Isistimu yomoya ecindezelwe, ngomqondo omncane, yakhiwe imishini yomthombo womoya, izinto zokuhlanza umthombo womoya kanye namapayipi ahlobene.Ngomqondo obanzi, izingxenye ezisizayo zomoya, ama-actuator womoya, izingxenye zokulawula umoya, izingxenye ze-vacuum, njll. zonke ziyingxenye yesistimu yomoya ocindezelwe.Ngokuvamile, okokusebenza kwesiteshi se-compressor emoyeni kuwuhlelo lomoya olucindezelwe ngomqondo omncane.Isibalo esilandelayo sibonisa ishadi elijwayelekile lokugeleza kwesistimu yomoya ecindezelwe:
Impahla yomthombo womoya (i-compressor yomoya) imunca emkhathini, icindezela umoya osesimweni semvelo ibe umoya ocindezelwe onomfutho ophakeme, futhi isusa umswakama, uwoyela nokunye ukungcola emoyeni ocindezelwe ngemishini yokuhlanza.
Umoya emvelweni wakhiwe ngengxube yamagesi ahlukahlukene (O₂, N₂, CO₂… njll.), futhi umhwamuko ungomunye wawo.Umoya oqukethe inani elithile lomhwamuko ubizwa ngokuthi umoya omswakama, futhi umoya ongenawo umhwamuko ubizwa ngokuthi umoya owomile.Umoya osizungezile ungumoya onomswakama, ngakho-ke indawo yokusebenza ye-compressor yomoya iwumoya onomswakama ngokwemvelo.
Nakuba umhwamuko wamanzi womoya onomswakama umncane kakhulu, okuqukethwe kwawo kunethonya elikhulu ezintweni ezibonakalayo zomoya onomswakama.Kuhlelo lokuhlanza umoya ocindezelweyo, ukomiswa komoya ocindezelwe kungenye yezinto ezisemqoka.
Ngaphansi kwezimo ezithile zokushisa nokucindezela, okuqukethwe komhwamuko wamanzi emoyeni oswakeme (okungukuthi, ukuminyana komhwamuko wamanzi) kunqunyelwe.Emazingeni okushisa athile, lapho inani lomhwamuko wamanzi eliqukethwe lifinyelela izinga eliphezulu lokuqukethwe, umoya onomswakama ngalesi sikhathi ubizwa ngokuthi umoya ogcwele.Umoya oswakeme ongenawo ubuningi bomhwamuko wamanzi ubizwa ngokuthi umoya ongagcwalisiwe.
Ngaleso sikhathi lapho umoya ongagcwalisiwe uba umoya ogcwele, amaconsi amanzi awuketshezi azofingqa emoyeni onomswakama, obizwa ngokuthi “i-condensation”.Ukufingqa kuvamile.Isibonelo, umswakama womoya uphezulu ehlobo, futhi kulula ukwenza amaconsi amanzi ebusweni bepayipi lamanzi.Ekuseni kwasebusika, amaconsi amanzi azovela emafasiteleni engilazi abahlali.Konke lokhu kwenziwa ukupholiswa komoya oswakeme ngaphansi kwengcindezi engapheli.Lu imiphumela.
Njengoba kushiwo ngenhla, izinga lokushisa lapho umoya ongagcwalisiwe ufinyelela ukugcwala kwamanzi libizwa ngokuthi indawo yamazolo lapho ukucindezela okuyingxenye komhwamuko kugcinwa kungashintshi (okungukuthi, amanzi aphelele agcinwa engashintshi).Lapho izinga lokushisa lehla lifinyelela izinga lokushisa lamazolo, kuzoba “nokujiya”.
Iphuzu lamazolo omoya onomswakama alihlobene nje kuphela nezinga lokushisa, kodwa futhi lihlobene nenani lomswakama emoyeni oswakeme.Iphuzu lamazolo liphezulu namanzi amaningi, futhi indawo yamazolo iphansi futhi iphansi yamanzi.
Izinga lokushisa lamazolo linokusetshenziswa okubalulekile kubunjiniyela be-compressor.Isibonelo, lapho izinga lokushisa le-outlet le-compressor yomoya liphansi kakhulu, ingxube ye-oyela-gas izoncipha ngenxa yokushisa okuphansi emgqonyeni we-oil-gas, okuzokwenza amafutha okugcoba aqukethe amanzi futhi athinte umphumela wokugcoba.ngakho-ke.Izinga lokushisa le-outlet le-compressor yomoya kufanele lenziwe ukuthi lingabi ngaphansi kwezinga lokushisa lamazolo ngaphansi kwengcindezi eyingxenye ehambisanayo.
I-atmospheric dew point izinga lokushisa lendawo yamazolo ngaphansi kwengcindezi yomoya.Ngokufanayo, iphuzu lamazolo elicindezelayo libhekisela ekushiseni kwamazolo omoya wokucindezela.
Ubudlelwano obuhambisanayo phakathi kwephuzu lamazolo omfutho kanye nephuzu elivamile lamazolo lihlobene nesilinganiso sokucindezela.Ngaphansi kwephuzu lamazolo elicindezelayo, lapho isilinganiso sokucindezelwa sikhulu, sinciphisa iphuzu lamazolo elivamile elihambisanayo.
Umoya ocindezelwe ophuma ku-air compressor ungcolile.Izinto ezingcolisa kakhulu yilezi: amanzi (amaconsi amanzi aluketshezi, inkungu yamanzi kanye nomhwamuko wamanzi oyigesi), inkungu kawoyela egcotshwayo eyinsalela (amaconsi kawoyela wenkungu nomhwamuko kawoyela), ukungcola okuqinile (udaka lokugqwala, impushana yensimbi, izinhlawulo zenjoloba, izinhlayiya zetiyela nezinto zokuhlunga, impushana emihle yezinto zokuvala, njll.), ukungcola kwamakhemikhali ayingozi nokunye ukungcola.
Amafutha okugcoba awonakele azowohloka irabha, ipulasitiki, nezinto zokuvala, kubangele ukungasebenzi kahle kwamavalvu nemikhiqizo engcolisayo.Umswakama nothuli kuzodala izingxenye zensimbi namapayipi ukuthi kugqwale futhi kugqwale, kubangele izingxenye ezihambayo ukuba zibambeke noma ziguge, kubangele izingxenye zomoya ukuba zingasebenzi kahle noma zivuze umoya.Umswakama nothuli kuzophinde kuvimbe izimbobo ezidonsayo noma izikrini zokuhlunga.Ngemva kokuba iqhwa libangela ukuba ipayipi libe yiqhwa noma liqhekeke.
Ngenxa yekhwalithi yomoya ephansi, ukwethembeka kanye nempilo yesevisi yesistimu ye-pneumatic kuncipha kakhulu, futhi ukulahlekelwa okubangelwa ngokuvamile kuvame ukudlula kakhulu izindleko nezindleko zokunakekelwa kwedivayisi yokwelapha yomthombo womoya, ngakho-ke kuyadingeka ngempela ukukhetha kahle ukwelashwa komthombo womoya. uhlelo.
Yimiphi imithombo eyinhloko yomswakama emoyeni ocindezelweyo?
Umthombo oyinhloko womswakama emoyeni ocindezelwe umhwamuko wamanzi umuncwa i-compressor yomoya kanye nomoya.Ngemva kokuba umoya oswakeme ungene ku-compressor yomoya, inani elikhulu lomhwamuko wamanzi liyakhama emanzini awuketshezi phakathi nenqubo yokucindezelwa, okuzonciphisa kakhulu umswakama ohlobene womoya ocindezelwe ekuphumeni kwe-compressor yomoya.
Isibonelo, lapho ingcindezi yesistimu ingu-0.7MPa kanye nomswakama ohlobene komoya ohogeliwe ungama-80%, nakuba umoya ocindezelwe ophuma ku-compressor womoya ugcwele ngaphansi kwengcindezi, uma uguqulelwa esimweni somoya womoya ngaphambi kokucindezelwa, umswakama wawo ohlobene kuphela 6 ~ 10%.Okusho ukuthi, umswakama womoya ocindezelwe wehliswe kakhulu.Nokho, njengoba izinga lokushisa liyehla kancane kancane epayipini legesi nasezintweni zegesi, inani elikhulu lamanzi awuketshezi lizoqhubeka nokujiya emoyeni ocindezelweyo.
Kubangelwa kanjani ukungcoliswa kwamafutha emoyeni ocindezelwe?
Amafutha okugcoba e-compressor yomoya, umhwamuko kawoyela namaconsi kawoyela amisiwe emoyeni ozungezile kanye namafutha okugcoba ezingxenye zomoya ohlelweni yimithombo eyinhloko yokungcoliswa kwamafutha emoyeni ocindezelwe.
Ngaphandle kwama-centrifugal and diaphragm air compressors, cishe wonke ama-compressor komoya asetshenziswayo njengamanje (okuhlanganisa ama-compressor komoya agcotshiwe ahlukahlukene anganamafutha) azoba nowoyela ongcolile (amaconsi kawoyela, inkungu kawoyela, umhwamuko kawoyela kanye ne-carbon fission) epayipini legesi.
Izinga lokushisa eliphezulu legumbi lokucindezela le-compressor yomoya lizokwenza ukuthi cishe u-5% ~ 6% wamafutha ahwamuke, aqhekeze futhi akhiphe i-oxidize, futhi afakwe odongeni lwangaphakathi lwepayipi lokucindezela umoya ngendlela yefilimu ye-carbon ne-varnish, futhi ingxenye yokukhanya izomiswa ngendlela ye-steam kanye ne-micro Ifomu lendaba ilethwa ohlelweni ngomoya ocindezelweyo.
Ngamafuphi, kumasistimu angadingi izinto zokugcoba ngesikhathi sokusebenza, wonke amafutha nezinto zokugcoba ezixutshwe emoyeni ocindezelweyo osetshenzisiwe zingabhekwa njengezinto ezingcoliswe uwoyela.Kuzinhlelo ezidinga ukwengeza izinto zokugcoba ngesikhathi somsebenzi, wonke upende ophikisana nokugqwala kanye namafutha e-compressor aqukethwe emoyeni ocindezelwe kubhekwa njengokungcola kokungcola kwamafutha.
Ukungcola okuqinile kungena kanjani emoyeni ocindezelwe?
Imithombo eyinhloko yokungcola okuqinile emoyeni ocindezelwe yile:
①Umkhathi ozungezile uxutshwe nokungcola okuhlukahlukene kosayizi bezinhlayiyana abahlukene.Ngisho noma imbobo yokudonsa i-air compressor ifakwe isihlungi somoya, ngokuvamile ukungcola "kwe-aerosol" okungaphansi kuka-5 μm kusengangena ku-compressor yomoya ngomoya ohogeliwe, oxutshwe namafutha namanzi epayipini lokukhipha umoya phakathi nenqubo yokucindezelwa.
②Lapho i-compressor yomoya isebenza, ukungqubuzana nokushayisana phakathi kwezingxenye ezihlukahlukene, ukuguga nokuwa kwezimpawu, kanye ne-carbonization kanye nokuqhekeka kwamafutha okugcoba ekushiseni okuphezulu kuzodala izinhlayiya eziqinile njengezinhlayiya zensimbi, uthuli lwerabha kanye ne-carbonaceous. i-fission ezolethwa epayipini legesi.
