Nangona i-injini yomoya kunye ne-impeller ngamanye amaxesha zisetyenziswa ngokutshintshanayo kwiimeko zemihla ngemihla, kwizicelo zobugcisa kunye nezoshishino iintsingiselo kunye nokusetyenziswa kwazo zihluke ngokucacileyo. I-injini yomoya ikholisa ukubhekisa kwifeni yemoto okanye kwinqwelomoya ephucula ukusebenza kwe-injini ngokusebenzisa iigesi zokukhupha ukuvuthela umphunga we-fuel kwi-injini. I-impeller yenziwe nge-disc, i-wheel cover, i-blade kunye nezinye iindawo. I-fluid ijikeleza kunye ne-impeller ngesantya esiphezulu phantsi kwesenzo se-impeller blades. Irhasi ichaphazeleka ngamandla e-centrifugal yokujikeleza kunye nokuhamba okwandisiweyo kwi-impeller, evumela ukuba idlule kwi-impeller. Uxinzelelo emva kwe-impeller luyanda.
1. Inkcazo kunye neempawu ze-injini yomoya
I-iturbine ngumatshini wamandla ojikelezayo oguqula amandla omthombo osebenzayo oqukuqelayo ube ngumsebenzi womatshini. Lelinye lawona malungu aphambili eenjini zenqwelomoya, iiinjini zegesi kunye neeinjini zomoya. Iibhleyidi ze-iturbine zidla ngokwenziwa ngentsimbi okanye ngemathiriyeli ye-ceramic kwaye zisetyenziselwa ukuguqula amandla e-kinetic olwelo abe ngamandla omatshini. Uyilo kunye nomgaqo wokusebenza wee-injini ze-injini zichaza ukusetyenziswa kwazo kwiinkalo ezahlukeneyo zemizi-mveliso, ezifana neenqwelomoya, iimoto, ukwakha iinqanawa, oomatshini bobunjineli, njl.
I-turbine blades ngokuqhelekileyo iquka iindawo ezintathu eziphambili: icandelo lokungena, icandelo eliphakathi kunye necandelo lokuphuma. Iincakuba zecandelo lokungena zibanzi ukukhokelela ulwelo kumbindi weinjini yomoya, iincakuba zecandelo eliphakathi zibhityile ukuphucula ukusebenza kakuhle kweinjini yomoya, kwaye iincakuba zecandelo lokuphuma zisetyenziselwa ukutyhala ulwelo oluseleyo luphume kwiinjini yomoya. I-turbocharger inokunyusa kakhulu amandla kunye ne-torque ye-injini. Ngokuqhelekileyo, amandla kunye netorque ye-injini emva kokufaka i-turbocharger iya kwanda nge-20% ukuya kwi-30%. Nangona kunjalo, i-turbocharging ikwanezinto zayo ezingeloncedo, ezinje nge-turbo lag, ingxolo eyandisiweyo, kunye nemicimbi yokuphelisa ubushushu.
2. Inkcazo kunye neempawu ze-impeller
I-Impeller ibhekisa kwidiski yevili exhotyiswe ngeencakuba ezihambayo, eyinxalenye yerotor ye-impulse ye-injini yomoya. Isenokuthi ibhekiselele kwigama eliqhelekileyo lediski yevili kunye neeblade ezijikelezayo ezifakwe kuyo. Ii-impellers zihlelwa ngokwemilo yazo kunye neemeko zokuvula kunye nokuvala, ezifana ne-impellers evaliweyo, i-semi-open impellers kunye ne-impellers evulekile. Uyilo kunye nokukhethwa kwezinto ze-impeller kuxhomekeke kuhlobo lolwelo olufuna ukusingatha kunye nomsebenzi ofunekayo ukuwugqiba.
Umsebenzi ophambili we-impeller kukuguqula amandla omatshini we-prime mover kumandla oxinzelelo lwe-static kunye namandla oxinzelelo oluguquguqukayo lwamanzi asebenzayo. Uyilo lwe-impeller kufuneka lukwazi ukuphatha kunye nokuthutha ngokufanelekileyo ulwelo oluqulethe ukungcola okukhulu kwamasuntswana okanye imicu emide, kwaye kufuneka ibe nokusebenza kakuhle kokuchasana nokuvala kunye neempawu zokusebenza ezisebenzayo. Ukukhethwa kwezinto eziphathekayo ze-impeller nako kubaluleke kakhulu. Izinto ezifanelekileyo kufuneka zikhethwe ngokobume bomsebenzi osebenzayo, njengentsimbi etyhidiweyo, insimbi engenasici, i-bronze kunye ne-non-metallic materials.
3. Uthelekiso phakathi kwe-injini yomoya kunye ne-impeller
Nangona iiiturbines kunye nezinto ezihambisayo zombini zibandakanya ukuguqula amandla olwelo lwekinetic abe ngamandla oomatshini, banomahluko omkhulu kwimigaqo yabo yokusebenza, uyilo, kunye nokusetyenziswa. I-injini yomoya jikelele ithathwa njengesixhobo samandla kwimoto okanye kwi-injini yenqwelomoya eyandisa ukusebenza kakuhle komphunga wamafutha ngeegesi zokukhupha, ngaloo ndlela inyusa ukusebenza kwe-injini. I-impeller i-energizer eguqula amandla omatshini abe yi-kinetic energy yolwelo ngokujikeleza, ukwandisa uxinzelelo lwe-fluid, kwaye idlala indima kwizicelo ezahlukeneyo zemizi-mveliso, ezifana nokumpompa ulwelo oluqulethe amasuntswana aqinileyo.
Kwii turbines, iiblade zihlala zincinci ukunika indawo enkulu yeblade kwaye zivelise amandla anamandla. Kwi-impeller, iiblades zihlala zityebile ukuze zinikeze ukuchasana okungcono kunye nokwandiswa. Ukongeza, iiblade ze-injini zihlala ziyilelwe ukujikeleza kunye namandla aphuma ngokuthe ngqo, ngelixa ii-impeller blades zinokuma okanye zijikeleze, ngokuxhomekeke kwiimfuno zesicelo2.
4. Isiphelo
Ukushwankathela, kukho iiyantlukwano ezicacileyo kwinkcazo, iimpawu kunye nokusetyenziswa kweeinjini zomoya kunye ne-impellers. Ii-turbines zisetyenziselwa ukuphucula ukusebenza kweenjini zokutsha zangaphakathi, ngelixa ii-impellers zisetyenziselwa ukuthutha kunye nokucubungula ulwelo kwiintlobo ezininzi zezicelo zoshishino. Uyilo lwe-turbine lugxile kumandla angaphezulu kunye nokusebenza kakuhle kunokubonelela, ngelixa i-impeller igxininisa ukuthembeka kwayo kunye nokukwazi ukuphatha iintlobo ezahlukeneyo zamanzi.
