HTHS - chizindikiro cha kukhuthala kwa mafuta

Tiyeni timvetsetse kuti HTHS ndi chiyani komanso momwe imakhudzira.

HTHS - chizindikiro chomwe chimatsimikizira makulidwe a filimu yamafuta m'madera opanikizika kwambiri a injini, monga mwachitsanzo makoma a silinda, nthawi zonse amakhala olemetsa kwambiri panthawi ya pisitoni. Parameter iyi imatsimikiziridwa ngati muyezo pa kutentha kwakukulu kwa madigiri 150. Kuti timvetse bwino tanthauzo la parameter iyi, tidzasanthula lingaliro linanso.

Injini yokhala ndi kusintha kokhazikika kwamafuta komwe kumasunga mulingo wofunikira wa viscosity

Kumeta ubweya wambiri ndi mtengo wamtengo wapatali womwe umasonyeza mphamvu ya filimu yamafuta, yomwe imateteza mbali kuti zisavale. Monga momwe zingawonekere kwa ambiri, koma uku si kugunda kwa pistoni, ndi chiwerengero cha sitiroko chomwe chimagawidwa ndi makulidwe a filimuyi, yoyesedwa mu 1 / s.

Kuchuluka kwa filimu ya mafuta

Makulidwe a kanema wamafuta ali ndi mtengo wake wokwanira. Ikayamba kukhala yopyapyala kwambiri, mikangano imakula ndipo malowo amalumikizana. Ngati kanemayo ndi wochuluka kwambiri, ndiye kuti pali mikangano ikuluikulu, ndiye kuti palibe kuvala, koma kuyeserera kumachepa, chifukwa ndizovuta kwambiri kuti injini isakanize filimuyo.

Kodi makulidwe a filimu yamafuta angakhudze bwanji magwiridwe antchito a injini? Tiyerekeze kuti injini yanu yatha kale makilomita zikwi zingapo, ndipo mu nkhani iyi, injini iliyonse imavala pa makoma a silinda, mphete za pistoni, ndi zina zotero, zomwe zimachititsa kupsinjika kwa injini galimoto yanu ikhoza kugwa, zomwe zimapangitsa kuti mphamvu ziwonongeke. Makamaka pa izi, pali zowonjezera zapadera zomwe zimakulolani kuti muwonjezere makulidwe a filimu yamafuta, kapena mwa kuyankhula kwina, kusintha magawo a HTHS a mafuta, chifukwa chakuti mtunda pakati pa pisitoni ndi silinda yopangidwa chifukwa cha kuvala ndi wodzazidwa ndi filimu ya viscosity yapamwamba, yomwe imapangitsa kuti kusindikiza kwa chipinda choyaka moto kukhale bwino komanso kumapangitsa kuti injini ikhale yabwino.
