Definitions

  • the present invention relates to a method of compressing an inert gas sent from an inert gas source by a piston-reciprocating compressor and a system therefor.
  • An inert gas such as N 2 gas in a cylinder or produced in a N 2 gas generator is compressed by a booster compressor and forwarded to a high-pressure storage tank or part for use.
  • An ordinary piston-reciprocating compressor is generally employed as a booster compressor.
  • An inert gas is compressed by a piston-reciprocating compressor.
  • a supply valve between the inert gas source and the compressor is closed, pressure of a gas in a compression chamber on a piston becomes less than atmospheric pressure, so that air in a crank case under the piston likely invades into the compression chamber through the outer circumferential surface of the piston.
  • the inert gas is diluted by air, so that the density of the inert gas in the compression chamber is reduced.
  • the supply valve is left open to let the inert gas source to communicate with the compression chamber even when the compressor stops, so that the compression chamber of the compressor does not become negative pressure.
  • FIG. 1 is a diagram showing one embodiment of the present invention.
  • FIG. 2 is a diagram showing another embodiment of the present invention.
  • a sucking conduit 3 from an outlet hole 2 is connected to an inlet 10 of a piston-reciprocating compressor 9 having a piston 8 which reciprocates in a cylinder by a motor, via a supply valve 5 such as a two-way electromagnetic valve.
  • a release conduit 12 from an outlet 11 of the piston-reciprocating compressor 9 is connected to a high-pressure storage tank 14 via a check valve 13 .
  • a relief valve such as a two-way electromagnetic valve 16 is connected to the conduit 12 .
  • a pressure switch 23 of the high-pressure storage tank 14 is connected to a controller 22 via a connecting line 24 .
  • a discharge valve 26 is connected to a discharge hole 25 of the high-pressure storage tank 14 .
  • the supply valve 5 is opened with instructions from the controller 22 , the relief valve 16 is closed after opening during a certain time, and the piston 8 is reciprocated in the piston-reciprocating compressor 9 by the motor 6 .
  • the inert gas from the inert gas source 1 via the sucking conduit 3 is compressed by the piston-reciprocating compressor 9 and forwarded to the high-pressure storage tank 14 via the check valve 13 .
  • the pressure switch 23 detects it.
  • the controller 22 instructs the supply valve 5 to close and to stop the motor 6 to allow the piston-reciprocating compressor 9 to stop.
  • the low-density inert gas in the release conduit 12 is released for certain time.
  • released inert gas from the piston-reciprocating compressor 9 becomes more than a certain density to make the controller 22 instruct to allow the relief valve 16 to close.
  • the piston-reciprocating compressor 9 does not suck external air, but allows high-density inert gas from the inert gas source 1 to go to the high-pressure storage tank 14 via the check valve 13 .
  • FIG. 2 shows another embodiment of the present invention, in which a three-way electromagnetic valve 28 is provided instead of the two-way electromagnetic valve 16 and the check valve 13 in FIG. 1 .
  • a supply valve 5 in a sucking conduit 3 is opened and the three-way electromagnetic valve 28 of a release conduit 12 is opened for a certain time, and then closed.
  • the supply valve 5 is opened and the three-way electromagnetic valve 28 is opened, so that low-density inert gas in the sucking conduit 3 and the compression chamber is released from the release conduit.
  • release is stopped by switching the three-way electromagnetic valve 28 to allow it to communicate with the storage tank 14 .
