Definitions

  • the invention relates to an expansion vessel according to the preamble of Claim 1 and a hydraulic system with an expansion tank.
  • the invention can be used for example in hydraulic systems for rail vehicles be both liquid cooling of power converters, traction motors and transformers as well as heating passenger compartments.
  • in converters, traction motors and transformers (hereinafter also referred to as heat generators) Absorb heat loss via a suitable coolant, one Recirculating cooler (hereinafter also referred to as the first heat consumer) and dissipate it to the outside atmosphere.
  • An expansion tank is used with a ventilation device for receiving the during the heating of the Cooling liquid necessarily increases in volume of the coolant and for ventilation.
  • additional Facilities required to deliver the desired coolant flows to the recooler and to the heating device (hereinafter also referred to as a second heat consumer referred to) d.
  • additional facilities are necessary with their help in heating operation at least part of the heated coolant decoupled from the cooling circuit and diverted via the heating device becomes.
  • ventilation is also problematic of these additional facilities. In many cases, it is common that the additional Equipment collecting air via manually operated ventilation valves let down.
  • the invention has for its object an expansion vessel of the beginning Specify the type mentioned, in addition to its volume compensation functions and venting for guiding and dividing coolant flows from at least one heat generator to at least two heat consumers suitable is. Furthermore, a hydraulic system with such an expansion tank is said to be be specified, which has a clear system piping and can be easily vented.
  • This task is related to the expansion tank in connection with the Features of the preamble according to the invention by the in the characterizing part of the claim 1 specified features solved.
  • the invention is described below with reference to the embodiment shown in the drawing explained.
  • the rail vehicle has power converters to be cooled, Travel motors and transformers that are combined in one to be cooled Traction system 1 are shown.
  • the traction system corresponds to 1 a heat generator.
  • the cooling is preferably carried out with process water added antifreeze.
  • the heated coolant is pumped by means of a circulation pump 3 via a return line 2 conveyed from the traction system 1 to an expansion vessel 4 and arrives via a first inlet 5 into a primary container 11 of this expansion vessel.
  • the heated coolant leaves the primary container 11 a first output 6 and reaches the input of a recooler 7.
  • the air-cooled Recooler 7 will cool the liquid to an instantaneous outside air temperature dependent temperature level cooled.
  • the cooled coolant leaves the outlet of the recooler 7 and passes through a three-way valve 8 and a flow line 9 to the traction system 1.
  • a three-way valve 8 and a flow line 9 to the traction system 1.
  • the recooler 7 a first heat consumer.
  • the further connection of the three-way valve 8 is connected to a bypass line 10, which is connected to the line between output 6 and recooler 7.
  • a bypass line 10 which is connected to the line between output 6 and recooler 7.
  • the coolant in turn leaves the primary container 11 via the outlet 6, where the further coolant flows explained above follow.
  • a separate (not shown) pump takes over the coolant transport between primary tank 11 and heating device 21.
  • the heating device 21 corresponds to a second heat consumer.
  • the coolant flowing in via input 5 can become also divide into two partial flows to the outputs 6, 20. This is due to the current Determines the heat requirement of the heating device 21, which for example the desired passenger compartment heating of the rail vehicle via thermostats makes.
  • An expansion line 18 leads from the return line 2, i. H. from the suction side the circulation pump 3, into a secondary container 13 of the expansion vessel 4, which is primarily used to accommodate the expansion of the heated coolant resulting additional volume serves. Above the coolant level An air collecting space 14 forms in the secondary container 13. This Air collection space 14 is within a certain via an automatic vent valve 15 Predefinable pressure limits - both overpressure and underpressure are in Desired way specified - connected to the outside atmosphere, so that a complete ventilation in a relatively short time and with very little personnel is possible.
  • a connection 16 is used for quick ventilation between primary container 11 and secondary container 13 essential. This connection 16 opens at the highest point of the primary container 11 and the hydraulic one Systems and is slightly permeable to air, but difficult for the coolant permeable.
  • a pipeline serves as a connection 16 between the two Containers 11, 13, which on the one hand in the upper region of the primary container 11 and on the other hand, opens into the lower region of the secondary container 13.
  • the pipeline is of relatively small diameter to the circulating coolant flow to keep the ventilation circuit as small as possible.
  • the secondary tank can be used to minimize the circulating coolant flow 13 be constructed from two partial containers, which have a partially permeable Partition wall are interconnected. It opens into the first part of the container the connection 16 (pipeline) and to the second sub-tank is the expansion line 18 connected.
  • the expansion vessel according to the invention is not based on this limited, but can also have connections for other heat generators and heat consumers if this is necessary for specific designs.
