Chii chinonzi resistance yemagetsi yemuchina wekuputira mota?
Kudzivirira magetsi kwemuchina wemagetsi wemotokari ndicho chinhu chikuru chemagetsi muhurongwa hwemhepo inotonhodza motokari chinodzora kumhanya kwemuchina wemhepo (feni). Basa rayo guru nderekugadzirisa huwandu hwemhepo inobuda mumudziyo wemhepo (senge mazinga akaderera, epakati, epamusoro matatu kana anopfuura) nekutonga saizi yazvino.
Kudzora Kumhanya Kwechinyakare: Mumotokari zhinji dzinotonhodza mhepo nemaoko, kudzivirira kwemukati kwemota yemhepo kunoumbwa netambo dzakatevedzana dzekudzivirira dzakapatsanurwa kana kuti zvinodzivirira kubva muceramic-based alloy. Kana mushandisi akagadzirisa giya rekumhanya kwemhepo, dunhu rinochinja kuenda kunzira dzakasiyana dzekudzivirira, nokudaro richichinja magetsi ari kufamba nemumota yemhepo. Kudzivirira kukuru, simba remhepo diki, uye kumhanya kwemhepo kunoderedza. Kusiyana neizvi, pamagiya akakwira, simba remhepo rinopotsa rapfuura simba rekudzivirira, uye mota inoshanda nekumhanya kwakazara.
Kudzora Kumhanya kwePWM Yemazuva Ano: Dzimwe mota itsva (kunyanya idzo dzine ma air conditioning systems otomatiki) dzakashandisa tekinoroji ye pulse width modulation (PWM). Chigadziko che air conditioning control unit chinodzora avhareji yemagetsi kuburikidza nema electronic power transistors (akadai seMOSFETs) kuti chiwane stepless speed control. Zvisinei, izwi rekuti "wind motor resistance" richiri kushandiswa zvakanyanya kureva module yese ye wind speed control.
Zviratidzo zveChikanganiso Chakajairika
Kana simba remuchina wemhepo richikura kana kuti risingashande zvakanaka, chiratidzo chekukanganisa chingasave chakakonzerwa, asi matambudziko anotevera anogona kuitika:
Hapana mhepo mugiya repamusoro: Giya repasi kana repakati rinokundikana, uye vhoriyamu yemhepo haigone kuderedzwa.
Hapana mhinduro mugiya rakati: Semuenzaniso, "giya rechipiri" kana "giya rechitatu" hariburitse mhepo kana rakadzvanywa.
Hapana mhepo zvachose: Kudzivirira kwacho kwatyoka zvachose, uye mvura haigone kupfuura nepakati.
Kuchinja kamwe kamwe kwemhepo kana ruzha rwekurira: Kusabatana zvakanaka kwemukati kana oxidation yewaya yekudzivirira kunotungamira kune current isina kugadzikana.
Zvikonzero zvekukundikana uye kushaya simba
Kupisa kwakanyanya: Kupisa uku kunowanzoonekwa pakupisa kwakanyanya mumigero yemhepo yesystem yekutonhodza, uye majoini ewaya kana esimbi anowanzo kukwegura uye kupfupika.
Kuneta nekudedera: Kudedera kunoramba kuripo panguva yekushanda kwemotokari kunokonzera nzvimbo dzekubatanidza dzakasununguka kana dzakaputsika.
Kuora kwemvura: Munzvimbo dzine hunyoro dzekumaodzanyemba kana mushure mekusukwa, hunyoro hunopinda mukati, zvichikurumidzisa oxidation yezvikamu zvesimbi.
Zvinhu uye Dhizaini: Mamwe mamota ekare (akadai seAudi Q5 B8, Buick LaCrosse, Kia Sportage, nezvimwewo) ane dhizaini yepakutanga yekubvisa kupisa, uye mwero wekukundikana kwemota mumakore mashanu unowedzera zvakanyanya.
Mazano ekugadzirisa
Mamodule ekutanga kana anoenderana: Zvigadzirwa zvevamwe zvinogona kunge zvine simba kana resistance zvisingaenderane, zvichikonzera kukuvara kwechipiri kana kusabatana zvakanaka.
Kuisa kuri nyore: Mota zhinji dzine nzvimbo dzepakutanga dzemotokari dzakabatana zvakananga, dzisingade waya itsva kana mapurogiramu.
Tarisa kutevedzana: Kana paine kusagadzikana kwekumhanya kwemhepo, zvinokurudzirwa kutanga watarisa fuse (semuenzaniso, Volkswagen Passat SC39/SB29), wozoyera kukosha kwekudzivirira (nzvimbo yakajairika inenge iri pakati pe5–15 Ω), wozopedzisira watarisa mota.
Kusagona kushandisa injini yemhepo kudiki asi chinhu chikuru chinokanganisa nyaradzo mukati memotokari. Kukundikana kwayo kunowanzo fungidzirwa se "kusaita mhepo inotonhora" kana "kutadza kushanda kwemota," asi chaizvoizvo kunongova kutadza kudzora kumhanya kwemhepo. Kutsiva nekukurumidza kunogona kudzorera ruzivo rwekugadzirisa kumhanya kwemhepo.
Basa guru rekudzivirira mhepo inotonhodza nderekudzora kumhanya kwekutenderera kwefeni inotonhodza, nokudaro ichidzora saizi yenzvimbo inobuda mhepo. Musimboti wayo wekushanda uye hunhu hwayo ndehwekuti:
Basa Guru
Kudzora kumhanya kwemhepo: Nekuchinja kukosha kwekudzivirira kuti kuganhurira magetsi ari kuyerera nemota yemhepo inotonhodza mhepo, kuwana marongero akawanda ekumhanya kwemhepo (senge yakaderera, yepakati, yepamusoro, uye yepamusoro).
Kudzora tembiricha yekubatsira: Kunyangwe isingadzore tembiricha zvakananga, inokanganisa kusanganiswa kwemhepo inotonhora nemhepo inopisa mushure mekutumirwa, ichiita zvisina kunanga mukudzora tembiricha. Nheyo yekushanda
Mumasystem echinyakare emakanika, resistance yemota yemhepo inoumbwa nema resistor akawanda ane hunhu hwakasiyana. Kana vashandisi vakasarudza magiya akasiyana ekumhanya kwemhepo, vanenge vachichinja resistance vari mucircuit, nokudaro vachichinja voltage yemota nekumhanya kwayo.
Pagiya rinomhanya zvakanyanya (kana muma air conditioning systems otomatiki), ma resistors anowanzo pfuura, uye mota yacho yakabatana zvakananga nemagetsi, zvichiita kuti pave nemagetsi akanyanya uye kumhanya kwakanyanya.
Mota dzemazuva ano dzinonyanya kushandisa mamodule ekudzora kumhanya kwemagetsi (akadai sePWM-controlled MOSFETs), ayo anogadzirisa avhareji yemagetsi nekuchinja duty cycle yepulse width modulation kuti awane stepless speed control, nekushanda kwakanyanya uye kupisa kushoma.
Zviratidzo zvezvikanganiso uye nzira dzekudzivirira
Zvikanganiso zvinowanzoonekwa: Kupisa simba rekudzivirira, kunyunguduka kwefuse, zvichiita kuti feni isakwanise kugadzirisa kumhanya, kazhinji kacho ichisiya giya repamusoro chete kana kuti isingatenderere zvachose.
Dziviriro yakavakirwa mukati: Mazhinji mafeni anodzivirira anobatanidzwa nemafuse ekupisa. Kana feni yakamira kana kuti magetsi asina kujairika, fuse inonyunguduka kudzivirira kupisa zvakanyanya uye moto.
Nzvimbo yekuisa: Inowanzo gadziriswa mumhepo inotonhodza, uchishandisa mhepo inoshanduka yefeni kuti iparadze kupisa.
Kana kumhanya kwemhepo kusingagone kugadziriswa, giya repamusoro chete riripo, kana kuti feni isingashande zvachose, zvinogona kunge kuti resistor yefeni yakakuvara. Zvinokurudzirwa kuti nyanzvi ishandise multimeter kuiedza kana kuitsiva kudzivirira njodzi dzemasekete.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
