Zifukwa za kuwira kwa antifreeze mu thanki yowonjezera

Normal ntchito ya injini kuyaka mkati n'zotheka kokha ngati mosalekeza utakhazikika. Zimachitika chifukwa cha kukakamizidwa kwa antifreeze kudzera munjira munyumba ya injini. Komabe, si zachilendo kuti kutentha kwa chozizirirapo chifike powira. Kunyalanyaza izi kungayambitse zotulukapo zowopsa komanso kukonza kodula. Choncho, mwini galimoto aliyense ayenera kudziwa bwino ndondomeko yowira antifreeze.

Chifukwa chiyani antifreeze amawotcha

Pali zifukwa zambiri zowiritsira zoziziritsa kukhosi (zozizira) mu thanki yowonjezera, zomwe zazikulu ndi izi:

• mlingo wochepa wa antifreeze mu thanki;
• kuwonongeka kwa thermostat;
• radiator yotsekedwa;
• kuwonongeka kwa fan fan;
• otsika khalidwe ozizira.

Muzochitika zonsezi, chozizirirapo sichikhala ndi nthawi yozizirira. Kutentha kwake kumawonjezeka pang'onopang'ono ndipo ikafika pa 120^оZimayamba kuwira.

Kuphika kwa antifreeze mu thanki yowonjezera kumayendera limodzi ndi nthunzi yoyera

Antifreeze imachokera ku ethylene glycol - mankhwala opangidwa kuchokera ku gulu la mowa. Zimalepheretsa kuti choziziritsa kuziziritsa chisazizira kwambiri. Ikawira, ethylene glycol imayamba kusungunuka. Mpweya wake ndi wapoizoni komanso wowopsa ku dongosolo lamanjenje laumunthu.

Kutsika kwa antifreeze mu thanki

Mukamawira, choyamba, yang'anani mlingo wa antifreeze mu thanki. Izi zichitike kokha pamene choziziriracho chazirala. Ngati kusowa kwamadzimadzi kumadziwika, njira zotsatirazi ziyenera kuchitidwa, malingana ndi momwe zinthu zilili.

1. Ngati ozizira sanatsanulidwe kwa nthawi yayitali, muyenera kuwonjezera antifreeze pamlingo wofunikira ndikupitiliza kuyendetsa.
   

   Ngati mulibe antifreeze wokwanira mu thanki yowonjezera, iyenera kuwonjezeredwa.

2. Ngati choziziritsa chatsanulidwa posachedwapa, ndipo mulingo wake mu thanki watsikira kale pamlingo wochepa kwambiri, choyamba muyenera kuyang'ana kukhulupirika kwa thanki yowonjezera. Kenako yang'anani mapaipi onse, mapaipi ndi zolumikizira zotsekera kuti zitsimikizire kutayikira kwa antifreeze. Ngati kutayikira kwapezeka, koma n'kosatheka kuthetsa vutoli, muyenera kupita kuntchito yamagalimoto pagalimoto yokoka.

Imodzi yolakwika imodzi

Thermostat ndi chowongolera kutentha kwa antifreeze mu dongosolo lozizirira injini. Imafulumizitsa kutentha kwa injini ndikusunga njira yotenthetsera yofunikira.

Choziziritsa chimayenda munjira yozizirira motsatira njira yayikulu kapena yaying'ono. Thermostat ikasweka, valavu yake imakakamira pamalo amodzi (nthawi zambiri imakwera). Pankhaniyi, dera lalikulu silikugwira ntchito. Ma antifreeze onse amapita mozungulira pang'ono ndipo alibe nthawi yozizirira.

Ngati chotenthetsera chawonongeka, bwalo lozizirira limodzi lokha limayatsidwa

Ndizotheka kudziwa kuti thermostat ndi yolakwika motere.

1. Imitsani injini ndikutsegula chitseko chagalimoto.
2. Pezani mapaipi a thermostat ndikuwagwira pang'onopang'ono kuti musawotche.
3. Ngati chitoliro cholumikizidwa ndi radiator yayikulu ndi yotentha kuposa ena, ndiye kuti thermostat ndi yolakwika.

Ngati chotenthetsera chawonongeka mkati mwa mzindawo, muyenera kuyendetsa galimoto kupita kugalimoto yapafupi ndikuisintha. Kupanda kutero, muyenera kupitiriza kuyendetsa galimoto mosamala, nthawi ndi nthawi (makilomita 5-6 aliwonse) ndikuwonjezera thanki yokulitsa ndi madzi. Thirani madzi mu thanki pokhapokha injini ikazizira. Mwanjira imeneyi, mutha kupita kugalimoto yapafupi ndikusintha thermostat.

Kanema: kuwonongeka kwa ma thermostat

Kuphulika kwa antifreeze mu thanki yowonjezera

Mavuto a radiator

Rediyeta imasiya kugwira ntchito moyenera muzochitika zitatu.

1. M'kupita kwa nthawi, sikelo imawonekera pa machubu a radiator ndipo kutentha kwawo kumachepa. Pang'onopang'ono, kuchuluka kwa mapaipi otsekedwa kumawonjezeka (pogwiritsa ntchito antifreeze yotsika, izi zimachitika mofulumira), ndipo mphamvu yoziziritsa ya radiator imachepa.
2. Dothi limalowa mu radiator ndipo mapaipi amatsekeka. Kuyenda koziziritsa mu nkhani iyi kumachepetsa kwambiri (kapena kuyimitsidwa kwathunthu). Kutentha kwa antifreeze kumakwera ndikuwira.
   

   Radiator yaphimbidwa ndi dothi ndipo ikufunika kuthamangitsidwa mwachangu

3. Chikupiza chozizira chikalephera, ma radiator sangathe kuziziritsa pawokha pawokha kutentha komwe kumafunikira. Ndizotheka kudziwa kuti ndi fan yomwe ili ndi vuto ndi khutu. Ngati sichiyatsa, injiniyo idzayenda mwakachetechete modabwitsa.

Muzochitika zonsezi, mutha kupitiliza kuyendetsa ndi maimidwe okhazikika pamakilomita 7-8 aliwonse.

Antifreeze wabwino kwambiri

Mukamagwiritsa ntchito zoziziritsa kukhosi zotsika, pampu ikhala yoyamba kuvutika. Idzayamba dzimbiri, ma resinous deposits adzawonekera. Chifukwa cha cavitation yamphamvu, imatha kugwa.

Cavitation mukamagwiritsa ntchito antifreeze yotsika kwambiri imawononga mpope

Zotsatira zake, pompopompo imazungulira pang'onopang'ono kapena kuyimitsa palimodzi. Antifreeze imasiya kuzungulira kudzera munjira zozizirira za injini ndipo imatenthetsa mwachangu ndikuwira. Kutentha kumawonedwanso mu thanki yowonjezera.

Kuphatikiza apo, choyikapopopocho chimatha kusungunuka mu antifreeze yotsika kwambiri. Pali zochitika pamene choziziritsa kukhosi chinakhala chaukali kwambiri chomwe chinayambitsa dzimbiri zamphamvu zamkati mwa mpope ndikuziwononga m'masiku ochepa. Pazifukwa izi, shaft yapampu imapitilirabe kuzungulira popanda chopondera. Kuthamanga kwa dongosolo lozizirira kumatsika, antifreeze imasiya kuzungulira ndikuphulika.

Kuyendetsa galimoto yokhala ndi pampu yolakwika kumakhala pafupifupi nthawi zonse kumabweretsa kuwonongeka kosasinthika kwa injini. Choncho, ngati mpope wawonongeka, muyenera kunyamula galimotoyo kapena kuyimbira galimoto.

Kutulutsa thovu antifreeze

Chozizira mu thanki yowonjezera sichikhoza kuwiritsa, komanso chithovu popanda kuwonjezera kutentha. Antifreeze imakhalabe yozizira, koma chipewa choyera cha thovu chikuwonekera pamwamba pake.

Antifreeze mu thanki yowonjezera imatulutsa thovu pamene mpweya ulowa mu dongosolo

Zifukwa zazikulu zotulutsa thovu ndi izi.

1. Antifreeze wabwino kwambiri.
2. Kusakaniza mitundu iwiri yozizirira - posintha, antifreeze yatsopano idatsanulidwa m'mabwinja akale.
3. Kugwiritsa ntchito antifreeze sikuvomerezedwa ndi wopanga magalimoto. The mankhwala katundu ozizira kuchokera kwa opanga osiyanasiyana akhoza kusiyana kwambiri. Choncho, mukamachotsa antifreeze, muyenera kudzidziwa bwino ndi katundu wake, zomwe zimayendetsedwa mu bukhu la galimoto.
4. Kuwonongeka kwa cylinder block gasket. Pamene gasket yavala, mpweya umayamba kuyenda mu cylinder block. Tizilombo tating'onoting'ono ta mpweya timalowa m'njira yozizira ndikupanga thovu, lomwe limawonekera mu thanki yokulitsa.

Muzochitika zitatu zoyamba, ndikwanira kukhetsa antifreeze yakale kuchokera kudongosolo, kusungunula ndikudzaza ndi zoziziritsa kukhosi zatsopano malinga ndi malingaliro a opanga.

Pomalizira pake, gasket yowonongeka iyenera kusinthidwa. Kuti mudziwe kuti ndi gasket yomwe yawonongeka, muyenera kuyang'anitsitsa mutu wa silinda. Ngati mafuta akuwoneka pamenepo, ndiye kuti gasket yatha.

Zotsatira za kutentha kwa antifreeze

Pamene antifreeze zithupsa, injini kutenthedwa. Akatswiri amasiyanitsa magawo atatu a kutentha kwambiri: otsika, apakati ndi apamwamba.

Kutentha pang'ono kumawonedwa pamene injini ikugwira ntchito ndi antifreeze yophika kwa mphindi zosapitirira zisanu. Kuwonongeka kwakukulu panthawiyi, mwinamwake, sikudzachitika.

Pakuwotcha kwapang'onopang'ono, injini iyenera kuthamanga ndi antifreeze otentha kwa mphindi 10-15. Pomwe:

• kutayikira kumawonekera mu radiator yayikulu;
• mapaipi a dongosolo lozizirira amaphulika, ndipo kutulutsa kwa antifreeze yotentha kumayamba;
• mphete za pistoni zimatha kuchepa kwambiri, chifukwa chake kugwiritsa ntchito mafuta kumatha kuwirikiza kawiri;
• kulimba kwa zisindikizo zamafuta kumasweka ndipo mafuta amatuluka.

Ngati injiniyo yatenthedwa kwambiri, imatha kuphulika. Ngakhale izi sizinachitike, zotsatira zake zingakhale zoopsa:

• ma pistoni mu injini amasungunuka ndi kutentha;
• mitu ya silinda ndi yopunduka;
• magawano pakati pa mphete za pistoni awonongekeratu, ndipo mphetezo zimawotchedwa wina ndi mzake;
• mipando ya valve imasweka ndi kugwa;
• ma valve ndi opunduka;
• cylinder block gasket yatenthedwa pang'ono kapena kwathunthu.

Choncho, kuthekera kwa antifreeze kuwira mu thanki yowonjezera kumadalira zinthu zambiri. Zinthu zina zimachotsedwa mosavuta, zina zimafuna kulowererapo kwa akatswiri. Mulimonsemo, kutenthedwa kwa injini kuyenera kupewedwa. Posachedwa dalaivala awona kuti antifreeze ikuwira, zimakhala zosavuta kuthana ndi zotsatira zake.
