Ndife akatswiri pazigawo za injini zapamwamba kwambiri.
Chilankhulo
Silinda pad ndi zotanuka kusindikiza gasket woyikidwa pakati pa silinda mutu ndi thupi olowa pamwamba. Ntchito yake ndikuletsa kutayikira kwa mpweya wa injini komanso kutulutsa madzi.
Silinda pad imakhudzana mwachindunji ndi kutentha kwapamwamba, mpweya wothamanga kwambiri komanso zoziziritsa kukhosi, zomwe ndizosavuta kuziwotcha mukamagwiritsa ntchito thirakitala, makamaka kuzungulira mutu wa silinda.
Pamene cylinder pad kuwotcha, padzakhala mpweya kutayikira ndi kutayikira madzi pansi ndege ya yamphamvu chivundikirocho, ndipo injini adzakhala overheated ndi ntchito adzakhala ofooka. Silinda ya silinda idzakhala yopunduka ndipo mphete yokana madzi ya cylinder liner idzawonongeka ngati sichipezeka ndikuchiritsidwa mu nthawi.
❶ Kuwonetsa kulephera kwakunja
Muli duwa lamafuta mu thanki yozizirira, madzi mumafuta a poto yamafuta, ngalande ya chitoliro kapena kutulutsa mafuta, mphamvu yopondereza ya silinda ndiyosakwanira.
Kutentha kwa thupi ndi wabwinobwino, koma kuzirala madzi otentha mphika, nthawi zina kwambiri kuchokera madzi thanki chivundikiro dzenje mpweya wotentha.
▶ Ntchito zake ndi izi:
(1) Pamene mbali yopsereza ili pakati pa ma cylinders awiri, ma cylinders oyendetsa gasi ndi kupanikizika sikukwanira. Utsi wogwira ntchito, kuthamanga pansi, injini ya dizilo yofooka.
(2) Pamene mbali yopsereza imapangitsa kuti silinda ilankhule ndi madzi ozizira, thovu limatuluka mu thanki yamadzi, kapena wiritsani mphikawo; Utsi chitoliro woyera utsi, ngakhale ngalande, kusiya pang'ono pali madzi poto mafuta, mlingo mafuta limatuluka.
(3) Chigawo chowotchacho chikachititsa kuti silinda ilankhule ndi bowo lopaka mafuta pa ndege ya thupi, mpweya umalowa m’njira yopaka mafuta, kutentha kwa mafuta kumakwera, mafuta amawonongeka, ndipo ngakhale chitoliro chotulutsa mpweya chimatha mafuta.
(4) Gawo lotenthedwa likamalumikizidwa ndi bowo la silinda yamutu kapena m'mphepete mwa mutu wa silinda, pamakhala chithovu chachikasu chopepuka pakutuluka kwa mpweya, ndipo pamakhala phokoso lotulutsa mpweya pazifukwa zazikulu, ndipo nthawi zina pamakhala kutayikira kwamafuta ndi kutayikira kwamadzi. Pali gawo la kaboni pamutu wa silinda ndi dzenje la bawuti.
❶Kusanthula zifukwa
(1) Choyikapo chivundikiro cha silinda chimatuluka kwambiri kuchokera pa ndege pansi pa mutu wa silinda.
(2) Ndege ya Cylinder liner protrusion yakwera kwambiri kapena kuchuluka kwa silinda iliyonse sikufanana.
(3) Mtedza wamutu wa silinda wosamangika ngati pakufunika.
(4) Ndege yapamwamba ya thupi kapena ndege yapansi ya mutu wa silinda imapotozedwa.
(5) Ubwino wa cylinder pad ndi wosauka, sungathe kuchita nawo ntchito yosindikiza.
❶Njira yolephereka
(1) Kuyika kwa chipinda choyaka moto kumatuluka kwambiri kuchokera pandege yamutu wa silinda, ndikoletsedwa kwambiri kuonjezera makokedwe a nati wamutu wa silinda.
(2) Kokani cylinder liner yomwe imatuluka kwambiri kapena yotsika kuposa ndege ya thupi ndikuyiyikanso.
(3) Limbani nati wamutu wa silinda molingana ndi torque yomwe mwalamula ndi kutsata.
(4) Konzani mutu wa silinda kapena thupi, kuti roughness ya pamwamba ikwaniritse zofunikira.
(5) Pofuna kutsimikizira khalidwe losindikiza, pad yosankhidwa ya silinda iyenera kukhala yofanana ndi kukula kwake ndi makulidwe monga silinda yapachiyambi, pamwamba payenera kukhala yosalala, m'mphepete mwake iyenera kumangidwa mwamphamvu, ndipo palibe zoyamba, sag, zou ndi dzimbiri chodabwitsa.
