Cylinder liner imagawidwa m'magulu awiri: cylinder liner youma ndi yonyowa ya silinda. Silinda ya silinda yomwe msana wake sukhudzana ndi madzi ozizira imatchedwa cylinder liner youma, ndipo silinda yomwe msana wake umakhudzana ndi madzi ozizira ndi chonyowa cha silinda. Makulidwe a liner youma ya silinda ndi yopyapyala, kapangidwe kake ndi kosavuta, ndipo kukonza kwake ndikosavuta. Chingwe chonyowa cha silinda chimalumikizana mwachindunji ndi madzi ozizira, motero chimakhala chopindulitsa kuziziritsa kwa injini komanso kutsika pang'ono ndi kuchepetsa kulemera kwa injini. Nkhaniyi ifotokoza mitundu ingapo ya zomwe zimayambitsa kulephera kwa cylinder liner.

1. Khoma lamkati la cylinder liner limakokedwa

Mawonekedwe: Zizindikiro zosagwirizana komanso zosasinthika m'mphepete mwa silinda, nthawi zina zitsulo zowoneka bwino za pisitoni zowotcherera pakhoma la silinda.

Chifukwa: Zifukwa zokoka silinda ndizovuta, ndipo pali zifukwa zopangidwira, monga kusankha kwa zipangizo, kutsimikiza kwa kukula kwa kusiyana, ngati kukhazikitsidwa kwa chipangizocho kuli koyenera, kaya kukonzedwa kwapangidwe kuli koyenera, kaya pamwamba roughness ndi oyenera, ndi dongosolo mafuta ndi kuziziritsa. Kaya ndi yangwiro kapena ayi, malinga ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kabwino kabwino kabwinobwinobwinobwinobwinobwinokeke!

Mafuta opaka silinda ndi osakwanira kapena mafuta amasokonekera, ndipo chitsulo chimalumikizidwa mwachindunji ndipo silinda imakoka. Zifukwa za kudzoza koyipa kwa silinda ndi: mafuta mu poto yamafuta ndi ochepa kwambiri kapena mtundu wamafutawo ndi woyipa kwambiri, kutentha kwa injini ya dizilo ndikokwera kwambiri, kapena mphete za pistoni (makamaka mphete zamafuta) ) kapena kulephera, etc.

Kuti mugwire bwino ntchito mu nthawi yaifupi kwambiri, nthawi yothamanga komanso kugawa katundu kuyenera kuganiziridwa. Ngakhale kuthamanga-kuthamanga kumakhala kochepa kwambiri kwa nthawi yayitali, kuthamanga sikungatheke, ndipo ngati ntchito yolemetsa kwambiri ikuthamangitsidwa, idzachititsa kuti silinda ikoke. Chifukwa chake, munthawi yoyendetsa injini ya dizilo, ziyenera kukumbukiridwa kuti kuchuluka kwa jakisoni wamafuta kuyenera kukulitsidwa moyenera panthawi yothamanga; mphete ya pistoni ikasinthidwa, iyenera kuthamanga pansi pa katundu wochepa kwa nthawi; pisitoni ndi cylinder liner zitasinthidwa, kuthamanga kuyenera kuchitidwa musanawonjezere ntchito yolemetsa.

Kuzizira kosakwanira kumayambitsa kutentha kwambiri kwa silinda ndi pisitoni, komanso mafuta osakwanira; Kusazizira bwino kumapangitsa kuti pisitoni ndi cylinder liner zitenthedwe kwambiri ndikufutukuka ndi kupunduka, kutaya chilolezo choyambirira ndikukoka silinda. Zifukwa za kuzizira kozizira ndi: kusakwanira kotulutsa mphamvu ya pampu yamadzi ozizira, madzi osakwanira Osakwanira kapena kusokonezedwa; chipinda cha madzi ozizira ndi dzimbiri kapena zakuda; madzi amakhala ndi thovu la mpweya, lomwe limadziunjikira m'chipinda chozizira ndipo silimatulutsidwa, zomwe zimapangitsa kuti mpweya usavutike; madzi abwino ndi akuda kwambiri ndipo kutentha kwamadzi ndikwambiri.

(4) Mphete ya piston sikugwira ntchito bwino:

Ngati chilolezo chotsegulira chili chochepa kwambiri, mphete ya pistoni imasweka; ngati danga pakati pa thambo ndi pansi ndi laling'ono kwambiri, mphete ya pistoni idzakanidwa; ma depositi a carbon ochuluka amapangitsa mphete ya pistoni kumamatira ku ring groove ndikutaya kukhazikika kwake, zomwe zimapangitsa kuthyoka kapena kutulutsa mpweya; chilolezo chotsegulira ndi chachikulu kwambiri kapena kuvala kuli koopsa, kutulutsa mpweya kumachitika. Kutayikira kwa gasi kumawononga filimu yamafuta opaka mafuta ndipo kumapangitsa kutentha kwapamtunda kwambiri. Mphete ya pisitoni ikathyoka, zidutswazo zimakhala zosavuta kugwera mu silinda ya pisitoni, zomwe zimapangitsa kuti silinda kukoka ndi kuluma silindayo.

Kuyaka kosakwanira kumabweretsa zotsalira zoyaka; pambuyo-kuyaka ndi kwambiri, amene kumawonjezera utsi kutentha mpweya, ndi njira luso si anatengedwa mu nthawi; cylinder lubrication base value siyenera. Silinda imakokedwa chifukwa cha kuwonjezereka kwa kutentha kapena kusayenda bwino kwa magawo osuntha.
