Xa i-piston ebuyiselayo kwi-cylinder ihambela ngasekunene, uxinzelelo olukwigumbi lasekhohlo lepiston kwi-cylinder lingaphantsi koxinzelelo lwe-atmospheric PA, ivalve yokufunxa iyavulwa, kwaye umoya wangaphandle ufunxelwe kwi-cylinder.Le nkqubo ibizwa ngokuba yinkqubo yoxinzelelo.Xa uxinzelelo kwi-cylinder luphezulu kunoxinzelelo lwe-P kumbhobho womoya ophumayo, i-valve yokukhupha ivula.Umoya ocinezelweyo uthunyelwa kumbhobho wokuhambisa igesi.Le nkqubo ibizwa ngokuba yi-exhaust process.Intshukumo ephindaphindayo yepiston yenziwa yi-crank slider mechanism eqhutywa yinjini.Intshukumo ejikelezayo yekhrenki iguqulwa ibe kukutyibilika - intshukumo ephindaphindayo yepiston.

Icompressor enesi sakhiwo ihlala inomthamo oseleyo ekupheleni kwenkqubo yokukhupha.Kwi-suction elandelayo, umoya oxinyiweyo kumthamo oseleyo uya kwanda, ukwenzela ukunciphisa umthamo womoya ophefumlelweyo, ukunciphisa ukusebenza kakuhle kunye nokwandisa umsebenzi wokuxinzelela.Ngenxa yobukho bomthamo oseleyo, ubushushu buyanda ngokukhawuleza xa umlinganiselo wokunyanzeliswa ukhula.Ke ngoko, xa uxinzelelo lwemveliso luphezulu, ukunyanzeliswa kwesiteji kuya kwamkelwa.Ukunyanzeliswa kwenqanaba kunokunciphisa ubushushu bokukhupha, gcina umsebenzi woxinzelelo, ukuphucula ukusebenza kakuhle kwevolumetric kunye nokunyusa umthamo wokukhupha igesi ecinezelweyo.

Umzobo we-1 ubonisa i-compressor yomoya we-piston yenqanaba elilodwa, esetyenziswa ngokuqhelekileyo kwi-0 3 - 0.I-7 MPa inkqubo yoluhlu loxinzelelo.Ukuba uxinzelelo lwe-air compressor yenqanaba elinye lepiston ludlula i-0 6Mpa, izalathisi ezahlukeneyo zokusebenza ziya kuhla kabukhali, ngoko ke ucinezelo lwe-multistage luhlala lusetyenziselwa ukuphucula uxinzelelo lwemveliso.Ukuze kuphuculwe ukusebenza kakuhle kunye nokunciphisa ubushushu bomoya, ukupholisa okuphakathi kuyafuneka.Kwizixhobo ze-piston air compressor kunye noxinzelelo lwamanqanaba amabini, uxinzelelo lomoya luyanda ukusuka kwi-P1 ukuya kwi-P2 emva kokudlula kwi-cylinder ephantsi, kwaye ubushushu buyanda ukusuka kwi-TL ukuya kwi-T2;Emva koko igeleza kwi-intercooler, ikhuphe ukushisa kumanzi okupholisa phantsi koxinzelelo oluqhubekayo, kwaye iqondo lokushisa liyehla kwi-TL;Emva koko ixinzelelwe kuxinzelelo olufunekayo lwe-P 3 nge-cylinder yoxinzelelo oluphezulu.Amaqondo obushushu omoya TL kunye T2 ingena cylinder low-pressure kunye cylinder high-uxinzelelo zibekwe kwi isotherm efanayo 12 '3', kunye neenkqubo zokucinezela ezimbini 12 kunye 2 '3 aphambuke isotherm hayi kude.Inkqubo yokunyanzeliswa kwenqanaba elinye lomlinganiselo ofanayo woxinzelelo lwe-p 3 / P 1 yi-123 ", ekude kakhulu kwi-isotherm 12 "3" kunoxinzelelo lwezigaba ezimbini, oko kukuthi, ubushushu buphezulu kakhulu.Umsebenzi wokusetyenziswa koxinzelelo lwenqanaba elinye ulingana nommandla 613 ″ 46, umsebenzi wokusetyenziswa koxinzelelo lwenqanaba ezibini ulingana nesixa sendawo 61256 kunye ne52 ′ 345, kwaye umsebenzi ogciniweyo ulingana ne-2 ′ 23 ″ 32 '. .Ingabonwa ukuba ukunyanzeliswa kwenqanaba kunokunciphisa ubushushu bombhobho, konga umsebenzi woxinzelelo kunye nokuphucula ukusebenza kakuhle.

Iicompressor zomoya zepiston zineendlela ezininzi zolwakhiwo.Ngokwendlela yoqwalaselo ye-cylinder, inokwahlulwa ibe luhlobo oluthe nkqo, uhlobo oluthe tyaba, uhlobo lwe-angular, uhlobo lwe-symmetrical balance kunye nohlobo oluchasiweyo.Ngokutsho koluhlu lokunyanzeliswa, lunokwahlulwa lube luhlobo olulodwa lwenqanaba, uhlobo oluphindwe kabini kunye nodidi lwezigaba ezininzi.Ngokwendlela yokumisela, inokwahlulwa ibe yintlobo yeselula kunye nohlobo olusisigxina.Ngokwendlela yokulawula, inokwahlulwa ibe yintlobo yokukhulula kunye noxinzelelo lokutshintsha.Phakathi kwabo, imodi yokulawula ukukhulula ithetha ukuba xa uxinzelelo kwitanki yokugcina umoya lufikelela kwixabiso elimiselweyo, i-compressor yomoya ayiyeki ukusebenza, kodwa iqhuba umsebenzi ongaxinzekanga ngokuvula i-valve yokukhusela.Le meko yokungenzi nto ibizwa ngokuba ngumsebenzi wokothula.Imowudi yokulawula uxinzelelo ithetha ukuba xa uxinzelelo kwitanki yokugcina umoya lufikelela kwixabiso elimiselweyo, i-compressor yomoya iya kuyeka ngokuzenzekelayo ukusebenza.
