum pump with internal engine and bearing cooling lines and external cooling rooms in the Housing is known from BE 19745616 A.
  • the object of the invention is to create a Rotary lobe compressor with which in a particularly simple way a cooling of the motors, bearings and sensors on proportionately low temperature and cooling of the delivery space to a considerably higher temperature is possible, whereby at the same time a stronger cooling of the scooping area on the Pressure side than on the suction side.
  • the housing of the scooping chamber has a closed annular space, that is partially filled with a liquid that is cooled by the cooling fluid over heat exchanger surfaces.
  • the scoop is therefore cooled by a liquid that is located in a closed annulus.
  • This annulus extends in an advantageous embodiment over the entire height of the housing of the scooping chamber.
  • the one in it The liquid contained in the motor is cooled by the cooling fluid Cooled bearings and sensors.
  • the flow rate can and the size of the heat exchanger surfaces so chosen that the motors, bearings and sensors are on be cooled about 20 ° C, the housing of the scoop but is cooled to a temperature of about 60 ° C.
  • There the annulus is only partially filled with liquid in the upper area, d. H. the suction area, the cooling less effective, which corresponds to the fact that less cooled here must become.
  • the annulus since the annulus only partially filled with liquid, the same when heated expand. When removing the housing, the liquid is needed not to be drained in the annulus, but remains in this. It only needs the circuit for the cooling fluid for the motors, bearings and sensors separately and under May be partially emptied.
  • the annulus has a cooling coil that is flowed through by the cooling fluid.
  • the liquid in the annular space is expediently a water-glycol mixture, through which good cooling can be achieved can, but where there is no risk of freezing, when the pump is not used at low temperatures.
  • Cooling water is expediently used as the cooling fluid.
  • the cooling fluid first the cooling channels for motors, bearings and sensors and then flows through the cooling coil.
  • the cooling channels and the annular space are advantageously closed, i.e. they have no connection to the creative space, so that a seal otherwise required here - with their known Problems - is not required.
  • the rotary compressor has a motor housing 1 and Housing 2 of the scoop 3.
  • the screw spindles 4 are rotated synchronously by motors 8.
  • an electronic synchronization takes place so that the screw spindles 4 do not touch can. So with adverse operating conditions and bad or completely failing synchronization interlocking screw spindles 4 are not touching intermeshing gears 10 on the shafts 5 below provided, the angular play is smaller than that of the screw spindles 4th
  • the motors 8, bearings 6, 7 and sensors 9 are cooled by water cooled, which is passed through cooling channels 12 and enters these channels 12 through an opening 13 and out of a Opening 14 leaves the cooling channels 12 again.
  • the housing 2 of the scooping chamber 3 has an annular space 15, which is filled to a level 16 with a water-glycol mixture is.
  • a cooling coil is also located in the annular space 15 18, which is cooled by the cooling water that the Motor housing 1 leaves through the opening 14 and through a Line 17 is passed into the cooling coil 18 and then flows out through line 19 again.
  • the housing 2 is thus cooled by the liquid in the annular space 15, which in turn is cooled by the cooling water that the motors first 8, bearings 6, 7 and sensors 9 had cooled. Because the annulus 15 is only filled with coolant up to level 16 these expand when heated.
  • the creative space cooled more on the (lower) pressure side than on the (upper) suction side. Because the coolants are in closed Rooms 12, 15 are located, a seal against the scoop 3 is not required. There are therefore the known Problems of such seals avoided.
