Nhanganyaya: Iyo silinda liner ndiyo moyo chikamu cheinjini. Nzvimbo yaro yemukati, pamwe nepamusoro pepiston, mhete yepiston, uye pasi pemusoro wecylinder, inoumba kamuri yekupisa yeinjini, uye inotungamira iyo inodzokororwa mutsara kufamba kwepiston. Iyo yemukati yehumburumbira ndeyese gungano uye nzvimbo yekushanda, uye kunaka kwekugadziriswa kwayo kunobata zvakananga kuita kwegungano uye kushanda kwebasa rejini.
Kukadzi 2008 isati yasvika, matambudziko anotevera aivepo muChinese marine marine engine cylinder liners:
① Chiyero chekugadzirisa cheindasitiri yemumba yeChina chakaderera, madziro emukati ecylinder liner akagadzirwa neakajairika honing mesh, mafuta ekuzora uye kudonhedza mhedzisiro haina kunaka, hupenyu hwesevhisi yecylinder liner ipfupi, injini yekushandisa simba yakakwira. , uye kubuda kunodarika mwero;
②Tembiricha yekushanda yekamuri yekupisa iri pamusoro pe1000 ℃ panguva yekushanda kweinjini, uye fusing kupfeka iri nyore kwazvo kugadzira kabhoni deposits, zvichikonzera kupfeka kweabrasive. Iyo inoderedza mutengo wekuchengetedza weiyo inodhura kwazvo marine injini silinda liner;
③ Pamberi paKukadzi 2008, mazhinji emacylinder liner einjini dzemugungwa akagadzirwa nepamusoro phosphorus cast iron, boron cast iron, vanadium titanium cast iron, low alloy cast iron, nezvimwewo. yakazara mechanicha zvinhu zvechinyorwa Simba rakaderera uye kuoma, kushomeka kusakara, hupenyu hupfupi hwechigadzirwa, zvakaoma kuzadzisa zvinodiwa zvemugungwa injini; Kuita kwakanaka, kurongeka kwepamusoro uye kuderera kwakadzika, iyo silinda liner zvinhu zviripo Kukadzi 2008 isati yasvika haigone kuzadzisa zvinodiwa.
marudzi maviri emarine liner: dry liner uye wet liner
1. Dry cylinder liner zvinoreva kuti pamusoro pe cylinder liner haibate chinotonhodza. Kuti ive nechokwadi chekupisa kupisa mhedzisiro uye nekumisikidzwa kwecylinder liner, uye kuwana yakakwana chaiyo yekubata nzvimbo ine cylinder block, pamusoro peiyo yakaoma cylinder liner uye yemukati nekunze nzvimbo yecylinder block inotakura gomba inobatana nayo. vane yakakwirira machining kururama. Dry cylinder liners ane madziro matete uye mamwe angori 1mm gobvu. Mugumo wepazasi wedenderedzwa rekunze reiyo humburumbira liner ine diki taper angle yekutsikirira cylinder block. Pamusoro peiyo yakaoma liner (kana pasi pe cylinder bore) inowanikwa kana isina flanges. Flanged ine kupindira kushoma nekuti iyo flange inobatsira pakumisikidzwa kwayo.
Zvakanakira cylinder liner yakaoma ndeyokuti haisi nyore kudonha, kuomarara kwechimiro chesilinda yakakura, huwandu hwemuviri hudiki, hapana cavitation, uye chinhambwe pakati pemasilinda madiki; izvo zvinokanganisa hazvibatsiri kugadzirisa uye kutsiva, uye kushayikwa kwekupisa kupisa. Mune injini dzine dhayamita yakaboora isingasviki 120mm, inoshandiswa zvakanyanya nekuda kwehudiki hwayo hwekupisa. Oiri-isina air compressor cylinder liner vagadziri vanotenda kuti zvakakodzera kutaura kuti yakaoma silinda liner yekunze kwemotokari injini dzedhiziri iri kukura nekukurumidza.
2. Pamusoro pemvura ye cylinder liner inosangana zvakananga neinotonhodza, uye rusvingo rwayo rwakakura kudarika iyo yakaoma cylinder liner. Iyo radial yekumisikidzwa kweyet silinda liner kazhinji inotsamira pamabhandi epamusoro uye epasi maviri anobudikira annular anobatana nepakati pakati pe cylinder block, uye axial chinzvimbo ndechekushandisa yakaderera ndege yekumusoro flange. Chikamu chezasi checylinder liner chakavharwa ne 1 kusvika ku3 inodzivirira kupisa uye mafuta-inodzivirira rubber sealing mhete. Nekuwedzera kwekusimba kwemainjini edhiziri, iyo cavitation yemacylinder liners yave dambudziko rakakurumbira, saka mamwe macylinder enjini edhiziri ane zvindori zvitatu zvekuvharisa, uye chikamu chepamusoro chekupedzisira chiri kusangana neinotonhodza, iyo inogona. kwete chete kudzivirira ngura yenzvimbo yekushanda, Zviri nyore kuparadzanisa uye kuunganidza, uye inogona kutora vibration uye kuderedza cavitation. Mamwe epamusoro nepakati maviri akagadzirwa ne ethylene-propylene synthetic rabha yekusimbisa inotonhorera; iyo yepasi inogadzirwa nesilicone zvinhu kuvhara mafuta, uye maviri acho haagone kuiswa zvisirizvo. Vamwe vanoisawo mhete yekuisa chisimbiso pahumburumbira kuti ivandudze kusimba kwecylinder liner. Chikamu chepamusoro checylinder liner chinowanzovharwa nesimbi pepa pazasi ndege yeflange (mhangura kana aluminium gasket, aluminium gasket inoshandiswa kune aluminium alloy cylinder body, copper gasket haibvumidzwe kudzivirira electrochemical corrosion).
