Definitions
- the present invention relates to a method according to the Preamble of claim 1.
- Gear pump lubricated for the conveyance of materials The temperature of the material being conveyed is higher for polymers This is important because the viscosity increases when the temperature is too low is high and at too high a temperature Decomposition phenomena can occur. Therefore tries the temperature of the fluid in one to hold certain area. This enables that the operating window of the gear pump is considerable can be expanded.
- the Gear pump and in the shaft in a known manner Heat exchanger provided, the heat exchanger in Housing via a first line system to a heating unit and the heat exchanger in the shaft via a second one Line system are connected to a cooling device.
- the heating unit is the housing that is in operation at the Environment emits heat at a predetermined temperature held.
- the cooling unit the friction created and released between shaft and bearing Energy compensates, which causes local overheating of the Goods to be conveyed should be avoided.
- the present invention is therefore based on the object based on specifying a method mentioned above Does not have disadvantages.
- the invention has the following advantages: Stabilization of temperature in gear pumps Temperature control unit is used, both on the Heat exchanger in the shaft and / or in the plain bearing as well is connected to the heat exchanger in the housing the system considerably simplified, which is particularly evident in manifested lower costs.
- Fig. 1 shows - in a schematic representation - a known System for stabilizing the temperature of one with one Gear pump conveyed material.
- the gear pump consists of at least one housing part G in which in particular two waves W are contained, each at least in one, preferably in two plain bearings L. are rotatably mounted.
- the Structure of gear pumps is, for example, based on the Maag paperback, 2nd edition, 1985, pages 279 ff.
- gear pumps are particularly suitable for pumping highly viscous liquids such as for example of polymer melts. It is about make sure that the temperature of the material being conveyed is as possible stably corresponds to a certain value at which neither Decomposition - which occurs when the temperature is too high - still a blockage of the gear pump - e.g. by fixing the plain bearing - enter through a viscous product can what happens when the temperature of the material being conveyed is too low is possible.
- each with supply systems ZS1 and ZS2 Temperature control units T1 and T2 are connected. In the Temperature control units T1 and T2 become a medium M on one desired temperature heated or cooled and with With the help of the ZS1 and ZS2 supply systems to the heat exchanger supplied in the shaft W or in the housing G.
- the known system has the disadvantage that for the separate supply systems ZS1 and ZS2 also two Temperature control units T1 and T2 must be provided.
- the advantage the independent temperature setting for shaft W and Housing G are extremely expensive Temperature control units T1 and T2 opposite.
- FIG. 2 to 4 are various according to the invention Devices for adjusting and stabilizing the Temperature of the material to be conveyed M is shown. All point three versions a single temperature control unit TA to which the supply system ZS to the heat exchangers in the housing G or in the shaft W in different ways are connected. So is a system in Fig. 2 shown, in which the heat exchanger parallel to the Temperature control unit TA are connected, i.e. that the Medium M in the supply system ZS before corresponding heat exchanger the same temperature having.
- the embodiment according to FIG. 3 a parallel connection of the heat exchangers. Indeed is done here by merging the lines in front of the Heat exchangers a mix and therefore a Temperature compensation of the media M in front of the temperature control unit TA.
- Fig. 4 is an embodiment shown in 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 housing G out.
- the waste heat generated in the wave W by the medium M is transported into the housing G, i.e. Shaft W and housing G act like a temperature control unit.
