Okuyisisekelo
① Ukuhlaziywa komgomo wokusebenza we-centrifugal air compressor
I-centrifugal air compressor iqhutshwa i-impeller ukuze ijikeleze igesi ngesivinini esikhulu, ukuze igesi ikhiqize amandla e-centrifugal.Ngenxa yokugeleza kokusabalalisa kwegesi ku-impeller, izinga lokugeleza nokucindezela kwegesi ngemva kokudlula ku-impeller kuyanda, futhi umoya ocindezelwe ukhiqizwa ngokuqhubekayo.I-centrifugal air compressor yakhiwa ikakhulukazi izingxenye ezimbili: i-rotor kanye ne-stator.I-rotor ihlanganisa i-impeller kanye ne-shaft.Kukhona ama-blades ku-impeller, ngaphezu kwe-balance disc kanye nengxenye ye-shaft seal.Umzimba oyinhloko we-stator yi-casing (i-cylinder), futhi i-stator nayo ihlelwe nge-diffuser, i-bend, idivayisi ye-reflux, ipayipi yokungena emoyeni, ipayipi yokukhipha umoya, nezinye izimpawu ze-shaft.Isimiso sokusebenza se-compressor ye-centrifugal ukuthi lapho i-impeller ijikeleza ngesivinini esikhulu, igesi ijikeleza nayo.Ngaphansi kwesenzo samandla we-centrifugal, igesi iphonswa ku-diffuser ngemuva, futhi indawo ye-vacuum yakheka ku-impeller.Ngalesi sikhathi, igesi fresh ngaphandle ku impeller.I-impeller ijikeleza ngokuqhubekayo, futhi igesi idonswa ngokuqhubekayo futhi iphonswe ngaphandle, ngaleyo ndlela igcine ukugeleza okuqhubekayo kwegesi.
I-Centrifugal air compressors incike ekushintsheni kwamandla e-kinetic ukukhulisa ukucindezela kwegesi.Lapho i-rotor enama-blades (okungukuthi, isondo elisebenzayo) ijikeleza, ama-blades ashayela igesi ukuze ajikeleze, adlulisele umsebenzi kugesi, futhi enze igesi ithole amandla e-kinetic.Ngemuva kokungena engxenyeni ye-stator, ngenxa yokwandiswa okuncane kwe-stator, ikhanda lokucindezela kwamandla wejubane liguqulwa libe yingcindezi edingekayo, ijubane liyancipha, futhi ingcindezi iyanda.Ngesikhathi esifanayo, isebenzisa umphumela oqondisayo wengxenye ye-stator ukuze ingene esigabeni esilandelayo se-impeller ukuze iqhubeke nokukhuphula, futhi ekugcineni ikhiphe ku-volute..Ku-compressor ngayinye, ukuze kuzuzwe ingcindezi edingekayo yokuklama, i-compressor ngayinye inenani elihlukile lezigaba nezigaba, futhi iqukethe ngisho namasilinda amaningana.
② Inqubo yokuvuselela ukushisa kwe-centrifugal air compressor
Ama-Centrifuges ngokuvamile adlula ezigabeni ezintathu zokucindezelwa.Izigaba zokuqala nezesibili zomoya ocindezelweyo azifanelekile ukubuyiswa kokushisa kwemfucuza ngenxa yethonya lokushisa lokuphuma nokucindezela.Ngokuvamile, ukubuyiswa kokushisa kwemfucuza kwenziwa esigabeni sesithathu somoya ocindezelwe, futhi i-air aftercooler idinga ukwengezwa, njengoba kuboniswe kuMfanekiso 8. Kubonisa ukuthi lapho ukuphela okushisayo kungadingi ukusebenzisa ukushisa, umoya ocindezelweyo upholiswa ngaphandle kokupholisa umoya. ezithinta ukusebenza kohlelo.
Enye indlela yokubuyisela ukushisa kwemfucuza yama-compressor omoya apholile amanzi
Kuma-compressor omoya afana nemishini yesikulufu ejovwe ngamanzi epholile ngamanzi, imishini yezikulufu ezingenawo uwoyela, nama-centrifuges, ngaphezu kokubuyiswa kokushisa kwemfucuza kokuguqulwa kwesakhiwo sangaphakathi, kungenzeka futhi ukuguqula ngokuqondile ipayipi lamanzi okupholisa ukuze kutholakale imfucuza. ukushisa ngaphandle kokushintsha isakhiwo somzimba.Recycle.
Ngokufaka iphampu yesibili epayipini lokuphuma kwamanzi okupholisa le-compressor yomoya, amanzi okupholisa angeniswa engxenyeni eyinhloko yepompo yokushisa yomthombo wamanzi, futhi inzwa yokushisa ekungeneni kweyunithi evaporator eyinhloko ilungisa ugesi ngezindlela ezintathu. i-valve elawulayo ngesikhathi sangempela ukulawula izinga lokushisa lokungena kwe-evaporator endaweni ethile.Ngevelu egxilile, amanzi ashisayo ku-50~55°C angakhiqizwa ngeyunithi yepompo yokushisa yomthombo wamanzi.
Uma singekho isidingo samanzi ashisayo ezinga eliphezulu lokushisa, isishintshi sokushisa sepuleti singaphinda sixhunywe kuchungechunge kumjikelezo wamanzi okupholisa ajikelezayo we-compressor yomoya.Amanzi okupholisa asezingeni eliphezulu ashintshanisa ukushisa namanzi athambile asuka ethangini lamanzi athambile, angagcini nje ukunciphisa izinga lokushisa langaphakathi lamanzi, kodwa futhi andisa izinga lokushisa langaphandle lamanzi.
Amanzi ashisayo agcinwa ethangini lokugcina amanzi ashisayo, bese ethunyelwa kunethiwekhi yokushisisa ukuze asetshenziswe lapho kudingeka khona umthombo wokushisa ophansi.
