Qhov sib txawv ntawm cov pob hluav taws xob zoo tib yam thiab cov platinum spark plugs muaj plaub qhov sib txawv ntawm cov pob hluav taws xob zoo tib yam thiab cov platinum spark plugs: 1. Cov khoom siv tsis siv 2. Cov kev pab cuam lub neej sib txawv 3. Tus nqi sib txawv 4. Qhov sib txawv yog txawv
1. Cov ntaub ntawv siv tsis yog
Cov khoom siv rau lub txim hluav taws xob zoo tib yam feem ntau yog npib tsib xee alloy, uas yog cov hlau uas muaj cov nickel ua lub hauv paus thiab lwm yam khoom.
Cov khoom siv hauv Perkin spark plugs yog platinum, ib txwm tshwm sim dawb muaj nuj nqis hlau.
2. Lub neej ua haujlwm txawv
Cov pob hluav taws xob feem ntau yuav tsum tau hloov txhua 30, 000 mais lossis ntau dua.
Perkin spark plugs kav ntev dua vim tias lawv muaj zog dua li cov pob hluav taws xob zoo tib yam.
3. Cov nqi sib txawv
Ordinary spark plugs yog ua los ntawm alloy, thiab tus nqi qis dua
Platinum spark plugs siv cov hlau tseem ceeb platinum, thiab tus nqi yog kaum ntawm yuan siab dua li cov hluav taws xob zoo tib yam.
4. Lub txim taws sib txawv
Qhov sib txawv ntawm cov pob hluav taws zoo tib yam tsuas yog 0 7-0.8mm.
Qhov sib txawv ntawm lub platinum spark plug yog 1.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm spark plug:
Lub rooj tsavxwm hluav taws xob ignites cov roj sib tov hauv lub tog raj kheej los ntawm kev rov ua dua thiab txuas ntxiv lub zog tsim hluav taws xob thiab ignition. Nyob rau lub sijhawm no, lwm qhov chaw ntawm qhov hluav taws xob hluav taws xob tsim lub sijhawm hluav taws xob hluav taws xob hluav taws xob los tsim cov hluav taws xob thiab tsim hluav taws xob tawg los muab lub zog xav tau rau lub tshuab hluav taws xob tso tawm.
Lub luag haujlwm ntawm lub tshuab hluav taws xob yog los qhia cov hluav taws xob hluav taws xob siab (ntau tshaj 10, 000 volts) tsim los ntawm cov hluav taws xob hluav taws xob rau hauv lub tog raj kheej lub cav, thiab tsim cov hluav taws xob nruab nrab ntawm qhov khoob ntawm lub qhov hluav taws xob hluav taws xob kom ignite lub sib tov. Qhov chaw ua haujlwm ntawm lub qhov hluav taws xob yog qhov hnyav heev. Siv lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob plaub-stroke zoo tib yam ua piv txwv. Thaum noj cov hlab ntsha, qhov kub tsuas yog 60 degree thiab lub siab yog 90KPa; Thaum nws yog ignited thiab hlawv, qhov kub yuav instantly nce mus rau 3000 degree thiab lub siab yuav ncav cuag 4000KPa; Qhov sib txawv ntawm cov cua txias thiab cua kub ceev yog qhov siab heev, uas tsis tuaj yeem ua haujlwm los ntawm cov khoom siv zoo tib yam, thiab kev ua haujlwm rwb thaiv tsev yuav tsum tau lav, yog li cov khoom siv ntawm lub txim hluav taws xob tseem nruj heev.
Lub txim hluav taws xob me me, thiab ob peb ntawm lawv tuaj yeem muab tso rau hauv ib lub hnab, tab sis nws cov qauv tsis yooj yim. Nws muaj ob ntu: ib qho insulator thiab lub plhaub hlau: lub plhaub hlau muaj xov rau screwing rau hauv lub tog raj kheej; lub insulator yog ntsia rau hauv lub plhaub, thiab ib tug nruab nrab electrode khiav los ntawm nws, thiab muaj ib tug hlau txiv ntseej nyob rau sab sauv kawg ntawm lub center electrode, uas yog kev cob cog rua los ntawm high-voltage nyob ntawm tej los ntawm lub tis board; av electrode yog welded nyob rau hauv qis kawg ntawm lub plhaub, thiab muaj qhov sib txawv ntawm 0 6-1 0 hli nruab nrab ntawm qhov nruab nrab electrode thiab hauv av electrode. Thaum cov hluav taws xob high-voltage dhau los ntawm qhov sib txawv no thiab nkag mus rau hauv av, sparks yuav tawg tawm thiab cov sib tov yuav ignited. .
Qhov tseem ceeb ntawm lub txim hluav taws xob yog lub insulator. Yog hais tias lub insulator tsis ua hauj lwm, lub high voltage yuav "mus ib tug me me txoj kev" es tsis txhob nkag mus rau hauv av los ntawm ob tug ncej, ua rau tsis muaj spark. Lub rwb thaiv tsev ntawm lub txim hluav taws xob yuav tsum muaj cov khoom siv zoo, muaj zog tiv taus, kub kub cuam tshuam, thiab tshuaj lom neeg corrosion kuj. Ordinary spark plugs feem ntau yog ua los ntawm alumina-based ceramics. Qhov luaj li cas ntawm lub txim hluav taws xob yog sib xws thoob plaws ntiaj teb, thiab nws tuaj yeem siv rau hauv txhua lub tsheb. Txawm li cas los xij, vim qhov sib txawv ntawm hom roj av cav, muaj ob hom kev siv hluav taws xob, hom txias thiab kub hom. Hom txias thiab hom kub yog cov ntsiab lus txheeb ze, uas cuam tshuam txog cov yam ntxwv thermal ntawm lub txim hluav taws xob. Lub tshuab hluav taws xob yuav tsum muaj qhov kub thiab txias kom ua haujlwm zoo, thiab tsis muaj cov pa roj carbon deposits ua haujlwm zoo. Kev xyaum tau ua pov thawj tias thaum lub qhov hluav taws xob ntsaws hluav taws xob khaws cia ntawm qhov kub ntawm 500-600 degree C, cov roj tee uas poob rau ntawm lub insulator tuaj yeem hlawv tam sim ntawd yam tsis muaj cov pa roj carbon deposits. Yog tias qhov ntsuas kub siab tshaj qhov ntsuas kub no, nws yuav kub hnyiab thaum ntxov, thiab yog tias qhov ntsuas kub qis dua qhov ntsuas kub no, yuav muaj cov pa roj carbon deposits. Qhov kub ntawm cov cav sib txawv yuav txawv, thiab tus tsim qauv siv qhov ntev ntawm lub tsho insulator los daws qhov tsis sib xws. Qee cov tiab luv luv thiab muaj qhov cua sov me me thiab cov cua sov sai sai, yog li qhov kub ntawm daim tiab qis dua. Lawv yog hu ua txias spark plugs, uas yog haum rau high-power engine nrog kev kub ceev thiab siab compression piv; Qhov kub siab dua, nws yog hu ua lub pob hluav taws kub kub, uas yog tsim rau cov tshuab hluav taws xob qis nrog qhov nruab nrab thiab qis qis thiab qis compression ratios. Lub txim hluav taws xob siv li cas hauv koj lub tsheb yuav tsum raug xaiv raws li cov chaw tsim khoom tsim qauv, tsis yog txhua lub txim hluav taws xob tsim nyog.
