Abantu abaninzi bayazi ukuba izigaba ezimbini ze-compressor zifanelekile kwimveliso yoxinzelelo oluphezulu, kwaye isigaba sokuqala sifanelekile kwimveliso enkulu yegesi. Ngamanye amaxesha, kuyimfuneko ukwenza ucinezelo olungaphezulu kweebini. Kutheni ufuna i-compressed graded?
Xa uxinzelelo olusebenzayo lwegesi lufuneka ukuba lube luphezulu, ukusetyenziswa kokunyanzeliswa kwesigaba esisodwa akukona nje uqoqosho, kodwa ngamanye amaxesha akunakwenzeka, kwaye kufuneka kusetyenziswe ukunyanzeliswa kwamanqanaba amaninzi. Ukunyanzeliswa kwamanqanaba amaninzi kukuqalisa igesi ukusuka ekuphefumleleni, kwaye emva kokunyuswa okuninzi ukufikelela kuxinzelelo olufunekayo lokusebenza.

1. Gcina ukusetyenziswa kwamandla

Ngokunyanzeliswa kwamanqanaba amaninzi, i-cooler ingacwangciswa phakathi kwezigaba, ukwenzela ukuba igesi ecinezelweyo ifakwe kwi-isobaric yokupholisa emva kokunyanzeliswa kwesigaba esisodwa ukunciphisa ubushushu, kwaye ingena kwi-cylinder yesigaba esilandelayo. Ubushushu buyancipha kwaye ubuninzi bunyukile, ukuze kube lula ukuqhubela phambili ukucinezela, okunokugcina kakhulu ukusetyenziswa kwamandla xa kuthelekiswa noxinzelelo lwexesha elinye. Ke ngoko, phantsi koxinzelelo olufanayo, indawo yokusebenza yoxinzelelo lwamanqanaba amaninzi ingaphantsi kwaleyo yoxinzelelo lwenqanaba elinye. Okukhona inani lezigaba, kokukhona ukusetyenziswa kwamandla ngakumbi kwaye kufutshane kuxinzelelo lwe-isothermal.
Qaphela: Icompressor yomoya ye-oyile-injected screw air compressor isondele kakhulu kwinkqubo yokushisa eqhubekayo. Ukuba uqhubeka ucinezela kwaye uqhubeke upholisa emva kokufikelela kwindawo egcweleyo, amanzi adibeneyo aya kuncitshiswa. Ukuba amanzi adibeneyo angena kwi-oil-air separator (itanki yeoli) kunye nomoya oxinyiweyo, iya kumisa ioli yokupholisa kwaye ichaphazele umphumo wokuthambisa. Ngokunyuka okuqhubekayo kwamanzi adibeneyo, inqanaba leoli liya kuqhubeka nokunyuka, kwaye ekugqibeleni ioli yokupholisa iya kungena kwinkqubo kunye nomoya oxinyiweyo, ungcolise umoya oxinzelelweyo kwaye ubangele imiphumo emibi kwinkqubo.
Ngoko ke, ukwenzela ukukhusela ukuveliswa kwamanzi adibeneyo, iqondo lokushisa kwigumbi loxinzelelo alikwazi ukuba liphantsi kakhulu kwaye kufuneka libe phezulu kunokushisa kwe-condensation. Umzekelo, icompressor yomoya enoxinzelelo lwe-exhaust ye-11 bar (A) ineqondo lobushushu le-68 °C. Xa iqondo lobushushu kwigumbi lokucinezela lingaphantsi kwama-68 °C, amanzi ajiyileyo aya kuncitshiswa. Ngoko ke, ukushisa kweqondo lokushisa kwe-oyile-injected screw air compressor ayikwazi ukuba phantsi kakhulu, oko kukuthi, ukusetyenziswa kwe-isothermal compression kwi-oil-injected screw air compressor inqunyelwe ngenxa yengxaki yamanzi adibeneyo.

2. Ukuphucula ukusetyenziswa kwevolumu

Ngenxa yezizathu ezithathu zokwenziwa, ukufakwa kunye nokusebenza, umthamo wokukhutshwa kwi-cylinder usoloko ungenakuthintelwa, kwaye umthamo wokucoca awuncitshi ngokuthe ngqo umthamo osebenzayo we-cylinder, kodwa kunye negesi eseleyo yoxinzelelo oluphezulu kufuneka yandiswe kuxinzelelo lokufunxa. , i-cylinder inokuqalisa ukukhupha igesi entsha, elingana nokunciphisa ngakumbi umthamo osebenzayo we-cylinder.
Akunzima ukuqonda ukuba ukuba umlinganiselo woxinzelelo mkhulu, igesi eseleyo kwivolumu yokucoca iya kwanda ngokukhawuleza, kwaye umthamo osebenzayo we-cylinder uya kuba mncinci. Kwiimeko ezigqithisileyo, nasemva kokuba igesi kumthamo wokucoca yandisiwe ngokupheleleyo kwi-cylinder, uxinzelelo alukho ngaphantsi koxinzelelo lokufunxa. Ngeli xesha, ukutsala kunye nokukhupha akukwazi ukuqhubeka, kwaye umthamo osebenzayo we-cylinder uba zero. Ukuba ucinezelo lwamanqanaba amaninzi lusetyenzisiwe, umlinganiselo wokunyanzeliswa kwenqanaba ngalinye lincinci kakhulu, kwaye irhasi eshiyekileyo kumthamo wococeko iyanda kancinane ukufikelela kuxinzelelo lokufunxa, nto leyo eyandisa ngokwendalo umthamo osebenzayo wesilinda, ngaloo ndlela iphucula izinga lokusetyenziswa kwe-cylinder. umthamo wesilinda.

3. Nciphisa ubushushu bokukhupha

Ukushisa kwegesi yokukhupha i-compressor kwandisa ngokunyuka komlinganiselo wokunyanzeliswa. Ukuphakama komlinganiselo woxinzelelo, kokukhona ubushushu begesi yokuphuma buphezulu, kodwa ubushushu obugqithisileyo berhasi yokukhupha ayivumelekanga. Oku kungenxa yokuba: kwi-oyile-lubricated compressor, ukushisa kweoli yokuthambisa kuya kunciphisa i-viscosity kwaye kwandise ukunxiba. Xa iqondo lokushisa liphakama kakhulu, kulula ukwenza iidiphozithi zekhabhoni kwi-cylinder kunye nevalve, ukunyusa ukunxiba, kunye nokugqabhuka. Ngenxa yezizathu ezahlukahlukeneyo, iqondo lobushushu lokukhupha lilinganiselwe kakhulu, ngoko ke kufuneka kusetyenziswe ukunyanzeliswa kwamanqanaba amaninzi ukuze kuncitshiswe iqondo lobushushu lokuphuma.
Qaphela: Ukunyanzeliswa kwesiteji kunokunciphisa ubushushu bombhobho we-screw air compressor, kwaye kwangaxeshanye, kunokwenza inkqubo ye-thermal yecompressor yomoya ibe kufutshane noxinzelelo lobushushu rhoqo kangangoko kunokwenzeka ukufezekisa umphumo wokonga amandla, kodwa ayigqibelelanga. Ngokukodwa kwi-oyile-injected screw air compressors kunye ne-exhaust pressure ye-13 bar okanye ngaphantsi, ngenxa ye-oyile yokupholisa yobushushu obuphantsi obufakwe ngexesha lenkqubo yoxinzelelo, inkqubo yoxinzelelo sele isondele kwinkqubo yokushisa rhoqo, kwaye akukho mfuneko ucinezelo lwesibini. Ukuba ukunyanzeliswa okucwangcisiweyo kwenziwa ngesiseko sokupholisa inaliti yeoli, isakhiwo sinzima, iindleko zokuvelisa zonyuka, kunye nokumelana nokuhamba kwegesi kunye nokusetyenziswa kwamandla okongeziweyo kuye kwanda, okuyilahleko encinci. . Ukongezelela, ukuba iqondo lokushisa liphantsi kakhulu, ukubunjwa kwamanzi adibeneyo ngexesha lenkqubo yoxinzelelo kuya kubangela ukuwohloka kwenkqubo yenkqubo, okukhokelela kwimiphumo emibi.

4. Nciphisa amandla erhasi asebenza kwintonga yepiston

Kwicompressor yepiston, xa umlinganiselo woxinzelelo uphezulu kwaye ucinezelo lwenqanaba elinye lusetyenziswa, i-cylinder diameter inkulu, kwaye uxinzelelo lwegesi lokugqibela lusebenza kwindawo enkulu yepiston, kwaye igesi kwipiston inkulu. Ukuba ukunyanzeliswa kwamanqanaba amaninzi kwamkelwa, amandla egesi asebenza kwipiston angancitshiswa kakhulu, ngoko ke kunokwenzeka ukwenza umatshini ulula kwaye uphucule ukusebenza kakuhle komatshini.
Ewe kunjalo, ukunyanzeliswa kwamanqanaba amaninzi akulona ngcono. Ngenxa yokuba inani lezigaba, ubuninzi besakhiwo se-compressor, ukwanda kobukhulu, ubunzima kunye neendleko; ukwanda kwe-gas passage, ukwanda kwelahleko yoxinzelelo lwe-valve yegesi kunye nolawulo, njl., ngoko ngamanye amaxesha inani lezigaba, uqoqosho olusezantsi, ngakumbi inani lezigaba. Ngeendawo ezininzi ezihambayo, ithuba lokungaphumeleli liya kwanda. Ukuchaneka koomatshini nako kuya kuncitshiswa ngenxa yokwanda kwengxabano.
