Maxay ku kala duwan yihiin saliidaha SP iyo SN?

Sida aynu wada ognahay, saliiddu waxay ka ciyaari kartaa doorka saliidaynta iyo dhimista xidhashada, qaboojinta iyo qaboojinta caawinta, xidhitaanka iyo ka hortagga daadinta, ka hortagga miridhku iyo ka hortagga daxalka, shoogga.

Saliidda saldhigga ah, oo ah qaybta ugu muhiimsan ee saliidda saliidda, waxay go'aamisaa sifooyinka aasaasiga ah ee saliidda saliidda, iyo waxyaabaha lagu daro waxay ka dhigi karaan oo ay wanaajiyaan la'aanta waxqabadka saliidda saldhigga, waxayna siiyaan qaar ka mid ah guryaha cusub. Heerarka kala duwan ee saliidda, waxqabadkeeda tayada ayaa sidoo kale ka duwan.


Markan Master Bang wuxuu ku qaadan doonaa inaad fahamto farqiga u dhexeeya saliidda darajada SN iyo saliidda darajada SP.

Ku saabsan saliidaha darajada SN iyo SP


SN iyo SP waa darajooyinka saliidda, kuwaas oo xarafka hore S uu tilmaamayo in saliiddu ay ku habboon tahay matoorada shidaalka, oo loo yaqaan "saliid engine oil", xarafka labaad wuxuu tilmaamayaa waxqabadka saliidda ee heerka caadiga ah, ka dib siday u kala horreeyaan alifbeetada, ayaa si fiican u shaqaynaysa. Waqtigan xaadirka ah, heerka ugu dambeeyay ee shahaadadan caadiga ah waa SP.

Saliidaha heerka API SP guud ahaan waxay leeyihiin isticmaalka shidaal ka wanaagsan, awood nadiifin heer sare ah iyo kala firdhisanaanta dhoobada, badbaadinta tamarta, ka hortagga sileynta, joojinta kaydka kaarboonka ee piston, oksaydhka, iyo kordhinta tijaabinta xirashada silsiladda waqtiga.


Farqiga u dhexeeya SN iyo saliidaha darajada SP

Marka hore, darajooyinku way kala duwan yihiin: SP waa heerka ugu sarreeya ee saliidda hadda jirta, SNna waa heerka labaad ee saliidda. Marka labaad, filimka saliidda: filimka saliidda ee SP wuu xoog badan yahay, filimka saliidda ee SN waa mid daciif ah. Midda saddexaad waa waxqabadka ilaalinta: Waxqabadka ilaalinta SP waa mid xooggan, waxqabadka ilaalinta SN waa mid guud.

Dhab ahaantii, inta badan milkiilayaasha baabuurta, saliidda SN waxay awood u leedahay inay la kulanto isticmaalka maalinlaha ah, saliidda N-grade waxay leedahay iska caabin wanaagsan oo oksaydh ah, awoodda xakamaynta wasakhda iyo xirashada shaqada ilaalinta, si loo hubiyo isticmaalka saliidda iyo waxqabadka joogtada ah.

Si kastaba ha ahaatee, haddii aad inta badan ku isticmaashid baabuurkaaga jawi magaalo oo aad u ciriiri ah, waxaad dooran kartaa saliid aad u horumarsan, taas oo noqon doonta mid aad u fiican deegaanka oo ka dhaqaale badan.


Milkiilayaasha la-hawlgalayaasha yaryar waxay dooran karaan si waafaqsan baabuurkooda safarka maalinlaha ah, ha si indho la'aan ah u dabagalin saliid heer sare ah, si aysan u sii wadin xoojinta shaqada dhululubo ee mashiinka gawaarida, kordhinta xiritaanka engine.

Ribang si buuxda saliid SP synthetic, baaruud hoose, fosfooraska hooseeya, dambas hooseeya iyo sulfate hooseeya, ilaalinta deegaanka iyo tamarta badbaadinta, anti-xidhka, joojin xawaaraha hoose ee gubasho hore LSPI, muujiyaan dhaqaalaha shidaalka, ilaalinta xidhashada silsiladda waqtiga, qiiqa hooseeya, sii ilaalin tayo leh dabinka qaybta matoorka!
