Muri moteri ya moteri harimo sensor ikurikirana ubushyuhe bwa coolant ikanagenzura imikorere yigikoresho.Soma ibyerekeranye nubushyuhe bwubushyuhe icyo aricyo, ubwoko bwubwoko, uko butunganijwe nakazi, uburyo bwo kubisimbuza - soma muriyi ngingo.
Ubushyuhe bwa PZD ni iki?
Ubushyuhe bwa PZD ni ikintu cya sisitemu yo kugenzura moteri ya moteri (icyuma gishyushya moteri, PZD), ikintu cyoroshye (gupima transducer) cyo gupima ubushyuhe bwa coolant.
Amakuru yabonetse ukoresheje sensor yubushyuhe yoherejwe murwego rwa elegitoronike igenzura gari ya moshi, kandi hashingiwe kubishyushya birahita bifungura, bihindura imikorere yabyo, guhagarika bisanzwe cyangwa guhagarika byihutirwa.Imikorere ya sensor biterwa nubwoko bwabo n’aho byashyizwe muri gari ya moshi.
Ubwoko, igishushanyo nihame ryimikorere yubushyuhe
Ibyuma byubushyuhe bigabanyijemo amatsinda ukurikije ihame ryimikorere ryashyizweho hashingiwe kubikorwa byabo, ubwoko bwibimenyetso bisohoka, igishushanyo mbonera.
Ukurikije ihame ryimikorere, sensor ni:
● Kurwanya - bishingiye kuri thermistor (thermistor), kwihanganira biterwa n'ubushyuhe.Iyo ubushyuhe buhindutse, ubukana bwa thermistor bwiyongera cyangwa bugabanuka, iyi mpinduka irandikwa kandi ikoreshwa mukumenya ubushyuhe buriho;
● Semiconductor - zishingiye ku bikoresho bya semiconductor (diode, transistor cyangwa ibindi), ibiranga inzibacyuho ya "pn" biterwa n'ubushyuhe.Iyo ubushyuhe buhindutse, ikigezweho-voltage iranga ihuriro rya "pn" (biterwa numuyoboro wa voltage) ihinduka, iyi mpinduka ikoreshwa mukumenya ubushyuhe bwubu.
Ibyuma bifata ibyuma birwanya ibintu nibyo byoroshye kandi bihendutse, ariko kubikorwa byayo birakenewe gukoresha umuzenguruko wihariye wo gupima, bisaba kalibrasi no guhinduka.Semiconductor sensor ituma bishoboka gukora microcircuits zumva ubushyuhe hamwe numuzunguruko wapimwe utanga ibimenyetso bya digitale mubisohoka.
Ukurikije ubwoko bwibisohoka, hari ubwoko bubiri bwubushakashatsi:
● Hamwe n'ibimenyetso bisa bisohoka;
● Hamwe nibisohoka bya signal.
Ibyuma byorohereza cyane nibyo bitanga ibimenyetso bya digitale - ntabwo byoroshye kugoreka no kwibeshya, biroroshye gutunganya hamwe numuyoboro wa kijyambere ugezweho, kandi ibimenyetso bya digitale byoroha guhuza sensor kugirango bapime ubushyuhe butandukanye kandi bitandukanye uburyo bwo gukora.
Ibyuma bya gari ya moshi bigezweho igice kinini cyubatswe hashingiwe kuri microcircuits zumva ubushyuhe hamwe nibimenyetso bya digitale.Intandaro ya sensor nkiyi ni silindrike ikozwe mubyuma birwanya ruswa (cyangwa hamwe na co-anti-ruswa), imbere hashyizwemo microcircuit yangiza ubushyuhe.Inyuma yurubanza hari umuhuza usanzwe wamashanyarazi cyangwa ibyuma bifata ibyuma bisohokana hamwe nu muhuza.Urubanza rufunze, rurinda chip amazi nizindi ngaruka mbi.Hanze y'urubanza, hari igikoni cyo gushyiramo reberi cyangwa silicone O-ring, kandi hashobora no gukoreshwa gaze yinyongera.Rukuruzi irwanya ibishushanyo bisa, ariko ifite amazu maremare maremare, amaherezo yayo hari ikintu cyoroshye.
Gahunda ya gari ya moshi yerekana ahantu hashyizwe ubushyuhe n'ubushyuhe bukabije
Hatitawe ku gishushanyo mbonera, ibyuma byubushyuhe bwa PZD bigabanijwemo ubwoko butatu ukurikije ibisabwa:
Rens Ibyuma bifata ubushyuhe - bikoreshwa mu gupima ubushyuhe bwamazi asohoka ava mumashanyarazi yerekeza kuri sisitemu yo gukonjesha amashanyarazi;
Sens Ubushyuhe bukabije - bukoreshwa mu gupima ubushyuhe bwamazi yinjira yinjira muri hoteri avuye muri sisitemu yo gukonjesha amashanyarazi;
● Kwisi yose - irashobora gukora nkubushyuhe bwubushyuhe bwamazi asohoka kandi yinjira.
Ubushyuhe bwubushyuhe bwamazi asohoka bushyirwa kuruhande rwumuyoboro wamazi usohora wa hoteri, ukoreshwa na sisitemu yo kugenzura kugirango uhindure umushyitsi no kuzimya mugihe ubushyuhe bwa moteri bugeze (mubisanzwe uri hagati ya 40 na 40 80 ° C, ukurikije gahunda yatoranijwe nuburyo bwo gukora gari ya moshi).Kubera ko iyi sensor ikoreshwa mugukurikirana no kugenzura ubushyuhe, byitwa gusa ubushyuhe bwubushyuhe.
Rukuruzi rushyushye rushyizwe kuruhande rwimbere ya preheater yamazi, ikoreshwa muguhita uzimya igikoresho mugihe colant yashushe.Niba, kubwimpamvu imwe cyangwa iyindi, ishami rishinzwe kugenzura ntirizimya ubushyuhe mugihe ubushyuhe burenze hejuru ya 80 ° C, noneho umuzenguruko urinda urakanguka, ukazimya ku gahato preheater, bikabuza moteri gushyuha.
Rukuruzi rusange rushobora gukora imirimo yibikoresho byombi, byashyizwe kumuyoboro usohoka cyangwa winjiza amazi, kandi bigashyirwaho ukurikije imirimo bashinzwe.
Muri preheater zigezweho, ibyuma bibiri bikoreshwa - ubushyuhe n'ubushyuhe bukabije.Ikimenyetso cyabo kigaburirwa inyongeramusaruro zijyanye nigice gishinzwe kugenzura gari ya moshi, mugihe ikimenyetso kiva mubyuma byubushyuhe (amazi asohoka) birashobora gukoreshwa kugirango berekane amakuru kumyerekano yerekana akanama gashinzwe kugenzura abagenzi / cab yimodoka, na ikimenyetso kiva mubushyuhe burashobora gukoreshwa kugirango umenyeshe ubushyuhe bwa moteri.
Guhitamo no gusimbuza ibyuma byerekana ubushyuhe
Ubushyuhe bugezweho bufite sisitemu yo kwisuzumisha imenyesha umushoferi imikorere mibi yubushyuhe bwikimenyetso hamwe nikimenyetso kumyerekano yububiko cyangwa kumurika LED.Mu bihe byose, niba hakekwa ko hari imikorere mibi, birakenewe kugenzura niba imiyoboro y'amashanyarazi yizewe hamwe na sensor - uburyo bwo kubikora byerekanwe mumabwiriza yo gukora no gusana gari ya moshi.Niba hagaragaye imikorere mibi, sensor yubushyuhe igomba gusimburwa, bitabaye ibyo ubushyuhe ntibushobora gukora mubisanzwe.
Kugirango usimburwe, birakenewe guhitamo sensor zumubare wurutonde nubwoko bwerekanwe mumabwiriza ya gari ya moshi.Uyu munsi, ababikora benshi batanga ibigereranyo byibikoresho bizwi cyane, byorohereza guhitamo kwabo.Ariko, mugihe uhisemo, ntushobora kwizera buhumyi umugurisha - ugomba kumenya neza ko sensor nshya ifite ubwoko bwihuza kandi ifite gasike mubikoresho.
Gusimbuza ubushyuhe hamwe nubushyuhe bukabije bikorwa hakurikijwe amabwiriza ya gari ya moshi, ariko hatitawe ku cyerekezo gishyushya, iki gikorwa kigomba gukorwa gusa kuri moteri yahagaritswe hamwe na terefone zikurwa muri bateri na nyuma yo gukuramo amazi mu gukonjesha Sisitemu.Mugihe ushyiraho sensor nshya, birakenewe kwitegereza polarite yo guhuza amashanyarazi, hanyuma nyuma yo kuzuza ibicurane, shyira sisitemu.
Hamwe noguhitamo neza no gusimbuza ubushyuhe, ubushyuhe bwa moteri buzakora neza kandi neza mubihe byose.
