Definitions
- the invention relates to a method for compressing a gaseous medium, in particular hydrogen, wherein the compression by means of a reciprocating compressor whose piston (s) has a dynamic seal (s), takes place.
- the invention relates to a reciprocating compressor with one or more cylinder chambers, wherein the piston or pistons have dynamic seals.
- Dynamic seals In generic methods for compressing a gaseous medium and in generic reciprocating compressors, as used for example in the compression of natural gas or hydrogen, resulting in wear after about 500,000 cycles on the dynamic seals. These unavoidable signs of wear result in a reduction in performance and can possibly lead to failure of the reciprocating compressor. Dynamic seals must therefore be regularly replaced with a relatively large amount of effort.
- the term "dynamic seal” are to be understood in the usual way seals, which are subject to a sliding movement and must be tight.
- the life cycle and thus the exchange cycle of its dynamic seal is hitherto determined via the measured cycle number of a piston and, when a predetermined number of cycles or before the predetermined cycle number has been reached, the compression capacity drops, the dynamic seal is replaced.
- replacement not only means maintenance and investment costs, but also unwanted downtime.
- Object of the present invention is to provide a generic method for compressing a gaseous medium and a generic reciprocating compressor, in which the maintenance intervals extended and thus the cost of its operation, in particular the maintenance costs, can be reduced.
- the method according to the invention is characterized in that a graphite-containing medium is supplied to the cylinder space (s) before and / or during the compression, wherein the graphite-containing medium is designed such that it bears against the dynamic seal (s).
- the piston compressor according to the invention is characterized in that means for supplying a graphite-containing medium in the cylinder or the cylinder spaces are provided.
- the graphite-containing medium used is graphite dust, molybdenum and / or other dusts or dust mixtures which have lubricating properties.
- graphite, talc, cotton flakes, nut shell granules, sawdust, etc. are used as dusts or dust mixtures which have lubricating properties.
- the graphite-containing medium at least one sealing additive, such as cotton flakes, mustard fiber and / or other tipping and / or lumpy additives such as sawdust, plastic granules, Nutschalengranulat added are or are added.
- sealing additive such as cotton flakes, mustard fiber and / or other tipping and / or lumpy additives such as sawdust, plastic granules, Nutschalengranulat added are or are added.
- the aforementioned addition of sealing additives such as cotton flakes, etc. to the graphite-containing medium enhances the above-described sealing effect.
- the supply of the graphite-containing medium which may be admixed with at least one sealing additive, takes place in the cylinder chamber (s) by means of compressed air, internal gas - ie the gas to be compressed (mixture) - and / or mechanical devices, such as piston-type dispensers, Metering locks, blast wheels, etc.
- the supply of the graphite-containing medium for example via the valve opening (s) and / or the inlet opening (s), via which the gaseous medium enters the cylinder space, take place.
- the supply of the graphite-containing medium in the cylinder or the chambers can be made continuously or discontinuously.
- the piston compressor - according to an advantageous embodiment of the piston compressor according to the invention - for example, a
- Compressed air supply device over which - preferably controllable - the required or desired mass flow of graphite-containing medium is supplied. DenkbaMst but also to introduce a predetermined amount of graphite-containing medium in the cylinder chamber (precaution) when reaching a predetermined number of cycles.
- the invention makes it possible to extend the service life of dynamic seals, thus extending their maintenance intervals, resulting in a cost, especially a maintenance cost reduction results.
- the medium used is also relatively inexpensive and the required Zunnenzedur requires no disproportionate design effort.
