Isandulelo: I-cylinder liner iyingxenye yenhliziyo yenjini. Indawo yayo engaphakathi, kanye nengaphezulu lepiston, iringi yepiston, kanye nendawo engaphansi yekhanda le-cylinder, bakha igumbi elivuthayo lenjini, futhi liqondisa ukunyakaza okuhambisanayo kwepiston. Ingaphakathi le-cylinder liyindawo yomhlangano kanye nendawo yokusebenza, futhi ikhwalithi yokucubungula kwayo ithinta ngokuqondile ukusebenza komhlangano nokusebenza kwesevisi yenjini.
Ngaphambi kukaFebhuwari 2008, lezi zinkinga ezilandelayo bezikhona kumasilinda enjini yasolwandle yaseChina:
① Izinga lokucubungula lemboni yasekhaya yaseShayina liphansi, udonga lwangaphakathi lwe-cylinder liner lwenziwe nge-honing mesh evamile, umphumela wokuthambisa kanye nokunciphisa ukungqubuzana mubi, impilo yesevisi ye-cylinder liner ifushane, ukusetshenziswa kwamandla kwenjini kuphezulu. , futhi ukukhishwa kudlula izinga;
②Izinga lokushisa elisebenzayo legumbi lomlilo lingaphezulu kuka-1000 ℃ phakathi nenqubo yokusebenza kwenjini, futhi ukuguga kwe-fusing kulula kakhulu ukukhiqiza amadiphozithi ekhabhoni, okuholela ekugugekeni kwe-abrasive. Yehlisa izindleko zokunakekela ulayini we-cylinder engine cylinder obiza kakhulu;
③ Ngaphambi kukaFebhuwari 2008, iningi lama-cylinder liners ezinjini zasolwandle zazenziwe ngensimbi ephezulu ye-phosphorus cast, i-boron cast iron, i-vanadium titanium cast iron, i-low alloy cast iron, njll. izici ezibanzi zemishini yezinto Amandla aphansi nobulukhuni, ukumelana nokugqokwa okubi, impilo emfushane yomkhiqizo, okunzima ukuhlangabezana nezidingo zezinjini zasolwandle; Ukusebenza kahle, ukunemba okuphezulu nokudlidliza okuphansi, okokusebenza kwe-cylinder liner ngaphambi kukaFebruwari 2008 akukwazi ukuhlangabezana ngokugcwele nezimfuneko.
izinhlobo ezimbili ze-marine liner: i-liner eyomile kanye ne-liner emanzi
1. I-cylinder liner eyomile isho ukuthi ingaphezulu le-cylinder liner alithinti into yokupholisa. Ukuze uqinisekise umphumela wokukhipha ukushisa kanye nokuma kwe-cylinder liner, futhi uthole indawo eyanele yokuxhumana ne-cylinder block, ingaphezulu le-cylinder liner eyomile kanye nezindawo zangaphakathi nezingaphandle zembobo ye-cylinder block ehambisana nayo. babe nokunemba okuphezulu kwemishini. Amasilinda omile anezindonga ezincane kanti amanye awugqinsi ngo-1mm kuphela. Ingxenye engezansi yendilinga yangaphandle ye-cylinder liner eyomile ine-engeli encane ye-taper ukucindezela ibhulokhi yesilinda. Ingaphezulu le-liner eyomile (noma phansi kwe-cylinder bore) itholakala noma ngaphandle kwama-flanges. I-Flanged inokuphazanyiswa okuncane ngoba i-flange iyasiza ekumeni kwayo.
Izinzuzo ze-cylinder liner eyomile ukuthi akulula ukuvuza, ukuqina kwesakhiwo se-cylinder kukhulu, isisindo somzimba sincane, akukho cavitation, futhi ibanga phakathi kwezikhungo ze-cylinder lincane; amaphutha akulula ukulungisa nokushintshwa, kanye nokungashisi kahle ukushisa. Ezinjinini ezinobubanzi obungaphansi kuka-120mm, isetshenziswa kakhulu ngenxa yomthwalo wayo omncane oshisayo. Abakhiqizi be-cylinder air compressor cylinder liner abangenawo uwoyela bakholelwa ukuthi kufanelekile ukusho ukuthi umugqa omile wamasilinda wezinjini zikadizili zezimoto zakwamanye amazwe ukhula ngokushesha.
2. Ingaphezulu le-cylinder liner emanzi lithintana ngqo nesipholile, futhi ugqinsi lwaso lodonga lushubile kunalolo lwe-cylinder liner eyomile. Ukuma kwe-radial kwe-cylinder liner emanzi ngokuvamile kuncike kumabhande amabili angaphezulu naphansi aphumayo aphumayo asebenzisana negebe eliphakathi kwebhulokhi yesilinda, futhi ukuma kwe-axial ukusebenzisa indiza engezansi ye-flange engaphezulu. Ingxenye engezansi ye-cylinder liner ivalwe ngezindandatho zokuvala zenjoloba ezi-1 kuya kwezi-3 ezikwazi ukumelana nokushisa futhi zimelana nowoyela. Ngokukhula kwezinga lokuqiniswa kwezinjini zikadizili, ukuvuleka kwama-cylinder liners okumanzi sekuyinkinga evelele, ngakho-ke amanye amacylinder enjini kadizili anezindandatho ezintathu zokuvala, kanti ingxenye engaphezulu yeyokugcina ixhumene nesipholile, esingaba khona. akugcini nje ukugwema ukugqwala kwendawo yokusebenza, Kulula ukuqaqa nokuhlanganisa, futhi ingakwazi ukumunca ukudlidliza futhi inciphise i-cavitation. Ezinye ezimbili ezingenhla nezimaphakathi zenziwe ngerabha yokwenziwa ye-ethylene-propylene ukuze ivale into epholile; ephansi yenziwe nge-silicone impahla yokuvala uwoyela, futhi lezi ezimbili azikwazi ukufakwa okungalungile. Abanye baphinde bafake indandatho yokuvala kusilinda ukuze kuthuthukiswe ukuqina kwe-cylinder liner. Ingxenye engenhla ye-cylinder liner ngokuvamile ivalwe ishidi lensimbi endizeni engezansi ye-flange (ithusi noma i-aluminium gasket, i-aluminium gasket isetshenziselwa umzimba we-aluminium alloy cylinder, i-gasket yethusi ayivunyelwe ukugwema ukugqwala kwe-electrochemical).
