Mafuta mu antifreeze

Mafuta mu antifreeze Nthawi zambiri amawoneka chifukwa cha kusweka kwa silinda mutu gasket (yamphamvu mutu), komanso kuwonongeka kwa zinthu za dongosolo kuzirala, kuvala kwambiri kutentha exchanger gasket ndi zifukwa zina zimene tikambirana mwatsatanetsatane. Ngati mafuta amalowa mu antifreeze, ndiye kuti yankho la vutoli silingatheke, chifukwa izi zingayambitse mavuto aakulu pakugwira ntchito kwa magetsi a galimoto.

Zizindikiro za mafuta kulowa mu antifreeze

Pali zizindikiro zingapo zomwe zimamveka kuti mafuta amalowa muzoziziritsa kuzizira (antifreeze kapena antifreeze). Mosasamala kanthu za kuchuluka kwa mafuta omwe amalowa mu antifreeze, zizindikiro zomwe zili pansipa zidzasonyeza vuto lomwe liyenera kuthetsedwa mwamsanga pofuna kupewa kukonzanso kwakukulu ndi kodula kwa injini yoyaka mkati mwa galimoto.

Chifukwa chake, zizindikiro zosiya mafuta mu antifreeze ndi:

• Kusintha kwa mtundu ndi kusasinthasintha kwa zoziziritsa kukhosi. Normal ntchito antifreeze ndi bwino buluu, chikasu, wofiira kapena wobiriwira madzi. Kuchita mdima pazifukwa zachilengedwe kumatenga nthawi yayitali, ndipo nthawi zambiri kumafanana ndi kusintha kwachizolowezi kwa choziziritsa kukhosi. Chifukwa chake, ngati antifreeze idadetsedwa pasadakhale, ndipo koposa zonse, kugwirizana kwake kwakhala kokulirapo, ndi zonyansa zamafuta / mafuta, izi zikuwonetsa kuti mafuta alowa mu antifreeze.

• Pali filimu yamafuta pamwamba pa antifreeze mu thanki yowonjezera ya makina oziziritsira injini yamkati. Amawonekera ndi maso. Nthawi zambiri filimuyo imakhala ndi mdima wakuda ndipo imawonetsa kuwala kowala bwino mumitundu yosiyanasiyana (diffraction effect).
• Choziziriracho chimamva ngati chamafuta mukakhudza. Kuti mutsimikizire izi, mutha kutsitsa pang'ono antifreeze pa zala zanu ndikuzipaka pakati pa zala zanu. Antifreeze yoyera sidzakhala yamafuta, m'malo mwake, imatuluka mwachangu kuchokera pamwamba. Mafuta, ngati ali mbali ya antifreeze, amamveka bwino pakhungu.
• Kusintha kwa fungo la antifreeze. Nthawi zambiri, choziziriracho sichimanunkhiza konse kapena chimakhala ndi fungo lokoma. Ngati mafuta alowa mmenemo, madziwo amakhala ndi fungo loyaka moto losasangalatsa. Ndipo mafuta akachuluka m'menemo, m'pamenenso fungo lake silimasangalatsa komanso lodziwika bwino.
• Kuwotcha pafupipafupi kwa injini yoyaka moto mkati. Chifukwa chakuti mafuta amachepetsa ntchito ya antifreeze, womaliza sangathe kuziziritsa injini bwinobwino. Izi zimachepetsanso kuwira kwa choziziritsa. Chifukwa cha izi, ndizothekanso kuti antifreeze "idzaphwanyidwa" kuchokera pansi pa kapu ya radiator kapena kapu ya thanki yowonjezera ya dongosolo lozizira. Izi ndizowona makamaka pakugwira ntchito kwa injini zoyaka mkati munyengo yotentha (chilimwe). Nthawi zambiri, injini yoyaka mkati ikatenthedwa, ntchito yake yosagwirizana imawonedwa ("mawotchi").
• Madontho amafuta amawonekera pamakoma a thanki yokulirapo ya makina ozizirira.
• Pazipewa za thanki yowonjezera ya dongosolo lozizira ndi / kapena kapu ya radiator, ma depositi amafuta amatha kuchokera mkati, ndipo emulsion ya mafuta ndi antifreeze idzawonekera pansi pa kapu.
• Ndi kuwonjezeka kwa liwiro la injini yoyaka mkati mu thanki yowonjezera, mpweya wotuluka mumadzimadzi umawonekera. Izi zikuwonetsa kukhumudwa kwa dongosolo.

Zomwe zili pamwambazi zakonzedwa mu tebulo ili m'munsimu.

kotero, ngati wokonda galimoto akukumana osachepera chimodzi mwa zizindikiro pamwamba, ndiye m'pofunika kuti diagnostics zina, kuyang'ana mkhalidwe wa antifreeze, ndipo moyenerera, kuyamba kufufuza zifukwa zimene zinachititsa kuti zinthu.

Zomwe zimayambitsa mafuta kulowa mu antifreeze

Chifukwa chiyani mafuta amapita ku antifreeze? M'malo mwake, pali zifukwa zingapo zomwe kusweka uku kumachitika. Ndipo kuti timvetse chifukwa ndendende mafuta analowa antifreeze, m`pofunika kuchita diagnostics zina za boma la zinthu za injini kuyaka mkati.

Timatchula zomwe zimayambitsa kuyambira zodziwika kwambiri mpaka zosowa kwambiri:

• Kuwotchedwa kwa silinda mutu gasket. Zitha kukhala zonse zachilengedwe kuvala ndi kung'ambika, molakwika kumangitsa torque pakuyika (koyenera, kumangirizidwa ndi chowotcha cha torque), kusamveka bwino pakuyika, kukula kosankhidwa molakwika ndi / kapena zinthu za gasket, kapena ngati mota ikuwotcha.
• Kuwonongeka kwa ndege yamutu wa silinda. Mwachitsanzo, microcrack, sink, kapena kuwonongeka kwina kungachitike pakati pa thupi lake ndi gasket. Ndiponso, chifukwa cha izi chikhoza kubisika mu kuwonongeka kwamakina kwa mutu wa silinda (kapena injini yoyaka mkati yonse), kusokoneza mutu. ndizothekanso kuchitika kwa foci ya dzimbiri pamutu wa nyumba ya silinda.

• Valani gasket kapena kulephera kwa chotenthetsera chokha (dzina lina ndi lozizira mafuta). Chifukwa chake, vutoli ndiloyenera pamakina omwe ali ndi chipangizochi. The gasket akhoza kutayikira ku ukalamba kapena unsembe molakwika. Ponena za nyumba yopangira kutentha, imathanso kulephera (bowo laling'ono kapena ming'alu likuwonekera) chifukwa cha kuwonongeka kwamakina, ukalamba, dzimbiri. kawirikawiri, mng'alu amawonekera pa chitoliro, ndipo popeza kuthamanga kwa mafuta panthawiyi kudzakhala kwakukulu kuposa kuthamanga kwa antifreeze, mafuta odzola adzalowanso mu dongosolo lozizira.
• Gwirani mzere wa silinda. ndicho, kuchokera kunja. Chifukwa chake, chifukwa cha ntchito ya injini yoyaka mkati, mafuta omwe amalowa mu silinda mopanikizika ndi microcrack amatha kuyenda pang'onopang'ono kulowa muzoziziritsa.

Kuphatikiza pazifukwa zomwe zalembedwa zomwe zimakhala zamafuta ambiri amafuta ndi dizilo ICE, ma ICE ena ali ndi mawonekedwe awoawo, chifukwa chomwe mafuta amatha kutayira mu antifreeze ndi mosemphanitsa.

Imodzi mwa ma ICE awa ndi injini ya dizilo ya 1,7-lita yagalimoto ya Opel yomwe imatchedwa Y17DT yopangidwa ndi Isuzu. ndiye, mu injini zoyaka zamkati izi, mphuno zili pansi pa chivundikiro chamutu cha silinda ndipo zimayikidwa mu magalasi, mbali yakunja yomwe imatsukidwa ndi choziziritsira. Komabe, kusindikizidwa kwa magalasi kumaperekedwa ndi mphete zopangidwa ndi zinthu zotanuka zomwe zimauma ndi kusweka pakapita nthawi. Chifukwa chake, chifukwa cha izi, kuchuluka kwa kusindikiza kumatsika, chifukwa chake pali kuthekera kuti mafuta ndi antifreeze zimasakanikirana.

M'ma ICE omwewo, milandu imalembedwa nthawi zina pamene, chifukwa cha kuwonongeka kwa magalasi, mabowo ang'onoang'ono kapena ma microcracks adawonekera m'makoma awo. Izi zimabweretsa zotsatira zofananira za kusanganikirana kwamadzi amadzimadzi.

Zotsatira za mafuta kulowa mu antifreeze

Ambiri, makamaka oyamba kumene, oyendetsa galimoto ali ndi chidwi ndi funso ngati n'zotheka kuyendetsa pamene mafuta alowa mu antifreeze. Pankhaniyi, zonse zimatengera kuchuluka kwa mafuta omwe adalowa mu choziziritsa. Munthawi yabwino, ngakhale mafuta atayikira pang'ono mu antifreeze, muyenera kupita kugalimoto kapena garaja, komwe mungathe kudzikonza nokha kapena kutembenukira kwa amisiri kuti akuthandizeni. Komabe, ngati kuchuluka kwa mafuta mu ozizira ndi pang'ono, ndiye mtunda waufupi pa galimoto akhoza kuyendetsedwa.

ziyenera kumveka kuti mafuta samangochepetsa magwiridwe antchito a antifreeze (zomwe zimapangitsa kuchepa kwa kuzizira kwa injini yoyaka mkati), komanso kumawononga dongosolo lonse lozizira. komanso nthawi zambiri pakachitika ngozi zoterezi, osati mafuta okha omwe amalowa m'malo ozizira, koma mosiyana - antifreeze amalowa m'mafuta. Ndipo izi zikhoza kale kubweretsa mavuto aakulu pa ntchito ya injini kuyaka mkati. Choncho, pamene vuto lotchulidwalo lidziwika, ntchito yokonzanso iyenera kuchitidwa mwamsanga, chifukwa kuchedwa kwawo kumakhala ndi zochitika zowonongeka kwambiri ndipo, motero, kukonzanso kwamtengo wapatali. Izi ndizowona makamaka pakugwira ntchito kwagalimoto nyengo yotentha (chilimwe), pomwe kuzizira kwa injini yoyaka moto kumakhala kofunikira pagawo lamagetsi!

Chifukwa cha ntchito yozizira, yomwe ili ndi mafuta, mavuto otsatirawa ndi ICE agalimoto amatha kuchitika:

• Kutentha kwapang'onopang'ono kwa injini, makamaka poyendetsa galimoto panthawi yotentha komanso / kapena kuyendetsa injini yoyaka mkati mothamanga kwambiri (katundu wapamwamba).
• Kutsekedwa kwa zinthu za dongosolo lozizira (hoses, mapaipi, ma radiator) ndi mafuta, zomwe zimachepetsa mphamvu ya ntchito yawo mpaka pamlingo wovuta.
• Kuwonongeka kwa zinthu za dongosolo lozizira, zomwe zimapangidwa ndi mphira wosagonjetsedwa ndi mafuta ndi pulasitiki.
• Kuchepetsa gwero osati makina oziziritsa a injini yamkati, komanso injini yonse yonse, popeza ndi njira yoziziritsa yolakwika, imayamba kugwira ntchito kuti ivale kapena moyandikana ndi izi.
• Kukachitika kuti osati mafuta okha amalowa mu antifreeze, koma mosemphanitsa (antifreeze amalowa mumafuta), izi zimabweretsa kuchepa kwa mphamvu yamafuta amkati mwa injini yoyaka moto, chitetezo chawo ku mavalidwe ndi kutenthedwa. Mwachibadwa, izi zimakhudzanso ntchito ya injini ndi nthawi ya ntchito yake yachibadwa. Pazovuta kwambiri, injini yoyaka mkati imatha kulephera pang'ono kapena kulephera kwathunthu.

kotero, ndi bwino kuyamba ntchito yokonza mwamsanga kuti kuchepetsa zotsatira zoipa za mafuta odzola madzimadzi osati pa dongosolo kuzirala, komanso kupewa zotsatira zoipa pa injini kuyaka mkati mwa galimoto lonse.

Zoyenera kuchita ngati mafuta alowa mu antifreeze

Kuchita kwa kukonzanso kwina kumadalira chifukwa chomwe mafuta adawonekera mu thanki yoletsa kuzizira komanso munjira yonse yozizira.

• Kuwonongeka kwa cylinder head gasket ndiye vuto lofala kwambiri komanso lotha kuthetsedwa mosavuta ngati pali mafuta mu antifreeze. Pali njira imodzi yokha - kuchotsa gasket ndi yatsopano. Mutha kuchita izi nokha, kapena kulumikizana ndi ambuye kuntchito yamagalimoto kuti akuthandizeni. Ndikofunika panthawi imodzimodzi kusankha gasket ya mawonekedwe olondola komanso ndi miyeso yoyenera ya geometric. Ndipo muyenera kumangitsa mabawuti okwera, choyamba, motsatana (chithunzichi chikuwonetsedwa muzolemba zamagalimoto zamagalimoto), ndipo kachiwiri, kugwiritsa ntchito wrench ya torque kuti musunge ma torque olimbikitsa.
• Ngati mutu wa silinda (ndege yake yapansi) yawonongeka, ndiye kuti zosankha ziwiri ndizotheka. Yoyamba (yogwira ntchito kwambiri) ndikuyiyika pamakina oyenera. Nthawi zina, ming'alu imatha kupangidwa ndi utomoni wotentha kwambiri wa epoxy, wonyezimira, ndi kutsukidwa pamwamba ndi gudumu lopera (pamakina). Njira yachiwiri ndikusinthiratu mutu wa silinda ndi watsopano.
• Ngati pali microcrack pa liner ya silinda, ndiye kuti iyi ndi nkhani yovuta. Chifukwa chake, kuti muchepetse kuwonongeka uku, muyenera kufunafuna thandizo kuchokera kugalimoto yamagalimoto, komwe kuli makina oyenerera, omwe mungayesere kubwezeretsa chipika cha silinda kuti chigwire ntchito. ndiye, chipikacho ndi wotopa ndipo manja atsopano amaikidwa. Komabe, nthawi zambiri chipikacho chimasinthidwa kwathunthu.
• Ngati pali mavuto ndi chosinthira kutentha kapena gasket yake, ndiye kuti muyenera kuyichotsa. Ngati vuto lili mu gasket, ndiye muyenera m'malo. Kuzizira kwamafuta komweko kumadetsa nkhawa - mutha kuyesa kuyigulitsa kapena kuyisintha ndi ina. Chotenthetsera chokonzedwanso chiyenera kutsukidwa ndi madzi osungunuka kapena njira zapadera musanayike. Komabe, nthawi zambiri, kukonzanso kutentha kwa kutentha sikungatheke chifukwa cha kuchepa kwazing'ono komanso zovuta za mapangidwe a chipangizocho. Chifukwa chake, imasinthidwa ndi yatsopano. Chotenthetsera chotenthetsera chikhoza kuyang'aniridwa pogwiritsa ntchito mpweya wa compressor. Kuti tichite izi, imodzi mwa mabowo (cholowera kapena chotulukira) chaphwanyidwa, ndipo mzere wa mpweya wochokera ku compressor umalumikizidwa ndi chachiwiri. Pambuyo pake, chotenthetsera kutentha chimayikidwa mu thanki ndi kutentha (zofunika !!!, kutentha mpaka madigiri +90 Celsius) madzi. Pazifukwa zotere, aluminiyumu yomwe chowotcha chotenthetsera chimapangidwira chimakula, ndipo ming'alu ya mpweya idzatuluka mumng'alu (ngati ilipo).

Pamene chifukwa cha kuwonongeka ndi kumveka bwino ndi kuthetsedwa, musaiwale kuti m`pofunika m`malo antifreeze, komanso kutenthetsa dongosolo yozizira. Iyenera kuchitidwa molingana ndi algorithm yokhazikika komanso kugwiritsa ntchito njira zapadera kapena zotsogola. Zikachitika kuti kusinthana kwamadzimadzi kwachitika, ndipo mafuta oletsa kuzizira alowanso, ndiye kuti ndikofunikira kusintha mafutawo ndikuyeretsa koyambirira kwa injini yamafuta amkati.

Momwe mungatulutsire dongosolo lozizirira kuchokera ku emulsion

Kutsuka makina oziziritsa mafuta atalowa ndi muyeso wovomerezeka, ndipo ngati munyalanyaza kutsuka emulsion, koma kungodzaza antifreeze yatsopano, izi zidzakhudza kwambiri mizere ya utumiki ndi ntchito yake.

Musanayambe kutenthetsa, antifreeze yakale yowonongeka iyenera kuchotsedwa m'dongosolo. M'malo mwake, mutha kugwiritsa ntchito zida zapadera zafakitale pakuwotcha makina oziziritsa kapena otchedwa anthu. Pamapeto pake, ndi bwino kugwiritsa ntchito citric acid kapena whey. Yankho lamadzi lochokera pazinthu izi limatsanuliridwa mu dongosolo lozizirira ndikukwera ma kilomita angapo. Maphikidwe ogwiritsira ntchito amaperekedwa m'nkhani yakuti "Momwe mungatsitsire makina ozizira". Pambuyo pa kutenthetsa, antifreeze yatsopano iyenera kutsanuliridwa mu makina ozizira.

Pomaliza

Ndikotheka kugwiritsa ntchito galimoto yokhala ndi mafuta munjira yozizirira pokhapokha pazovuta kwambiri, mwachitsanzo, kuti mufike kugalimoto yamagalimoto. Ntchito yokonza iyenera kuchitidwa mwamsanga ndi chizindikiritso cha chifukwa ndi kuthetsa kwake. Kugwiritsira ntchito galimoto yomwe imasakaniza mafuta a injini ndi ozizira m'kupita kwanthawi imakhala ndi zovuta komanso zodula kwambiri. Ndiye ngati muwona mafuta ali mu antifreeze, imbani alamu ndipo konzekerani mtengo wake.
