Saliida baabuurta - sida loo doorto

Ku-buuxinta saliidda mishiinka khaldan waxay sababi kartaa dhaawac halis ah qaybta korontada. Si looga fogaado kharashka dayactirka sare, waxaa habboon in la doorto saliidda saxda ah.

Xeerka ugu horreeya iyo kan keliya ee suulka waa in la raaco talooyinka soo saaraha mishiinka. Unugyada tamarta casriga ah waa habab la sameeyay iyadoo la adeegsanayo tignoolajiyada ugu dambeeyay iyo naqshadooda marka la eego cabirrada si adag u hoggaansamaya qaddar. Sidaa darteed, saliidda casriga ah ee matoorka waa qayb ka mid ah qaab-dhismeedka matoorka, sidaas darteed waa in ay la jaanqaadaan dhammaan curiyeyaasha ku jira farsamada, kiimikada iyo caabbinta kulaylka.

Goorma la beddelayaa saliidda?

Xusuusnow saliidda ku jirta sanduuqa

Inta badan saliidaha maanta la isticmaalo waa saliidaha synthetic, kuwaas oo siinaya ilaalin aad uga wanaagsan iyo qaboojinta qaybaha matoorka marka loo eego saliidaha macdanta. Waxa kale oo ay leeyihiin awood weyn oo ay ku kala furfuraan walxaha qayb ka ah ee ka yimaada habka gubashada, kuwaas oo si sahlan loo qabto hababka sifeynta.

Habka ugu muhiimsan iyo faa'iidada leh marka la barbar dhigo saliidaha macdanta waa viscosity hoose ee saliidaha synthetic, taas oo u ogolaanaysa daboolka saxda ah ee saliidda sagxadaha sariiraha khilaaf ku dhowaad kala duwan oo heerkul ah, gaar ahaan heerkulka hoose, marka saliid kasta oo engine qaro weyn.

Ha ku darin saliidda synthetic saliidda macdanta, iyo haddii ay sidaas tahay, oo leh semi-synthetic.

Sidoo kale, ha u isticmaalin saliidaha synthetic ee matoorada baabuurta da'da ah ee leh masaafada sare, oo hore loogu shaqeyn jiray saliidda macdanta. Saliida synthetic ee la buuxiyey waxay kiiskani keeni kartaa dhibaato weyn, sababtoo ah saabuunta iyo qaybaha nadiifinta ee ku jira ka kooban yahay waxay kala diri doonaan wasakhda urursan iyo kaydka wasakhaysan qaybaha mishiinka. Intaa waxaa dheer, inta badan shaabadihii mishiinnada da'da weyn ayaa laga sameeyay qaabab caag ah oo aan loogu talagelin inay ku shaqeeyaan hababka saliidda synthetic. Sidaa awgeed suurtogalnimada sare ee daadinta saliidda.

Ugu dambeyntii, waxaa sidoo kale mudan in la raaco qaanuunka si loo isticmaalo saliidaha laga helo soosaarayaasha si fiican loo yaqaan oo la aqoonsan yahay, inkastoo qiimaha iibsigu uu ka sarreeyo kuwa kale.

Sannadaha waayo-aragnimada ah had iyo jeer waxay bixiyaan tayada alaabta, taas oo, marka la eego saliidda mishiinka, waxay go'aamisaa waxqabadka iyo nolosha adeegga mashiinka baabuurkeena.

Marka loo eego heerarka SAE ee la aqbalay, viscosity saliidda waxaa lagu muujiyey lambarro laga bilaabo 0 ilaa 60, iyo miisaanka 6-dhibcood "W" (jiilaalka) 0W ilaa 25W ayaa go'aamiya heerkulka uu isbeddesho si aad u badan oo saliiddu u sii dhumucdo sida xaalad marka la bilaabayo mishiinka waxay noqotaa mid aan macquul ahayn.

Ficil ahaan, waa sidatan:

- heerka viscosity 0W, heerkulkani wuxuu u dhexeeyaa - 30 ° C ilaa - 35 ° C,

- 5W - 25 ilaa - 30 ° C,

- 10W - 20 ilaa - 25 ° C,

- 15W - 15 ° C ilaa -20 ° C,

- 20W - 10 ° C ilaa -15 ° C,

-25 W - laga bilaabo -10 ° C ilaa 0 ° C.

Qaybta labaad ee miisaanka (5-dhibcaha miisaanka, 20, 30, 40, 50 iyo 60) ayaa go'aamiya "xoogga saliidda", taas oo ah, sii-haynta dhammaan guryaha ee heerkulka heerkulka sare, i.e. 100°C iyo 150°C.

Tusmada viscosity ee saliidaha dardargelinta waxay u dhexeysaa 0W ilaa 10W, inta badan 10W saliidda ayaa sidoo kale loo soo saaraa sidii semi-synthetic. Saliida lagu calaamadeeyay 15W iyo wixii ka sareeya ayaa badanaa ah saliidaha macdanta.

Dhammaan calaamadahan waxaa laga heli karaa baakadaha saliidda mishiinka kasta, laakiin falanqayntoodu kama jawaabto su'aasha - suurtagal ma tahay in la isku daro saliidda, haddii ay sidaas tahay, waa kuwee?

Dabcan, ma jiraan wax xun oo ku dhici doona mishiinka haddii, iyada oo la ilaalinayo tayada tayada isku midka ah iyo fasalka viscosity, waxaan beddeleynaa calaamad - taas oo ah, soo saaraha. Ka dib marka la wado tiro badan oo kiiloomitir ah, waxa kale oo suurtogal ah in la isticmaalo saliid heerka viscosity wax yar ka sarreeya, i.e. cufan. Waxay si fiican u xidhi doontaa mishiinka, iyada oo hagaajinaysa xaaladeeda wax yar, inkastoo ay tahay inaad ogaato inuusan hagaajin doonin mishiinka xiran.
