Ulwimi lwesiTshayina lubangela umdla kakhulu. Igama elifanayo linokuba nemiphumo eyahlukileyo xa lisetyenziswe kwiimeko ezahlukeneyo. Umzekelo, igama elithi "shui bao" lithetha ukungabi nankathalo nokulahla abanye. Isenokwandiswa ukuba ithethe ukuba isibini siyaxabana size sohlukane ngenxa yokungavisisani. Eli gama lisetyenziswa rhoqo kwiinjini.
Ukulahlwa kwengxowa yinkcazo yempazamo yeenjini zerotor yenxeba, ebhekiselele kwisiphumo soguqulo lweradial yangaphandle yesiphelo esijikajikayo serotor ngenxa yesantya esiphezulu. Ukuba siyazi into malunga neenjini ze-rotor yenxeba, sinokufumanisa ukuba kukho izithintelo kwisantya solu hlobo lweemoto. Ukususela kwinani leepali, kukho iimoto ezininzi ezineepali ezi-6 okanye ngaphezulu, oku kuthetha ukuba isantya sabo esilinganisiweyo sincinci; abanye abavelisi beemoto baya kwenza i-4-pali ye-rotor motors, kodwa inkqubo yokuvelisa inzima kakhulu, kwaye i-rotor winding kufuneka ihlolwe ukuthembeka kwe-overspeed.
Okwenyani ukuveliswa kunye nokuqinisekiswa kubonisa ukuba i-rotor eqinile inamandla okuthintela ukuba iphakheji ingaphoswa ngaphandle kwe-rotor ethambileyo; ukongezelela, ukulungiswa okufunekayo, ukubopha, ukuvanisha kunye nokunyangwa kwamanyathelo okuphelisa iziphelo zizinto ezibaluleke kakhulu. Ngokuqinisekileyo, ukuba isixhobo sokunciphisa isantya songezwa ngexesha lokusebenza kwemoto, le ngxaki iya kusonjululwa.

Isizathu esisisiseko sokuphosa iphakheji yimpembelelo ye-centrifugal
Into eyenza isindululo sesangqa, ngenxa ye-inertia yayo, isoloko inotyekelo lokubhabha ecaleni kwecala lesangqa. Xa amandla angaphandle adityanisiweyo athi shwaka ngokukhawuleza okanye angonelanga ukunika amandla asecentripetal afunekayo kwintshukumo yesetyhula, iya kuhamba ngokuthe ngcembe ukusuka kumbindi wesangqa. Le nto ibizwa ngokuba yi-centrifugal phenomenon.
Ngethuba lokusebenza kwe-motor, i-particle nganye ye-rotor part ishukuma kwi-circular motion ejikeleze umbindi we-motor shaft. Ngokobudlelwane phakathi kwesantya kunye namandla e-centrifugal kwintshukumo yesetyhula, isantya esikhulu, kokukhona amandla aphakathi.
Ngokuqhelekileyo kubonakala ebomini kumatshini wokuhlamba imigqomo yokuphelelwa ngamanzi emzimbeni, ukwenza i-cotton candy, njl. Izilawuli zesantya se-Centrifugal, abavavanyi be-centrifugal, i-centrifugal dryers, i-centrifugal precipitators, i-washing machine dehydration barrels, ukwenza i-cotton candy, oomatshini bokuhlela i-automatic, i-discus kunye ne-sando yokuphosa ukhuphiswano kukhuphiswano. ezemidlalo, njalo njalo zonke izicelo ezisebenzayo umgaqo centrifugal.
Yonke into ineengenelo kunye neengxaki zayo. Ngenxa yamandla e-centrifugal, ezinye iingozi zinokuthi zenzeke, zibangele ukwenzakala kubomi babantu. Kwiimoto eziqhuba kwiindlela ezithe tye, amandla aphakathi afunekayo ekujikeni abonelelwa kukungqubana okumileyo phakathi kwamavili kunye nomgangatho wendlela. Ukuba isantya siphezulu kakhulu xa ujika, i-centripetal force efunekayo F inkulu kuneyona friction i-static ephezulu, kwaye imoto iya kwenza i-centrifugal motion kwaye ibangele iingozi zendlela. Ngoko ke, izithuthi azivumelekanga ukuba zigqithise isantya esichaziweyo kwiigophe zendlela. Isantya esiphezulu esijikelezayo amavili okusila, i-flywheels, njl. ngokuqhelekileyo iqhekeza kwaye idubule ngesantya esiphezulu ngenxa yamandla ezinto kunye nokuqhekeka kwangaphakathi.

Yintoni amandla e-centrifugal?
Amandla e-Centrifugal yi-virtual force, imbonakaliso ye-inertia, ehambisa into ejikelezayo kude nendawo yayo yokujikeleza. Kwi-Newtonian mechanics, i-centrifugal force isetyenziselwe ukuvakalisa iikhonsensepthi ezimbini ezahlukeneyo: amandla angasebenziyo aqatshelwe kwisakhelo sereferensi esingeyo-inertial, kunye nebhalansi yamandla asecentripetal. Kwi-Lagrangian mechanics, amandla e-centrifugal ngamanye amaxesha asetyenziswa ukuchaza amandla aqhelekileyo phantsi kwenkqubo yolungelelwaniso ngokubanzi.
Kwimeko eqhelekileyo, amandla e-centrifugal ayingowokwenyani. Umsebenzi wayo kukuqinisekisa kuphela ukuba imithetho yentshukumo kaNewton isenokusetyenziswa kwisakhelo sereferensi esijikelezayo. Akukho mandla e-centrifugal kwisakhelo sereferensi e-inertial, kwaye amandla angasebenziyo afuneka kuphela kwisakhelo sereferensi esinga-inertial.
Yiba nomfanekiso wediski ejikeleza kumbindi wayo ngesantya se-engular ye-ω. Kwi-disk ibhloko yokhuni ye-mass m, exhunywe ngentambo, enye isiphelo sayo igxininiswe kumbindi wediski (kwakhona isikhungo sokujikeleza). Ubude bentambo r. Ibhloko yokhuni ijikeleza kunye nediski. Ukucinga ukuba akukho ngxabano, ibhloko yokhuni ijikeleza ngenxa yoxinzelelo lwentambo. Kumbukeli ojikelezayo kunye nediski, ibhloko yokhuni imile. Ngokomthetho kaNewton, amandla ombane kwibhloko yokhuni kufuneka abe ngu-zero. Nangona kunjalo, ibhloko yeplanga ixhomekeke kuphela kumandla omnye, ukunyanzeliswa kwentambo, ngoko ke i-net force ayikho zero. Ngaba oku kukwaphula umthetho kaNewton? Umthetho kaNewton usebenza kuphela kwi-inertial system, kodwa inkqubo yereferensi yombukeli ojikelezayo kunye nediski yinkqubo engekho inertial, ngoko umthetho kaNewton awubambeli apha. Ukuze umthetho kaNewton uhlale ubambe kwi-non-inertial system, i-inertial force, ebizwa ngokuba yi-centrifugal force, kufuneka ikhankanywe.
Ubungakanani bamandla e-centrifugal bulingana noxinzelelo olunikezwa yintambo, kodwa ulwalathiso luchasene. Emva kokuba kuqaliswe amandla e-centrifugal, ukusuka kumbono wombukeli ojikelezayo kunye nediski, ibhloko yeplanga ifakwe ngaxeshanye phantsi koxinzelelo lwentambo kunye namandla e-centrifugal, alinganayo ngobukhulu kwaye aphikisanayo kwicala, kunye nomnatha. amandla ngu-zero. Ngeli xesha, ibhloko yeplanga imile, kwaye umthetho kaNewton uyinyaniso.
