Coolants kwa dongosolo magetsi. Zoletsa kuwuma kwa Kutentha: mtengo

Monga ulamuliro, pamaso pa Kutentha nyengo, eni mabizinezi mafakitale kapena nyumba m'tawuni akuganiza bwanji kusankha kutentha ufulu dongosolo Kutentha ndi kuti agwire mawerengedwe a kuchuluka kwake. Pamene madzi ntchito ngati coolant mu nyengo yozizira pali chiopsezo chachikulu cha kuwononga mapaipi ndi radiators, komanso dongosolo defrost. Thirani yoyenda yokha Kutentha dongosolo mu makampani mafakitale ndi madzi ali osavomerezeka komanso chifukwa ndi amasiya mwadzidzidzi.

Kodi kusankha coolant?

Kusankha bwino zoletsa kuwuma madzi, m'pofunika kulabadira nkhani zosiyanasiyana izi.

• Kodi zinthu zakonzedwa ntchito dongosolo Kutentha?
• Kodi inu kupeza kuti agwire refueling Kutentha dongosolo zoletsa kuwuma?
• ndi malire a kutentha kwa madzimadzi kufalitsidwa dongosolo la chamoyo mwake chiyani?

Pakali pano, sitingathe amanena kuti pali zoletsa kuwuma kuti ndi abwino kwa machitidwe onse popanda yekha. Onse amene akudziwika kutentha kutengerapo madzi kachitidwe Kutentha ndi ubwino ndi kuipa ndipo anafuna kuti ntchito zinthu mosamalitsa kumatanthauza.

Malamulo zofunika chifukwa chosankha

malamulo amenewa angathandize kuti kusankha wapamwamba ndi otetezeka coolant.

• Madzimadzi ayenera kunyamulidwa mu nthawi yochepa pazipita zotheka kuchuluka kwa kutentha, mwakuti zabwino kutentha kutengerapo sing'anga msanga pochitika lonse opaleshoni dongosolo njira, potero kuonetsetsa kuyamba mwamsanga dongosolo ndipo, chotero, ndi Kutentha chipinda. Qdim a muyezo waukulu ndi khalidwe la coolant mlingo kufalitsidwa.
• Yozizira amadzimadzi kachitidwe Kutentha sayenera poizoni ndi zosafunika kwa flammable. Izi osati pofuna kupewa ngozi anu komanso kuteteza okhalamo mavuto amene imakhudzana ndi volatilization kapena moto utsi poizoni.
• Kuonjezera cangu, mu mawu ena, mu dongosolo makope coolant, izo chofunika kuti madzi anali viscous.
• Kutentha kutengerapo dongosolo Kutentha kukhala kothandiza ngati n'kotheka, ayenera kukhala wabwino matenthedwe madutsidwe.
• Apamwamba zoletsa kuwuma si chifukwa dzimbiri, si monga heaters zamakono zonse ndi chitetezo chokwanira ndi chodabwitsa.
• Kusankha coolant, ayenera kutsatira mfundo za chuma wololera ndi kulingalira - kuphatikiza mulingo woyenera wa mtengo ndi khalidwe.

madzi

Wa zakumwa zonse m'dziko madzi achilengedwe boma ali apamwamba enieni kutentha - pafupifupi kwinakwake 1 kcal / (makilogalamu × deg). M'mawu ena, ngati kilogalamu imodzi ya madzi usavutike 90ºC kutentha ndi ndiye utakhazikika kuti 70ºC mu Redieta mu chipinda chimene usavutike ndi wagawo izi, chitani 20 kcal kutentha.

Madzi Kutentha dongosolo ali mkulu kachulukidwe (917 makilogalamu / mamita ^3), imene yozizira kapena Kutentha yafupika. Dziwani kuti madzi ndi chachibadwa madzi kuti ndi tiwonjezere pansi yozizira Kutentha.

Toxicological ndi zachilengedwe makhalidwe a madzi mwachuluka kuposa magawo amenewo, amene ali khalidwe la coolants aliyense kupanga - Ngozi Yeniyeni amasulidwe dongosolo Kutentha, izo sizigwira kudzetsa mavuto pa moyo wa banja, ngati kugwa mwachindunji pa thupi la munthu.

Amenewa kutayikira koyamba buku la madzi kuti achire lophweka - zokwanira basi kutsanulira kuchuluka chofunika malita kuwonjezeka thanki Kutentha dongosolo.

mitundu ya zoletsa kuwuma

Ndi yaikulu zoletsa kuwuma mu dongosolo Kutentha kunyumba - ndi dzina onse pamodzi kuphatikiza kwa zinthu amaundana pa zina kutentha otsika. Komanso chidwi n'chakuti zoletsa kuwuma, amene angagwiritsidwe ntchito mu kachitidwe munthu Kutentha, anaonekera osati kale. Komabe, eni zambiri zatchatchatcha ndi nyumba ndi Kutentha munthu kuganizira kugwiritsa ntchito zinthu ndi katundu wa deta, dongosolo sakutero peremerzala.

Ngakhale kuti lero msika amapereka zambiri zimene mungachite mu zoletsa kuwuma kachitidwe Kutentha kwa opanga osiyana, ambiri njira izi zopangwidwa kuchokera ku zipangizo zitatu - propylene glycol, glycerol kapena ethylene glycol.

propylene glycol

Ndi sanali poizoni, viscous osakaniza, zomwe ziribe mtundu. Propylene glycol ali ndi zokoma kukoma ndi khalidwe fungo rezkovat. chimake Izi ndiye chimake akadakwanitsira la zoletsa kuwuma, koma osakaniza ofotokoza mtengo ndithu.

glycerol

Kutentha kutengerapo dongosolo Kutentha zochokera glycerol ndi viscous madzi kuti ali ndi kukoma pang'ono wokoma, koma alibe fungo. Zinthu zimenezi si poizoni ndi milandu poyizoni n'zochepa kwambiri. Komanso, glycerin amasungunula mwangwiro, ndipo ngati dongosolo Kutentha amagwiritsa madzi otchezedwa, pamenepo padzakhala mkate.

ethylene glycol

Nkhanizi ndi polyol, alibe fungo ndi mtundu, koma ali ndi zokoma kukoma. Ethylene glycol ndi poizoni kwambiri ndipo ngakhale pamene ntchito pang'ono kungachititse kuti poyizoni kwambiri, zomwe nthawi zambiri kumatsogolera ku ziwalo kapena imfa.

Ngakhale kawopsedwe, ndi Kutentha dongosolo la nyumba payekha coolant ndi yotsika mtengo, kotero ambiri ofunika. Pamene ntchito osakaniza zimenezi zimafuna chisamaliro chapadera, ndipo mu dongosolo zida, malangizo onse ayenera kukwaniritsa kuletsa madzi kulowa madzi abwino ndi kutayikira zotheka.

Zoletsa kuwuma kwa Kutentha: mtengo

Kudziwa mtengo wa dongosolo Kutentha ndi zoletsa kuwuma, ayenera kudziwa buku wonse wa dongosolo, muyenera kuwerenga ndi malire a 10-15%.

Tiyenera kuziganizira:

• yardage ndi chiwerengero cha mapaipi, komanso awiri awo;
• buku la coolant mu dongosolo chachikulu (thanki thambo Kutentha, kukatentha).

banja zoletsa kuwuma kwa Kutentha machitidwe mtengo zimadalira dziko kupanga, zikuchokera njira. formulations anaikira amafuna zochita zina ndi dilution ndi madzi, koma kugula lonse lidzakhala mtengo.

Mwachitsanzo, ethylene glycol zoletsa kuwuma mugule mitundu iwiri.

• "Ofunda House -30" ndi wokonzeka kugwiritsa ntchito amadzimadzi njira zimene zikhoza kugulidwa kwa rubles 70 pa 1 lita imodzi.
• "Ofunda House -65" ndi maganizo, 1 lita imodzi ya umene uli ofunika 85 rubles. Dilution athandizidwe ndi njirayi ndi yozizira koopsa mfundo kwa -30 ° C mtengo pafupifupi 1 lita imodzi 50 rubles.

Ogula zokonda zimadalira zinthu ndi mtundu wa zinthu zimene amapanga kufalitsidwa Kutentha dongosolo. Kudziŵika kuti ntchito zakumwa si yozizira koopsa kumatha overruns mphamvu chifukwa ndikosatheka madipoziti pa mpanda wa kukatentha ndi piping salt, amene kwambiri kuchepetsa kukonza ndi kukonzanso ndalama. Ndemanga coolant ndi chuma zotheka kuti ntchito magetsi magetsi a malo n'kotheka nthawi yaitali disconnection mphamvu ya magetsi, ndi nyumba dziko ndi zing'onozing'ono ndi malawi nthawi.
