Pehea e hoʻokaʻawale a koho i ka antifreeze excavator?

ʻO ka mea maʻamau, ʻo ke koho ʻana o ka antifreeze e pili ana i kona mahana pale anu. Hoʻokaʻawale ʻia ʻo Antifreeze e kona wahi hau. Inā he -25°C ka helu hau hau, ua kapa ʻia ʻo -25°C antifreeze. He aha ke kiko hau? ʻO ka pae maloʻo ka mahana i hoʻomaka ai ka ʻike ʻana o nā kristal hau ma ka antifreeze. He ʻokoʻa ia mai ka helu hau a me ka wahi ninini o ka ʻaila lubricating. He hiʻohiʻona kūikawā ia o ka hoʻonā wai. ʻO ka maʻamau, ʻoi aku ke kiʻekiʻe o ka helu hau hau ma mua o ka helu hau a me ka helu ninini. Hōʻike ia i ka wela haʻahaʻa e hōʻoia i ka hana ʻole ʻana o ka antifreeze i nā mea paʻa e pili ana i ke kahe. ʻOkoʻa ka ʻikepili no nā ʻano ana ʻokoʻa o kekahi mau hōʻailona. ʻO kahi laʻana, ʻo kahi antifreeze he wahi hau hau o -25°C, kahi wahi hau hau o -33°C, a me kahi wahi hoʻoheheʻe o -30°C. I kēia manawa, ʻo ka papa inoa maʻamau o ka antifreeze ʻo -25 ℃, -30 ℃, -35 ℃, -40 ℃, -45 ℃, -50 ℃ a me ʻehiku mau ʻāpana o ka wai i hoʻopaʻa ʻia (SHO521-92). ʻO nā mea ʻē aʻe, e like me -20 ℃, -16 ℃ a me nā ʻano ʻē aʻe i hoʻokaʻawale ʻia a hana ʻia e nā ʻoihana e like me nā pono maoli.

Pono ke koho o ka antifreeze ma muli o ka mahana ambient. No ka laʻana, inā he -28°C ka mahana haʻahaʻa loa i ka hoʻoilo ma kekahi wahi, e kūpono ana ka antifreeze o -35°C. ʻO ka mea maʻamau, ʻo ka pae maloʻo o ka antifreeze he -10 ° C a i ʻole -15 ° C haʻahaʻa ma mua o ka mahana ambient.

Inā pono ʻoe e kūʻai i ka antifreeze a i ʻolenā lako ʻē aʻe, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa. Inā makemake ʻoe i nā mīkini hana, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou. Ua hoʻolako lōʻihi ʻo CCMIENā huahana XCMGamīkini hana lua limao nā hōʻailona ʻē aʻe.
