Kodi mafuta ndi lubricants

Malinga ndi malipoti zosatsimikiza, lubricants ntchito mwa munthu oposa 6 zikwi. Zaka zapitazo. Mafuta kudziwika kwa nthawi yaitali, koma ntchito mu maonekedwe ake angwiro ndi zochepa zapitazi, koma processing wa kulankhula ndi sukupita. Pamene anthu aphunzira pokonza izo, ndiye ife tinatenga yekha palafini, monga chofunika kwambiri - mafuta - ntchito ngati mafuta, kapena kungoti kutenthedwa. Ndipo zili kwa 90% mwa kulemera kwa mafuta zofunika kwambiri.

Koma luso alibe kuima - ndipo tsopano mu ayenga aphunzira kupatutsa mafuta mu tuzigawo twa osiyana. chithandizo wotsatira zidapatsa mafuta wapatali kwa izo, anaitana mafuta kapena mchere. Mu injini ano magalimoto - mkulu mawotchi kutentha katundu, kotero lubricants kwa iwo zofunika kuzikwaniritsa.

Kusintha khalidwe la mafuta lubricating pogwiritsa ntchito Kuwonjezera thereto wa zinthu zapadera (zina). Aliyense zina izi bwino akalozera chimodzi kapena mfundo zingapo. Mwachitsanzo, protivoiznosostoykie zowonjezera anawonjezera kuti lubricants kuchepetsa mlingo wa avale mbali ntchito, ndi kuyeretsa - kuchepetsa madipoziti ndi kuteteza pisitoni mphete kukakamira. Modern lubricating mafuta akhoza kuwerenga vyakujumpha wa ukuwonjezeka.

Ndi osiyanasiyana zina ndi mwayi kuphatikiza iwo ndi kuonjezera osiyanasiyana, amene kupereka opanga. Izi lubricating mafuta amene amatulutsa. Ndipo pambali, panali ochepa a chandamale mtundu wawo - injini, HIV ndi zina. Pamaso kugula lubricating mafuta (ngakhale Mlengi odziwika) kudziwa mfundo za kusankha kwawo.

Lubricants ndi magawo ambiri zafotokozeredwa makhalidwe luso, koma ndi kugula m'pofunika kulabadira yekha kwa awiri a iwo. mafuta apamwamba mlingo limasonyeza ngakhale a galimoto yanu ndi nkhaniyi, ndi kukhuthala - woyenerera ake ntchito mu nyengo imeneyo ndi nyengo.

Kusankha kuti ndi lubricant kudzakuthandizani kulemba pano pa kalasi iliyonse malonda, ndi chimodzimodzi dongosolo indexing lonse. The anafotokoza luso kunja mfundo ndi matanthauzo mwachindunji kukhuthala index motsatira ndondomeko anatengera ndi American Society of Automotive Akatswiri SAE, motero anaganiza kuti kukhuthala adzasonyezedwa pambuyo chodetsa SAE makalata. Amaimira kalata W yozizira sukulu ya utsi ndi lubricants, ndi chilimwe - zimasonyeza yosavuta kukhuthala lapansi.

Palinso muyezo kalembedwe. Mwachitsanzo, pansi pa chikhazikitso cha SAE J300 kubisala makalasi sikisi mode kukhuthala yozizira - 0W, 5W, 10W, 15W, 20W, 25W. makalasi onse awa amayenda kuyamba makina mu chikhalidwe kuzizira, ndi kayendedwe ka mafuta ndi lubricants chikuchitika momasuka mu dongosolo mu kutentha osiyanasiyana -30- + 5 madigiri. Chilimwe mitundu alibe makalata lowonjezera kulemba, koma ndi kuwonjezeka mu kukhuthala mitundu izi magulu a SAE 20, 30, 40, 50, 60.

Tsopano inu mukudziwa chomwe mafuta ndi lubricants, ndi zimene gulu lawo!
