Ama-screw air compressors ama-compressor alungile, afinyelela inhloso yokucindezelwa kwegesi ngokunciphisa kancane kancane umthamo wokusebenza.
Ivolumu yokusebenza ye-screw air compressor yenziwe ngepheya lama-rotors abekwe ngokuhambisana nomunye futhi ahlanganyele nomunye kanye ne-chassis ebamba leli pheya lama-rotors.Lapho umshini usebenza, amazinyo ama-rotor amabili afakwe ezindongeni zomunye nomunye, futhi njengoba i-rotor ijikeleza, amazinyo afakwe ku-cogs yomunye ahamba aze afike ekugcineni kwe-exhaust, ukuze ivolumu evalwe amazinyo elinye iyancipha kancane kancane, futhi ukucindezela kancane kancane kuyanda kuze kube yilapho kufinyelelwa ukucindezela okudingekayo.Lapho ukucindezela kufinyelelwa, ama-cogs axhumana ne-exhaust port ukuze afinyelele ukuphuma.
Ngemuva kokuthi i-alveolar ifakwe amazinyo omphikisi ahlangene nayo, kwakheka izikhala ezimbili ezihlukaniswe ngamazinyo.I-alveolar eduze nokuphela kokumunca ivolumu yokudonsa, futhi eseduze nendawo yokukhipha ivolumu yegesi ecindezelweyo. Ngokusebenza kwe-compressor, amazinyo e-rotor ephikisanayo afakwe ku-cogging ahamba ngasekugcineni kokukhipha, ngakho-ke. ukuthi ivolumu yokumunca iyaqhubeka nokukhula futhi umthamo wegesi ocindezelwe uyaqhubeka nokuncipha, ngaleyo ndlela uqaphela inqubo yokudonsa nokucindezela ekubambeni ngakunye.Lapho umfutho wegesi wegesi ocindezelwe ku-cogging ufinyelela ukucindezela kokukhipha umoya odingekayo, i-cogging ivele ixhumane ne-vent futhi inqubo yokukhipha umoya iqala. ziyaphindwa, ukuze i-compressor ikwazi ukuhogela ngokuqhubekayo, icindezele futhi ikhiphe.
Isimiso sokusebenza kanye nesakhiwo se-screw compressor:
1. Inqubo yokumunca: Imbobo yokudonsa ohlangothini lokudonsa lohlobo lwesikulufu kufanele iklanywe ukuze igumbi lokuminyanisa lihogelwe ngokugcwele.I-screw air compressor ayinalo iqembu le-valve yokungenisa kanye ne-exhaust.Ukungena kulungiswa kuphela ngokuvula nokuvalwa kwe-valve yokulawula.Lapho i-rotor ijikeleza, isikhala se-toove groove ye-rotor eyinhloko kanye ne-axiliary idluliselwa ekuvuleni kodonga lokungenisa umoya, isikhala z * sikhulu, ngalesi sikhathi isikhala se-tooth groove se-rotor sixhumana nomoya wamahhala womoya. i-inlet, ngoba wonke umoya osemseleni wezinyo ukhishwa ngesikhathi sokuphuma, futhi i-toove groove isesimweni se-vacuum ekupheleni kokukhipha.Uma idluliselwa endaweni yokungenisa umoya, isikhala u-z* sikhulu.Ngalesi sikhathi, isikhala sezinyo le-rotor sixhumana nomoya wamahhala we-air inlet, ngoba wonke umoya osemseleni wezinyo ukhishwa ngesikhathi sokukhipha.Ekupheleni kwe-exhaust, i-toove groove isesimweni se-vacuum.Uma idluliselwa endaweni yokungena komoya, Umoya wangaphandle udonswa ngaphakathi futhi ugeleze nge-axially ungene emgodini wezinyo le-rotor eyinhloko kanye ne-axiliary. I-air inlet side ye-rotor isusiwe ekungeneni komoya kwe-chassis, futhi umoya ophakathi kwemigodi yezinyo uvaliwe.
2. Inqubo yokubeka uphawu nokudlulisa: Ekupheleni kokumunca i-rotor eyinhloko kanye ne-axiliary, i-toove groove ye-rotor eyinhloko kanye ne-axiliary kanye ne-chassis ivaliwe.Ngalesi sikhathi, umoya uvalekile emseleni wamazinyo futhi awusaphumi, okungukuthi, [inqubo yokuvala uphawu].Ama-rotor amabili ayaqhubeka nokuzungeza, futhi iziqongo zawo zamazinyo nezinyosi ziqondana ekugcineni kokumunca, futhi indawo engaphezulu ye-anastomosis. kancane kancane iqhubekela phambili ekuphumeni.
3. Ukucindezelwa kanye nenqubo yokujova uwoyela: Phakathi nenqubo yokudlulisa, i-meshing surface kancane kancane ithuthela ekugcineni kokukhipha, okungukuthi, umsele wezinyo phakathi kwe-meshing surface kanye ne-exhaust port kancane kancane uyancipha, futhi igesi esemseleni wezinyo iyacindezelwa kancane kancane. futhi ingcindezi iyanda.Lena [inqubo yokucindezela]. Ngesikhathi esifanayo nokucindezela, amafutha okugcoba nawo afafazwe ekamelweni lokucindezela futhi ahlanganiswe negesi yekamelo ngenxa yomehluko wokucindezela.
4. Inqubo yokukhipha umoya: Lapho i-meshing end face ye-screw air compressor maintenance rotor idluliswa ukuze ixhumane ne-chassis ephumayo, (ngalesi sikhathi ukucindezela kwegesi ecindezelwe kungu-z*phezulu) igesi ecindezelwe iqala ukuphuma. kuze kube yilapho i-meshing surface ye-tooth peak kanye ne-toove groove ihanjiswa ebusweni bokuphela kokukhipha.Ngalesi sikhathi, isikhala se-tooth groove phakathi kwe-meshing surface ye-rotors ezimbili kanye ne-port yokukhipha i-chassis ingu-zero, okungukuthi, (inqubo yokukhipha) iphelile.Ngesikhathi esifanayo, ubude bomgodi wezinyo phakathi kwe-meshing surface ye-rotor kanye ne-air inlet ye-chassis kufinyelela ku-z* ubude, futhi inqubo yokumunca iyaqhubeka.
I-Screw air compressors ihlukaniswe yaba: uhlobo oluvulekile, uhlobo oluvalwe kancane, uhlobo oluvalwe ngokugcwele
1. I-screw compressor evalwe ngokugcwele: umzimba wamukela ikhwalithi ephezulu, isakhiwo sensimbi ephansi ene-porosity ene-deformation encane yokushisa;umzimba wamukela isakhiwo esinezindonga ezimbili nge-exhaust passage, amandla aphezulu kanye nomphumela omuhle wokunciphisa umsindo;amandla angaphakathi nangaphandle omzimba alinganisela ngokuyisisekelo, futhi ayikho ingozi yokucindezela okuphezulu okuvulekile nokuvalwe kancane;igobolondo iyisakhiwo sensimbi esinamandla amakhulu, ukubukeka okuhle kanye nesisindo esincane.Isakhiwo esimile siyamukelwa, futhi i-compressor ithatha indawo encane, ehambisana nokuhlelwa kwamakhanda amaningi we-chiller;ukuthwala okuphansi kucwiliswa ethangini lamafutha, futhi ukuthwala kugcotshwe kahle;amandla e-axial we-rotor ancishiswa ngo-50% uma kuqhathaniswa nohlobo oluhlanganisiwe noluvulekile (umphumela wokulinganisa we-motor shaft ohlangothini lokukhipha);abukho ubungozi be-cantilever enezingqimba, ukuthembeka okuphezulu;gwema umthelela we-screw rotor, i-spool valve, nesisindo se-motor rotor ekunembeni okufanayo, futhi uthuthukise ukuthembeka;inqubo yokuhlanganisa okuhle.Umklamo oqondile wesikulufu ngaphandle kwepompo yamafutha wenza ukuba i-compressor isebenze noma ime ngaphandle kokuntuleka kwamafutha.I-bearing ephansi icwiliswa ethangini likawoyela lilonke, futhi i-apper bearing ithatha ukucindezela okuhlukile kokunikezwa kwamafutha;izidingo zengcindezi yomehluko wesistimu ziphansi.Esimeni esiphuthumayo, umsebenzi wokuvikela ukugcotshwa kwe-bearing ugwema ukuntuleka kokugcoba uwoyela we-bearing, okulungele ukuvulwa kweyunithi phakathi nenkathi yenguquko.Okubi: Ukusetshenziswa kokupholisa i-exhaust, i-motor is at the exhaust port, okungaba lula ukuthi ikhoyili yemoto ishise;ngaphezu kwalokho, ukwehluleka akukwazi ukukhishwa ngesikhathi.
2. I-screw compressor evalwe kancane
I-motor epholile nge-spray, izinga lokushisa eliphansi le-motor, impilo ende;I-compressor evulekile isebenzisa umoya ukupholisa injini, izinga lokushisa lokusebenza kwemoto liphakeme, elithinta impilo yemoto, futhi indawo yokusebenza yegumbi lekhompyutha impofu;ukusetshenziswa kwe-exhaust ukupholisa imoto, izinga lokushisa lokusebenzisa imoto liphezulu kakhulu, impilo yemoto ifushane.Ngokujwayelekile, uwoyela wangaphandle mkhulu ngobukhulu, kodwa ukusebenza kahle kuphezulu kakhulu;amafutha eyakhelwe ngaphakathi ahlanganiswe ne-compressor, encane ngobukhulu, ngakho-ke umphumela umpofu kakhulu.Umphumela wokuhlukaniswa kwamafutha wesibili ungafinyelela ku-99.999%, ongaqinisekisa ukugcoba okuhle kwe-compressor ngaphansi kwezimo ezihlukahlukene zokusebenza. I-plunger semi-enclosed screw compressor ishayelwa igiya ukukhulisa isivinini, ijubane liphezulu (cishe 12,000 rpm), ukugqokwa kukhulu, futhi ukwethembeka kubi.
Ezintathu, i-screw compressor evulekile
Izinzuzo zamayunithi ohlobo oluvulekile yilezi: 1) I-compressor ihlukaniswe ne-motor, ukuze i-compressor ibe nohlu olubanzi lwezinhlelo zokusebenza;2) I-compressor efanayo ingasetshenziswa kumafriji ahlukene.Ngaphezu kwama-halogenated hydrocarbon refrigerants, i-ammonia ingasetshenziswa njengesiqandisi ngokushintsha izinto zezingxenye ezithile;3) Ngokweziqandisi ezihlukene kanye nezimo zokusebenza, amamotho anamandla ahlukene angasetshenziswa.Ububi obuyinhloko bamayunithi ohlobo oluvulekile yilezi: (1) Isigxivizo se-shaft kulula ukuvuza, okubuye kube into esetshenziswa njalo ukugcinwa ngabasebenzisi;(2) I-motor ehlomile ijikeleza ngesivinini esikhulu, umsindo wokugeleza komoya mkhulu, futhi umsindo we-compressor ngokwawo nawo mkhulu, othinta imvelo;(3) Kuyadingeka ukumisa isihlukanisi sikawoyela esihlukile, isipholile sikawoyela kanye nezinye izingxenye zesistimu kawoyela eziyinkimbinkimbi, iyunithi inkulu, ayilungele ukusetshenziswa nokuyigcina.
