Kodi kusankha mafuta mphanda?

Mkhalidwe wogwirira ntchito wa foloko yamoto wanjinga yamoto

Foloko yakutsogolo ndi zidutswa ziwiri zazitali za tubular zomwe zimagwira gudumu lakutsogolo pa njinga yamoto. Zigawozi zimayenda m'mwamba ndi pansi kuti zithetse mabampu omwe ali pamtunda.

Mosiyana ndi chotsitsa chamoto, kasupe pamsonkhanowo amalola mwendo wa foloko kuti upanikizike ndikuyambiranso: izi zimathandizira kukwera komanso kuwongolera. Iliyonse ya machubu akutsogolo a njinga zamoto zambiri imakhala ndi kasupe ndi mafuta. Kalelo pakati pa zaka zana zapitazi, miyendo ya mphanda inali chabe kasupe mkati mwa chitoliro. Pamene wothinikizidwa pa kasupe ku zotsatira, kutsogolo kwa njinga yamoto bounced.

Pambuyo pa chitukuko cha damping system, ndondomeko ya kayendedwe kameneka kamakhala kosavuta. Komabe, kuti muchepetse kugwedezeka, makinawo amayenera kukhala ndi madzimadzi osasunthika omwe amatha kuyamwa bwino - mafuta a foloko. Mapangidwe ofala kwambiri ndi omwe mkati mwa mwendo uliwonse wotsekemera pali chubu chokhala ndi mabowo ndi zipinda zomwe zimayendetsa kayendedwe ka mafuta.

Ntchito ndi mawonekedwe

Ngakhale kuti pali zinthu zambiri zomwe zimaperekedwa, pali zosiyana zambiri komanso zosatsimikizika pamatchulidwe ake ndi magawo ake. Chifukwa chake, zofunikira pakugwira ntchito kwamafuta a foloko ndi:

1. Kuonetsetsa kuti mulingo woyenera kwambiri damping mafoloko ndi bata la ntchito yawo pa osiyanasiyana kutentha.
2. Kudziyimira pawokha kwa magwiridwe antchito amafuta kuchokera pamapangidwe a foloko.
3. Kupewa thovu.
4. Kupatula zowononga zowonongeka pazigawo zachitsulo za chotsitsa chogwedeza ndi mphanda.
5. Chemical inertness wa zikuchokera.

Mitundu yonse yamafuta amtundu wa njinga zamoto ndi madzi amadzimadzi, chifukwa chake ngakhale mafuta ena opangira mafuta opangira mafuta malinga ndi GOST 20799-88 okhala ndi mamasukidwe oyenera angagwiritsidwe ntchito ngati mtundu wawo. Zindikirani kuti ndi kuwonjezeka kwa kukhuthala kwa mafuta, mphanda udzabwerera ku malo ake oyambirira pang'onopang'ono. Kumbali ina, ndi kukhuthala kochulukira, magwiridwe antchito amafuta amawonjezeka, makamaka poyendetsa misewu yoyipa, panjinga zamotocross.

Kodi kusankha mafuta mphanda?

Choyamba - ndi mamasukidwe ake akayendedwe. Monga mukudziwira, viscosity ya kinematic imayesedwa mu centistoke (cSt), ndipo ndi kuchuluka kwa madzimadzi kudzera mu chubu chokhazikika cha gawo linalake la mtanda. Pochita, dimension mm imagwiritsidwa ntchito nthawi zambiri.²/Ndi. Pankhani yamafuta a foloko, miyezo ya American Society for Automotive Engineering (SAE) imagwira ntchito, yomwe imagwirizanitsa ma viscosity values ​​pa kutentha kwina (nthawi zambiri pa 40). ^°C) ndi kachulukidwe ndi kulemera kwa mankhwala. Kulemera mu Chingerezi kulemera; kuchokera ku chilembo choyambirira cha mawu awa, mayina amtundu wa mafuta a foloko amapangidwa. Choncho, poganizira mafuta mphanda njinga zamoto zopangidwa 5W, 10W, 15 W, 20W ndi zina zotero, tiyenera kukumbukira kuti Mwachitsanzo, mafuta kalasi 10W limafanana ndi mankhwala ndi kukhuthala mwadzina pafupifupi 10 mm.²/ s

Kulemera kwa mafuta a foloko kumatsimikiziridwa ndi miyezo yamakampani yomwe imagwiritsidwa ntchito mumayendedwe a hydraulic otchedwa Saybolt Seconds Universal (SSU). Tsoka ilo, kudzipereka kwa opanga akuluakulu nthawi zambiri kumabweretsa chisokonezo pakati pa zolemba zamafuta a foloko. Makalata otsatirawa a magawo a viscosity adakhazikitsidwa moyeserera:

Kulemba	Mtengo weniweni wa viscosity, mm2/s ku 40 °C, pa ASTM D 445 pazogulitsa zamtundu
	RockSwaka	Liqui Moly	Motuli	Mafuta a Motorex Racing Fork
5W	16,1	17,2	18	15,2
10W	33	29,6	36	32
15W	43,8	43,9	57	46
20W	-	-	77,9	68

Nchiyani chingalowe m'malo mwa mafuta a foloko?

Kuwongolera mafuta kumagwiritsidwa ntchito kwambiri poyesa kuwongolera mafuta, chifukwa chake ndizotheka kupeza "7,5W" kapena 8W "kwa inu nokha" mwa kusakaniza mafuta wamba am'mafakitale molingana ndi zofunikira. Kwa ntchito ya mankhwalawa muzochitika zinazake zogwirira ntchito, si mtengo wa viscosity womwe ndi wofunikira, koma zomwe zimatchedwa viscosity index. Nthawi zambiri amalembedwa pamlingo wa Saybolt Seconds Universal (SSU) pa 100 ^°C. Ganizirani kuti manambala omwe asonyezedwa pa chidebecho amawerengedwa ngati 85/150. Izi zikutanthauza kuti mtengo wa SSU wamafuta pa 100 ^ºC ndi 85. Ndiye kukhuthala kwa mafuta kumayesedwa pa 40 ^°C. Nambala yachiwiri, 150, ndi mtengo wosonyeza kusiyana kwa kuyenda pakati pa kutentha kuwiri, komwe kumatsimikizira ndondomeko ya viscosity yolengeza.

Kodi izi zikukhudzana bwanji ndi mafoloko a njinga yamoto? Mkangano wopangidwa ndi zitsulo zotsetsereka ndi mafuta oyenda uku ndi uku 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, kuphatikiza magiredi ake malinga ndi momwe njinga yamoto imagwirira ntchito.

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