piav qhia

Pistons yog reciprocating qhov chaw hauv lub cav lub tog raj kheej thaiv.Cov qauv tsim ntawm lub piston tuaj yeem muab faib ua sab saum toj, lub taub hau thiab tiab.Sab saum toj ntawm lub piston yog qhov tseem ceeb ntawm lub combustion chamber, thiab nws cov duab muaj feem xyuam rau cov xaiv combustion chamber daim ntawv.Feem ntau muaj ntau yam pits nyob rau sab saum toj ntawm lub cav diesel piston, thiab lawv cov duab tshwj xeeb, qhov chaw thiab qhov loj me yuav tsum tau yoog raws li qhov yuav tsum tau ua ntawm diesel cav tov tsim thiab combustion.
Lub luag haujlwm tseem ceeb ntawm lub piston yog tiv thaiv kev sib tsoo ntawm lub tog raj kheej, uas tau xa mus rau lub crankshaft los ntawm tus pin piston thiab lub piston.Tom qab ntawd, lub piston, lub tog raj kheej lub taub hau, thiab lub tog raj kheej phab ntsa tsim lub combustion chamber.
Piston rings muaj kev kho deg sib txawv vim lawv txoj haujlwm sib txawv.Sab nrauv ntawm thawj lub nplhaib piston feem ntau yog chrome-plated los yog txau nrog molybdenum, feem ntau los txhim kho lubrication thiab ua rau kom hnav tsis kam ntawm lub nplhaib piston.Feem ntau lwm cov piston rings yog tinned los yog phosphated, feem ntau los txhim kho hnav tsis kam.Yog tias lub nplhaib piston raug teeb tsa tsis raug lossis qhov kev sib khi tsis zoo, nws yuav ua rau cov roj ntawm lub tog raj kheej phab ntsa nce mus rau lub combustion chamber thiab hlawv nrog cov sib tov, ua rau cov roj hlawv.Yog tias qhov sib piv ntawm lub nplhaib piston thiab lub tog raj kheej phab ntsa me dhau los yog lub nplhaib piston tau daig hauv lub nplhaib zawj vim yog cov pa roj carbon deposits, thiab lwm yam, thaum lub piston reciprocates nce thiab nqis, lub tog raj kheej phab ntsa yuav raug khawb.Cov grooves sib sib zog nqus yog tsim rau ntawm phab ntsa, uas feem ntau hu ua qhov tshwm sim ntawm "lub tog raj kheej rub".Lub tog raj kheej phab ntsa muaj grooves thiab sealing tsis zoo, uas yuav ua rau cov roj hlawv.Yog li ntawd, kev ua haujlwm ntawm lub piston yuav tsum tau kuaj xyuas tsis tu ncua kom tsis txhob muaj qhov tshwm sim ntawm ob qho xwm txheej saum toj no thiab xyuas kom meej tias lub cav khiav hauv qhov zoo.
Kev xav tau
1. Nws yuav tsum muaj lub zog txaus, rigidity, me me thiab lub teeb yuag kom ntseeg tau qhov tsawg kawg nkaus inertial quab yuam.
2. Zoo thermal conductivity, kub tsis kam, siab tsis kam, corrosion kuj, txaus tshav kub dissipation peev, thiab me me cua sov cheeb tsam.
3. Yuav tsum muaj kev sib txhuam me me ntawm lub piston thiab phab ntsa piston.
4. Thaum qhov kub thiab txias hloov, qhov loj thiab cov duab hloov yuav tsum me me, thiab qhov tsawg kawg nkaus qhov sib txawv ntawm lub tog raj kheej phab ntsa thiab lub tog raj kheej phab ntsa yuav tsum tau khaws cia.
5. Lub coefficient ntawm thermal expansion yog me me, qhov tshwj xeeb lub ntiajteb txawj nqus yog me me, thiab nws muaj zoo hnav tsis kam thiab thermal zog.
