Definitions
- the invention relates to a compressor according to the preamble of claim 1.
- the piston of a compressor should be stored by a gas bearing.
- part of the gas compressed by the compressor is branched off from the useful gas stream and passed through nozzles into the gas bearing.
- the problem with this arrangement is the loss of useful gas in particular because the gas loss depends on the thermodynamic operating point of the compressor. That at high end pressure of the gas more gas is lost than at low final pressure. As a result, the gas loss and the
- Load capacity of the gas bearing depends on the compressor working point.
- the object is achieved by the features of claim. Further developments are specified in the subclaims.
- the invention relates to a compressor with self-supplying gas storage, in which the supply pressure is independent of the delivery pressure. This optimizes the gas storage according to structure and function.
- FIG. 2 shows a compressor according to FIG. 1 with optimized gas bearing
- FIG. 3 shows a first connection from the gas reservoir and compression space
- FIG. 4 shows a second connection of gas reservoir and compression space.
- FIG. 1 shows a linear compressor in which a linearly guided compressor piston 2 acts on a gas volume 1.
- a gas bearing is formed between the piston 2 and the inner wall of the hollow cylinder 10.
- the gas space 1 is a low-pressure chamber 15 and a high-pressure chamber 20 assigned.
- the low-pressure space 15 has a gas inlet 16 and an inlet valve 17.
- the high-pressure space 20 has a gas outlet 21 and an outlet valve 22.
- Figure 2 shows an improved design of the gas bearing.
- the bearing nozzles 11 are fed from a separate gas reservoir 25, in which there is a sufficient amount of gas matching pressure.
- the gas flow through the camp and thus the Nozzle number, nozzle diameter and gas pressure can be chosen so that the bearing carries reliable.
- a second gas outlet 33 with channel 30 is mounted in the compression chamber 1.
- the pressure in the gas reservoir 25 is determined by the position A of the gas outlet 33 in the compression chamber and the pressure drop in the connecting line and is below the compression end pressure.
- the channel 30 is designed such that the pressure drop becomes minimal.
- the gas bearing can be fed directly from the high pressure, wherein the gas flow is limited by a pressure reducer to the minimum necessary bearing pressure.
- connection between the compression chamber 1 and the gas storage reservoir 25 is established via a valve 30 closable channel 30 according to FIG. 3 or a channel 40 without a valve, but with anisotropic flow resistance 41 according to FIG. In both cases it is ensured that gas from the compression chamber 1 enters the gas reservoir 25. Conversely, however, no gas or only slightly gas can pass from the reservoir 25 back into the compression space 1 through the valve 31 or through the anisotropic flow resistance 41.
- the volume of the gas reservoir 25 is selected to be reliably fed from the reservoir 25 during repetitive operation, particularly when the gas bearing is reliably fed during the portion of the compression cycle in which the reservoir is not being fed from the high pressure space 20.
- the gas reservoir 25 can be provided with an outlet valve 26.
- the pressure in the reservoir 25 can be maintained permanently or at least longer, whereby the time period in which the compressor can remain switched off without the gas bearing loses the load capacity, can be extended.
- the outlet valve 26 of the gas reservoir is opened again to first restore the carrying capacity of the gas bearing and only then to begin the movement of the piston 2.
- start-up is, with the gas reservoir 25 empty, first to move the piston 2 with a reduced stroke in order to pressurize the gas reservoir 25. As soon as this is the bearing capacity of the gas bearing, the stroke can be increased to normal and normal compressor operation begins.
- Another alternative would be an outlet valve of the compression chamber, which opens independently of the pressure behind the outlet valve only above a certain pressure. It can thereby be achieved that during start-up of the compressor first the gas reservoir 25 is filled and only then uses the Nutzgasstrom.
