Sidee Shidaalka Iyo Saliida Naaftada Dhalinayaradu U Saxan Yihiin

Tilmaamaha matoorka naaftada waxay u baahan yihiin nadiif, naafto aan biyo lahayn, iyo maadada baaruuddu ku yar tahay.Guud ahaan, bS.2891: Shidaalka A1 ama A2, ama GB252 ama DIN/EN590, ASTMD975-88: 1-D iyo 2-D shidaalka naaftada caadiga ah, iyo darajada ku habboon iyadoo loo eegayo heerkulka goobta shaqada.Isticmaalka shidaalka waa in si adag loo xakameeyaa bilawga si loo hubiyo nadaafadda shidaalka, haddii mashruuca si fiican loo sameeyo, dayactirka matoorka qaaliga ah waa laga fogaan karaa.Ka hor inta aan saliidda ku jirta haanta lagu darin, waa in lagu daayaa 24 saacadood si loo xalliyo arrimaha shisheeye ee haanta.Ku nadiifi godka saliidda ee ku wareegsan foosto saliidda maro ka hor inta aanad furin daboolka daloolka saliidda.Qaybaha tuubada iyo matoorka gacanta ee la isticmaalo waa in lagu hayaa deegaan nadiif ah.

Doorashada saliidda saliidda (saliid)

Markaad qaboojinayso qalabka wax dhaliya, ku dar saliida saliidda digsiga saliidda mishiinka ilaa miisaanka ugu badan ee dipstick laga gaaro.Haddii ay jiraan tilmaamo gaar ah oo ku yaal daboolka haanta, fadlan halkan ku raac.Matoorada kala duwan waxay ku shaqeeyaan xaaladaha heerkulka kala duwan si ay u doortaan kooxda viscosity saliid sidoo kale waa ka duwan yahay, Shiinaha isticmaalaa kala soocida guud ee bulshada American guud ee Automotive Automotive (SEA) viscosity, kuwaas oo SEAJ300 soocidda viscosity engine.

W waxay u taagan tahay jiilaalka, macneheedu waa Jiilaal, miyir-qabka waxa loola jeedaa mawjadaha saliidda, ee ku habboon isticmaalka Jiilaalka, kala-saarku waxa uu leeyahay lix heerar viscosity saliidda jiilaalka (0W-25W) iyo afar kooxood oo viscosity saliid xagaaga (20-25).Viscosity firfircoon heerkulka hooseeya (Mpa.s, ie Milipaska · s), heerkulka ugu badan ee biyaha soo shubaya iyo viscosity ugu yar ee 100 ℃ ayaa loo baahan yahay heer kasta oo xadka saliid jiilaalka.Labada shuruudood ee heerkulka hoose ee viscosity firfircoon iyo heerkulka bamgareynta xadka ayaa ka tarjumaysa dhibka heerka viscosity saliidda si ay si guul leh u bilaabaan mishiinka oo ay galaan xaaladda caadiga ah ee jiilaalka, taas oo ah, dhibka bilaabista mishiinka heerkulka hooseeya 0W ilaa 25W si isdaba joog ah u kordha.Viscosity ugu yar ee kinematic ee 100 ℃ waxay ka tarjumaysaa uumiga luminta heerka viscosity jiilaalka heerkulka sare, taas oo ah, viscosity hoose macnaheedu waa luminta uumiga weyn;Isticmaalka saliidda oo sarreeya sababtoo ah luminta uumiga.Heerka viscosity saliidda xagaaga waxay u baahan tahay oo kaliya 100 ° C kala duwanaanshaha kinematic viscosity.Sidaa darteed, heerka viscosity laga bilaabo 0 ilaa barta 0 wuxuu kordhiyaa kororka viscosity, dhumucda filimka saliidda ee uu sameeyay dusha sare ee mishiinka ayaa kordha, taas oo kordhisa isticmaalka tamarta matoorka (isticmaalka saliidda), iyo hoos u dhac kasta oo heerka viscosity ah badbaadin ilaa 0.5% isticmaalka tamarta.

Darajooyinka viscosity saliidda xilliga qaboobaha iyo buundooyinka saliidda xagaaga ayaa la isku daray, sida 5W/30, 15W/40, iyo 20W/50.Saliida injiinka leh laba darajo viscosity waxaa loo yaqaan saliida marxaladaha badan, sida 15W/40 saliid, taas oo macnaheedu yahay in saliiddaani ay u dhiganto sharuudaha viscosity ee 15W saliid hal mar jiilaalka iyo SAE40 xagaaga.Saliid-kooxeedyo badan ayaa la isticmaali karaa jiilaalka iyo xagaaga labadaba;Waxaa loo isticmaali karaa labada qabow ee waqooyiga iyo koonfurta kulul, waxayna leedahay faa'iidooyinka kala duwanaanta heerkulka ballaaran iyo baaxadda baaxadda ballaaran.Waxa kale oo ay leedahay sifooyin badbaadinta tamarta.Marka la barbar dhigo saliidda hal mar (saliidda xagaaga), tan hore waxay badbaadin kartaa shidaalka 2-5% marka loo eego kan dambe.Saliida naaftada ee heerarka badan ayaa lagu caan baxay ilaa 50% Waqooyiga Ameerika iyo Galbeedka Yurub.Mustaqbalka, saamiga saliidda marxaladaha badan waa la kordhin doonaa waxayna u egtahay in ay noqoto mid hooseeya.Anaga dab-dhaliye , waxaanu ku talinaynaa in la isticmaalo 15W/40 Saliid inta badan dalka.

Guangxi Dingbo Wax-soo-saarka Qalabka Korontada Co., Ltd. oo la aasaasay 2006, waa soo-saare dhaliye naafto ah oo ku yaal Shiinaha, kaas oo isku dara naqshadeynta, sahayda, hawlgelinta iyo dayactirka qalabka dhaliya naaftada.Alaabtu waxay dabooshaa Cummins, Perkins, Volvo, Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai iwm oo leh awood koronto 20kw-3000kw, waxayna noqdaan warshadooda OEM iyo xarunta farsamada.
