Definitions

  • borate is an inexpensive crystal and since it is generally used with a percentage of less than 10% and although the water needs to be deionized (otherwise the borate would precipitate the calcium carbonate), the liquid remains less expensive than the required oil refill in oil compressors.
  • solid inhibitors such as sodium chromate, represent a health hazard, or are not stable over time, in the presence of oxygen.

Claims (8)

1. Anlage zur Luftkompression, mit einem Rotationskompressor (1), der an seiner Druckseite mit einem teilweise mit Wasser gefüllten Behälter (5) verbunden ist, dessen unterer Teil über eine Leitung (7) mit wenigstens einer am Rotationskompressor befindlichen Einspritzöffnung (11) verbunden ist, wobei diese Leitung mit einem Mittel (10) zum Abkühlen des Wassers versehen ist, dadurch gekennzeichnet, daß das Wasser gelöstes Borat in einer für die Verhinderung der Korrosion der eisenhaltigen Metalle ausreichenden Konzentration enthält.
2. Anlage zur Luftkompression gemäß Anspruch 1, dadurch gekennzeichnet, daß das Borat Kaliumborat ist.
3. Anlage zur Luftkompression gemäß Anspruch 1, dadurch gekennzeichnet, daß das Borat Tetraborat-Dikalium-Tetrahydrat ist.
4. Anlage zur Luftkompression gemäß Anspruch 1, dadurch gekennzeichnet, daß sich in der Ansaugleitung (2) des Kompressors Verschlußmittel (3) befinden, um die Ansaugleitung zu sperren, wenn sich der Kompressor in Ruhe befindet.
5. Verfahren zum Komprimieren von Luft in einem Rotationskompressor, mit den Schritten
- des Einspritzens einer Flüssigkeit in den Kompressor (1);
- des Trennens dieser Flüssigkeit von der vom Kompressor (1) gelieferten komprimierten Luft;
- des Verwendens dieser getrennten Flüssigkeit zum weiteren Einspritzen der Flüssigkeit in den Kompressor, dadurch gekennzeichnet, daß als Flüssigkeit Wasser verwendet wird, dem gelöstes Borat zugesetzt ist.
6. Verfahren gemäß Anspruch 5, dadurch gekennzeichnet, daß als Borat Kaliumborat verwendet wird.
7. Verfahren gemäß Anspruch 5, dadurch gekennzeichnet, daß als Borat Tetraborat-Dikalium-Tetrahydrat verwendet wird.
8. Verfahren gemäß einem der Ansprüche 5 bis 7, dadurch gekennzeichnet, daß die Ansaugleitung (2) des Kompressors (1) gesperrt wird, wenn sich der Kompressor in Ruhe befindet.
