Ii-screw air compressors zii-positive displacement compressors, ezifezekisa injongo yokucinezelwa kwegesi ngokunciphisa kancinci kancinci umthamo wokusebenza.
Umthamo osebenzayo we-screw air compressor wenziwe ngee-cogs ezimbini zee-rotors ezibekwe ngaxeshanye kwaye zidibene kunye kunye ne-chassis evumela ezi zibini zee-rotors. Xa umatshini usebenza, amazinyo ezi-rotors zimbini afakwa kwii-cogs zomnye nomnye, kwaye njengoko i-rotor ijikeleza, amazinyo afakwe kwii-cogs zomnye ahamba aye kwisiphelo se-exhaust, ukuze umthamo ovalelwe ngamazinyo omnye unciphe kancinci kancinci, kwaye uxinzelelo luyanda kancinci kancinci de kufikelelwe kuxinzelelo olufunekayo. Xa kufikelelwe kuxinzelelo, ii-cogs zinxibelelana ne-exhaust port ukuze zifumane i-exhaust.
Emva kokuba i-alveolar ifakwe ngamazinyo omchasi asebenzisana nayo, kwakheka izithuba ezibini ezahlulwe ngamazinyo. I-alveolar ekufutshane nesiphelo sokufunxa yivolumu yokufunxa, kwaye ekufutshane nesiphelo sokufunxa yivolumu yegesi ecinezelweyo. Ngokusebenza kwe-compressor, amazinyo e-rotor echaseneyo afakwe kwi-cogging aya kwisiphelo sokufunxa, ukuze umthamo wokufunxa uqhubeke wande kwaye umthamo wegesi ecinezelweyo uqhubeke uncipha, ngaloo ndlela kufezekiswa inkqubo yokufunxa kunye nokucinezela kwi-cogging nganye. Xa uxinzelelo lwegesi lwegesi ecinezelweyo kwi-cogging lufikelela kuxinzelelo olufunekayo lokukhupha, i-cogging inxibelelana nje nomoya kwaye inkqubo yokukhupha i-exhaust iqala. Utshintsho kwivolumu yokufunxa kunye nomthamo wokucinezela olwahlulwe kwi-cogging ngamazinyo e-rotor yomchasi luyaphindwa, ukuze i-compressor ikwazi ukuphefumla rhoqo, icinezele kwaye ikhuphe.
Umgaqo wokusebenza kunye nolwakhiwo lwe-screw compressor：
1. Inkqubo yokufunxa: Isango lokufunxa kwicala lokungenisa lohlobo lweskru kufuneka lenzelwe ukuba igumbi lokucinezela likwazi ukuphefumla ngokupheleleyo. I-compressor yomoya yohlobo lweskru ayinalo iqela levalvu yokungenisa kunye neyokukhupha umoya. Ukungenisa kulungiswa kuphela ngokuvula nokuvala ivalvu elawulayo. Xa i-rotor ijikeleza, indawo ye-tooth groove yee-rotors eziphambili kunye nezincedisi idluliselwa kwindawo yokuvula udonga lokungenisa umoya, indawo ye-z* inkulu, ngeli xesha indawo ye-tooth groove ye-rotor inxibelelana nomoya wasimahla wokungena komoya, kuba wonke umoya kwi-tooth groove ukhutshwa ngexesha lokukhupha umoya, kwaye i-tooth groove ikwimeko ye-vacuum ekupheleni kwe-exhaust. Xa idluliselwa kwi-air inlet, indawo ye-z* inkulu. Ngeli xesha, indawo ye-tooth groove ye-rotor inxibelelana nomoya wasimahla wokungena komoya, kuba wonke umoya kwi-tooth groove ukhutshwa ngexesha lokukhupha umoya. Ekupheleni kwe-exhaust, i-tooth groove ikwimeko ye-vacuum. Xa idluliselwa kwindawo yokungena emoyeni, umoya wangaphandle uyangena uze ugeleze ngqo kwi-groove yamazinyo yee-rotors eziphambili kunye nezincedisayo. Ukugcinwa kwe-screw air compressor kukhumbuza ukuba xa umoya ugcwalisa yonke indawo yamazinyo, ubuso bokugqibela becala lokungena komoya le-rotor buyajikwa busuke kwindawo yokungena yomoya ye-chassis, kwaye umoya ophakathi kweendawo zamazinyo uvaliwe.
2. Inkqubo yokutywina nokuhambisa: Ekupheleni kokutsalwa kweerotor eziphambili nezincedisayo, umngxuma wamazinyo weerotor eziphambili nezincedisayo kunye ne-chassis ziyavalwa. Ngeli xesha, umoya uvaliwe kumngxuma wamazinyo kwaye awusaphumi, oko kukuthi, [inkqubo yokutywina]. Ezi rotor zimbini ziyaqhubeka nokujikeleza, kwaye iincopho zamazinyo kunye nemingxunya yamazinyo ziyahambelana kwisiphelo sokutsalwa, kwaye umphezulu we-anastomosis uhamba kancinci ukuya kwisiphelo sokukhupha.
3. Inkqubo yokuxinwa kunye nokujova ioyile: Ngexesha lenkqubo yokuhambisa, umphezulu we-meshing uhamba kancinci kancinci uye kwisiphelo sokukhupha umoya, oko kukuthi, umngxuma wamazinyo phakathi komphezulu we-meshing kunye ne-exhaust port uyancipha kancinci kancinci, kwaye igesi ekwi-exhaust yamazinyo icinezelwa kancinci kancinci kwaye uxinzelelo luyanda. Le yi [nkqubo yokucinezelwa]. Ngexesha elifanayo nokucinezelwa, ioyile yokuthambisa ikwatshizwa kwigumbi lokucinezelwa kwaye ixutywe negesi yegumbi ngenxa yomahluko woxinzelelo.
4. Inkqubo yokukhupha umoya: Xa ubuso besiphelo se-meshing se-screw air compressor maintenance rotor budluliselwa ukuze buqhagamshelane ne-exhaust ye-chassis, (ngeli xesha uxinzelelo lwegesi ecinezelweyo luphezulu kakhulu) igesi ecinezelweyo iqala ukukhutshwa de kube umphezulu we-meshing wencochoyi yamazinyo kwaye umngxuma wamazinyo ufuduselwe kumphezulu we-exhaust. Ngeli xesha, indawo ye-tooth groove phakathi komphezulu we-meshing wee-rotors ezimbini kunye ne-exhaust port ye-chassis yi-zero, oko kukuthi, (inkqubo yokukhupha umoya) igqityiwe. Kwangaxeshanye, ubude be-tooth groove phakathi komphezulu we-meshing we-rotor kunye ne-air inlet ye-chassis ifikelela kwi-z*long, kwaye inkqubo yokufunxa iyaqhubeka.
Ii-screw air compressors zahlulwe zibe: uhlobo oluvulekileyo, uhlobo oluvaliweyo kancinci, uhlobo oluvaliweyo ngokupheleleyo
1. I-screw compressor evalekileyo ngokupheleleyo: umzimba usebenzisa isakhiwo sesinyithi esisemgangathweni ophezulu, esingenamibhobho iphantsi esinokuguquguquka okuncinci kobushushu; umzimba usebenzisa isakhiwo esinodonga oluphindwe kabini esinendlela yokukhupha umoya, amandla aphezulu kunye nesiphumo esihle sokunciphisa ingxolo; amandla angaphakathi nangaphandle omzimba alungelelaniswe ngokusisiseko, kwaye akukho mngcipheko woxinzelelo oluphezulu oluvulekileyo noluvalekileyo; iqokobhe lisakhiwo sentsimbi esinamandla aphezulu, inkangeleko entle kunye nobunzima obulula. Isakhiwo esithe nkqo siyasetyenziswa, kwaye i-compressor ithatha indawo encinci, elungele ukulungelelaniswa kweentloko ezininzi ze-chiller; i-bearing esezantsi intywiliselwa kwitanki yeoyile, kwaye i-bearing itshisiwe kakuhle; amandla e-axial e-rotor ancitshiswa ngama-50% xa kuthelekiswa nohlobo oluvalekileyo noluvulekileyo (isiphumo sokulinganisela se-motor shaft kwicala le-exhaust); akukho mngcipheko we-cantilever ye-motor ethe tye, ukuthembeka okuphezulu; phepha impembelelo ye-screw rotor, i-spool valve, kunye nobunzima be-motor rotor ekuchanekeni kokuhambelana, kwaye uphucule ukuthembeka; Inkqubo elungileyo yokuhlanganisa. Uyilo oluthe nkqo lweskrubhu ngaphandle kwepompo yeoyile lwenza ukuba icompressor isebenze okanye ime ngaphandle kokunqongophala kweoyile. Ibheyari esezantsi intywiliselwa kwitanki yeoyile iyonke, kwaye ibheyari engentla isebenzisa uxinzelelo oluhlukileyo lokubonelela ngeoyile; iimfuno zoxinzelelo oluhlukileyo lwenkqubo ziphantsi. Kwimeko yengxamiseko, umsebenzi wokukhusela ukuthambisa ibheyari uthintela ukungabikho kokuthambisa ioyile kwibheyari, okulungele ukuvulwa kweyunithi ngexesha lotshintsho. Iingxaki: Ukusetyenziswa kokupholisa i-exhaust, imoto ikwizibuko lokuphuma, okunokubangela ukuba i-coil yemoto itshise ngokulula; ukongeza, ukusilela akunakuthintelwa ngexesha.
2. Isikrufu sesikrufu esivalekileyo kancinci
Imoto epholisiweyo ngesitshizi, ubushushu obuphantsi bokusebenza kwemoto, ubomi obude; icompressor evulekileyo isebenzisa umoya ukupholisa imoto, ubushushu bokusebenza kwemoto buphezulu, nto leyo echaphazela ubomi bemoto, kwaye indawo yokusebenza yegumbi lekhompyutha ayilunganga; ukusetyenziswa kwe-exhaust ukupholisa imoto, ubushushu bokusebenza kwemoto buphezulu kakhulu, ubomi bemoto bufutshane. Ngokubanzi, ioyile yangaphandle inkulu ngobukhulu, kodwa ukusebenza kwayo kuphezulu kakhulu; ioyile eyakhelwe ngaphakathi idityaniswe necompressor, encinci ngobukhulu, ngoko ke isiphumo asilunganga. Isiphumo sokwahlulwa kweoyile yesibini sinokufikelela kwi-99.999%, nto leyo enokuqinisekisa ukuthambisa kakuhle kwecompressor phantsi kweemeko ezahlukeneyo zokusebenza. Nangona kunjalo, i-plunger semi-enclosed screw compressor iqhutywa yigiya ukwandisa isantya, isantya siphezulu (malunga ne-12,000 rpm), ukuguguleka kukhulu, kwaye ukuthembeka kwayo akukuhle.
Ezintathu, i-screw compressor evulekileyo
Iingenelo zeeyunithi zohlobo oluvulekileyo zezi: 1) I-compressor yahlulwe kwi-motor, ukuze i-compressor ibe noluhlu olubanzi lwezicelo; 2) I-compressor efanayo ingasetyenziswa kwiifriji ezahlukeneyo. Ukongeza kwiifriji ze-hydrocarbon ezine-halogenated, i-ammonia ingasetyenziswa njenge-refrigerant ngokutshintsha izinto zezinye iindawo; 3) Ngokweefriji ezahlukeneyo kunye neemeko zokusebenza, ii-motor zamandla ahlukeneyo zingasetyenziswa. Iingxaki eziphambili zeeyunithi zohlobo oluvulekileyo zezi: (1) I-shaft seal kulula ukuyivuza, nto leyo ekwayinto yokugcinwa rhoqo ngabasebenzisi; (2) I-motor exhotyisiweyo ijikeleza ngesantya esiphezulu, ingxolo yokuhamba komoya inkulu, kwaye ingxolo ye-compressor ngokwayo nayo inkulu, nto leyo echaphazela okusingqongileyo; (3) Kubalulekile ukumisela i-oil separator eyahlukileyo, i-oil cooler kunye nezinye izinto zenkqubo yeoyile ezintsonkothileyo, iyunithi inkulu, ayilungele ukusetyenziswa nokuyigcina.
