Lub zog tsav tsheb rau kev txhim kho piston nplhaib thev naus laus zis los ntawm ob yam: Ua ntej, kev txhim kho tag nrho lub tshuab txhawb kev nce qib ntawm piston nplhaib thev naus laus zis. Raws li kev tshawb fawb ywj pheej thiab kev txhim kho qib ntawm tag nrho lub tshuab txhim kho, piston nplhaib thev naus laus zis kuj tseem yuav txhim kho. Thib ob, piston nplhaib tuam txhab lag luam coj txoj hauv kev ntawm high-end technology thiab nquag txhawb kev siv cov thev naus laus zis tshiab kom ua tiav cov tshuab. Kev txhim kho thev naus laus zis ntawm kev lag luam piston nplhaib nyob rau xyoo tas los no yog ua kom cov khoom siv hlau, lub nplhaib piston thinner, thiab kev kho saum npoo yog high-end.

Tuam Tshoj cov thev naus laus zis tshiab rau piston rings tseem nyob rau theem tshawb nrhiav. Txawm hais tias ntau yam thev naus laus zis lawv tus kheej paub tab, ntau qhov kev tshawb fawb thiab kev sim yuav tsum tau siv rau hauv cov nplhaib piston. Ntau yam thev naus laus zis tshiab muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab qhov tseem ceeb yog los daws cov teeb meem zoo. Piston nplhaib tuam txhab uas muag cia siab rau cov kev taw qhia ntawm txawv teb chaws technology los txhim kho lawv cov kev kawm theem.

Txij li thaum lub nplhaib piston tsis yog tsuas yog ib qho tseem ceeb ntawm lub cav, tab sis kuj yog ib qho ntawm cov kev sib txhuam hnyav hauv lub cav, lub nplhaib piston yuav tsum muaj cov melting siab thiab hnav tsis kam. Nrhiav cov ntaub ntawv tshiab thiab cov txheej txheem kho saum npoo tshiab tau dhau los ua lub ntsiab lus tseem ceeb ntawm kev lag luam piston nplhaib kom tau raws li kev xav tau ntawm kev lag luam yav tom ntej. Cov piston rings ntawm cov tsoos automotive diesel xyaw feem ntau siv cov hlau ductile thiab alloy cam khwb cia hlau, thiab piston rings ntawm roj av cav feem ntau siv hlau.

Vim yog kev txhim kho ntawm cov cav tsheb nyob rau hauv cov kev taw qhia ntawm lub zog siab, siab tso zis thiab lub teeb yuag, piston rings ua nyias thiab sib dua, uas yuav tsum tau piston rings kom muaj zog. Yav dhau los, steel piston rings uas feem ntau siv rau hauv cov roj av cav tau maj mam qhia Hauv cov tshuab hluav taws xob, qee lub cav diesel pib siv cov roj roj steel. Piv nrog cam khwb cia hlau rings, steel piston rings yuav tsum tsis muaj txheej txheem casting, yog lub teeb hauv qhov hnyav, thiab muaj txoj kev ua haujlwm yooj yim. Mainstream manufacturers tau nqis peev nyob rau hauv txoj kev loj hlob thiab zus tau tej cov steel rings tshiab. Qhov kev faib ua feem ntawm steel rings siv nyob rau hauv automotive diesel cav kev lag luam kuj siab heev.

Kev nce hauv piston nplhaib xa tawm yog qhov laj thawj tseem ceeb rau kev nce hauv piston nplhaib muag. Vim Tuam Tshoj lub peev xwm ntau lawm ntawm piston rings thiab cov khoom lag luam qis, ntau lub tuam txhab nyob rau sab hnub tuaj Asia, Middle East, Africa, Russia thiab lwm lub teb chaws thiab cheeb tsam tau nyiam ntau lub tuam txhab mus yuav hauv Suav teb. Tsis tas li ntawd, cov tuam txhab lag luam los ntawm Tebchaws Europe, Tebchaws Meskas, Nyiv, Kaus Lim Qab Teb thiab lwm lub tebchaws siv Tuam Tshoj cov neeg ua haujlwm pheej yig los hloov cov khoom siv qis-thiab nruab nrab-kawg piston rings mus rau Tuam Tshoj. Qhov no tau coj txoj hauv kev loj hlob tsis tau pom dua rau Suav piston nplhaib tuam txhab.
