Lub teb compressors txoj kev xav ntawm dov piston hom yog tias lub piston rotating uas tseem hu ua rotor rotates nyob rau hauv kev sib cuag nrog lub contour ntawm lub tog raj kheej thiab ib tug taag hniav compresses lub tub yees.Piv nrog rau cov reciprocating compressors, cov teb compressors yog compact thiab yooj yim hauv kev tsim kho thiab muaj tsawg qhov chaw.Tsis tas li ntawd, lub teb compressors ua tau zoo nyob rau hauv coefficient ntawm kev ua tau zoo thiab efficiency.Txawm li cas los xij, qhov tseeb thiab kev tiv thaiv abrasion yuav tsum tau siv rau kev ua cov khoom sib tiv tauj.Rau lub sijhawm tam sim no, hom dov piston feem ntau yog siv.
