Intshayelelo: I-cylinder liner yinxalenye yentliziyo ye-injini. Umphezulu wayo ongaphakathi, kunye nomphezulu wepiston, umsesane wepiston, kunye nomgangatho ophantsi wentloko yesilinda, zenza igumbi lokutsha le-injini, kwaye ukhokele ukuphindaphinda kwentshukumo yepiston. Umgangatho wangaphakathi we-cylinder uyindawo yokudibanisa kunye nomgangatho osebenzayo, kwaye umgangatho wokulungiswa kwayo uchaphazela ngokuthe ngqo ukusebenza kwendibano kunye nokusebenza kwenkonzo ye-injini.
Ngaphambi kukaFebruwari ka-2008, ezi ngxaki zilandelayo zazikhona kwii-cylinder cylinder injini zaselwandle zaseTshayina:
① Inqanaba lokucutshungulwa kweshishini lasekhaya laseTshayina liphantsi, udonga lwangaphakathi lwe-cylinder liner lwenziwe ngomnatha oqhelekileyo we-honing, i-lubrication kunye nefuthe lokunciphisa i-friction libi, ubomi benkonzo ye-cylinder liner bufutshane, ukusetyenziswa kwamandla e-injini kuphezulu. , kwaye ukukhutshwa kudlula umgangatho;
②Iqondo lokushisa elisebenzayo legumbi lokutsha lingaphezulu kwe-1000 ℃ ngexesha lenkqubo yokusebenza kwe-injini, kwaye i-fusing wear ilula kakhulu ukuvelisa iidiphozithi zekhabhoni, okubangela ukuguga kwe-abrasive. Inciphisa iindleko zokugcinwa kwe-liner ye-injini ye-injini yaselwandle ebiza kakhulu;
③ Phambi kukaFebruwari ka-2008, uninzi lwee-cylinder liner zeenjini zaselwandle zazenziwe ngentsimbi ephezulu yephosphorus cast, iboron cast iron, vanadium titanium cast iron, low alloy cast iron, njl.njl. iipropathi ezibanzi zoomatshini bezinto Amandla aphantsi kunye nobunzima, ukunganyangeki kokunxiba, ubomi obufutshane bemveliso, kunzima ukuhlangabezana neemfuno zeenjini zaselwandle; Ukusebenza kakuhle, ukuchaneka okuphezulu kunye nokungcangcazela okuphantsi, izinto ezikhoyo ze-cylinder liner ngaphambi koFebruwari 2008 azikwazi ukuhlangabezana ngokupheleleyo neemfuno.
iintlobo ezimbini ze-marine liner: i-liner eyomileyo kunye ne-liner emanzi
1. I-cylinder liner eyomileyo ithetha ukuba umphezulu we-cylinder liner awuchukumisi into yokupholisa. Ukuze kuqinisekiswe impembelelo yokutshatyalaliswa kobushushu kunye nokubeka i-cylinder liner, kwaye ufumane indawo yokudibanisa eyaneleyo kunye nebhloko ye-cylinder, umphezulu we-cylinder liner eyomileyo kunye nemigangatho yangaphakathi nangaphandle ye-cylinder block ye-hole ehambelana nayo. ube nokuchaneka okuphezulu komatshini. Ii-cylinder liners ezomileyo zineendonga ezibhityileyo kwaye ezinye zinobukhulu obuyi-1mm kuphela. Isiphelo esisezantsi sesangqa sangaphandle se-cylinder liner eyomileyo sine-angle encinci ye-taper yokucinezela ibhloko ye-cylinder. Umphezulu we-liner eyomileyo (okanye i-bottom of the cylinder bore) ifumaneka kunye okanye ngaphandle kweeflange. I-Flanged inokuphazamiseka okuncinci kuba i-flange inceda ekumiseni kwayo.
Iingenelo ze-cylinder liner ezomileyo kukuba akulula ukuvuza, ukuqina kwesakhiwo se-cylinder sikhulu, ubunzima bomzimba buncinci, akukho cavitation, kwaye umgama phakathi kwamaziko e-cylinder uncinci; iziphene azilunganga ukulungisa kunye nokubuyisela, kunye nokuchithwa kobushushu obubi. Kwii-injini ezinobubanzi obungaphantsi kwe-120mm, isetyenziswa ngokubanzi ngenxa yomthwalo wayo omncinci we-thermal. Abavelisi be-oil-free air compressor cylinder liner bakholelwa ukuba kuyafaneleka ukukhankanya ukuba i-cylinder liner eyomileyo yeenjini ze-diesel zangaphandle zikhula ngokukhawuleza.
2. Umphezulu womgca we-cylinder omanzi udibana ngokuthe ngqo ne-coolant, kwaye ubukhulu bayo bodonga bukhulu kunobo be-cylinder liner eyomileyo. Ukubekwa kwe-radial ye-liner ye-cylinder emanzi ngokubanzi kuxhomekeke kumabhanti amabini aphezulu kunye asezantsi aphumayo aphumayo asebenzisana nomsantsa phakathi kwebhloko ye-cylinder, kwaye indawo ye-axial kukusebenzisa indiza engezantsi ye-flange ephezulu. Inxalenye engezantsi ye-cylinder liner ivalwe nge-1 ukuya kwi-3 yokumelana nokushisa kunye ne-oyile-resistant-resistant rubber rings. Ngokunyuka kweqondo lokomelezwa kweenjini zedizili, ukutyhoboza kwee-cylinder liners ezimanzi kuye kwaba yingxaki ebalaseleyo, ngoko ke ezinye ii-cylinder ze-injini zedizili zineringi zokutywina ezintathu, kwaye indawo engasentla yeyokugqibela inxibelelana nesipholisi, esikwaziyo. akugcini nje ukuphepha ukugqwala kwendawo esebenzayo, Kulula ukuqhaqha kunye nokudibanisa, kwaye inokufunxa i-vibration kunye nokunciphisa i-cavitation. Ezinye ezimbini eziphezulu neziphakathi zenziwe ngerabha yokwenziwa ye-ethylene-propylene ukutywina into epholileyo; eyona iphantsi yenziwe ngezinto ze-silicone ukutywina ioli, kwaye ezimbini azikwazi ukufakwa ngokungalunganga. Abanye bafaka ikhonkco lokutywina kwi-cylinder ukuphucula ukuqina kwe-cylinder liner. Ingxenye ephezulu ye-cylinder liner ivalwe ngokuqhelekileyo ishidi letsimbi kwiplani ephantsi ye-flange (i-copper okanye i-aluminium gasket, i-aluminium gasket isetyenziselwa i-aluminium alloy cylinder body, i-gasket yobhedu ayivumelekanga ukuphepha ukubola kwe-electrochemical corrosion).
