17、，消耗的能量就有差異。速度型的透平式空壓機(jī)的效率低，如把10m3自由空氣壓縮成0.6MPa的壓縮空氣，由排量為1000 m3/h的透平式空壓機(jī)生產(chǎn)，耗能1.77kW?h。而生產(chǎn)同樣數(shù)量和壓力的壓縮空氣，如用同樣排量的活塞式空壓機(jī)生產(chǎn)，僅耗能0.83kW?h。因此，從節(jié)能角度出發(fā)，空壓機(jī)的節(jié)能與空壓機(jī)的結(jié)構(gòu)型式有關(guān)。在選擇空壓機(jī)時(shí)，采用具有完善級(jí)間冷卻的多極壓縮機(jī)可節(jié)省能量、提高效率。例如二級(jí)壓縮比單級(jí)壓縮節(jié)能15%以上，三級(jí)壓縮比二級(jí)
