I-piston yinxalenye yoxinzelelo kwi-cylinder ye-pneumatic (umzimba owenziwe yi-6063-T5 ityhubhu ye-aluminium).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 kunye nangaphandle kwe-cylinder ye-pneumatic ngokusisiseko kubangelwa ukufakwa kwe-eccentric ye-piston rod, i-lubricant eyaneleyo, ukugqoka okanye umonakalo kwindandatho yokutywina kunye nokutywinwa kwentsimbi, ukungcola kwi-cylinder kunye nemikrwelo kwintonga yepiston.Ngoko ke, xa ukuvuza kwangaphakathi nangaphandle kwe-cylinder ye-pneumatic kwenzeka, umbindi wentonga ye-piston kufuneka ulungiswe ukuze uqiniseke ukuba i-coaxiality ye-piston rod kunye ne-cylinder;kwaye i-lubricator kufuneka ihlolwe rhoqo ukuze kuqinisekiswe ukuba isilinda se-pneumatic 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 kube kukuthambisa phakathi kweringi yepiston kunye nodonga lwesilinda, kuba ipiston kunye necylinder 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.
