Definitions

  • the present invention relates to a method according to Preamble of claim 1.
  • Heat exchanger provided, wherein the heat exchanger in Housing via a first line system to a heating unit and the heat exchanger in the shaft via a second Line system are connected to a cooling unit.
  • Heating unit is the housing, which in operation to the Environment gives off heat, at a given temperature held.
  • cooling unit is the by friction between shaft and bearing arising and released Energy compensated, causing a local overheating of the Good to be avoided.
  • Such a temperature stabilization system is known from German patent application with the publication number DE 37 30 991 A1 discloses, wherein the to be cooled or heated housing parts via a piping system in Parallel circuit supplied with a temperature control medium become.
  • the present invention is therefore the task to provide a method that mentioned above Disadvantages not.
  • the invention has the following advantages: from the tempering initially the waves and / or the Slide bearing and then the at least one housing part of the Medium for the purpose of stabilizing the temperature are flowed through, which by the in the plain bearing rotating shaft generated waste heat through the medium in the Housing transported, i. the shaft and the housing act like a temperature aggregate, bringing the system is greatly simplified, which is particularly in lower costs manifested.
  • Fig. 1 shows - in a schematic representation - a known System for stabilizing the temperature of one with a Gear pump funded conveyed.
  • the gear pump consists of at least one housing part G, in which in particular, two waves W are included, each at least in one, preferably in two plain bearings L are rotatably mounted.
  • gear pumps are particularly suitable for conveying highly viscous liquids such as for example, polymer melts. It is to Make sure that the temperature of the conveyed material is as high as possible stable corresponds to a certain value, in which neither one Decomposition - which occurs at too high temperatures - still a blockage of the gear pump - e.g. by setting the slide bearing - enter through a viscous conveyed material can, what at too low temperatures of the transported material is possible.
  • These were in a known manner in the housing G and in the shaft W of the gear pump heat exchanger provided via the supply systems ZS1 and ZS2 each with Temperingaggregaten T1 and T2 are connected.
  • the Temperieraggregaten T1 and T2 is a medium M on a desired temperature heated or cooled and with Help of supply systems ZS1 and ZS2 to the heat exchanger in the shaft W or in the housing G supplied.
  • the known system has the disadvantage that for the Separate supply systems ZS1 and ZS2 also two Temperingaggregate T1 and T2 are provided.
  • the advantage the independent temperature setting for shaft W and Housing G are extremely expensive for the Temperingaggregate T1 and T2 opposite.
  • Figs. 2 to 4 are different Devices for adjusting and stabilizing the Temperature of the transported material shown. All have three variants a single tempering TA to which the supply systems ZS to the heat exchangers in the housing G or in the shaft W in different ways are connected.
  • Fig. 2 is a known system shown; in which the heat exchanger parallel to the Temperieraggregat TA are connected, that is, that the Medium M in the supply systems ZS before the corresponding heat exchanger the same temperature having.
  • Fig. 4 is an inventive embodiment shown, in which a series connection of the two Heat exchanger is provided, because first, the medium M - starting from the temperature control unit TA - through the Heat exchanger in the shaft and then through the Heat exchanger in the housing G out.
  • the medium M - starting from the temperature control unit TA - through the Heat exchanger in the shaft and then through the Heat exchanger in the housing G out.
  • the heat generated in the shaft W through the medium M is transported into the housing G, i. Shaft W and housing G act like a temperature control unit.
