1. Ukufakwa kwe-cylinder liner

Xa injini isebenza, umgangatho wangaphakathi we-cylinder liner udibana ngokuthe ngqo kunye negesi ephezulu yokushisa, kwaye ubushushu kunye noxinzelelo kutshintsha rhoqo, kwaye ixabiso lalo ngokukhawuleza liphezulu kakhulu, elibeka umthwalo omkhulu we-thermal kunye nomthwalo womatshini. kwicylinder. I-piston yenza i-high-speed reciprocating linear motion kwi-cylinder, kwaye udonga lwangaphakathi lwe-cylinder lusebenza njengesikhokelo.

Imeko ye-lubrication yodonga lwangaphakathi lwe-cylinder impofu, kwaye kunzima ukwenza ifilimu yeoli. Iguga ngokukhawuleza ngexesha lokusetyenziswa, ngakumbi kwindawo ekufutshane neziko eliphezulu lokufa. Ukongezelela, iimveliso zokutsha ziphinde zigxumeke kwi-cylinder. Ngaphantsi kweemeko zokusebenza ezinzima ngolo hlobo, ukunxiba isilinda akunakuphepheka. Ukunxiba kwe-cylinder kuya kuchaphazela ukusebenza kwe-injini, kwaye i-cylinder liner nayo iyingxenye esengozini ye-injini ye-diesel.

Amanqaku ofakelo lwe-cylinder liner ami ngolu hlobo lulandelayo:

(1) Beka i-cylinder liner ngaphandle kweringi yokuthintela amanzi kumzimba wesilinda kuvavanyo lokuqala, ukuze ijikeleze ngokuguquguqukayo ngaphandle kokungcangcazela okucacileyo, kwaye kwangaxeshanye ujonge ukuba ubungakanani benyathelo le-cylinder liner ngaphezulu kwendiza yomzimba we-cylinder. ingaphakathi koluhlu oluxeliweyo .

(2) Kungakhathaliseki ukuba i-cylinder liner intsha okanye indala, zonke izangqa ezintsha zokuvala amanzi kufuneka zisetyenziswe xa kufakwa i-cylinder liner. Irabha yeringi yokuthintela amanzi kufuneka ithambe kwaye ingabi nazintanda, kwaye ukucaciswa kunye nobukhulu kufuneka buhlangabezane neemfuno zenjini yokuqala.

3 inombolo yolandelelwano lomngxuma Kumngxunya we-cylinder ohambelanayo, sebenzisa isixhobo sokufakela esikhethekileyo ukucofa kancinci i-cylinder liner kwi-cylinder ngokupheleleyo, ngoko ke. ukuba igxalaba kunye nomphezulu we-cylinder spigot ziqhotyoshelwe ngokusondeleyo, kwaye akuvumelekanga ukusebenzisa ihamile yesandla ukuyityumza ngamandla.

Emva kofakelo, sebenzisa isalathisi sokudayela sangaphakathi ukulinganisa, kunye ne-deformation (ukunciphisa ubungakanani kunye nokulahleka kokujikeleza) kwindandatho yokuthintela amanzi ayiyi kudlula i-0.02 mm. Xa i-deformation inkulu,

I-cylinder liner kufuneka itsalwe ukuze kulungiswe iringi yokuthintela amanzi kwaye emva koko ibuyiselwe. Emva kokuba i-sleeve ye-cylinder ifakwe, ihlombe elingaphezulu lomkhono we-cylinder kufuneka liphume kwi-plane yomzimba we-cylinder ngo-0.06-0.12 mm, kwaye lo mlinganiso kufuneka uhlolwe ngaphambi kokufaka indandatho yokuthintela amanzi. Ukuba i-protrusion incinci, ishidi lobhedu lobunzima obufanelekileyo linokuthi lifakwe kwigxalaba eliphezulu le-cylinder liner; xa i-protrusion inkulu kakhulu, ihlombe eliphezulu le-cylinder liner kufuneka liguqulwe.
