Pamene pisitoni yobwereranso mu silinda ikupita kumanja, kupanikizika kuchipinda chakumanzere kwa pistoni mu silinda kumakhala kotsika kuposa mphamvu ya mumlengalenga PA, valavu yoyamwa imatsegulidwa, ndipo mpweya wakunja umalowetsedwa mu silinda.Njira imeneyi imatchedwa compression process.Pamene kupanikizika mu silinda ndipamwamba kuposa kuthamanga P mu chitoliro cha mpweya, valve yotulutsa mpweya imatsegulidwa.Mpweya woponderezedwa umatumizidwa ku chitoliro chotumizira mpweya.Njira imeneyi imatchedwa exhaust process.Kuyenda kobwerezabwereza kwa pisitoni kumapangidwa ndi makina otsetsereka oyendetsedwa ndi mota.Kuyenda kozungulira kwa crank kumasinthidwa kukhala kutsetsereka - kuyenda kobwerezabwereza kwa pistoni.

Compressor yokhala ndi izi nthawi zonse imakhala ndi voliyumu yotsalira kumapeto kwa njira yotulutsa mpweya.Pa kuyamwa kotsatira, mpweya woponderezedwa mu voliyumu yotsalayo udzakula, kuti muchepetse mpweya wotsekemera, kuchepetsa mphamvu ndikuwonjezera ntchito yopondereza.Chifukwa cha kukhalapo kwa voliyumu yotsalira, kutentha kumawonjezeka kwambiri pamene chiŵerengero cha psinjika chikuwonjezeka.Choncho, pamene kuthamanga kwa linanena bungwe ndi mkulu, siteji psinjika ayenera anatengera.Kuponderezana kwapang'onopang'ono kumatha kuchepetsa kutentha kwa mpweya, kupulumutsa ntchito yopondereza, kupititsa patsogolo mphamvu ya volumetric ndikuwonjezera kuchuluka kwa mpweya woponderezedwa.

Chithunzi 1 chikuwonetsa pisitoni ya mpweya wa pisitoni imodzi, yomwe imagwiritsidwa ntchito kwambiri pa 0 3 - 0.7 MPa pressure range system.Ngati kukakamizidwa kwa single-siteji pisitoni mpweya kompresa upambana 0 6Mpa, zolozera ntchito zosiyanasiyana adzatsika kwambiri, kotero psinjika multistage nthawi zambiri ntchito kusintha linanena bungwe kuthamanga.Pofuna kukonza bwino komanso kuchepetsa kutentha kwa mpweya, kuziziritsa kwapakati kumafunika.Kwa zida za piston air compressor zokhala ndi magawo awiri, kuthamanga kwa mpweya kumawonjezeka kuchokera ku P1 kupita ku P2 mutadutsa pa silinda yotsika, ndipo kutentha kumawonjezeka kuchokera ku TL kupita ku T2;Kenaka imalowa mu intercooler, imatulutsa kutentha kwa madzi ozizira pansi pa kupanikizika kosalekeza, ndipo kutentha kumatsikira ku TL;Kenako imapanikizidwa kukakamiza kofunikira P 3 kudzera pa silinda yothamanga kwambiri.The mpweya kutentha TL ndi T2 kulowa otsika-anzanu yamphamvu ndi mkulu-anzanu yamphamvu zili pa isotherm yemweyo 12 '3', ndi awiri psinjika njira 12 ndi 2 '3 kupatuka isotherm kutali.The single-siteji psinjika ndondomeko yofanana psinjika chiŵerengero p 3 / P 1 ndi 123 ", amene ali kutali kwambiri ndi isotherm 12 '3' kuposa psinjika magawo awiri, ndiko, kutentha kwambiri.Kuphatikizika kwa gawo limodzi kumafanana ndi dera 613 ″ 46, ntchito yoponderezedwa ya magawo awiri ndi yofanana ndi kuchuluka kwa madera 61256 ndi 52 ′ 345, ndipo ntchito yopulumutsidwa ndiyofanana ndi 2 ′ 23 ″ 32 '. .Zitha kuwoneka kuti kuponderezana kokhazikika kumatha kuchepetsa kutentha kwa utsi, kupulumutsa ntchito yopondereza ndikuwongolera magwiridwe antchito.

Ma piston air compressor ali ndi mitundu yambiri yamapangidwe.Malinga ndi kasinthidwe ka silinda, imatha kugawidwa m'mitundu yoyima, yopingasa, mtundu wa angular, mtundu wofananira komanso wotsutsana.Malingana ndi mndandanda wa psinjika, ukhoza kugawidwa m'magulu amodzi, mtundu wa magawo awiri ndi mitundu yambiri.Kutengera ndi momwe amakhazikitsira, imatha kugawidwa m'mitundu yam'manja ndi mtundu wokhazikika.Malinga ndi mode kulamulira, izo zikhoza kugawidwa mu kutsitsa mtundu ndi kuthamanga lophimba mtundu.Pakati pawo, njira yotulutsira yotsitsa imatanthawuza kuti pamene kupanikizika mu thanki yosungiramo mpweya kufika pamtengo wapatali, mpweya wa compressor susiya kuthamanga, koma umagwira ntchito mopanda mphamvu potsegula valve yotetezera.Kusagwira ntchito kumeneku kumatchedwa ntchito yotsitsa.Kuwongolera kosinthira kumatanthauza kuti kukakamiza mu tanki yosungiramo mpweya kukafika pamtengo wokhazikitsidwa, compressor ya mpweya imasiya kuthamanga.
