Mokelikeli oa Brake
Tse ka hare
Ho tloha nalaneng ea mohala oa brake fluid ea Shell
Morao koana ka 1833, ho ile ha buloa k'hamphani e nyenyane London, e kopanyang thekiso ea li-gizmos tsa khale le ho kenngoa ha likhetla tsa leoatle. Marcus Samuel, mothehi le eo e kileng ea e-ba mong'a pokello e pharaletseng ea lintho tsa khale, o ne a sa tsebe ka nako eo hore k'hamphani ea hae ea Shell e tla fetoha e 'ngoe ea likhoebo tse tsebahalang haholo tsa matla, petrochemical le merafo.
Tsoelo-pele ea letšoao e bile ka potlako. Qalong, majalefa a Samuele, a neng a thehile maqhama a haufi le basebetsi-’moho le ’ona ba tsoang linaheng tse ling, a ile a khona ho tseba ho fana ka mechine le thepa, ’me butle-butle a kena indastering ea oli. Ho fihlela lilemong tsa bo-1970, ho bile le tsoelo-pele e potlakileng ea theknoloji ea Shell, tlhophiso ea eona ea sebopeho. Ho ile ha hlaha lihlahisoa tse ncha tse ntseng li eketseha, li-depositi tse ncha li ile tsa ntlafatsoa, likonteraka tsa phepelo ea mafura li ile tsa phethoa, matsete a khothatsoa. 'Me bohareng ba lilemo tsa bo-1990, ha ho ne ho e-na le ho qhoma ho hoholo lefatšeng ka bophara tlhahiso le nts'etsopele ea mafura a maiketsetso a mokelikeli, ho tšoenyeha ho ile ha khona ho hlahisa mokelikeli o phethahetseng oa brake ho felisa basebelisi. E ne e khetholloa ka ts'ebetso e phahameng le theko e tlaase.
Mme Shell brake fluid e ka khahlisa bakhanni ba likoloi joang kajeno mme ke mefuta efe ea sehlahisoa see e teng?
Sekhahla sa brake fluid
Shell Donax YB - moleng oa pele oa maroki a maroki a tsoang ho Shell. E etselitsoe li-drum le disc brakes. E ne e na le viscosity e tlase mme e sebetsa hantle haholo. E entsoe motheong oa polyethylene glycol ka tšebeliso ea oli ea bohlokoa le li-additives. Butle-butle ea ntlafala. Ke kamoo mokelikeli oa moloko o latelang o ileng oa hlaha kateng.
Brake Mokelikeli le Clutch letheba4 ESL ke mohala o mocha oa lihlahisoa tsa premium. E hlahisoa ka ho khetheha Belgium, ho latela litekanyetso tsa ISO, FMVSS-116, SAE.
Ho ea ka litšoaneleho tsa eona, Shell Brake fluid e hlahisitsoeng e na le viscosity e tlase, ka hona e khothaletsoa hore e sebelisoe tsamaisong ea brake le hydraulic drive ea likoloi tse nang le li-anti-lock le sistimi e tsitsitseng ea elektroniki.

Brake fluid e loketse ho sebelisoa:
- Ka literaka tse boima bo mahareng le thepa e khethehileng.
- Likoloing.
- Ka lithuthuthu.
E ka nkoa e le ea bokahohle, e loketse ho sebelisoa lehlabula le mariha.
Melemo ea Shell Brake Fluid
Haeba u ithuta mamello le litifikeiti tse fumanehang bakeng sa Shell brake fluid, u ka khetholla lihlopha tse latelang tsa sehlahisoa:
| E tloaelehileng | Sehlopha |
| USA FMVSS - 116 | DOT4 |
| AS/NZ | Sehlopha sa 3 |
| JIS K 2233 | Sehlopha sa 4 |
| SAE | J1704 |
| ISO 4925 | Sehlopha sa 6 |
Ho phaella moo, melemo e latelang e lokela ho hatisoa:
- E ka sebelisoa maemong a ka tlase ho zero ka lebaka la metsi a tlase le viscosity e phahameng ea ntho ea viscous.
- Ho sebelisoa ha mokelikeli maemong a mocheso a eketsehang hoa khoneha. Sehlahisoa se khetholloa ke ntlha e phahameng ea ho belisa, e tla thibela ho thehoa ha seo ho thoeng ke mouoane oa mouoane tsamaisong ea hydraulic.
- Theko e theko e tlaase - ntho e hlahisoa fekthering ea rona, e fuoang Russia ka barekisi ba molao.
- E na le thepa e khahlanong le kutu, e lumellang esita le ka tšebeliso e tloaelehileng le ea nako e telele ea likoloi ho thibela nts'etsopele ea mekhoa e senyang tsamaisong.
- E nkoa e le mokelikeli o feto-fetohang o ka bapisoang le lik'hemik'hale tse ling tsa DOT 3 le DOT 4.
Ka hona, ka ho sebelisa lets'oao la brake le tšoailoeng ka logo ea khetla e bosehla bo bofubelu, bakhanni ba likoloi ba tla khona ho sireletsa likarolo le likopano tsa sistimi ea hydraulic le phetiso ho tsoa ho kutu. Ka nako e ts'oanang, ba tla ba le bonnete ba hore ho na le braking e ntle le e potlakileng le ts'ebetso ea nako e telele, e sa sitisoeng ea koloi ea bona.
