Momwe mungasankhire mafuta a foloko

Mafuta a foloko amagwiritsidwa ntchito kuti asunge magwiridwe antchito a mafoloko akutsogolo kwa njinga zamoto ndi zotsekemera zowopsa. Ena oyendetsa galimoto ngakhale amakhulupirira kuti m'pofunika kutsanulira ndalama zimenezi mu absorbers galimoto mantha. Tiyeni tiwone mtundu ndi mawonekedwe a gulu ili lamafuta.

Mkhalidwe wogwirira ntchito wa foloko yamoto wanjinga yamoto

Foloko yakutsogolo ndi mbali ziwiri zazitali za tubular zomwe zimathandizira gudumu lakutsogolo la njinga yamoto. Zigawozi zimayenda m'mwamba ndi pansi kuti zilipire misewu yosagwirizana.

Mosiyana ndi kugwedezeka kwa galimoto, msonkhano wa kasupe umalola mwendo wa mphanda kuti upanikizike ndikuyambiranso, zomwe zimapangitsa kuti kukwera ndi kuyenda bwino. Chubu chilichonse chakutsogolo pa njinga zamoto zambiri chimakhala ndi kasupe ndi mafuta. Pakati pa zaka zapitazo, miyendo ya mphanda inali chabe kasupe mkati mwa chitoliro. Pamene kasupe compresses ku zotsatira, kutsogolo kumapeto kwa njinga yamoto bounces.

Pambuyo pakukula kwa dongosolo lonyowa, njira yolumikizirananso iyi idakhala yosalala. Komabe, kuti muchepetse kugwedezeka, payenera kukhala madzi osasunthika m'dongosolo omwe amatha kuyamwa bwino: mafuta a foloko. Kapangidwe kofala kwambiri kamakhala ndi chubu mkati mwa chiwopsezo chilichonse chokhala ndi mabowo ndi zipinda zomwe zimayendetsa kayendedwe ka mafuta.

Ntchito ndi mawonekedwe

Ngakhale kuti pali zinthu zambiri zomwe zimaperekedwa, pali zolakwika zambiri komanso zosamveka bwino mu cholinga chake ndi magawo ake. Chifukwa chake, zofunikira pakugwira ntchito kwamafuta a foloko ndi:

1. Tsimikizirani kuti foloko ili yabwino kwambiri komanso kukhazikika pa kutentha kwakukulu.
2. Kudziyimira pawokha kwamafuta kuchokera pamapangidwe a foloko.
3. Kupewa kupanga chithovu.
4. Kupatula zowononga zowonongeka pazigawo zachitsulo za chotsitsa chododometsa ndi mphanda.
5. Chemical inertness wa zikuchokera.

Mitundu yonse yamafuta amtundu wanjinga yamoto ndi madzi amadzimadzi, chifukwa chake, kutengera mtundu wawo, ngakhale mafuta ena opangira mafakitale malinga ndi GOST 20799-88 okhala ndi viscosity yoyenera angagwiritsidwe ntchito. Chonde dziwani kuti pamene kukhuthala kwa mafuta kumawonjezeka, mphanda udzabwerera kumalo ake oyambirira pang'onopang'ono. Komano, monga mamasukidwe akayendedwe akuwonjezeka, ntchito mafuta kumawonjezeka, makamaka pamene galimoto m'misewu yokhotakhota, kwa motocross njinga zamoto.

Kodi kusankha mafuta mphanda?

Choyamba, chifukwa cha kukhuthala kwake. Monga mukudziwira, viscosity ya kinematic imayesedwa mu centistoke (cSt) ndipo imayimira kuchuluka kwa madzimadzi kudzera papaipi yokhazikika ya gawo linalake. M'malo mwake, gawo lomwe limagwiritsidwa ntchito kwambiri ndi mm2 / s.

Mafuta a foloko amakhala pansi pamiyezo ya American Society of Automotive Engineering (SAE), yomwe imakhudzana ndi mawonekedwe a viscosity pa kutentha komwe kumaperekedwa (nthawi zambiri 40 ° C) ndi kachulukidwe kazinthu ndi kulemera kwake. Kulemera mu Chingerezi kulemera; Kuyambira chilembo choyambirira cha mawu awa, mayina amafuta a foloko amapangidwa. Choncho, poganizira mafuta a njinga yamoto mafoloko a mtundu 5W, 10W, 15W, 20W, etc., tiyenera kukumbukira kuti Mwachitsanzo.

Kulemera kwa mafuta mu mphanda kumatsimikiziridwa ndi muyeso wamakampani omwe amagwiritsidwa ntchito m'ma hydraulic system otchedwa Saybolt Seconds Universal (SSU). Tsoka ilo, kufuna kwa opanga akuluakulu nthawi zambiri kumabweretsa chisokonezo pamalemba amafuta a foloko. Makalata otsatirawa a magawo a viscosity adakhazikitsidwa moyesera:

Kuyenerera	Mtengo weniweni wa viscosity, mm2/s pa 40 °C, malinga ndi ASTM D 445 pazinthu zodziwika bwino
Kugwedezeka kwa thanthwe	madzi molybdenum	Motul	Motorex racing foloko mafuta
5 W	16.1	17.2	18	15.2
10 W	33	29,6	36	32
15 W	43,8	43,9	57	46
20 W	-	-	77,9	68

Nchiyani chingalowe m'malo mwa mafuta a foloko?

Sikelo yowoneka bwino kwambiri ya viscosity imagwiritsidwa ntchito kuwongolera mafuta, motero mutha kupeza 7,5W kapena 8W wamba "panu" posakaniza mafuta wamba am'mafakitale molingana ndi zofunikira.

Kwa ntchito ya mankhwala muzochitika zenizeni zogwirira ntchito, si mtengo wa viscosity womwe ndi wofunikira, koma zomwe zimatchedwa viscosity index. Nthawi zambiri amawonetsedwa mu Saybolt Seconds Universal Scale (SSU) pa 100 ° C. Tinene kuti manambala omwe ali pachidebe amawerenga 85/150. Izi zikutanthauza kuti mtengo wa SSU wa mafuta pa 100 ° C ndi 85. Kuthamanga kwa mafuta kumayesedwa pa 40 ° C. Nambala yachiwiri, 150, ndi mtengo wosonyeza kusiyana kwa kuthamanga kwa kutentha pakati pa kutentha kuwiri, komwe kumatsimikizira chiwerengero cha viscosity index.

Kodi izi zikukhudzana bwanji ndi mafoloko a njinga yamoto? Kukangana kopangidwa ndi kutsetsereka kwa zigawo zachitsulo ndi kayendedwe ka mafuta kumbuyo ndi kutsogolo kumawonjezera kutentha mkati mwa msonkhano. Kulemera kwa mafuta kukakhalabe kosasintha, m'pamenenso kuti foloko idzasinthe.

Chifukwa chake, ndizotheka kusintha mafuta a foloko ndi mafuta am'mafakitale pophatikiza magiredi ake malinga ndi momwe njinga yamoto imagwirira ntchito.

Ndi kusungitsa kwina, mfundo iyi itha kugwiritsidwa ntchito pamagalimoto ena (kupatulapo njinga zamoto zothamanga).
