Deciphering giya mafuta 80W90
Ngatitarisei muchidimbu maitiro makuru ayo mafuta egiya ane viscosity ye80W90 ane. Iyo SAE J300 standard inotaura zvinotevera.
- Iyo yekudurura nzvimbo isati yarasikirwa yekuzora uye yekudzivirira zvivakwa iri pamwero we -26 ° C. Kana kuchitonhora pasi petembiricha iyi, kusimba kwemafuta emafuta kunodarika muganhu unogamuchirwa we150000 csp inogamuchirwa nemainjiniya eSAE. Izvi hazvirevi kuti girizi inoshanduka kuita aizi. Asi mukuwirirana, ichava souchi hwakakora. Uye mafuta akadaro haangokwanise kuchengetedza akaremerwa friction pairi, asi pachayo ichava chipingamupinyi kune yakajairika kushanda kweyuniti.
- Iyo kinematic viscosity pa100 ° C yeiyi kirasi yemafuta haifanire kuwira pasi pe24 cSt.. Zvinonzwika zvinoshamisa maererano nemayuniti ekutapurirana: tembiricha iri 100 ° C. Kana iyo giya bhokisi kana axle ichidziya kusvika kune tembiricha yakadaro, saka kazhinji pane mamwe matambudziko mumusangano wekutapurirana, kana mutoro unobvumidzwa wakapfuudzwa. Nekudaro, iyo viscosity pa100 ° C inocherechedzwa pano, nekuti iyo firimu remafuta iri pasi pekunetsekana kukuru mumatanho ekusangana uye inogona kupiswa munharaunda kusvika kune tembiricha yakakwira. Uye kana viscosity isingakwani, ipapo firimu ichaputsa nyore nyore uye inobvumira simbi kuti ibatane nesimbi zvakananga, izvo zvichaita kuti kukurumidza kupera kwezvikamu zvegungano. Zvisina kunanga, chikamu che "zhizha" che index chinotarisa tembiricha inobvumidzwa yezhizha, iyo yemafuta ari mubvunzo ndeye +35 ° C.
Kazhinji, viscosity ndiyo chiratidzo chikuru. Ndiye anosarudza maitiro eimwe giya mafuta mune akasiyana tembiricha.
Kukura uye analogues epamba
Chiyero che80W90 giya oiri chinogumira kwete chete nematembiricha, asiwo nezvimwe zvivakwa, senge: kugona kugadzira firimu rakasimba, kuramba kupupa furo uye oxidation, hupenyu hwesevhisi, hutsinye kune rabha uye zvikamu zvepurasitiki. Izvi uye zvimwe zvivakwa zvegiya mafuta zvinotsanangurwa zvakadzama neiyo API standard.
Nhasi muRussia, 80W90 giya maoiri ane API makirasi GL-4 uye GL-5 akajairika kupfuura mamwe. Dzimwe nguva unogonawo kuwana GL-3 class lubricant. Asi nhasi vanenge vakarega zvachose.
Oiri 80W90 GL-4. Inoshandiswa mune akawanda akawiriraniswa magiya mabhokisi uye mamwe mayuniti ekutapurirana emotokari dzepamba uye dzekunze. Inochinjika ne GL-3 kirasi oiri, asi ine yakawedzera yepamusoro pasuru yezvinowedzera, kunyanya yakanyanyisa kumanikidza ekuwedzera. Iine mafuta akanaka uye anodzivirira zvinhu. Inokwanisa kushanda ne hypoid gears, umo mutoro wekusangana haupfuure 3000 MPa.
Mafuta egiya 80W90 kirasi GL-5 maererano neAPI yakatsiva kirasi GL-4, yatove isingachashandi kumotokari itsva. Inochengetedza nekuvimbika hypoid friction pairs nekutamisa kukuru kwematemo, umo mitoro yekubata inodarika 3000 MPa.
Nekudaro, mafuta aya anogona kusagara achishandiswa mumabhokisi egiya akagadzirirwa iyo GL-4 standard. Izvo zvese nezve yakaderera coefficient yekukwesha, iyo inowanikwa kuburikidza neyepamberi yekuwedzera pasuru. Synchronizers yeakareruka manyorerwo ekufambisa anoshanda nekuda kweiyo coefficient yekukwesha. Ndiko kuti, synchronizer inotsikirirwa pagiya uye inofananidzira kumhanya kwekutenderera kweshafts pakarepo magiya asati apinda mugiya. Nekuda kweizvi, kutapurirana kuchaita nyore nyore.
Paunenge uchimhanya pamafuta eGL-5, mabhokisi egiya akawiriraniswa asina kugadzirirwa iyi chiyero anowanzo sangana nekusimba kwegiya shanduko uye hunhu crunch nekuda kwesynchronizer kutsvedza. Kunyangwe iye muridzi wemota achigona kuona kumwe kuwedzera kwesimba remotokari uye kudzikira kwemafuta ekushandisa nekuda kweinooneka yakaderera coefficient yekupokana. Zvakare, masynchronizers anotadza nekumhanyisa nhanho pamabhokisi asina kugadzirirwa kushanda neGL-5 mafuta.
Mamwe mayuniti ekutapurirana anoda kunyorovesa nyore kwesimba-kutumira masisitimu anogona kuzadzwa neGL-5 oiri panzvimbo yeGL-4.
Mutengo wemafuta e80W90 unotanga pa140 rubles pa1 litre. Aya ndiwo marii emafuta akareruka epamba anodhura, semuenzaniso, iyo OilRight brand. Ivhareji yemutengo tag inoshanduka yakatenderedza 300-400 rubles. Mutengo wezvigadzirwa zvepamusoro unosvika 1000 rubles parita.
Iyo yemukati vhezheni ye80W90 oiri zvinoenderana neiyo yekare kupatsanurwa kunonzi TAD-17, maererano neiyo nyowani - TM-4-18 (yakafanana ne80W90 GL-4) kana TM-5-18 (yakafanana ne80W90 GL-5) .
