I-Rheostat ne-stove resistor - iyini, imisebenzi kanye nesimiso sokusebenza
Okuqukethwe
Emaketangeni okuthengisa, ngokuvamile ungathola izingxenye ezingabizi zekhwalithi ephansi. Thatha izingxenye zikagesi kubathengisi abathembekile nabakhiqizi abanokwethenjelwa: ukuphishekela ukushibhile kungaphela engozini ku-wiring.
Akuwona wonke umshayeli oqonda ugesi wezimoto: kukholelwa ukuthi lokhu kuyilungelo lochwepheshe abancane. Kodwa kunezinto ezibalulekile abanikazi okufanele babe nokuqonda okuyisisekelo ngazo: isibonelo, kungani udinga i-rheostat yesitofu emotweni. Idivayisi ithinta ini, yiziphi izimpawu zokungasebenzi kahle kwayo, imisebenzi - funda kuqhubeke.
Iyini i-rheostat yesitofu emotweni
Imoto iwumshini oyinkimbinkimbi onamandla kagesi ozimele kanye nabathengi abaningi. Ugesi wemoto kufanele uhlale usesimweni sokusebenza, ngoba ukusebenza kwemoto, ukuphepha kanye nokuhamba kalula kwabagibeli kuncike kuyo.
Ama-ovens e-Rheostat ezimotweni
Ngaphansi kwe-hood yemoto kukhona isitshalo samandla esincane - i-generator. Kukhona ne-accumulator yamanje - ibhethri elishajekayo. Amandla anikezwa kubathengi bangaphandle ngezintambo, futhi into ngayinye kagesi emshinini inomshini wokulawula - i-rheostat (RS). Le ngxenye ithinta ukumelana namandla amanje wesekethe kagesi ngokushintsha inani lezigaba zedivayisi.
Kungani udinga
Imojula ye-heater yangaphakathi ezimotweni eziningi iqukethe ama-resistors amile. Kodwa enye inguqulo nayo ivamile, lapho ukumelana kushintsha cishe ngokuqhubekayo. Kukhona futhi ama-rheostats enza ukulungiswa okubushelelezi ngaphandle kokuphula inethiwekhi.
Emjikelezweni kagesi wemoto, i-rheostat yesitofu itholakala ngemuva kwebhokisi leglavu, phakathi kwe-drive (motor yesitofu sikagesi se-saloon) kanye nendlela exhunywe kuyo - i-heater. Umsebenzi wedivayisi ukudambisa ukukhuphuka kwamandla kagesi kanye nokunciphisa ukuqala kokugcwala okuthinta kabi kokubili idrayivu kanye nomthengi.
Ukuthi isebenza kanjani
I-rheostat yanoma yiluphi uhlobo isebenza ngokomthetho we-Ohm wesigaba sesekhethi. Idivayisi yesitofu semoto ibukeka njengomzimba we-ceramic oyi-cylindrical. Intambo yensimbi ene-cross section engashintshi ivamise ukulinyazwa engxenyeni. Ukuphenduka kwe-spiral kuhlukanisiwe komunye nomunye, njengoba i-non-conductive material isetshenziswa kubo bonke ubude.
Ukuthi isebenza kanjani
Ngenhla kwe-wire spiral, isilayidi sihamba eduze kwe-cylinder, okwenza ukumelana okungaphezulu noma okuncane kunethiwekhi kagesi. Lapho into ehambayo ihambela ohlangothini olulodwa, ubude besigaba sokuqhuba buyakhula. Ngalesi sikhathi, inani lokumelana ne-PC liyanda. Ngokuphambene, lapho isilayidi sihamba sibheke kolunye uhlangothi, ukumelana kwesigaba esifushane kwehla.
Iyini i-resistor yesitofu
Umgomo wokusebenza kwe-rheostat uyisihluthulelo sokuqonda ukuthi isitofu sesitofu sivula kanjani. Lokhu kwenzeka ngokwandisa noma ukunciphisa ukumelana kwesekethe. I-rheostat yesitofu se-saloon iqukethe izinto eziphikisayo - izakhi ezingenzi lutho ezimelana namandla amanje ageleza endaweni ephendukayo.
Inhloso yokusebenza ye-resistor yezimoto
I-resistor ifakiwe kunethiwekhi kagesi yezimoto phakathi komthombo kanye nomsebenzisi wamanje (ibhethri nesitofu). Ngakho-ke imisebenzi yengxenye:
- vikela isifunda ekukhuphukeni kwamandla;
- shintsha inani le-voltage kusuka kwenikeziwe kuya kwedingekayo;
- qinisekisa ukusebenza kahle kwama-electronics emoto.
Indima ye-resistor ekugcineni ukusebenza kwe-heater
Ugesi ukhiqizwa ebhethrini, lapho i-voltage iphezulu kakhulu ukuze abasebenzisi basebenze. Ngemuva kwesizukulwane, i-current iya ku-resistor: lapha i-voltage iguqulwa isuka kupharamitha enikeziwe kuya kweyifunayo. Ngemva kokudlula ku-resistor, i-voltage iba yinto efanelekile yokusebenza kwe-heater.
Izinhlobo resistors, izici zabo
Ama-resistors akhona kuzo zonke izinhlelo zemoto: ukupholisa nokufudumeza, ukuthungela nokukhanyisa. Ukusebenza kanye nemisebenzi yezingxenye ziyefana.
Izinhlobonhlobo zezakhi zihlukaniswe ngamaqembu amabili amakhulu:
- Layisha (njalo), udala ukumelana okuqhubekayo kokuphumayo.
- Okuguquguqukayo, lapho ukumelana kuguqulwa ngokuzenzela kube yilokho okudingwa idivayisi ethile yomthengi.
Izinhlobo resistors
I-subspecies yezinto eziguquguqukayo ingabizwa ngokuthi i-tuning resistors, ebuye ilungise ukumelana, kodwa hhayi nganoma yisiphi isikhathi, kodwa ngesikhathi sokuhlela kabusha yonke isekethe kagesi yemoto.
Ukukhethwa kokumelana nokumelana
Lapho into esebenza ngogesi iphuka emotweni, abashayeli bayayithwala ukuze iyokhandwa. Kodwa ngokuvamile umlandu wokuwohloka uyi-resistor, ukushintshwa kwayo okungadingi ulwazi lomuntu osebenza ngogesi.
Emaketangeni okuthengisa, ngokuvamile ungathola izingxenye ezingabizi zekhwalithi ephansi. Thatha izingxenye zikagesi kubathengisi abathembekile nabakhiqizi abanokwethenjelwa: ukuphishekela ukushibhile kungaphela engozini ku-wiring.
Izimbangela zokuhluleka kwama-resistors
Ngokuvamile, ukungasebenzi kahle kwengxenye kwenzeka ngenxa yesifunda esifushane kumjikelezo kagesi wemoto: kulo mzuzu, ukumelana nama-windings ku-motor kagesi ye-fan kuba ngaphansi kokubalulekile.Kodwa kunesinye isizathu. Uma izindwani ze-impeller yesitofu zilahlekelwe ukuthambisa noma zingcoliswe kakhulu, ingxenye ye-auto ijikeleza ngokuqinile. Ngakho-ke, i-resistor izohluleka ngokushesha.
Izimbangela zokuhluleka kwama-resistors
Ukuze ulondoloze impilo yokusebenza ye-spare part, ungagcini isitofu endaweni yokuqala isikhathi eside kakhulu, ngezikhathi ezithile ushintshe i-heater ngesivinini esiphezulu. Akunzima ukunquma ukuthi i-rheostat iyimbangela yokusebenza kabi kwe-heater cabin: xhuma i-multimeter kuzintambo zamandla zesici. Esinye isibonakaliso se-resistor engalungile: isitofu sisebenza kuphela ngokwedlulele, okwesine, isikhundla.
Ungathola idivayisi kwamanye amamodeli ezimoto nge-hood, lapho ingxenye itholakala ngaphansi komugqa wepulasitiki ("jabot"). Kwezinye izimoto, isici siyadilizwa futhi sishintshwe endaweni yabagibeli.
