Description
Verfahren zum Betreiben von Druckluftanlagen in Bergwerken u. dgl. Gemäß dein Patent 388708 werden in Bergwerken u. dgl. mit ausgedehntem Arbeitsbereich in das von einem über Tage aufgestellten Großkompressor gespeiste Druckluftnetz an den Verbrauchsstellen, oder nicht allzu fern von ihnen, ein- oder inehrstuf ge Hilfskompressoren eingeschaltet, die entweder die Preßluft .aus dem l@Tetz entnehmen und auf höhere Pressung bringen oder frische Luft ansaugen und in das Preßluftnetz drücken.Method for operating compressed air systems in mines and the like. According to your patent 388708, in mines and the like with an extensive working area into the compressed air network fed by a large compressor installed above ground at the consumption points, or not too far from them, single or multi-level Auxiliary compressors switched on, which either take the compressed air from the l @ Tetz and bring it to a higher pressure or suck in fresh air and into the compressed air network to press.
Nach der Erfindung geschieht die Drucksteigerung durch diese Hilfskompressoren nicht an oder unmittelbar vor den Arbeitssteller, sondern vor Druckluftbehältern, die in an sich bekannter Weise in das Pr:eßluftnetz eingeschaltet sind und die in Zeiten geringsten Verbrauches vom Preßluftrohrn.etz mit Preßluft gefüllt werden .und aus denen bei gesteigertem Verbrauch die für den Betrieb der Arbeiitsgerätschaften benötigte Druckluft entnommen wird. 'Hierdurch ist es .möglich, die in den Druckluftbehältern enthaltene Preßluft auf nahezu gleicher Spannungshöhe zu erhalten und den Spannungsabfall auf die von den Drucklufftbehältern zu den Verbrauchsstellen führenden Speiseleitungen zu beschränken, während bai dem bisher üblichen Verfahren durch die Entnahme der Druckluft aus den Behältern die Spannung in diesen, entsprechend dem Druckabfall im gesamten Preßluftrohrnetz, (lauernd sinkt.According to the invention, the pressure increase is done by these auxiliary compressors not on or directly in front of the work station, but in front of compressed air tanks, which are switched on in a manner known per se in the test air network and which are in Times of the lowest consumption are filled with compressed air from the compressed air pipe network . And from those for the operation of the work equipment in the case of increased consumption required compressed air is taken. 'This makes it possible to use the compressed air tanks contained compressed air at almost the same voltage level and the voltage drop on the feed lines leading from the compressed air tanks to the consumption points to restrict, while bai the previously usual procedure by removing the Compressed air from the tanks increases the voltage in them, according to the pressure drop in the entire compressed air pipe network, (lurking sinks.
Bei der meist nur geringen erforderlichen Drucksteigerung genügen einstufige Kolbenkompressoren oder bei Verwendung von Kreiselverdichtern solche mit einer geringen Anzahl von Laufrädern für den gedachten Zweck. Die sie betreibenden Kraftmaschinen können auch hier von der Preßluft so beeinflußt werden, daß sie sich selbsttätig an- und abschalten.Sufficient for the usually only slight increase in pressure required single-stage piston compressors or, if centrifugal compressors are used, such with a small number of wheels for the intended purpose. Those who run them Here too, power machines can be influenced by the compressed air in such a way that they move switch on and off automatically.
