Definitions

the invention relates to a method for controlling a double-acting single or multi-stage piston compressor and such a piston compressor.
a two-stage pump with a housing having an inlet and an outlet.
a pumping device is arranged in the housing.
a first chamber is in communication with the inlet when the chamber receives a fluid upon movement of the pumping device in a first position.
a second chamber communicates directly with the outlet.
a first line is arranged, via which fluid can flow on movement of the pumping device into a second position from the first chamber into the second chamber.
a second line is provided, via which fluid can flow from the first chamber directly to the outlet.
the invention has for its object to provide a method that the compression of a reciprocating compressor is improved without much technical effort, and to provide a reciprocating compressor, which is better designed for a control of such a method.
the method for controlling a double-acting single-stage or multi-stage piston compressor has the advantage that the gas in the second chamber on the side of the cylinder bottom when returning the piston to the bottom dead center Blocking a first valve in a arranged between the first chamber and the second chamber connecting line of a fluidic device compressed and at the same time the first chamber on the side of the cylinder cover is filled with gas from the suction line.
the first valve in the connecting line of the fluidic device is opened and at the same time a second valve in the suction line is closed.
the precompressed gas which exceeds the pressure in the suction line, is pushed out of the second chamber via the connecting line and the connected suction line into the first chamber on the side of the cylinder cover.
Another advantage of the method is the fact that the supply of compressed gas is adjusted to the required volume by regulating the crank-side pre-compression and that the compression heat is reduced by reducing the step pressure ratio.
a still further advantage of the method is that the gas from the second chamber on the side of the cylinder bottom through the connecting line of the fluidic device to the first chamber on the side of the cylinder cover when moving the piston after passing through the top dead center in the direction of the cylinder bottom and the second chamber on the side of the cylinder bottom is depressurized.
the gas is compressed in the first chamber of the cylinder during movement of the piston by the piston rod in the cylinder in the direction of the cylinder cover.
the compressed gas is then pushed out when a predetermined intermediate or final pressure in the arranged in the cylinder cover pressure line.
a gas is sucked into the second chamber via the suction line attached to the cylinder cover.
the generated pressure which is higher than the suction pressure in the suction line, is regulated by means of a predetermined pressure measurement via the connecting line.
a double-acting single-stage or multi-stage piston compressor for carrying out a method according to the invention has the advantage that the first chamber is connected on the side of the cylinder cover via a connecting line of a fluidic device to the second chamber on the side of the cylinder bottom and that at least one in the connecting line first valve is arranged.
a second valve is mounted in the suction line on the side of the cylinder cover.
the Fig. I shows a cylinder 01 in which a arranged on a piston rod 03 piston 02 is guided axially parallel between a cylinder cover 04 and a cylinder base 05.
a connecting line 06 of a fluidic device is connected to a second chamber 12 formed between the cylindrical base 05 and the crank-side surface of the piston 02.
the connecting line 06 of the fluidic device is connected to a suction line 07, which is arranged on the cylinder cover 04.
a pressure line 08 is still connected.
Fig. II partly shows the same elements as Fig. I , which will therefore not be described further.
a first valve 09 is additionally arranged in the connecting line 06 of the fluidic device.
a second valve 10 is mounted in the suction line 07 in front of the junction of the connecting line 06 of the fluidic device in the suction line, in the direction of the cylinder cover 04 seen.
the double-acting single or multi-stage piston compressor thus comprises at least one cylinder 01 with a piston 02 and a piston rod 03 and a cylinder cover 04 and a cylinder bottom 05, wherein between the cylinder cover 04 and the surface of the piston 02, a first chamber 11 and between the cylinder bottom 05 and the crank-side surface of the piston 02, a second chamber 12 is formed.
the stage pressure ratio on the side of the cylinder cover 04 can be reduced, which reduces the compression temperature.
the reduction of the compression temperature affects straight with monatomic gases, such as. As helium and argon, with a high isentropic component in the compression of the heat development advantageous.
the gas is compressed on the side of the cylinder bottom 05 upon retraction of the piston 02 in the bottom dead center, since the gas can not flow through the locked first valve 09 in the connecting line 06 of the fluidic device in the suction line 07 on the side of the cylinder cover 04 ,
the first chamber 11 is filled on the side of the cylinder cover 04 with gas from the suction line 07.
the first valve 09 is opened in the connecting line 06 of the fluidic device and at the same time the second valve 10 is closed in the suction line 07.
the gas pre-compressed in the second chamber 12 on the side of the cylinder bottom 05 becomes gas in the first chamber 11 on the side of the cylinder cover 04 pushed and lifted the pressure on the suction side of the cylinder deck 04 against an unregulated suction pressure.
the supply quantity of the compressed gas is adjusted by the control of the crank-side pre-compression and at the same time reduces the heat of compression by reducing the step pressure ratio.
