Nzira yekusarudza mafuta eforogo

Mafuta eforogo anoshandiswa kuchengetedza mashandiro emudhudhudhu emberi maforogo uye anonwisa. Vamwe vatyairi vanototenda kuti zvinokurudzirwa kudira mari yakadaro mumotokari yekuvhundutsa. Ngationei mhando uye maitiro eboka iri remafuta.

Mamiriro ekushanda eforogo yekuvhundutsa mudhudhudhu

Forogo yekumberi inhengo mbiri dzetubula refu dzinotsigira vhiri remberi remudhudhudhu. Zvikamu izvi zvinokwira nekudzika kuti zvitsivire nzvimbo dzisina kuenzana dzemigwagwa.

Kusiyana nekuvhunduka kwemotokari, musangano wechirimo unobvumira gumbo reforogo kumanikidza uyezve rebound, izvo zvinovandudza kukwira uye kudhonza. Imwe neimwe yekumberi forogo chubhu pamidhudhudhu mizhinji ine chitubu neoiri. Pakati pezana remakore rapfuura, makumbo eforogo aingova chitubu mukati mepombi. Kana chitubu chadzvanyirira kubva kune zvinokanganisa, kumberi kwemudhudhudhu kunoputika.

Mushure mekuvandudzwa kweiyo yekunyorovesa system, maitiro eiyo rebound movement yakava yakanyanya kupfava. Nekudaro, kuti uderedze kuvhunduka, panofanira kunge paine incompressible fluid musystem inogona kutora mitoro yekuvhunduka zvakanaka: forogo mafuta. Iyo yakajairika dhizaini ine chubhu mukati mega ega shock absorber strut ine maburi nemakamuri anodzora kufamba kweoiri.

Mabasa uye Zvimiro

Pasinei nehupamhi hwezvigadzirwa zvinopihwa, kune zvakawanda zvisizvo uye zvisinganzwisisiki muchinangwa chayo uye parameters. Saka, zvinodikanwa zvekushanda kwemafuta eforogo zvinosanganisira:

1. Guarantee yakakwana forogo kunyorovesa uye kugadzikana pane yakakura tembiricha renji.
2. Kuzvimirira kwemaitiro emafuta kubva pakugadzira forogo.
3. Kudzivirira kuumbwa kwefuro.
4. Kusabatanidzwa kwezvinokuvadza pazvikamu zvesimbi zvekuvhunduka uye forogo.
5. Kemikari inertness yekuumbwa.

Ese mabhureki emafuta eforogo yemudhudhudhu ndeye hydraulic fluid, saka, zvichienderana nemhando yavo, kunyange mamwe-akawanda-chinangwa maindasitiri oiri zvinoenderana neGOST 20799-88 ane viscosity yakakodzera anogona kushandiswa. Ndapota cherechedza kuti sezvo viscosity yemafuta inowedzera, foloko ichadzokera kunzvimbo yayo yepakutanga zvishoma nezvishoma. Kune rimwe divi, sezvo viscosity inowedzera, kuita kwemafuta kunowedzera, kunyanya kana uchityaira mumigwagwa ine hutsinye, yemotocross midhudhudhu.

Nzira yekusarudza mafuta eforogo?

Chokutanga pane zvose, nekuda kwe viscosity yayo. Sezvaunoziva, kinematic viscosity inoyerwa mumacentistoke (cSt) uye inomiririra mwero wekuyerera kwemvura kuburikidza nepombi inogadziriswa yechimwe chikamu. Mukuita, iyo inonyanya kushandiswa dimension ndeye mm2/s.

Mafuta eforogo ari pasi peAmerican Society of Automotive Engineering (SAE) zviyero, izvo zvine chekuita neviscosity kukosha pane yakapihwa tembiricha (kazhinji 40 ° C) kune density yechigadzirwa uye huremu. Huremu muchirungu huremu; Kubva patsamba yekutanga yezwi iri, mazita emhando dzemafuta eforogo anoumbwa. Saka, kana uchifunga nezvemafuta emudhudhudhu maforogo emhando 5W, 10W, 15W, 20W, nezvimwewo, zvinofanirwa kuyeukwa kuti, semuenzaniso.

Huremu hweoiri muforogo hunotarwa neindasitiri chiyero chinoshandiswa muhydraulic masisitimu inonzi Saybolt Seconds Universal (SSU). Nehurombo, kuda kwevagadziri vakakura kunowanzo tungamira mukuvhiringidzika pamafuta eforogo. Aya anotevera anonyorerana eiyo viscosity paramita akaedzwa akaiswa:

Unhu	Chaiyo viscosity kukosha, mm2/s pa40 °C, zvinoenderana neASTM D 445 yezvigadzirwa zvemhando.
Rock shock	mvura molybdenum	Motul	Motorex mujaho weforogo 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

Chii chinogona kutsiva mafuta eforogo?

Iyo yakanyanya kucherekedza viscosity chiyero inoshandiswa kugadzirisa oiri, saka mukuita iwe unogona kuwana yakajairwa 7,5W kana 8W "iwe pachako" nekusanganisa akajairika maoiri mumaindasitiri muzvikamu zvinodiwa.

Nokuda kwekushanda kwechigadzirwa mumamiriro ezvinhu chaiwo ekushanda, haisi iyo viscosity value pachayo inokosha, asi iyo inonzi viscosity index. Inowanzo kuratidzwa muSaybolt Seconds Universal Scale (SSU) pa100 ° C. Ngatitii nhamba dziri mumudziyo dzinoverenga 85/150. Izvi zvinoreva kuti kukosha kweSSU kwemafuta pa 100 ° C ndeye 85. Kuonekwa kwemafuta kunoyerwa pa40 ° C. Nhamba yechipiri, 150, kukosha kunoratidza mutsauko wekuyerera pakati pematembiricha maviri, iyo inosarudza iyo inonzi viscosity index.

Izvi zvine chekuita nei nemaforogo emidhudhudhu? Iko kukweshera kunoitwa nekutsvedza kwezvikamu zvesimbi uye kumashure uye kumashure kufamba kwemafuta kunowedzera tembiricha mukati megungano. Kuwanda kwehuremu hweoiri hunoramba huripo, kashoma kuti kunyorovesa forogo kuchinje.

Naizvozvo, zvinokwanisika kutsiva mafuta eforogo nemafuta emuindasitiri nekubatanidza mamakisi ayo zvinoenderana nemamiriro ekushanda emudhudhudhu wako.

Nekumwe kuchengetedza, musimboti uyu unogona kushandiswa kune dzimwe mota (kunze kwemudhudhudhu wemujaho).
