Definitions

  • a pneumo-hydraulic converter with reciprocating double pistons is known. the one with the best possible efficiency a compressed air reservoir with a hydraulic circuit connects, such that energy can flow into the store (charging) or from the store can be removed (unloading).
  • US-A 2,751,144 shows a compressor, i. H. a device with the hydraulic Work can be converted into pneumatic work. With this device, the Gas is compressed during the working stroke of the piston, the outside of the A cooling device is provided in the cylinder. This makes cooling possible protect the compressor from overheating overall, but it is not possible during the compression a significant amount of heat without adding or removing heat. Therefore the gas will heat up during the working stroke of the piston.
  • the compression work required however increases with the temperature of the gas, so that the efficiency of a such a compressor is low.
  • isothermal compression however, it makes it necessary to continuously dissipate heat during the working stroke. This is however, so far it has not been sufficient at technically usable working speeds Way possible.
  • the object of the invention is to achieve good efficiency while increasing the To achieve clock frequency.
  • This heat exchanger can either run with the reciprocating piston set or stay firm.
  • the heat exchanger running is about a third less Sliding seals require and also the tubular bundle the kink and dent resistance the piston set significantly increased
  • the description is based on the representation of the Restrict converters with a rotating heat exchanger: the desired increase in Clock frequency forces a radically dead space-reducing workspace arrangement.
  • the high buckling forces caused the buckling strength to become an extremely important one constructive factor that is also taken into account in the arrangement of the valves got to.
  • the high-pressure converter consists of three coaxial coaxial cables of approximately the same length Cylinder tube pieces, the pre-pressure tube 1, which surrounds the pre-pressure piston 2, has a substantially larger diameter than the two in relation to the pre-pressure tube 1 symmetrically arranged high-pressure chamber tubes 3a, 3b, which are also longitudinally symmetrical Include high pressure pistons 4a, 4b.
  • the pre-pressure pipe 1 analogously via valve flanges 5a, 5b with the two screwed-in high pressure chamber tubes 3a, 3b connected, each fastened by means of screw caps 6a, 6b Connection covers 7a, 7b are completed.
  • a set of three pistons that are mechanically firmly connected by the tubular rod 8 are and thus define 2 x 3 working spaces, namely between the connection covers 7a, 7b and the high-pressure pistons 4a, 4b, the oil spaces 9a, 9b, between the high-pressure pistons 4a, 4b and the valve flanges 5a, 5b, the high pressure air spaces 10a, 10b and between the Valve flanges 5a, 5b and the pre-pressure piston 2, the air pre-pressure spaces 11a, 11b.
  • the Air high-pressure spaces 10a, 10b are with the air pre-pressure spaces 11a, 11b via the exchange valves 12a, 12b connected, the outside world communicates with the pre-pressure rooms 11a, 11b via the low pressure valves 13a, 13b and the air reservoir 14 can the air high pressure spaces 10a, 10b act on the high pressure valves 15a, 15b from the air reservoir 14 are supplied by the supply lines 16a, 16b via the connections 17a, 17b.
  • pilot control by means of hydraulic loading is shown in 1 on the high pressure valves 15a, 15b, the pressure chambers 18a, 18b each of the electrical 2-way pilot valves connected to a pressure source 19 20a, 20b are either released or acted upon, whereby the valve pistons 21a, 21b are moved over the rods 22a, 22b with nuts 23a, 23b with the high pressure valves 15a, 15b are connected.
  • Similar devices can also be used for the replacement valves 12a, 12b and the low pressure valves 13a, 13b are provided, here only the actuating rods 24a, 24b and 25a, 25b are shown.
  • a wiring option is available, starting at the oil connections 26a, 26b of the converter, with feed lines 27a, 27b to a 4-way valve 28, which is a variable hydrostatic unit 29 with a flywheel 30 and an electric motor / generator 31 acted upon.
  • the exchange circuit begins with the feed pump 32, which is the exchange liquid by the external exchanger 33 via the connection 34b in the connection cover 7b and through the feed pipe 35b into the tube rod 8.
  • the pre-pressure piston 2 relaxed air in room 11b is displaced into the environment via the open low-pressure valve 13b and at the same time that from the previous movement in the air high-pressure space 10a below Prepressed air remaining through the open exchange valve 12a through the expanding Form pressure chamber 11a brought to outlet pressure.
  • the hydrostatic unit emerging oil sucked into the oil space 9a.
  • the through the upholstery in the Oil space 9b is therefore not only the result of high pressure in the air high-pressure chamber 10b, this also adds to that by the form on the large area of the pre-pressure piston 2 resulting thrust, which over the tubular rod 8 and Tubes 38 of the exchanger bundle is transmitted. There is a risk of kinking here!
  • the converter only works as a compressor, there is no forced control of the valves, it only has to switch the 4-way switching valve 28 either automatically (through the pressure peak at the stop) or be synchronized with the converter stroke using a proximity switch.
  • the compressor can also be used for simple compression tasks (e.g. for cooling circuits) without pre-pressure cylinder.
  • the tube bundle heat exchanger can do this either fixed or moving, as there are no buckling forces.
