Ipiston yinxalenye yoxinzelelo kwi-cylinder ye-pneumatic(made ngetyhubhu yealuminiyam).Ukuze uthintele ukuvuthela kwegesi kumagumbi amabini episton, i-piston seal ring inikezelwa.Umsesane wokunxiba kwipiston unokuphucula isikhokelo sesilinda, ukunciphisa ukunxitywa kweringi yokutywina yepiston, kunye nokunciphisa ukuxhathisa ukukhuhlana.Iringi ezikwaziyo ukunxitywa ngokuqhelekileyo zisebenzisa i-polyurethane, i-polytetrafluoroethylene, ilaphu elenziwe nge-resin eyenziwe ngelaphu kunye nezinye izinto.Ububanzi bepiston buchongwa ngubukhulu bendandatho yokutywina kunye nobude benxalenye efunekayo yesilayidi.Indawo etyibilikayo imfutshane kakhulu, nto leyo enokubangela ukuguga kwangaphambili kunye nokuxhuzula.
Ukuvuza kwangaphakathi nangaphandle kwe-cylinder ngokusisiseko kubangelwa ukufakwa kwe-eccentric ye-piston rod, i-lubricant eyaneleyo, ukugqoka okanye umonakalo kwindandatho yokutywina kunye nokutywina, ukungcola kwi-cylinder kunye nemikrwelo kwintonga yepiston.Ngoko ke, xa ukuvuza kwangaphakathi nangaphandle kwe-cylinder kwenzeka, umbindi wentonga yepiston kufuneka ilungiswe ukuze kuqinisekiswe i-coaxiality ye-piston rod kunye ne-cylinder;kunye ne-lubricator kufuneka ihlolwe rhoqo ukuqinisekisa ukuba isilinda sifakwe kakuhle;ukuba kukho isilinda Ukungcola kufuneka kususwe ngexesha;xa kukho imikrwelo kwiipiston seals, kufuneka zitshintshwe zibe zintsha.Xa umsesane wokutywina kunye nomsesane wokutywina zinxitywe okanye zonakele, kufuneka zitshintshwe ngexesha.
Ukuthetha ngokuchanekileyo, kufuneka ibe yi-lubrication phakathi kweringi yepiston kunye nodonga lwesilinda, kuba ipiston kunye ne-pneumatic cylinder zinxibelelana kancinci.I-70% yokugqoka iyenzeka kwi-friction yomda kunye nokuxuba okuxubileyo, oko kukuthi, ukuxutywa ngexesha lokuqalisa.Xa isitywina kunye nodonga lwe-cylinder luzaliswe ngokuyinxenye nge-lubricant, i-friction edibeneyo yenziwa.Ngeli xesha, njengoko isantya sinyuka, i-coefficient ye-friction isahla ngokukhawuleza.Xa isantya sepiston sifikelela kwixabiso elithile, ifilimu yokuthambisa esebenzayo yenziwa ukuphumeza ukuthambisa ulwelo.Indlela yokuthambisa iyafafaza, kodwa i-oyile egqithisileyo kufuneka ichithwe ngeringi yepiston.Ukongezelela, xa ulungisa i-cylinder, imingxuma emininzi emihle iya kuqulunqwa kumphezulu we-cylinder liner ukugcina ioli, enenzuzo kwi-lubrication.
Kumacandelo e-pneumatic, ukuphumeza i-lubrication yexesha elide, kufuneka ihlangabezane ne-grease consistency kunye ne-viscosity yeoli yayo yesiseko, enokufikelela kwi-coefficient ye-friction ephantsi kunye nesiphumo esihle sokutywinwa kokuncedisa;ukunamathela okugqwesileyo kunye nokuhambelana kakuhle nerabha kunye nokusebenza kokumanzisa;ineempawu ezilungileyo zokuthambisa kunye nokunciphisa ukuguga.
