Piston ke karolo e hatelletsoeng ka har'a silinda ea moea ('mele o entsoeng ke 6063-T5 aluminium tube).E le ho thibela ho phatloha ha khase ea likamore tse peli tsa piston, ho fanoa ka reng ea tiiso ea piston.Rela ea ho roala piston e ka ntlafatsa tataiso ea silinda, ea fokotsa ho roala ha lesale la ho tiisa piston, le ho fokotsa ho hanyetsa likhohlano.Mehele e sa keneng hangata e sebelisa polyurethane, polytetrafluoroethylene, masela a maiketsetso a resin le lisebelisoa tse ling.Bophara ba piston bo khetholloa ke boholo ba lesale la ho tiisa le bolelele ba karolo e hlokahalang ea ho thella.Karolo e thellang e khuts'oane haholo, e ka bakang hore motho a khathale le ho tsietsana.
Ho lutla ha ka hare le ka ntle ha silinda ea moea e bakoa ke ho kenngoa ha piston rod, lubricant e sa lekaneng, ho roala kapa ho senya lesale la ho tiisa le lesale la ho tiisa, litšila tse ka har'a cylinder le mengoapo holim'a molamu oa piston.Ka hona, ha ho tsoa ka hare le ka ntle ho cylinder ea pneumatic ho etsahala, setsi sa molamu oa piston se lokela ho lokisoa ho netefatsa hore coaxiality ea piston rod le cylinder;mme setlolo se lokela ho hlahlojwa kgafetsa ho etsa bonnete ba hore silindara ya moya e tlotsitswe hantle;haeba ho na le cylinder Litšila li lokela ho tlosoa ka nako;ha ho e-na le likheo holim'a litiiso tsa piston, li lokela ho nkeloa sebaka ke tse ncha.Ha selikalikoe sa tiiso le selikalikoe sa tiiso se apere kapa se senyehile, se lokela ho nkeloa sebaka ka nako.
Ha e le hantle, e lokela ho ba lubrication pakeng tsa lesale la piston le lerako la silinda, hobane piston le silinda li kopane hanyenyane.70% ea ho roala e etsahala ka likhohlano tsa moeli le likhohlano tse tsoakiloeng, ke hore, likhohlano nakong ea ho qala.Ha tiiso le lerako la silinda li tlatsitsoe ka mokhoa o itseng oa lubricant, likhohlano tse tsoakiloeng lia thehoa.Nakong ena, ha lebelo le ntse le eketseha, coefficient ea likhohlano e ntse e fokotseha ka potlako.Ha lebelo la piston le fihla boleng bo itseng, filimi e sebetsang ea lubrication e thehoa ho finyella lubrication ea mokelikeli.Mokhoa oa ho tlotsa ke oa ho fafatsa, empa oli e feteletseng e tlameha ho hlajoa ka lesale la piston.Ho phaella moo, ha u lokisa moqomo, likoti tse ngata tse ntle li tla thehoa holim'a cylinder liner ho boloka oli, e leng molemo ho lubrication.
Bakeng sa likarolo tsa pneumatic, ho finyella lubrication ea nako e telele, e tlameha ho kopana le ho lumellana ha mafura le viscosity ea oli ea eona ea motheo, e ka finyellang coefficient e tlaase ea likhohlano le phello e ntle ea ho tiisa;ho khomarela hantle le ho lumellana hantle le rabara Le ts'ebetso ea ho kolobisa;e na le thepa e ntle ea ho tlotsa le ho fokotsa ho khathala.
