Sida loo go'aamiyo saamiga cadaadiska
Haddii aad dhisayso matoor cusub oo aad u baahan tahay mitir, ama aad xiisaynayso sida shidaalka baabuurkaaga u shaqeeyo, waa in aad xisaabin kartaa saamiga injiinka. Waxaa jira isla'egyo dhowr ah oo loo baahan yahay si loo xisaabiyo saamiga cadaadiska haddii aad gacanta ku samaynayso. Waxa laga yaabaa inay u muuqdaan kuwo adag marka hore, laakiin runtii waa joomatari aasaasiga ah.
Saamiga isku xidhka matoorku waxa uu cabbiraa laba shay: saamiga xadiga gaasta ku jira dhululubo marka pistonku uu ku yaal xaga sare ee istaroogga (Xarunta dhimatay ee sare, ama TDC), marka la barbar dhigo cadadka gaaska marka pistonku uu gunta joogo . istaroog (xarunta dhimatay ee hoose, ama BDC). Si fudud loo dhigo, saamiga cadaadisku waa saamiga gaaska la tuujiyey iyo gaasta aan la adkeyn, ama sida adag ee isku dhafka hawada iyo gaaska loogu dhejiyo qolka gubanaya ka hor inta aan la shidin dhinbiilka. Kolka uu cufan yahay isku-dhafkan, ayaa si fiican u gubta, tamar badana waxa loo beddelaa awoodda mishiinka.
Waxaa jira laba hab oo aad isticmaali karto si aad u xisaabiso saamiga isku xidhka ee mishiinka. Midka koowaad waa nooca gacanta, kaas oo u baahan in aad dhammaan xisaabta u samayso sida ugu macquulsan, iyo kan labaad-iyo malaha kan ugu badan-waxa uu u baahan yahay cabbirka cadaadiska in la geliyo kartoon dhimbiil oo madhan.
Habka 1 ee 2: Gacan ku cabbir saamiga isku ururinta
Habkani wuxuu u baahan yahay cabbirro sax ah, sidaas darteed waa muhiim inaad haysato qalab aad u sax ah, matoor nadiif ah, iyo labanlaab ama saddex laab ah hubi shaqadaada. Habkani wuxuu ku habboon yahay kuwa dhisaya mishiinka oo haysta qalabka gacanta, ama kuwa hore u lahaa mishiinka. Si loo isticmaalo habkan, waxay qaadan doontaa wakhti aad u dheer in la kala furfuro mishiinka. Haddii aad leedahay matoor la isku shiday, hoos u rog oo isticmaal habka 2 ee 2.
Alaabta loo baahan yahay
- Nutrometer
- Xisaabiye
- Dereaser iyo calal nadiif ah (haddii loo baahdo)
- Buugga soo saaraha (ama buug-gacmeedka milkiilaha baabuurka)
- mikromitir
- Qoraal, qalin iyo warqad
- mastarada ama cabirka cajalad (waa in ay ahaataa mid aad sax u ah millimitirka)
Tallaabada 1: Nadiifi mishiinka Si fiican ugu nadiifi dhululubada matoorka iyo biistoonada qalabka-dejiya iyo marada nadiifka ah.
Tallaabada 2: Soo hel cabbirka daloolka. Qiyaasta daloosha oo miisaan leh ayaa loo isticmaalaa in lagu cabbiro dhexroorka daloolka ama, xaaladdan, dhululubo. Marka hore go'aami dhexroorka qiyaastii ee dhululubada oo ku qiyaas cabbirka birta adoo isticmaalaya micrometer. Geli cabbirka cadaadiska dhululubada oo cabbir dhexroorka dalool dhowr jeer meelo kala duwan oo gudaha dhululubada oo qor cabbirrada. Isku-dar cabbiradaada oo u qaybi inta aad qaadatay (badanaa saddex ama afar ayaa ku filan) si aad u hesho dhexroorka celceliska. U qaybi cabbirkan 2 si aad u hesho dhexroorka daloolka celceliska.
Tallaabada 3: Xisaabi cabbirka dhululubada. Adigoo isticmaalaya mastarad sax ah ama cabirka cajalad, cabbir dhererka dhululubada. Hoos ka cabbir ilaa halka ugu sarreysa, adigoo hubinaya in talisku toosan yahay. Tiradani waxay xisaabinaysaa istaroogga, ama aagga, in pistonku kor ama hoos ugu dhaqaaqo hal mar. Isticmaal qaaciidadan si aad u xisaabiso mugga dhululubada: V = π r2 h
Talaabada 4: Go'aami xajmiga qolka gubashada. Ka hel mugga qolka gubashada ee buug-gacmeedka mulkiilaha gaadhigaaga. Mugga qolka gubashada waxaa lagu cabbiraa sentimitir cubic (CC) waxayna muujineysaa inta walaxda loo baahan yahay si loo buuxiyo furitaanka qolka gubta. Haddii aad dhisayso mishiin, tixraac buug-gacmeedka wax-soo-saarka. Haddii kale, tixraac buug-gacmeedka mulkiilaha baabuurka.
Tallaabada 5: Soo hel Dhererka Isku-buufiska ee Piston. Ka hel dhererka isku-buufinta ee bistanka buug-gacmeedka. Cabbirkani waa masaafada u dhaxaysa dhexda daloolka biinanka iyo sare ee piston.
Tallaabada 6: Cabbir mugga biistaanka. Mar labaad buug-gacmeedka, ka hel mugga qubbada ama madaxa piston, oo sidoo kale lagu qiyaasay sentimitir cubic. Bisitoonka leh qiimaha CC ee togan waxaa had iyo jeer loo yaqaan "dome" oo ka sarreeya dhererka cadaadiska ee piston, halka "poppet" uu yahay qiime taban oo lagu xisaabtamo jeebabka waalka. Caadi ahaan bistoonku waxa uu leeyahay qubbad iyo qubbad labadaba, mugga ugu dambeeyana waa wadarta labada hawlood (dome minus poppet).
Tallaabada 7: Soo hel farqiga u dhexeeya bistoonka iyo sagxada. Xisaabi cadadka nadiifinta inta u dhaxaysa bistoonka iyo sagxada adoo isticmaalaya xisaabinta soo socota: (Bore [cabbirka tilaabada 2] + Dhexroorka bore × 0.7854 [joogta ah oo wax walba u beddesha cubic inches] × masaafada u dhaxaysa bistoonka iyo sagxada sare ee xarunta dhintay [TDC] ).
Talaabada 8: Go'aami mugga suufka. Cabbir dhumucda iyo dhexroorka gaaska madaxa dhululubada si loo go'aamiyo mugga gaaska. Sidan u samee si la mid ah sidii aad u samaysay farqiga sagxada (tallaabada 7): (daloolka [cabbirka tilaabada 8] + dhexroor daloolka × 0.7854 × dhumucda gaaska).
Talaabada 9: Xisaabi saamiga cadaadiska. Xisaabi saamiga isku-buufinta adoo xallinaya isla'egtan:
Haddii aad hesho nambar, dheh 8.75, saamiga cadaadisku wuxuu noqonayaa 8.75:1.
- FunctionsJ: Haddii aadan rabin inaad xisaabiso nambarada laftaadu, waxaa jira dhawr xisaabiye oo saamiga online ka ah oo adiga kuu shaqayn doona; Riix halkan
Habka 2 ee 2: isticmaal cabbirka cadaadiska
Habkani wuxuu u fiican yahay kuwa leh matoor la dhisay oo raba inay ka hubiyaan cadaadiska baabuurka iyada oo loo marayo dhinbiyadaha. Waxaad u baahan doontaa caawimada saaxiib.
Alaabta loo baahan yahay
- qiyaasta cadaadiska
- Spark plug wrench
- Gacan-gashiyada shaqada
Tallaabada 1: Diiri mishiinka. Ku wad mishiinka ilaa uu ka kululaado heerkulka caadiga ah. Ma doonaysid inaad tan samayso marka mishiinku qabow yahay sababtoo ah ma heli doontid akhris sax ah.
Talaabada 2: Ka saar dhinbiilayaasha. Gabi ahaanba dami dabka oo ka saar mid ka mid ah dhinbilayaasha fiilada ku xidhaysa qaybiyaha. Ka saar dhimbiilka.
- Functions Haddii dhinbiilayaashu ay wasakh yihiin, waxaad tan u isticmaali kartaa fursad aad ku nadiifiso.
Tallaabada 3: Geli cabbirka cadaadiska. Geli caarada cabbirka cadaadiska godka ay ku dheggan tahay dhimbiilku. Waa muhiim in sanbabada si buuxda loo geliyo qolka.
Tallaabada 4: Hubi dhululubada. Inta aad cabbirka hayso, saaxiib matoorka daabulo oo deddeji baabuurka ilaa shan ilbiriqsi si aad u hesho akhriska saxda ah. Xir mishiinka, ka saar caarada cabbirka oo dib ugu rakib balaastigga oo leh qulqulka saxda ah sida buug-gacmeedka lagu faray. Ku celi tillaabooyinkan ilaa aad tijaabiso dhululubo kasta.
Tallaabada 5: Samee tijaabada cadaadiska. Dhululubo kasta waa inuu lahaadaa cadaadis isku mid ah waana inuu la mid yahay lambarka buug-gacmeedka.
Talaabada 6: Xisaabi PSI ilaa Saamiga Cadaadiska. Xisaabi saamiga PSI iyo saamiga cadaadisku. Tusaale ahaan, haddii aad leedahay akhriska cabbirka qiyaastii 15 iyo saamiga cadaadisku waa inuu noqdaa 10: 1, markaa PSI-gaagu waa inuu noqdaa 150, ama 15x10/1.
