Waa maxay shidaalka iyo saliidaha

Sida laga soo xigtay warar aan la xaqiijin, saliidaha loo isticmaalo by nin muddo ka badan 6 kun. Years ka hor. Oil ayaa loo yaqaan muddo dheer, laakiin in la isticmaalo in ay foomka saafi ah waa la soo dhaafay, laakiin processing hadalka oo aan tago. Marka dadka bartay in ay ka arrinsashada, ka dibna waxaan ku soo gaaray la shito oo kaliya, sida ugu qiimaha badan ah - saliid - isticmaalaa sida shidaalka, ama si fudud lagu gubay. Oo ilaa 90% waa miisaan saliidda aasaasiga ah.

Laakiin technology aan weli taagan - oo hadda in warshado sifeeya saliidda ay barteen in ay kala saliidda ku shubaa jajabyada kala duwan. daaweynta Xiga koreen oo saliid qiimo ka, ka dibna loo yaqaan saliid ama macdanta. In matoorada casriga ah ee baabuurta - load sare kulaylka farsamo, si saliidaha, waayo, iyaga waa in ay buuxiyaan shuruudaha qaarkood.

Si loo hagaajiyo tayada iyo saliidda lagu cabbeeyo adigoo isticmaalaya dheer ku darina walxaha gaar ah (lagu daro). Mid kasta oo ka daro, kuwaas oo hagaajinaysaa indices on hal ama dhowr dhibcood. Tusaale ahaan, daro protivoiznosostoykie ku daray in ay saliidaha si loo yareeyo heerka Duugga ah qaybo ka shaqeeya, iyo nadiifinta - yareeyo xaddiga dhigaalka iyo ilaalinta qalab giraanta ku nqoday. saliidaha cabbeeyo Modern tirin karaa in ka badan toban sano ah oo kordhay.

Iyada oo tiro balaadhan oo ah lagu daro iyo suurtagalnimada in ay iyaga geeyo iyo in la kordhiyo kala duwan, kuwaas oo bixiya saarayaasha. Tani cabbeeyo saliidaha, taas oo ay soo saaraan. Oo ka sokow, waxaa kaloo jiray dhowr ka mid ah noocyada diirada ay - engine, gudbinta iyo kale. Ka hor inta iibsiga saliidaha cabbeeyo (xitaa soo saaraha si fiican u yaqaan) u baahan tahay in la ogaado mabaadi'da aasaasiga ah ee ay doortaan.

Saliidaha leeyihiin oo xuduudaheedu badan ku qeexan sifooyinka farsamo, laakiin gadashada waxaa lagama maarmaan ah in ay bixiyaan oo kaliya in labada iyaga ka mid ah dareenka. Heerka tayada saliid muujinaysaa waafaqid ee gaariga la wax this, iyo ku nafwaayay ah - ay ku habboon in loo isticmaalo cimilada gaar ah iyo xilli.

Si aad u go'aansato in in uu yahay jilciyaha caawin doonaa calaamad joogo on fasalka kasta oo ganacsi, iyadoo nidaamka tusmaynta caalamka ka mid ah. technology tilmaamay Heerarka dibada iyo tafaasiirta ku qeexan index nafwaayay sida uu qaabka uu isku raacay Society American ee Automotive Injineerro SAE, sidaas qiyaasay in ku nafwaayay ah la sheegi doonaa ka dib markii sixitaanka warqado SAE. Muujinaysaa by warqadda W fasalada jiilaalka ee shidaalka iyo saliidaha, iyo xagaaga - tilmaan fudud ku nafwaayay ah.

Sidoo kale waxaa jira qormo caadiga ah. Tusaale ahaan, hoos naqshada SAE J300 qarinaya lix fasal ee hab qaboobaha nafwaayay - 0W, 5W, 10W, 15W, 20W, 25W. Dhammaan casharada, kuwaas oo loogu ballan qaaday inuu ku soo bilowdo mishiinka in xaaladda qabow, iyo dhaqdhaqaaqa shidaalka iyo saliidaha qaadataa meel si xor ah oo dhan nidaamka kala duwan heerkulka a -30- + 5 digrii. noocyo Summer aadan haysan warqado dheeraad ah ee sixitaanka, laakiin la kordhiyo ku nafwaayay ee kala duwan, kuwaas oo u kala qaybsan yihiin fasalo ah SAE 20, 30, 40, 50, 60.

Haddaba si aad u ogaataan waxa ay tahay shidaalka iyo saliidaha, iyo waxa ay kala soocidda!
