Injector Naafto Cusub oo Tayo Sare leh 295900-0280 295900-0210 Cirbadka Tareenka Caadiga ah ee Matoorka Denso

Cavitation Gudaha Cadaadiska Sare ee Tooska ah ee Daah-furnaanta Shidaalka Dhuumaha (QAYBTA 2)

Neefsashada mudista indhaha ee la heli karo (OA) ayaa loo adeegsaday dhowr daraasadood oo hore oo ku saabsan qulqulka gudaha ee joomatariyada buka muddada ah ee laga helay matoorada isku-duridda tooska ah.Qaar badan oo ka mid ah daraasaddan hore ayaa lagu sameeyay cadaadiska cirbadeynta oo aad uga hooseeya kuwa duritaanka warshadaha ee la xidhiidha, sababtoo ah caqabadda naqshadaynta durida OA oo u adkeysan karta cadaadiska sare ee duridda.Si loo magdhabo, qaar ayaa isticmaalay joomatari-kor loo qaaday si ay u dhigmaan lambarka Reynolds.

Daraasadaha isku dayay in ay gaaraan cadaadiska duritaanka dhabta ah ayaa halkan lagu soo koobi doonaa, maadaama kuwani yihiin kuwa ugu khuseeya naqshadda lagu soo bandhigay warqadan, ugu dambeyntiina waa kuwa ugu saxsan marka ay timaado soo saarida socodka xiisaha.

Arcoumanis iyo al.baadhay saamaynta joomateri-ka-qabashada iyadoo la barbardhigayo nambarada Reynolds iyo Cavitation ee cabbirka dhabta ah iyo kor loo qaaday joomatari[2].Waxay ogaadeen in qaababka cavitation-ku ay ku kala duwan yihiin labada joomatari ee nambarada cavitation ee isku midka ah.Labada miisaan ee joomatari waxay muujiyeen dalool joomatari dhinaca hoose ee cidhifka sare ee cidhifka sare (oo leh cirbaduhu hoos u tilmaamayo), iyo dalool xadhkaha ah oo ka jira dhinaca ka soo horjeeda daloolka kore.

Farqiga ugu weyn ee ay arkeen qorayaashu waxaa loo aaneynayaa kala duwanaanshaha waqtiga degenaanshaha xumbo ee qulqulka iyadoo ay ugu wacan tahay dhererka daboolka ee kala duwan.Injector-ka baaxadda weyn waxa uu ka samaysan yahay galaas akrilik ah, halka mudiyeha miisaanka dhabta ah uu ka samaysan yahay ul quartz ah oo ku dheggan jir mudista tareenka caadiga ah ee Bosch oo ay ku hareeraysan yihiin gallery taageero akrilik ah.Qaybta akriliga ah ayaa si weyn uga weyneyd birta asalka ah ee duriyaha.Reid iyo al.loo isticmaalo sapphire si uu u abuuro nooc la fududeeyay ee joomatari ee laga helay mudiyeyaasha valve-covered-orifice (VCO)[3].Waxay ku guuleysteen cadaadiska duritaanka ee 2000 bar oo leh naqshadeynta.Waxay u muuqataa in cirifka lagu dhisay lakabyo sapphire ah oo ku yaal jihada axial oo leh godadka taxane ah kuwaas oo sameeyay joomatari ugu dambeeya.Tani waxay ahayd hab xariif ah oo lagu fududaynayo habaynta qaybaha.
