Ukuphucula ubomi betywina, ukuchasana kwe-frictional of the main seal kufuneka kube ngaphantsi, okudinga ifilimu yeoli kwindawo yokutyibilika kwetywina eliphambili.Olu luhlu lwee-coefficients of friction apho ifilimu yeoli yenziwe khona iyaziwa kwithiyori ye-lubrication njenge-lubrication fluid.Kulo luhlu, indawo yokusebenza yesitywina idibene ne-cylinder okanye intonga ngokusebenzisa ifilimu yeoli, xa isitywina sinobomi obude benkonzo ngaphandle kokugqoka, nangona ukunyakaza kwesihlobo kwenzeka.Ngesi sizathu, kubalulekile ukuyila ukuhanjiswa koxinzelelo olufanayo ukuze kuveliswe ifilimu yeoli eyona ilungileyo kumphezulu wokutyibilika.Oku kuyinyani kungekuphela nje kwiitywina ezidityanisiweyo kodwa kuzo zonke izitywina ezisebenza ngehydraulic.
Imigaqo yoyilo lweetywina ezidibeneyo ibandakanya oku kulandelayo:
① Umyinge wokunyanzeliswa ngokubanzi kwetywina elidityanisiweyo lixatyiswe ngokufanelekileyo ngokweempawu zemathiriyeli.Umsantsa phakathi kwemveliso kunye ne-groove kwi-free state ishiywe, kodwa ayikho enkulu kakhulu ukuphepha ukugubha kwi-groove.
②Iringi yokutywina:Itywina eliphambili.Ubukhulu bayo abunakutyeba kakhulu, ngokubanzi kwi-2 ~ 5mm, ngemathiriyeli ethile yokutywina;ububanzi bayo abunakuba banzi kakhulu, esebenzayo ukutywina ububanzi lidlula ixabiso elithile kunokuqwalaselwa ukongeza igroove yokuthambisa, ukuphepha ukukhuhlana owomileyo kunye nokurhubuluza isenzeko.
③Elastomer: indima kukubonelela ngenkxaso ngokuqhubekayo ukuqinisekisa isiphumo sokutywinwa kwetywina elidityanisiweyo.Ngokobulukhuni bezinto eziphathekayo, imodyuli e-elastiki, njl.njl. ukuthatha izinga loxinzelelo olufanelekileyo, ububanzi bayo kunye nobubanzi be-groove ukushiya isithuba esifanelekileyo phakathi.Qinisekisa ukuba i-elastomer inendawo eyaneleyo yokuhamba emva kwe-extrusion.
④ Umsesane wokugcina: Indima kukuqinisekisa ukuzinza kwendawo ye-elastomer emva kokufakwa kwi-groove, ukuze kuphuculwe uzinzo jikelele lomsesane wokutywina.Idityaniswe nomsesane wokutywina kunye noyilo olupheleleyo lwe-elastomer.
⑤Indandatho yokukhokela: Indima kukukhokela nokuqinisekisa ukusebenza kakuhle kunye nokuzinza kwepiston kwi-cylinder kunye nokukhusela umonakalo kwi-cylinder surface yensimbi ngokuqhagamshelana phakathi kwensimbi yepiston kunye ne-cylinder steel barrel.Ulwakhiwo luqhelekile ngokweGFA/GST.
