Injini inofanira kuparadzaniswa uye kuchinjwa panguva yekugadziriswa. Gungano mushure mekugadzirisa ibasa rinokosha. Nzira yekuisa sei zvikamu muinjini yakakwana yedhiziri ine yakakwira tekinoroji zvinodiwa. Kunyanya, hutano hwegungano hunokanganisa zvakananga hupenyu hwebasa rejini uye kuwanda kwekugadzirisa. Izvi zvinotevera zvinotsanangura nzira yegungano yezvikamu zvikuru zvejini.
1. Kuiswa kwe cylinder liner
Kana injini iri kushanda, nzvimbo yemukati ye cylinder liner inosangana zvakananga nepamusoro-tembiricha gasi, uye tembiricha yayo uye kudzvanywa kuri kuchinja kazhinji, uye kukosha kwayo kwepakarepo kwakakwira zvakanyanya, izvo zvinoisa mutoro mukuru wekupisa uye mechanical load. pahumburumbira. Iyo piston inogadzira yakakwirira-kumhanya inodzosera mutsara kufamba muhumburumbira, uye madziro emukati ehumburumbira anoita segwara.
Mamiriro ekuzora emukati memadziro e cylinder akashata, uye zvakaoma kuumba firimu remafuta. Inopera nekukurumidza panguva yekushandiswa, kunyanya munzvimbo iri pedyo nepamusoro penzvimbo yakafa. Mukuwedzera, zvigadzirwa zvinopisa zvinosvibisawo kune cylinder. Pasi pemamiriro ekushanda akaoma kudaro, kupfeka silinda hakudzivisiki. Kupfeka kwecylinder kuchakanganisa kushanda kweinjini, uye silinda liner zvakare iri panjodzi chikamu cheinjini yedhiziri.
Mapoinzi ekuisa cylinder liner ndeaya anotevera:
(1) Isa cylinder liner isina mvura inovharira mhete mumuviri wecylinder kuti uedze kutanga, kuitira kuti ikwanise kutenderera ichitenderera pasina kuzununguka kuri pachena, uye panguva imwe chete tarisa kana chiyero chesilinda liner nhanho pamusoro pe cylinder body plane. iri mukati mechikamu chakatarwa .
(2) Pasinei nokuti cylinder liner itsva kana yekare, zvindori zvitsva zvekuvhara mvura zvinofanira kushandiswa pakuisa cylinder liner. Iyo rabha yemvura inovhara mhete inofanirwa kuve yakapfava uye isina kuputika, uye iyo yakatarwa uye saizi inofanirwa kusangana nezvinodiwa zveinjini yepakutanga.
(3) Paunenge uchidzvanya mucylinder liner, unogona kuzora imwe sipo mvura yakatenderedza mvura inovharira mhete kuti ifambise kudzosa, uye unogona zvakare kuzora imwe nenzira kwayo pahumburumbira, wobva wasundira zvinyoro cylinder liner mukati zvichienderana necylinder yakanyorwa. gomba kutevedzana nhamba Mugomba recylinder rinoenderana, shandisa yakakosha yekuisa chishandiso kudzvanya zvishoma nezvishoma silinda liner mucylinder zvachose, saka kuti bendekete nepamusoro pe cylinder spigot zvakanyatsobatanidzwa, uye hazvibvumirwi kushandisa nyundo yemaoko kuipwanya zvakasimba.
Mushure mekuisa, shandisa iyo yemukati dhayamita dial chiratidzo kuyera, uye deformation (dimension kuderedzwa uye kurasikirwa kwekutenderera) yemvura inovhara mhete haifaniri kudarika 0.02 mm. Kana deformation yakakura,
Humburumbira liner inofanira kudhonzwa kuti igadzirise ring inovharisa mvura yozoiswazve. Mushure mekunge silinda yaiswa sleeve, bendekete repamusoro resilinda rinofanirwa kubuda kubva mundege yemuviri wecylinder ne 0.06-0.12 mm, uye chiyero ichi chinofanira kuongororwa usati waisa mhete yekuvhara mvura. Kana iyo protrusion iri diki, pepa remhangura rehukobvu hwakakodzera rinogona kuputirwa pabendekete repamusoro re cylinder liner; apo kuputika kwakanyanya, pfudzi repamusoro re cylinder liner rinofanira kushandurwa.
