Lokho Okushiwo Ngayo Ngempela?
Ukukhishwa kwesinye i-alternator kuvame ukuboniswa ngama-amperes, okungukuthi nje kuphela inani lamanje lelo unit elikwazi ukuhlinzekela kuzo zonke izinto ezixhunyiwe ohlelweni lwegesi. Lesi sibalo esibalulekile ngenxa yokuthi ama-alternators e-OEM ajwayele ukuhlonywa ukuphatha imithwalo eyengeziwe evela emishinini yokuvuselela kanye nokuthuthukiswa.
Uma lokho kwenzeka, futhi okukhiphayo kwakho okungenakukwazi ukuhlangabezana ngokugcwele nezidingo zesistimu yakho kagesi, ungathola noma yini kusuka ezinkanyeni ezibucayi ezinkingeni ezinzima zokushayela.
Ukushiya yedwa, le nkinga ekugcineni iyoholela ekwenzeni enye i-alternator.
Yiqiniso, kukhona umehluko phakathi kwesilinganiso se-alternator's "rating" nesilinganiso samanje esingasinikeza ngesivinini esingenzi lutho, yingakho kubalulekile ukuqonda ngokugcwele ukuthi ungafunda kanjani ukulinganisa okukhipha okunye uma unamandla amaningi Imishini esetshenzisiwe ngemuva
Ngenkathi ukulinganiswa kokukhipha kwe-alternator kukunika umbono walokho okuklanyelwe ukukhipha, indlela ewukuphela kokubona ukuthi i-alternator empeleni iyakwazi yini ukuyihlola. Ukuze wenze lokho, ungakwazi ukukala okukhipha okwenziwe kwe-alternator ngaphansi komthwalo olinganiselwe, okukuvumela ukuba uthole umqondo walokho okukwazi ukuveza izimo zomhlaba zangempela.
Ukulinganisa okuhlukile kwe-Alternator nezwe langempela
Igama elithi "alternator output" libhekisela kumqondo amabili ahlukene, kodwa ahlobene. Iyokuqala isilinganiso sokukhishwa kwe-alternator, okungukuthi inani lamanje ukuthi i-unit iyakwazi ukukhiqiza ngesivinini esithile sokujikeleza.
Isibonelo, i-alternator engu-100A ine-"valued" ye-100A, okusho ukuthi iyakwazi ukuhlinzeka nge-100A lapho i-alternator shaft ijikeleza ku-6,000 RPM.
Enye into eyenziwa yi-alternator engabhekisela kulokho okuyikho okwenziwa yiyo unit nganoma isiphi isikhathi, okuwumsebenzi wamandla omzimba we-alternator, isivinini sokujikeleza kwe-shaft yokufaka, kanye nezidingo zesikhashana uhlelo kagesi.
Ukuqonda ukulinganisa kwe-Alternator Ukulinganisa
Uma uzwa ukuthi i-alternator "ilinganiselwe ku-100A," ingasho izinto ezimbalwa ezihlukene kuye ngokuthi utholaphi ulwazi kusuka lapho. Isikhathi esisodwa ukuthi lokhu empeleni sinombono ocacile lapho umkhiqizi we-alternator noma u-rebuilder esebenzisa igama elithi "ukulinganisa" emandleni alo okuhloswe ngalo, okuchazwa yimibhalo yamazinga omhlaba njenge-ISO 8854 no-SAE J 56.
Kuzo zombili i-ISO 8854 ne-SAE J 56, ukuhlolwa kwe-alternator kanye namazinga okubeka amalebula kubonisa ukuthi "ukukhishwa okulinganiselwe" kwesinye isamba samanje ukuthi sikwazi ukukhiqiza ku-6,000 RPM. I-standard ngayinye ibuye ikhombise nezinye izinyathelo ezihamba phambili ukuthi enye i-alternator idinga ukuhlolwa futhi ichaza "ukukhishwa okungenzi lutho" nokukhishwa okuphezulu "ngaphezu" kokukhipha okulinganisiwe. "
Nakuba abakhiqizi be-alternator, abakhiqizi, nabathengi ngokuvamile babhekisela kokukhipha okulinganiselwe ezintweni zokuphromotha, kokubili i-ISO ne-SAE idinga ifomethi ye- "IL / IRA VTV," lapho i-IL iphansi, noma ingenzi lutho, i-IR yiyona lilinganiselwe ukukhishwa kwe-amperage, ne-VT yi-voltage yokuhlola.
Lokhu kubangela izilinganiso ezibukeka sengathi "50 / 120A 13.5V," ezivame ukuphrinta noma ukugxinwa ezindlini zomunye umuntu.
Ukuhumusha ukulinganisa kwe-alternator
Masithathe isibonelo kusigaba sangaphambilini bese sihlola:
50 / 120A 13.5V
Njengoba sazi ukuthi amazinga we-ISO nama-SAE amabili abiza ifomethi ye- "IL / IRA VTV" empeleni kulula kakhulu ukuhumusha lokhu kulinganisa.
Okokuqala, sizobheka i-IL, okuyilokho, okungu-50. Lokhu kusho ukuthi le-alternator iyakwazi ukubeka i-50A ngesivinini sokuhlola "esingaphansi," okungaba ngu-1,500 RPM noma "isivinini esingenalutho senjini, "Kuye ngokuthi yiliphi izinga osebenzelana nalo.
Inombolo elandelayo ingu-120, okuyi-"IR" noma okukhipha umphumela ekuvinjeni "okulinganisiwe" kokuhlola. Kulesi simo, le alternator ikwazi ukubeka i-RPA 120A @ 6,000.
Njengoba lokhu kungukuthi "kulinganiswe" isivinini sokuhlola, le nombolo ngokuvamile isetshenziselwa ukukhishwa kwesilinganiso se-alternator.
Inombolo yokugcina yi-13.5V, okuyi-"VT" noma i-voltage eyenziwa yi-alternator ngesikhathi sokuhlolwa. Njengoba ukukhiqizwa kwe-alternator kungashintsha kokubili kuya phezulu kusuka ku-13.5V ezimweni zangempela zomhlaba, kungumkhawulo wokukhipha okwamanje kuzohluka kusuka ezinombolweni ezingenalutho futhi ezilinganisiwe.
Ukuthengiswa kwe-Alternator nokufunwa
Ngalokhu konke engqondweni, kubalulekile futhi ukuqonda ukuthi ukukhishwa kwe-alternator kuhlanganiswe nezidingo zesistimu kagesi ngaphezu kwamakhono ayo akhona kanye nejubane lokuthi umshini walo wokufaka uphendukela nganoma yisiphi isikhathi.
Empeleni, ngenkathi ukukhishwa kwe-alternator enkulu kuncike ekuvinjeni kokujikeleza kwe-shaft yokufakwayo, ukukhishwa kwangempela kuxhomeke ekutheni ulayishe. Lokhu kusho ukuthi enye i- alternator ngeke ikhiqize kakhulu njengamanje ebizwa ngezimfuneko zesikhashana zomsisti kagesi.
Lokho kusho, ezweni langempela, ukuthi ngenkathi i-alternator engena ngaphansi kungabangela izinkinga ngokungahlangabezane nezidingo zesistimu yakho kagesi, elinye i-alternator elinamandla kakhulu limelela amandla amaningi okuchitha. Isibonelo, i- alternator ephezulu ekhishwayo ingase ikwazi ukubeka ngaphezulu kuka-300A, kodwa ngeke empeleni inikeze amperage ngaphezu kwesitoreji 80Ayunithi uma ngabe yonke uhlelo lombane luzama ukudweba.
Ingabe Udinga i-Alternator Alternator Alternator?
Ezimweni eziningi, ama-alternators ashintshwa ngenxa yokugqoka nokukhala okuvamile. Izingxenye zangaphakathi zivele ziphelelwe yisikhathi, ngakho-ke icala elingcono lokuthatha isinyathelo ukulibuyisela ngeyunithi entsha noma eyakhiwe ehambisana nezilinganiso ezifanayo zomkhiqizo.
Kunezimo lapho kunokwedlula ukwedlula ukwakhiwa kwe-alternator esikhundleni sokuthenga i-unit entsha noma eyakhiwe kabusha, kodwa leyo ingxoxo ehlukile.
Kunezimo lapho enye i-alternator ingashiswa ngenxa yezidingo ezidlulele isikhathi eside. Ngokuvamile lokhu akusebenzi ezitokisini ezinezinhlelo zomsindo wezimoto zamanye amazwe futhi azikho enye imishini eyengeziwe, kodwa ingaba ngokushesha njengoba uhlanganisa imishini elambile enezimboni.
Ezimweni lapho enye i-alternator ibonakala ishisa ngokushesha kunalindelekile, futhi imoto ine- amplifier ene-aftermarket enamandla , noma enye imishini efanayo, khona-ke ukushintshwa okulinganiselwe okulinganiselwe kungalungisa inkinga .
