Ipiston iyingxenye ecindezelwe kusilinda somoya (umzimba owenziwe ngeshubhu ye-aluminium engu-6063-T5).Ukuze uvimbele ukuqhuma kwegesi kwamakamelo amabili e-piston, kunikezwa indandatho yophawu lwe-piston.Indandatho ekwi-piston ingathuthukisa ukuqondiswa kwesilinda, inciphise ukuguga kweringi yokuvala i-piston, futhi inciphise ukumelana nokungqubuzana.Izindandatho ezikwazi ukumelana nokugqokwa ngokuvamile zisebenzisa i-polyurethane, i-polytetrafluoroethylene, i-cloth synthetic resin nezinye izinto.Ububanzi be-piston bunqunywa ubukhulu bendandatho yokuvala kanye nobude bengxenye edingekayo yokushelela.Ingxenye eshelelayo yimfushane kakhulu, okungase kubangele ukuguga ngaphambi kwesikhathi nokubanjwa.
Ukuvuza kwangaphakathi nangaphandle kwesilinda somoya ngokuyisisekelo kubangelwa ukufakwa kwe-eccentric kwenduku ye-piston, i-lubricant enganele, ukugqokwa noma ukulimala kwendandatho yokuvala kanye nendandatho yokuvala, ukungcola ku-cylinder kanye nemihuzuko kwintonga ye-piston.Ngakho-ke, lapho ukuvuza kwangaphakathi nangaphandle kwe-cylinder ye-pneumatic kwenzeka, isikhungo se-piston rod kufanele silungiswe ukuze kuqinisekiswe ukuhlangana kwe-piston rod kanye ne-cylinder;futhi i-lubricator kufanele ihlolwe njalo ukuze kuqinisekiswe ukuthi isilinda somoya sigcotshwe kahle;uma kukhona isilinda Ukungcola kufanele kususwe ngesikhathi;lapho kukhona imihuzuko ezigxivizweni ze-piston, kufanele kushintshwe ezintsha.Lapho indandatho yophawu nendandatho yophawu kugqokwa noma konakele, kufanele kushintshwe ngesikhathi.
Uma sikhuluma kahle, kufanele kube ukuthambisa phakathi kweringi yepiston nodonga lwesilinda, ngoba ipiston nesilinda kuxhumene kancane.I-70% yokugqoka kwenzeka ekungqubuzaneni komngcele kanye nokungqubuzana okuxubile, okungukuthi, ukungqubuzana ngesikhathi sokuqala.Lapho uphawu kanye nodonga lwesilinda kugcwele ingxenye yokugcoba, kwakheka ukungqubuzana okuxubile.Ngalesi sikhathi, njengoba isivinini sikhula, i-coefficient yokungqubuzana isancipha ngokushesha.Lapho isivinini se-piston sifinyelela inani elithile, ifilimu yokugcoba ephumelelayo iyakhiwa ukuze kuzuzwe ukugcotshwa kwamanzi.Indlela yokugcoba iwukuchaphaza, kodwa uwoyela oweqile kufanele uchithwe ngeringi yepiston.Ngaphezu kwalokho, lapho ucija isilinda, kuzokwakhiwa imigodi eminingi emihle phezu kwe-cylinder liner ukugcina uwoyela, okuzuzisa ukugcoba.
Ezingxenyeni ze-pneumatic, ukuze kuzuzwe ukugcotshwa kwempilo ende, kufanele kuhlangabezane nokuvumelana kwamafutha kanye ne-viscosity yamafutha ayo ayisisekelo, angafinyelela i-coefficient ephansi ye-friction kanye nomphumela omuhle wokufaka uphawu osizayo;ukunamathela okuhle kakhulu nokuhambisana okuhle nerabha Kanye nokusebenza kokumanzisa;inezinto ezinhle zokugcoba futhi inciphisa ukuguga.
