Ukuhlaziywa kwesimiso sokusebenza sohlelo lwe-screw air compressor

Injini eyinhloko/isistimu yemoto:

I-screw air compressor eyodwa ibizwa nangokuthi i-worm air compressor. I-meshing pair ye-screw air compressor eyodwa yenziwe isikulufu esinamakhanda angu-6 namasondo enkanyezi angu-2 11-tooth. I-worm meshes enamasondo ezinkanyezi ezimbili ngesikhathi esisodwa nakuba amandla e-worm alinganisela, ukufuduka kuphindwe kabili. Ngokuvamile sithi i-screw compressor ngokuvamile ibhekisela ku-screw compressor ephindwe kabili.
I-screw-type (okungukuthi, ama-twin-screw) ama-compressor anepheya lama-rotor anamazinyo asongekile ahlangana ngokuzungeza okuphambene. I-rotor ene-convex tooth surface ibizwa ngokuthi i-rotor enhle, futhi i-rotor ene-concave tooth surface ibizwa ngokuthi i-rotor engalungile. Ngokujikeleza kwe-rotor emzimbeni, umthamo osebenzayo ngenxa yokuhlasela kwamazinyo noma ukuhlukanisa futhi ushintsha njalo, ngaleyo ndlela ngezikhathi ezithile ushintsha ivolumu phakathi kwepheya ngalinye lamazinyo e-rotor, ukufeza inhloso yokudonsa, ukucindezela nokukhipha.
Umshini oyinhloko uyingxenye eyinhloko yomshini wesikulufa, noma yiluphi uhlobo lomshini wesikulufa ukwakheka kwawo komshini oyinhloko nendlela yokusebenza kuyafana.

A. Ukuphefumula kuyaqhubeka

I-rotor ijikeleza, i-toothed ngokuqhubekayo isuka ku-Yin Yang rotor yezinyo, izinyo phakathi kwevolumu ekhulayo kancane kancane, futhi i-orifice yokumunca ixhunyiwe, igesi ngokumunca i-orifice ibe ivolumu phakathi kwamazinyo, kuze kube yilapho ivolumu ifinyelela inani eliphakeme phakathi kwamazinyo, nokukhipha i-orifice ukunqamula, isenzo esihlangene ngezinyo kanye namagobolondo ivolumu evaliwe phakathi kwamazinyo, inqubo yokumunca ingaphezu kwamazinyo. Kuyaqapheleka ukuthi ivolumu phakathi kwamazinyo we-Yang rotor kanye ne-Yin rotor ayixhunyiwe komunye nomunye.

B.Inqubo yokucindezelwa

I-rotor iyaqhubeka nokujikeleza. Ngaphambi kokuthi ivolumu phakathi kwamazinyo e-Yin ne-Yang rotor ixhunywe, igesi kuvolumu phakathi kwamazinyo e-Yang rotor icindezelwa kuqala ngokungena kwamazinyo e-Yin rotor. Ngemva kwe-engeli ethile, ivolumu phakathi kwamazinyo e-Yin ne-Yang rotor ixhunywa ukuze kwakheke ipheya yevolumu yezinyo elimise okwe-v (ivolumu eyisisekelo). Ngokukhiphana kwamazinyo amabili e-rotor, ivolumu yokuqala iqhubekela phambili kancane kancane futhi ivolumu iyancishiswa kancane kancane ukuze ibone inqubo yokucindezelwa kwegesi. Inqubo yokucindezela iqedwa kuze kube yilapho ivolumu ye-elementi ixhunywe ne-orifice yokukhipha.

C.Inqubo yokukhipha umoya

Njengoba i-rotor ijikeleza, umthamo wesici esiyisisekelo uyancipha, futhi igesi elicindezelwe lithunyelwa kumbhobho wokukhipha, inqubo iyaqhubeka kuze kube yilapho ivolumu incane kakhulu.
Ngokujikeleza okuqhubekayo kwe-rotor, ukumunca okungenhla, ukucindezelwa, umjikelezo wenqubo yokukhipha umoya, umthamo wento ngayinye usebenza ngokulandelana, uhlanganisa umjikelezo wokusebenza we-screw refrigeration compressor.
Kusukela ekuhlaziyweni kwenqubo engenhla, kungabonakala ukuthi ama-rotor amabili aphendukela ohlangothini lokudlela komunye nomunye, okungukuthi, ohlangothini lapho amazinyo e-convex namazinyo e-concave ahlangana khona, futhi ingcindezi yegesi iyancipha futhi yenza ukucindezela okuphezulu, okubizwa ngokuthi indawo yokucindezela okukhulu. Ngokuphambene nalokho, i-screw yaphendukela ohlangothini oluphambene nomunye nomunye, okungukuthi, amazinyo e-convex namazinyo ahlangene eceleni, ivolumu phakathi kwamazinyo ekwandiseni ingcindezi ephansi, eyaziwa ngokuthi indawo yengcindezi ephansi. Lezi zindawo ezimbili zihlukaniswe umugqa wokuxhumana wezindlu kanye ne-rotor, futhi indiza ye-axial ye-rotor emibili ingabhekwa cishe njenge-interface phakathi kwezindawo eziphakeme neziphansi zokucindezela. Ngaphezu kwalokho, isiteshi esivunguzayo esakhiwe imigqa yokuxhuma phakathi kwama-rotor e-Yin ne-Yang ibangela igesi kumthamo we-elementi eyisisekelo ukuthi ihambe ngokuzungeza isuka ekugcineni yokudonsa iye ekugcineni lapho ikhishwa khona ngenkathi icindezelwa.
I-screw compressor njenge-compressor ejikelezayo, esakhiweni inezici ze-compressor ye-centrifugal, isimiso sokusebenza siyingxenye yesigaba se-compressor enhle yokufuduka.

Okumbi

·Ukunemba komshini wendawo yendawo ye-spiral rotor kuphezulu
·Ulayini we-meshing ophakathi kwama-rotor awukwazi ukufinyelela ukuvala kahle kwe-interstage futhi unqunyelwe ukuqina kwe-rotor. Njengamanje, i-screw compressor ayikwazi ukufinyelela ukucindezela okuphezulu
·I-medium idlula ngezikhathi ezithile endaweni yokudonsa kanye ne-exhaust ngesivinini esikhulu, ngokuvuza kwemifantu nezinye izizathu, ukuze umsindo we-compressor ube mkhulu, kuyadingeka ukuthatha izinyathelo zokukhansela umsindo ukunciphisa umsindo.

Ngenxa yalezi zici ezingenhla, i-screw compressor ngokuvamile isetshenziswa kulezi zimo zokusebenza ezilandelayo

·Ithrafikhi ayiphezulu kakhulu ·Idinga isikhathi eside ukuze ihambe kahle ·Ingcindezi ephansi ye-exhaust

chassis

Yakhiwe ngohlaka lomoya, isihlalo sokuphela sokumunca kanye nesihlalo sokuphela kwe-exhaust, okuyingxenye eyinhloko ye-compressor. Umzimba uyingxenye emaphakathi exhuma ingxenye ngayinye, inikeza indawo efanele yokuhlangana engxenyeni ngayinye, iqinisekisa i-Yin ne-Yang rotor meshing kusilinda, iqhubekisela phambili umsebenzi ngokuthembekile. Ukuma kobuso bokuphela kungu-∞, okulungele isilinda sangaphandle sama-rotor amabili we-meshing, ukuze i-rotor ilayishwe ngokunembile emzimbeni. Udonga lwangaphakathi lomzimba luhlinzekwa nge-radial suction orifice ehlangabezana nezidingo ze-rotor rotation Angle ukuze kuqinisekiswe ukuthi i-rotor ingakwazi ukubona inqubo yokumunca kahle ngesikhathi sokuzungezisa.
Isihlalo sokudonsa kanye ne-exhaust iyisixhumi esivalayo esitholakala ngaphambili nangemuva kwengxenye yomzimba wenjini. Ayigcini nje ngokwenza uphawu lobuso bokugcina bomzimba wenjini, kodwa futhi ihlinzeka ngendawo yokuhlangana ye-Yin ne-Yang rotor kanye ne-rotor esekelayo.

Irotha

Izingxenye eziyinhloko zokucindezelwa kwevolumu eguquguqukayo zenziwe ngama-rotor ayi-Yin ne-Yang. Iphrofayili ye-Rotor yenziwe ngomshini ngamathuluzi omshini okhethekile wokunemba okuphezulu, amathuluzi okusika akhethekile, ingenye yezingxenye ezibalulekile ze-compressor. Iphrofayili ye-rotor ivamise ukuba yi-unilateral asymmetrical cycloid -- iphrofayili ye-arc. I-Yin ne-Yang rotor esakhiweni sezindlela ezimbili ezilandelayo.
I-rotor enhle ixhunywe ne-motor njenge-rotor esebenzayo yokudlulisa i-torque futhi ishayele i-rotor engalungile (i-rotor eqhutshwayo) ukuze ijikeleze ngobudlelwane be-meshing. I-Yin ne-Yang rotor idlulisa i-torque ngokuzihlanganisa negiya lokushayela elishayelwa injini ngamagiya awo ashayelwa.

Ukunikeza

I-Bearing iwukusekela i-Rotor ye-Yin ne-Yang, nokuqinisekisa izingxenye zokuzungezisa ngesivinini esiphezulu. Isiphetho se-motor ngokuvamile sithatha i-roller bear ukuze siyisekele. Okwesibili, lapho i-rotor ijikeleza futhi icindezela igesi, i-axial thrust izokhiqizwa. Ukuze unqobe la mandla we-axial, omunye umkhawulo we-rotor uthola ikholomu ye-oblique, engagcini nje ngokunqoba amandla e-axial we-rotor rotation, kodwa futhi ithwala amandla e-radial.  
Ama-screw compressor amaningi agcotshwa ngomjovo kawoyela. Ngokuxutshwa kwamafutha okugcoba nokusika ku-compressor, ngokugeleza kwe-medium yokugcoba nokuvala umshini.
Izinzuzo zimi kanje
·Yehlisa izinga lokushisa lokukhipha umoya.
·Yehlisa ukuvuza okuphakathi nendawo futhi uthuthukise umphumela wokuvala
·Thuthukisa ukugcotshwa kwezingxenye, uthuthukise impilo yezinsiza zezingxenye
·Inomphumela wokumunca kanye nokuthomalalisa kumaza omsindo futhi inganciphisa umsindo
Susa ukungcola kwemishini futhi unciphise ukuguga
Kodwa-ke, ngenxa yenani elikhulu lomjovo wamafutha, kuyadingeka ukwengeza uhlelo lwamafutha okugcoba kanye nesihlukanisi samafutha negesi endaweni yokukhipha i-compressor, okuzokwandisa ivolumu nobunzima beyunithi. Ngesikhathi esifanayo, le ndlela ayikwazi ukusetshenziselwa imidiya engangcolisi. Ngakho-ke, kukhona futhi izingxenye zomshini we-screw compressor ukugcoba okungenawo uwoyela.
Ukusetshenziswa kwe-compressor engenawo uwoyela kunezidingo eziphakeme ekuvumeni ukubandakanyeka, ukuqina kanye nesisindo se-rotor kanye nekhwalithi yomshini weyunithi yonke.
