Abstract

For å tilveiebringe et kompressoranlegg (100) om- fattende en kompressor (13), som med sin utgang er til- sluttet et luftreservoar (10) og drives av en drivinn- retning (12), som på en første driftsmåte kan drives med et nominelt omdreiningstall (Nnom), samt en første trykkovervåker (DW1), som overvåker trykket i luft- reservoaret (10) og kopler inn drivinnretningen (12) via en styring (11), når trykket i luftreservoaret (10) ligger under et første minimumstrykk (pminl), og kopler ut drivinnretningen (12) igjen, når et maksimaltrykk (pmax) overskrides i luftreservoaret (10), der kompressorens slitasje kan minskes merkbart uten ulempe for anleggets konstante drift foreslås at drivinn- retningen (12) ved siden av den første driftsmåten med nominelt omdreiningstall (Nnom) kan drives på en andre driftsmåte med minst et ytterligere, i forhold til det nominelle omdreiningstallet (Nnom) redusert om- dreiningstall (Nred), at den første trykkovervåkeren (DW1) kun innkoples, når det første minimumstrykket (pmlnl) underskrides ved fallende trykk, og at den første trykkovervåkeren (DW1) styrer drivinnretningen (12) på den andre driftsmåten med redusert omdreinings- tall (Nred).In order to provide a compressor system (100) comprising a compressor (13), which with its output is connected to an air reservoir (10) and is driven by a drive device (12), which in a first operating mode can be operated with a nominal rpm (Nnom), as well as a first pressure monitor (DW1), which monitors the pressure in the air reservoir (10) and switches on the drive (12) via a control (11) when the pressure in the air reservoir (10) is below a first minimum pressure (pminl), and switch off the drive (12) again when a maximum pressure (pmax) is exceeded in the air reservoir (10), where the wear of the compressor can be noticeably reduced without the inconvenience of the constant operation of the system that the drive device (12) is adjacent to it. first mode of operation with nominal speed (Nnom) can be operated in a second mode of operation with at least one further, in relation to the nominal speed (Nnom) reduced speed (Nred), that the first pressure monitor (DW1) is only switched on, now when the first minimum pressure (pmlnl) is lowered by falling pressure, and the first pressure monitor (DW1) controls the drive device (12) in the second mode of operation with reduced rotational speed (Nred).
