Iyo piston ndiyo yakamanikidzwa chikamu mupneumatic cylinder(made nealuminium chubhu).Kuti udzivise kuputika-negasi remakamuri maviri episton, piston seal ring inopiwa.Mhete yekupfeka papiston inogona kuvandudza kutungamira kwecylinder, kuderedza kupfekwa kwepiston yekuisa chisimbiso mhete, uye kuderedza kupokana.Mhete dzisingapfeki dzinowanzo shandisa polyurethane, polytetrafluoroethylene, machira ejira synthetic resin nezvimwe zvinhu.Iyo hupamhi hwepiston inotarirwa nehukuru hwechisimbiso mhete uye kureba kweinodiwa inotsvedza chikamu.Iyo inotsvedza chikamu ipfupi, izvo zvinogona kukonzera kupfeka nekukurumidza uye kubata.
Kudonha kwemukati nekunze kwecylinder kunonyanya kukonzerwa nekuiswa kwe eccentric yepiston tsvimbo, kusakwana mafuta ekuzora, kupfeka kana kukuvadzwa kwemhete yekuisa chisimbiso nemhete yekuisa chisimbiso, kusvibiswa mucylinder uye kukwenya papiston tsvimbo.Naizvozvo, kana kubuda kwemukati nekunze kwe cylinder kuchiitika, pakati pepiston tsvimbo inofanirwa kugadziridzwa kuti ive nechokwadi chekubatana kwepiston tsvimbo uye cylinder;uye lubricator inofanira kuongororwa nguva dzose kuti ive nechokwadi chokuti silinda yakanyatsogadziriswa;kana pane cylinder Kusvibiswa kunofanira kubviswa nenguva;kana paine mavanga pazvisimbiso zvepiston, zvinofanirwa kutsiviwa nezvitsva.Kana mhete yechisimbiso nemhete yechisimbiso zvakapfekwa kana kukuvadzwa, zvinofanirwa kutsiviwa nenguva.
Kutaura zvazviri, inofanira kunge iri lubrication pakati pepiston ring uye cylinder wall, nokuti piston uye pneumatic cylinder zviri mukubatana zvishoma.70% yekupfeka kunoitika mukukweshana kwemuganho uye kukakavara kwakasanganiswa, ndiko kuti, kukakavara panguva yekutanga-up.Kana chisimbiso nemadziro ecylinder zvazadzwa nerubricant, kusanganiswa kunogadzirwa.Panguva ino, sezvo kumhanya kunowedzera, friction coefficient ichiri kukurumidza kuderera.Kana iyo piston kumhanya ichisvika pane imwe kukosha, firimu rinoshanda rekuzora rinoumbwa kuti riwane kunhuhwirira kwemvura.Iyo nzira yekuzora iri kupfapfaidza, asi mafuta akawandisa anofanira kukweshwa kuburikidza nemhete yepiston.Mukuwedzera, pakukudza humburumbira, makomba akawanda akanaka achaumbwa pamusoro pehumburumbira liner kuchengeta mafuta, ayo anobatsira pakuzora.
Kune zvikamu zvepneumatic, kuti uwane lubrication yehupenyu hurefu, inofanirwa kusangana negrisi kuenderana uye viscosity yehwaro mafuta ayo, iyo inogona kuwana yakaderera friction coefficient uye yakanaka yekubatsira chisimbiso mhedzisiro;yakanakisa kunamatira uye kuenderana kwakanaka nerabha Uye wetting kuita;ine yakanaka lubricating properties uye inoderedza kusakara.
