Moyo wautali wautumiki wozizirira
Ndizovuta kukhulupirira, koma 34 peresenti yokha. mphamvu yomwe imapezeka chifukwa cha kuyaka kwa mafuta-mpweya wosakaniza imasandulika kukhala mphamvu yothandiza, i.e. mphamvu zamakina. Chithunzichi chikuwonetsa, kumbali imodzi, momwe injini yagalimoto imacheperachepera, ndipo mbali inayo, mphamvu zomwe zimawonongeka kuti zitenthe. Chotsatiracho chiyenera kufulumizitsidwa mwamsanga kuti chiteteze kutenthedwa ndipo potero kusokoneza injini.
Glycol madzi
Kuti muziziritse bwino injini yagalimoto, ndikofunikira kugwiritsa ntchito chinthu chomwe chimatha kuyamwa bwino ndikutulutsa mphamvu zochulukirapo. Izi sizingakhale, mwachitsanzo, madzi, chifukwa chifukwa cha katundu wake (amaundana pa 0 ° C ndi kuwira pa 100 ° C), amachotsa kutentha kwakukulu m'dongosolo. Choncho, makina oziziritsa magalimoto amagwiritsa ntchito 50/50 osakaniza madzi ndi monoethylene glycol. Kusakaniza kumeneku kumadziwika ndi kuzizira kwa -37 ° C ndi kutentha kwa madigiri 108 C. Cholakwika chofala ndi kugwiritsa ntchito glycol yokha. Chifukwa chiyani? Zikuoneka kuti mphamvu bwino kuchotsa kutentha ndiye limawonongeka, ndipo undiluted glycol amaundana pa kutentha yekha -13 madigiri C. Choncho, kugwiritsa ntchito glycol koyera kungayambitse injini kutenthedwa, zomwe zingachititse ngakhale kupanikizana kwake. . Kuti mupeze zotsatira zabwino, sakanizani glycol ndi madzi osungunuka mu chiŵerengero cha 1: 1.
Ndi corrosion inhibitors
Akatswiri amalabadira kuyera kwa zinthu zomwe zimagwiritsidwa ntchito kuziziritsa injini. Choyamba, tikukamba za chiyero cha glycol. Kugwiritsiridwa ntchito kwa otsika otsika kumathandizira kuti pakhale malo opangira dzimbiri mu dongosolo lozizira (chifukwa cha mapangidwe a acidic mankhwala). Chofunika kwambiri pamtundu wa glycol ndi kukhalapo kwa zomwe zimatchedwa corrosion inhibitors. Ntchito yawo yayikulu ndikuteteza dongosolo loziziritsa ku dzimbiri komanso kupanga ma depositi owopsa. Corrosion inhibitors amatetezanso choziziritsa kukhosi kuti chisakalamba msanga. Kodi zoziziritsa kuziziritsa m'ma radiator zagalimoto ziyenera kusinthidwa nthawi yanji? Zonse zimadalira wopanga ndi zowonjezera zomwe zimagwiritsidwa ntchito mwa iwo - classical kapena organic.
Kuyambira zaka ziwiri mpaka zisanu ndi chimodzi
Zozizira zosavuta zimakhala ndi zowonjezera zowonjezera monga silicates, phosphates kapena borates. Kuipa kwawo ndi kuchepa kwachangu kwa zinthu zoteteza komanso kupanga madipoziti mu dongosolo. Pakuti madzimadzi, Ndi bwino kusintha ngakhale zaka ziwiri zilizonse. Mkhalidwewu ndi wosiyana ndi madzi okhala ndi organic compounds (otchedwa carbon compounds), omwe amadziwikanso kuti madzi amoyo wautali. Zochita zawo zimatengera mphamvu ya catalytic. Mankhwalawa samachita ndi zitsulo, koma amangoyimira pakati. Chifukwa cha izi, amatha kuteteza bwino dongosololi kuti likhale lopangidwa ndi matumba a dzimbiri. Pankhani ya madzi a moyo wautali, moyo wawo wautumiki ndi zaka zisanu ndi chimodzi, kapena pafupifupi 250 zikwi. km kuthamanga.
Chitetezo ndi kusalowerera ndale
Zozizira bwino kwambiri zokhala ndi ma organic carbon compounds sizimangoteteza dongosolo ku chiwopsezo cha dzimbiri, komanso zimalepheretsa mapangidwe owopsa omwe amasokoneza kuzizira. Zamadzimadzizi zimachepetsanso mpweya wotulutsa acidic womwe ungalowe munjira yozizirira kuchokera kuchipinda choyaka. Komanso, zomwe zili zofunikanso, sizimayenderana ndi mapulasitiki ndi ma elastomer omwe amagwiritsidwa ntchito muzozizira zamagalimoto amakono. Madzi okhala ndi zowonjezera organic ndi bwino kupewa chiopsezo cha kutentha kwa injini kuposa anzawo amchere, ndichifukwa chake akuchulukirachulukira m'malo mwawo.
