Definitions

the invention relates to a device and a method for controlling a double-acting single or multi-stage piston compressor.
a reciprocating compressor machine which is formed in one or two stages and is driven by a linear motor as a linear drive.
the pressures and temperatures are recorded via sensors.
the recorded measured data and the compressor control are used to control the compressor.
the invention has for its object to provide a device that the compression of a reciprocating compressor is improved without much technical effort, and a method indicate that the control of such a reciprocating compressor is better designed.
the device of a double-acting single-stage or multistage piston compressor has the advantage that the suction side of the cover-side cylinder side is connected to the crank-side cylinder side and thus the crank-side cylinder is depressurized.
a connecting line of a fluidic device establishes the connection of the suction side of the top-side cylinder side with the crank-side cylinder side.
At least a first valve is arranged in the connecting line of the fluidic device.
At least one second valve is arranged in the suction line of the suction side of the cylinder side on the cover side.
the second valve is arranged in the suction line of the suction side before the confluence of the connecting line of the fluidic device in the suction line in the direction of the suction side of the cover side cylinder side.
the gas in the cylinder on the cover-side cylinder side is compressed when moving the piston by the piston rod in the cylinder in the direction of the cover-side cylinder side and when exceeding a predetermined intermediate or final pressure is pushed out of the pressure line of the cover-side pressure side and at the same time via the suction line of the cover-side suction side, a gas is sucked into the crank side cylinder.
Another advantage of the method is that the gas from the crank-side cylinder side via the connecting line of the fluidic device to the cover-side cylinder side when moving the piston after passing through the top dead center in the direction of the crank-side cylinder side out and the crank-side cylinder side is pressure-relieved.
a still further advantage of the method is shown in the fact that the gas is compressed on the crank side cylinder when returning the piston to the bottom dead center by blocking the first valve in the connecting line of the fluidic device and at the same time the top side cylinder 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 the second valve in the suction line is closed.
the pre-compressed gas which exceeds the pressure in the suction line, pushed into the lid side cylinder.
Fig. I 1 shows a cylinder 01 in which a piston 02 arranged on a piston rod 03 is guided parallel to the axis between a cylinder side 04 on the cover side and a cylinder side 05 on the crank side.
the cover-side cylinder 04 is connected via a connecting line 06 of a fluidic device with the crank-side cylinder 05. Furthermore, the connecting line 06 of the fluidic device is connected to a suction line 07 a suction side, which is arranged on the cover-side cylinder side 04.
the cover-side cylinder 04 is further provided with a pressure line 08 a pressure side, which is attached to the cover-side cylinder side.
Fig. II shows the same elements as Fig. I and will therefore not be described further.
a first valve 09 is arranged in the connecting line 06 of the fluidic device.
a second valve 10 is mounted in the suction line 07 of the suction side of the cover side cylinder side 04 in front of the junction of the connecting line 06 of the fluidic device in the suction line, and seen in the direction of the suction side of the cover side cylinder side 04.
the device of a single-stage or multistage piston compressor thus comprises at least one cylinder 01 with a piston 02 and a piston rod 03 and a cover-side cylinder 04 and a crank-side cylinder 05.
the gas is in the cylinder 01 compressed on the cover side cylinder side 04 and ejected when exceeding a predetermined intermediate or final pressure from the pressure line 08 of the pressure side of the cover side cylinder side 04.
gas is sucked into the crank-side cylinder side 05 via the suction line 07 of the suction side of the cover-side cylinder side 04.
the stage pressure ratio on the cover-side cylinder side 04 can be reduced, whereby the compression temperature is reduced.
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 crank side cylinder 05 during 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 of the suction side of the cover side cylinder side 04.
the cover-side cylinder 04 is filled with gas from the suction line 07.
the gas pre-compressed on the crank-side cylinder 05 is pushed into the cover-side cylinder side 04 and the pressure on the suction side of the cover-side cylinder side 04 is raised relative to 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.
