Ama-screw air compressors angama-compressor okuhambisa umoya amahle, afinyelela injongo yokucindezelwa kwegesi ngokunciphisa kancane kancane ivolumu yokusebenza.
Umthamo osebenzayo we-screw air compressor wakhiwe ngama-cog amabili ama-rotor abekwe eceleni komunye nomunye futhi axhumene kanye ne-chassis evumela la ma-rotor amabili. Lapho umshini usebenza, amazinyo ama-rotor amabili afakwa ema-cog omunye nomunye, futhi njengoba i-rotor ijikeleza, amazinyo afakwe ema-cog omunye nomunye aya ekugcineni kokukhipha umoya, ukuze ivolumu evalwe ngamazinyo omunye inciphe kancane kancane, futhi ingcindezi ikhuphuke kancane kancane kuze kube yilapho ingcindezi edingekayo ifinyelelwa. Lapho ingcindezi ifinyelelwa, ama-cog axhumana ne-exhaust port ukuze athole i-exhaust.
Ngemva kokuba i-alveolar ifakwe ngamazinyo omphikisi asebenzisana nayo, kwakheka izikhala ezimbili ezihlukaniswe ngamazinyo. I-alveolar eduze kokuphela kokumunca yivolumu yokumunca, kanti eseduze kokuphela kokumunca yivolumu yegesi ecindezelwe. Ngokusebenza kwe-compressor, amazinyo e-rotor ephikisanayo afakwa ku-cogging aya ngasekugcineni kokukhipha, ukuze ivolumu yokumunca iqhubeke nokukhula futhi ivolumu yegesi ecindezelwe iqhubeke nokuncipha, ngaleyo ndlela kubonakale inqubo yokumunca nokucindezela ku-cogging ngayinye. Lapho ingcindezi yegesi yegesi ecindezelwe ku-cogging ifinyelela ingcindezi yokukhipha edingekayo, i-cogging ixhumana nje ne-vent bese inqubo yokukhipha iqala. Izinguquko kuvolumu yokumunca kanye nevolumu yokucindezela ehlukaniswe ku-cogging ngamazinyo e-rotor yomphikisi ziyaphindwa, ukuze i-compressor ikwazi ukuphefumula, icindezele futhi ikhiphe umoya njalo.
Isimiso sokusebenza kanye nesakhiwo se-screw compressor：
1. Inqubo yokumunca: Imbobo yokumunca ohlangothini lokungenisa lohlobo lwesikulufu kumele yakhelwe ukuze igumbi lokucindezela likwazi ukuhogela ngokuphelele. I-compressor yomoya yohlobo lwesikulufu ayinalo iqembu le-valve yokungenisa neyokukhipha. Ukungenisa kulungiswa kuphela ngokuvula nokuvala i-valve elawulayo. Lapho i-rotor ijikeleza, isikhala se-tooth groove yama-rotor amakhulu kanye nawasizayo sidluliselwa odongeni lokungena komoya, isikhala i-z* sikhulu, ngalesi sikhathi isikhala se-tooth groove ye-rotor sixhumana nomoya wamahhala we-air inlet, ngoba wonke umoya ose-tooth groove ukhishwa ngesikhathi sokukhipha umoya, kanti i-tooth groove isesimweni se-vacuum ekugcineni kwe-exhaust. Uma idluliselwa ekungeneni komoya, isikhala i-z* sikhulu. Ngalesi sikhathi, isikhala se-tooth groove ye-rotor sixhumana nomoya wamahhala we-air inlet, ngoba wonke umoya ose-tooth groove ukhishwa ngesikhathi sokukhipha umoya. Ekupheleni kwe-exhaust, i-tooth groove isesimweni se-vacuum. Uma idluliselwa endaweni yokungena emoyeni, umoya wangaphandle uyangena bese ugeleza ngokulingana ungene endaweni yokungena yamazinyo yama-rotor amakhulu kanye nalawo asekelayo. Ukugcinwa kwe-screw air compressor kukhumbuza ukuthi lapho umoya ugcwalisa yonke indawo yokungena yamazinyo, ubuso bokugcina bohlangothi lokungena komoya lwe-rotor buyasuswa endaweni yokungena yomoya ye-chassis, bese umoya ophakathi kwezindawo zokungena zamazinyo uvalwa.
2. Inqubo yokuvala nokudlulisa: Ekupheleni kokumunca kwama-rotor amakhulu nawasizayo, umsele wamazinyo wama-rotor amakhulu nawasizayo kanye ne-chassis kuyavalwa. Ngalesi sikhathi, umoya uvaliwe emseleni wamazinyo futhi awusaphumi, okungukuthi, [inqubo yokuvala]. Ama-rotor amabili ayaqhubeka nokujikeleza, futhi iziqongo zawo zamazinyo kanye nemisele yamazinyo kuyavumelana ekugcineni kokumunca, futhi ubuso be-anastomosis buhamba kancane kancane buye ekugcineni kokukhipha umoya.
3. Inqubo yokucindezelwa kanye nokujova uwoyela: Ngesikhathi senqubo yokudlulisa, indawo yokufaka i-mesh kancane kancane iya ekugcineni kokukhipha, okungukuthi, umsele wamazinyo phakathi kwendawo yokufaka i-mesh kanye ne-exhaust port iyancipha kancane kancane, futhi igesi emseleni wamazinyo icindezelwa kancane kancane futhi ingcindezi iyanda. Lena [inqubo yokucindezela]. Ngesikhathi esifanayo nokucindezela, uwoyela wokugcoba nawo ufafazwa ekamelweni lokucindezela futhi uxutshwe negesi yegumbi ngenxa yomehluko wokucindezela.
4. Inqubo yokukhipha ugesi: Lapho ubuso bokugcina be-meshing be-rotor yokulungisa i-screw air compressor budluliselwa ukuze buxhumane nokukhipha ugesi we-chassis, (ngalesi sikhathi ingcindezi yegesi ecindezelwe ingu-z*high) igesi ecindezelwe iqala ukukhishwa kuze kube yilapho ubuso bokufaka ugesi be-peak yezinyo kanye ne-tooth groove buyiswa ebusweni bokuphela kokukhipha ugesi. Ngalesi sikhathi, isikhala se-tooth groove phakathi kobuso bokufaka ugesi be-rotor ezimbili kanye ne-exhaust port ye-chassis singu-zero, okungukuthi, (inqubo yokukhipha ugesi) isiqediwe. Ngesikhathi esifanayo, ubude be-tooth groove phakathi kobuso bokufaka ugesi we-rotor kanye nokungena komoya kwe-chassis bufinyelela ku-z*long, futhi inqubo yokumunca iyaqhubeka.
Ama-screw air compressors ahlukaniswe kanje: uhlobo oluvulekile, uhlobo oluvalwe kancane, uhlobo oluvalwe ngokuphelele
1. I-screw compressor evalwe ngokuphelele: umzimba usebenzisa isakhiwo sensimbi esisezingeni eliphezulu, esinama-porosity aphansi esinokuguquguquka okuncane kokushisa; umzimba usebenzisa isakhiwo esinodonga oluphindwe kabili esine-exhaust passage, amandla aphezulu kanye nomphumela omuhle wokunciphisa umsindo; amandla angaphakathi nangaphandle omzimba alinganiselwe ngokuyisisekelo, futhi akukho bungozi bokuvuleka nokucindezela okuphezulu okuvalekile; igobolondo liyisakhiwo sensimbi esinamandla aphezulu, ukubukeka okuhle kanye nesisindo esilula. Isakhiwo esiqondile siyasetshenziswa, futhi i-compressor ithatha indawo encane, evumelana nokuhlelwa kwamakhanda amaningi e-chiller; i-bearing engezansi ifakwa ethangini likawoyela, futhi i-bearing igcotshwe kahle; amandla e-axial e-rotor ancishiswa ngo-50% uma kuqhathaniswa nohlobo oluvalekile noluvulekile (umphumela wokulinganisa we-motor shaft ohlangothini lwe-exhaust); akukho bungozi be-cantilever ye-motor evundlile, ukuthembeka okuphezulu; gwema umthelela we-screw rotor, i-spool valve, kanye nesisindo se-motor rotor ekuqondeni okufana, futhi uthuthukise ukuthembeka; inqubo enhle yokuhlanganisa. Umklamo oqondile wesikulufu ngaphandle kwepompo kawoyela wenza i-compressor ikwazi ukusebenza noma ukuma ngaphandle kokuntuleka kukawoyela. I-bearing engezansi ifakwa ethangini likawoyela iyonke, futhi i-bearing engenhla isebenzisa ingcindezi ehlukile yokuhlinzekwa kukawoyela; izidingo zengcindezi ehlukile yesistimu ziphansi. Uma kwenzeka isimo esiphuthumayo, umsebenzi wokuvikela ukugcotshwa kwama-bearing ugwema ukuntuleka kokugcotshwa kwama-oyela kwama-bearing, okusiza ekuvulekeni kweyunithi ngesikhathi sokuguquka. Okubi: Ukusetshenziswa kokupholisa ama-exhaust, imoto isendaweni yokukhipha ama-exhaust, okungabangela kalula ukuthi ikhoyili yemoto ishise; ngaphezu kwalokho, ukwehluleka akunakuphikwa ngesikhathi.
2. I-screw compressor evalwe kancane
Injini epholiswe ngesifutho, izinga lokushisa eliphansi lokusebenza kwenjini, impilo ende; i-compressor evulekile isebenzisa umoya ukupholisa injini, izinga lokushisa lokusebenza kwenjini liphezulu, okuthinta impilo yenjini, kanye nendawo yokusebenza yegumbi lekhompyutha ayilungile; ukusetshenziswa kwe-exhaust ukupholisa injini, izinga lokushisa lokusebenza kwenjini liphezulu kakhulu, impilo yenjini imfushane. Ngokuvamile, uwoyela wangaphandle mkhulu ngobukhulu, kodwa ukusebenza kahle kuphezulu kakhulu; uwoyela owakhelwe ngaphakathi uhlanganiswa ne-compressor, encane ngobukhulu, ngakho umphumela awulungile. Umphumela wesibili wokuhlukaniswa kwamafutha ungafinyelela ku-99.999%, okungaqinisekisa ukugcotshwa okuhle kwe-compressor ngaphansi kwezimo ezahlukahlukene zokusebenza. Kodwa-ke, i-plunger semi-enclosed screw compressor iqhutshwa yigiya ukwandisa isivinini, isivinini siphezulu (cishe i-12,000 rpm), ukuguguleka kukhulu, futhi ukuthembeka akukuhle.
I-compressor yesikulufa evulekile, ezintathu
Izinzuzo zamayunithi ohlobo oluvulekile yilezi: 1) I-compressor ihlukaniswe nemoto, ukuze i-compressor ibe nohlu olubanzi lwezicelo; 2) I-compressor efanayo ingasetshenziswa kuma-refrigerant ahlukene. Ngaphezu kwama-halogenated hydrocarbon refrigerant, i-ammonia ingasetshenziswa futhi njengesiqandisi ngokushintsha izinto zezingxenye ezithile; 3) Ngokusho kwama-refrigerant ahlukene nezimo zokusebenza, ama-motor anamakhono ahlukene angasetshenziswa. Izinkinga ezinkulu zamayunithi ohlobo oluvulekile yilezi: (1) I-shaft seal kulula ukuyivuza, okuyiyona nto egcinwa njalo ngabasebenzisi; (2) Imoto ehlonyisiwe ijikeleza ngesivinini esikhulu, umsindo wokugeleza komoya mkhulu, futhi umsindo we-compressor uqobo nawo mkhulu, okuthinta imvelo; (3) Kuyadingeka ukumisa isihlukanisi samafutha esihlukile, i-oil cooler nezinye izingxenye zesistimu yamafutha eziyinkimbinkimbi, iyunithi inkulu, ayilungele ukusetshenziswa nokuyinakekela.
