Matsayi da Ƙa'idar Aiki na NTC Thermistor Sensors Temperature Sensors a cikin Tsarin Gudanar da Wuta na Mota

NTC (Negative Temperature Coefficient) na'urori masu auna zafin jiki suna taka muhimmiyar rawa a cikin tsarin sarrafa wutar lantarki, da farko don kula da zafin jiki da kuma tabbatar da amincin tsarin. A ƙasa akwai cikakken nazarin ayyukansu da ƙa'idodin aiki:

I. Ayyuka na NTC Thermistors

1. Kariyar zafi fiye da kima
   • Kula da Yanayin Mota:A cikin tsarin tuƙi na wutar lantarki (EPS), aikin motsa jiki na tsawon lokaci na iya haifar da zafi fiye da kima ko abubuwan muhalli. Na'urar firikwensin NTC yana lura da zafin mota a ainihin lokacin. Idan zafin jiki ya wuce madaidaicin madaidaicin, tsarin yana iyakance fitarwar wuta ko haifar da matakan kariya don hana lalacewar mota.
   • Kula da Zazzabi Ruwan Ruwa:A cikin tsarin tuƙi na wutar lantarki na lantarki (EHPS), haɓakar ruwan zafi na ruwa yana rage danko, ƙasƙantar da taimakon tuƙi. Na'urar firikwensin NTC yana tabbatar da tsayawar ruwa a cikin kewayon aiki, yana hana lalata hatimi ko yadudduka.
2. Inganta Ayyukan Tsari
   • Rarraba Rawan Zazzabi:A ƙananan zafin jiki, ƙara dankowar ruwa mai ƙarfi na iya rage taimakon tuƙi. Na'urar firikwensin NTC yana ba da bayanan zafin jiki, yana ba da damar tsarin don daidaita halayen taimako (misali, haɓaka motsi na yanzu ko daidaita buɗaɗɗen bawul na ruwa) don daidaitaccen tuƙi.
   • Sarrafa Mai ƙarfi:Bayanan zafin jiki na lokaci-lokaci yana haɓaka algorithms sarrafawa don haɓaka ƙarfin kuzari da saurin amsawa.
3. Binciken Laifi da Rage Tsaro
   • Yana gano kurakuran firikwensin (misali, buɗe/gajerun da'irori), yana haifar da lambobin kuskure, kuma yana kunna yanayin rashin aminci don kiyaye ainihin aikin tuƙi.

II. Ka'idodin Aiki na NTC Thermistor

1. Dangantakar Juriya-Zazzabi
   Juriya na thermistor NTC yana raguwa sosai tare da hauhawar zafin jiki, yana bin dabara:

                                                             RT=R0 ⋅eB(T1 -T01)

InaRT= juriya a yanayin zafiT,R0 = juriya na ƙididdigewa a yanayin zafiT0 (misali, 25°C), daB= abu akai-akai.

2. Canza sigina da Gudanarwa
   • Wutar Rarraba Wutar Lantarki: An haɗa NTC a cikin madaurin rarraba wutar lantarki tare da tsayayyen resistor. Juriya mai haifar da zafi yana canza canjin ƙarfin lantarki a kumburin mai raba.
   • Juyin AD da Lissafi: ECU tana jujjuya siginar wutar lantarki zuwa zafin jiki ta amfani da teburin dubawa ko ma'aunin Steinhart-Hart:

                                                             T1 =A+Bln(R)+C(lnR)) 3

• Kunna Kofa: ECU yana haifar da ayyukan kariya (misali, rage wutar lantarki) dangane da matakan da aka saita (misali, 120°C don injina, 80°C don ruwan ruwa).
2. Daidaitawar Muhalli
   • Marufi Mai ƙarfi: Yana amfani da matsanancin zafin jiki, mai jurewa mai, da kayan tabbatar da jijjiga (misali, resin epoxy ko bakin karfe) don matsananciyar mahallin mota.
   • Tace amo: Na'urorin sanyaya sigina sun haɗa da tacewa don kawar da tsangwama na lantarki.

     

III. Aikace-aikace na yau da kullun

1. EPS Motar Kula da Zazzabi
   • Saka a cikin stators mota don gano zafin iska kai tsaye, yana hana gazawar rufin.
2. Kula da Yanayin Zazzabi na Ruwan Ruwan Ruwa
   • An shigar da shi cikin hanyoyin zagayawa na ruwa don jagorantar daidaitawar bawul ɗin sarrafawa.
3. Kulawa da Rarraba Zafin ECU
   • Yana sa ido kan zafin jiki na ECU don hana lalata kayan lantarki.

IV. Kalubalen Fasaha da Magani

• Rarraba marasa kan layi:Madaidaicin madaidaicin daidaitawa ko jeri na yanki yana inganta daidaiton lissafin zafin jiki.
• Inganta Lokacin Amsa:Ƙananan nau'i-nau'i NTCs suna rage lokacin amsawar zafi (misali, <10 seconds).
• Tsawon Lokaci:NTCs-matakin mota (misali, ƙwararrun AEC-Q200) suna tabbatar da dogaro akan yanayin zafi mai faɗi (-40°C zuwa 150°C).

Takaitawa

Masu zafin jiki na NTC a cikin tsarin tuƙi na mota suna ba da damar sa ido kan zafin jiki na ainihin lokacin don kariyar zafi, haɓaka aiki, da gano kuskure. Babban ƙa'idarsu tana ba da damar sauye-sauyen juriya masu dogaro da zafin jiki, haɗe tare da ƙirar kewayawa da sarrafa algorithms, don tabbatar da aminci da ingantaccen aiki. Kamar yadda tuƙi mai cin gashin kansa ke tasowa, bayanan zafin jiki zai ƙara tallafawa kiyaye tsinkaya da haɓaka tsarin haɗin gwiwa.
