Saliidaha Gudbinta: soocidda iyo sifooyinka

saliidaha Gear - saliidaha engine class gaar ah loogu talagalay in loo isticmaalo in qanjidhada kala duwan ee baabuurta gudbinta khilaaf, iyo sidoo kale in noocyo kala duwan oo marsho. Motor iyo marsho saliidda soo saaray macdanta ama saldhig dardaro, ka dibna doped leh noocyo kala duwan oo lagu daro, laakiin shuruudaha gudbinta yihiin sare, maxaa yeelay, waxay ku shaqeeyaan ugu rarataan culaysyo badan oo dadajiyaa warqada ah ee meelaha khilaaf. Mid ka mid ah tilmaamayaasha ugu muhiimsan ee saliida oo kale waa awood u leh inay abuuraan filim ka ilaaliya dushiisa of unugyada khilaaf si looga hortago in xiriir farsamo u dhaxeeya. The marsho hypoid saliidaha waxaa loo isticmaalaa, taasoo, gelaysa reaction kiimikada la oogada ee qaybo ka mid ah, iyaga oo ka hortagga skipanie hantiyi guryaha cadaadis ba'an. Inta lagu jiro hawlgalka, saliidaha marsho oxidize oo noqday sumaysan oo u baahan in la bedelo si teelteel ah. Tani waxaa loo arkaa in ay wanaagsan tahay marka saliidda leh u janjeera in si hoose lagu qayilo noqon. Tan iyo soo saarayaasha kala duwan u isticmaalaan daro kala duwan in ay isku daraan waxyaabaha ay aysan heli karin. Marka bedelay unit gudbinta waa in la si fiican maydhin, haddii ay suurtogal tahay isla saliid cusub.

saliidaha Gear ayaa la tilmaamay inay sidoo kale ku nafwaayay ama by Performance. Sayidka, sida ay SAE (Association of Automotive Injineerro) ay kala qaybsan yihiin sagaal fasal - shan xagaaga iyo jiilaalka afar (la index W). Waayo, fasalka ku qeexan kasta index nafwaayay. SAE SAE 70W ama 250, tusaale ahaan. Dual index tilmaamay for saliidaha multigrade (SAE 80W-90, iwm).

API (petroleum Institute American) qaybiyaa saliidda ku shubaa 6 fasal, waxayna ku xiran tahay sifooyinka hawl - luugaysku-1 ... luugaysku-6. fasallo waxay la mid yihiin kuwa loo adeegsaday Soviet GOST 17479.2-85 TM1 ... TM6 yihiin. koox shanaad iyo lixaad waxaa loo isticmaalaa geerka hypoid oo ay leeyihiin lubricity ugu sareeya iyo qaab cadaadis ba'an.

Marka aad dooranayso saliidaha marsho, waa in ugu horayn diirada saaraan xaaladaha shaqada. Haddii fasalka ka yar tahay lagama maarmaan, si fudud farsamo guuldareysto, iyo dhibcaha sare ee saliidda waxay leedahay qiime sare, taasoo keeni doonta in overruns kharashka. Waxaa kaloo muhiim ah in la tixgeliyo heerkulka at kaas oo gudbinta shaqayn doonaa, oo arrintan laga duulayo in ay doortaan saliid ah. SAE 85W, tusaale ahaan, ku shaqayn doonaa marka heerkulku si -12 ° C, iyo 85W ayaa si -40 ° C. In idaacadaha si toos ah , dareere hooseeyo-ku nafwaayay gaar ah, sidaa darteed ma engine ama gudbinta saliid waxaa ma khuseeyaan.

Maanta oo ku saabsan suuqa kala duwan oo badan oo soo saarayaasha bixiyaan saliidaha marsho ay - Lukoil, Total, ChevronTexaco, Reksol, Norse iyo kuwo kale oo badan. kala duwan oo ka mid ah lagu daro isticmaalo go'aamiso heerka tayada saliidaha iyo duwan qiimaha ay. Macdanta badanaa waa ka jaban, laakiin waa synthetics yar sida dhab ahaan kasoo horjeeda. tanaasulka A wanaagsan, markaas waxaa jiri lahaa semi-synthetics sida dhexdhexaad ah farxad u dhexeeya labada ugu horreeya. Waxaa sidoo kale waa in ay ka walwalsan faalsada ah iyo saliid ma iibsadaan dukaamada tijaabinaya. Beddel sanduuqa mar walba waa qaali in ka badan in ay qaataan oo saliid ah oo tayo fiican leh, gaar ahaan hadda in bedelka ilaa bedeli iyaga nuugtay by 60 kun oo kilomitir ama in ka badan.
