Uhlalutyo lomgaqo osebenzayo we-screw compressor yomoya

Injini engundoqo/inkqubo yeemoto:

Icompressor yomoya ejijwayo enye ikwabizwa ngokuba yi-worm air compressor. I-meshing pair ye-screw air compressor enye yenziwe nge-screw yentloko-6 kunye namavili eenkwenkwezi ezi-2 11-izinyo. I-worm meshes kunye nevili leenkwenkwezi ezimbini ngexesha elifanayo nangona amandla e-worm alungelelaniswa, ukufuduka kuphindwe kabini. Sihlala sithi i-screw compressor ngokubanzi ibhekisa kwicompressor ephindwe kabini.
Uhlobo lwe-Screw-type (okt., i-twin-screw) izicinezeli zineperi yerotha enamazinyo ajiyileyo adibanisayo ajikeleziswayo. I-rotor ene-convex tooth surface ibizwa ngokuba yi-positive rotor, kwaye i-rotor ene-concave tooth surface ibizwa ngokuba yi-rotor engalunganga. Ngokujikeleza kwe-rotor emzimbeni, umthamo osebenzayo ngenxa yokuhlaselwa kwamazinyo okanye ukuqhawula kunye nokutshintsha rhoqo, ngaloo ndlela utshintsha rhoqo umthamo phakathi kwebini ngalinye lamazinyo e-rotor, ukufezekisa injongo yokufunxa, ukunyanzeliswa kunye nokukhupha.
Umatshini ophambili licandelo eliphambili lomatshini wokujija, naluphi na uhlobo lomatshini wokujija umatshini wawo ophambili kunye nendlela yokusebenza ziyafana.

A. Ukuphefumla kuqhubeka

I-rotor ijikeleza, i-toothed ngokuqhubekayo ukusuka kwi-Yin Yang rotor ye-rotor yezinyo, izinyo phakathi kwevolumu ekhulayo ngokuthe ngcembe, kunye ne-orifice yokufunxa edibeneyo, igesi ngokufunxa i-orifice ibe yivolumu phakathi kwamazinyo, de umthamo ufikelele kwixabiso eliphezulu phakathi kwamazinyo, kunye nokuqhawula i-orifice yokuqhawula. , isenzo esidibeneyo ngezinyo kunye neegobolondo ezivaliweyo phakathi kwamazinyo, inkqubo yokufunxa iphelile. Kubalulekile ukuba uqaphele ukuba umthamo phakathi kwamazinyo e-Yang rotor kunye ne-rotor ye-Yin ayixhunyiwe omnye komnye.

B. Inkqubo yoxinzelelo

I-rotor iyaqhubeka nokujikeleza. Ngaphambi kokuba umthamo phakathi kwamazinyo e-Yin kunye ne-Yang rotors idibaniswe, igesi kumthamo phakathi kwamazinyo e-Yang rotor ixinzelelwe kuqala ngokungena kwamazinyo e-Yin rotor. Emva kwe-Angle ethile, umthamo phakathi kwe-Yin kunye ne-Yang rotor yamazinyo idibaniswe ukwenza i-v-shaped tooth volume pair (umthamo wokuqala). Ngokudityaniswa kwamazinyo amabini e-rotor, umthamo wesiseko utyhalelwa phambili ngokuthe ngcembe kwaye umthamo uyancitshiswa kancinci ukuze uqonde inkqubo yoxinzelelo lwegesi. Inkqubo yoxinzelelo igqityiwe de umthamo wento udityaniswe ne-exhaust orifice.

C. Inkqubo yokukhupha

Njengoko i-rotor ijikeleza, umthamo wento esisiseko uyancipha, kwaye igesi ecinezelweyo ithunyelwa kumbhobho wokukhupha, inkqubo iyaqhubeka de kube ivolumu ibe yincinci.
Ngokujikeleza okuqhubekayo kwe-rotor, ukufunxa okungentla, ukucinezelwa, umjikelo wenkqubo yokukhupha, umthamo wento nganye ngokulandelelanayo, yenza umjikelo wokusebenza we-screw refrigeration compressor.
Ukususela kuhlalutyo lwale nkqubo ingentla, kunokubonwa ukuba i-rotors ezimbini zijika kwicala lokutya omnye komnye, oko kukuthi, icala apho amazinyo e-convex kunye namazinyo e-concave adibana kunye, kwaye uxinzelelo lwegesi luyancipha kwaye lufake iifom. uxinzelelo oluphezulu, olubizwa ngokuba yindawo yoxinzelelo oluphezulu. Ngokuchasene noko, i-screw yajika ukuya kwicala elijongene nomnye, oko kukuthi, amazinyo e-convex kunye namazinyo e-concave omnye komnye ngaphandle kwecala, umthamo phakathi kwamazinyo ekwandeni koxinzelelo oluphantsi, owaziwa ngokuba yindawo yoxinzelelo oluphantsi. Imimandla emibini ihlukaniswe ngumgca woqhagamshelwano wezindlu kunye ne-rotor, kwaye i-axial plane yee-rotors ezimbini inokuqwalaselwa ngokufanelekileyo njenge-interface phakathi kweendawo eziphezulu kunye neendawo eziphantsi. Ukongeza, umjelo ojikelezayo owenziwe yimigca ye-meshing phakathi kwe-Yin kunye ne-Yang rotors ibangela ukuba igesi kumthamo wesiseko sesiseko ukuba ihambe ngokujikelezayo ukusuka ekupheleni kokufunxa ukuya kwisiphelo sokukhupha ngelixa ixinzelelwe.
Screw compressor njengecompressor ejikelezayo, kwisakhiwo sineempawu ze-centrifugal compressor, umgaqo wokusebenza ungowodidi lwecompressor efanelekileyo yokufuduka.

nezingeloncedo

·Ukuchaneka komatshini womphezulu wesithuba se-spiral rotor kuphezulu
·Umgca we-meshing phakathi kwee-rotors awukwazi ukufikelela ukutywinwa kakuhle kwe-interstage kwaye unqunyelwe ukuqina kwe-rotor. Okwangoku, i-screw compressor ayikwazi ukufikelela kuxinzelelo oluphezulu
·Isixhobo esiphakathi ngamaxesha athile sidlula kwindawo yokufunxa kunye ne-exhaust ngesantya esiphezulu, ngokuvuza kweentanda kunye nezinye izizathu, ukuze ingxolo yecompressor ibe nkulu, kuyafuneka ukuba kuthathwe amanyathelo okuphelisa ingxolo ukunciphisa ingxolo.

Ngenxa yezi mpawu zingentla, i-screw compressor isetyenziswa ngokubanzi kwezi meko zokusebenza zilandelayo

·Iindlela azikho phezulu kakhulu

semoto

Iqulethwe ngesakhelo somoya, isihlalo sokugqibela sokufunxa kunye nesitulo sokuphela kwe-exhaust, eyona nto iphambili yecompressor. Umzimba yinxalenye esembindini edibanisa inxalenye nganye, inika indawo echanekileyo yokuhlanganisa inxalenye nganye, iqinisekisa i-Yin kunye ne-Yang rotor meshing kwi-cylinder, iqhuba umsebenzi ngokuthembekileyo. Ubume bobuso bokugqibela ngu-∞, obufanelekileyo kwi-cylinder yangaphandle yee-rotors ezimbini ze-meshing, ukwenzela ukuba i-rotor ilayishwe ngokuchanekileyo emzimbeni. Udonga lwangaphakathi lomzimba lubonelelwa nge-radial suction orifice ehlangabezana neemfuno ze-rotor rotation Angle ukuqinisekisa ukuba i-rotor inokuqonda inkqubo yokufunxa kakuhle ngexesha lokujikeleza.
Isitulo sokufunxa kunye nesiphelo sokuphuma sisidibaniso sokutywina esibekwe ngaphambili nangasemva kwisiphelo somzimba we-injini. Ayenzi nje kuphela isiphelo sobuso betywina lomzimba we-injini, kodwa ibonelela ngendawo yokudibana ye-Yin kunye neYang rotor kunye ne-rotor exhasayo.

Rotor

Amacandelo aphambili oxinzelelo lwevolyum eguquguqukayo aqulunqwe yiYin kunye neYang rotors. Iprofayili ye-Rotor ifakwe ngokuchaneka okuphezulu izixhobo ezikhethekileyo zomatshini, izixhobo ezikhethekileyo zokusika, yenye yezona nxalenye eziphambili ze-compressor. Iprofayili ye-rotor idla ngokuba yi-unilateral asymmetrical cycloid -- iprofayili ye-arc. Yin kunye neYang rotor kwisakhiwo seendlela ezimbini ezilandelayo.
I-rotor efanelekileyo idibaniswe ne-motor njenge-rotor esebenzayo yokudlulisa i-torque kwaye iqhube i-rotor engalunganga (i-rotor eqhutywe) ukujikeleza ngobudlelwane be-meshing. I-rotors ye-Yin kunye ne-Yang ihambisa i-torque ngokuzibandakanya kunye nesixhobo sokuqhuba esiqhutywa yi-motor ngokusebenzisa iigiya zabo eziqhutywayo.

Ukunikela

Ukuthwala kukuxhasa i-rotor ye-Yin kunye ne-Yang, kunye nokuqinisekisa iindawo ezijikelezayo ze-rotor eziphezulu. Isiphelo se-motor ngokubanzi sithatha ukuthwala i-roller ukuxhasa. Okwesibini, xa i-rotor ijikeleza kwaye icinezela igesi, i-axial thrust iya kuveliswa. Ukuze unqobe lo mandla we-axial, enye isiphelo se-rotor ithatha i-oblique column bearing, engagqithisi kuphela i-axial force ye-rotor rotation, kodwa iphinda ithwale i-radial force.  
Uninzi lweecompressor ezijijwayo zithanjiswa ngenaliti yeoli. Ngokuxutywa kweoli yokuthambisa kunye nokusika kwi-compressor, kunye nokuhamba kwendawo yokuthambisa kunye nokutywinwa komatshini.
Iingenelo zezi zilandelayo
·Yehlisa ubushushu bokuphuma.
·Ukunciphisa ukuvuza okuphakathi okusebenzayo kunye nokuphucula isiphumo sokutywina
·Ukuphucula ukuthanjiswa kwamalungu, phucula ubomi benkonzo yamalungu
·Inefuthe lokufunxa kunye nokuthomalalisa kumaza esandi kwaye inokunciphisa ingxolo
·Susa ukungcola komatshini kwaye unciphise ukuguga
Nangona kunjalo, ngenxa yobuninzi be-oil injection, kuyimfuneko yokongeza inkqubo yeoli yokuthambisa kunye ne-oyile kunye ne-gas separator kwi-compressor outlet, eya kwandisa umthamo kunye nobunzima beyunithi. Ngelo xesha, le ndlela ayikwazi ukusetyenziswa kwimidiya engangcolisi. Ke ngoko, kukho iinxalenye zomatshini we-screw compressor wokuthambisa okungenawo ioli.
Ukusetyenziswa kwe-compressor engenawo ioli ineemfuno eziphezulu kwimvume yokuzibandakanya, ukuqina kunye nobunzima be-rotor kunye nomgangatho womatshini weyunithi yonke.
