Benefits of technology
[0008] In view of the disadvantages above, it is an object of the invention to provide a method of preventing density of an inert gas in a high-pressure storage tank from lowering without losing the inert gas and a system therefor.
Problems solved by technology
However, in this case, a compressed gas in the compression chamber leaks into the crank case on the outer circumferential surface of the piston and is uselessly lost.

Embodiment Construction
[0012] In an inert gas source 1 such as an inert gas generator of N2 gas or an inert gas cylinder which is filled with N2 under pressure, 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.
[0013] 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. Between the outlet 11 and the check valve 13, a relief valve such as a two-way electromagnetic valve 16 is connected to the conduit 12.
[0014] A pressure switch 23 of the high-pressure storage tank 14 is connected to a controller 22 via a connecting line 24.
[0015] A discharge valve 26 is connected to a discharge hole 25 of the high-pressure storage tank 14. To fill the high-pressure storage tank 14 with an inert gas, the supply valve 5 is opened with instructions...

An inert gas is fed from an inert gas source to a piston-reciprocating compressor and compressed therein. The compressed gas is sent to a high-pressure storage tank. Pressure of the gas in the high-pressure storage tank is detected. When it reaches an upper limit, the piston-reciprocating compressor is stopped by a controller. At the same time, the gas is not fed from the inert gas source into the piston-reciprocating compressor and the gas from the compressor is released to outside. Meanwhile, when the pressure of the gas in the high-pressure storage tank reaches to a lower limit, the compressor starts. At the same time, the inert gas source is allowed to communicate with the compressor, and the gas which reaches to a desired density after the gas is released is sent from the compressor to the tank.
Description
BACKGROUND OF THE INVENTION [0001] 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. [0002] An inert gas such as N2 gas in a cylinder or produced in a N2 gas generator is compressed by a booster compressor and forwarded to a high-pressure storage tank or part for use. [0003] An ordinary piston-reciprocating compressor is generally employed as a booster compressor. [0004] An inert gas is compressed by a piston-reciprocating compressor. When 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. [0005] The inert gas is diluted by air, so that the density of the inert gas in the compression chamber is reduced. [0006] To pr...
