Ukuze uthuthukise ukuphila kwezimpawu, ukumelana nokungqubuzana kophawu oluyinhloko kudinga ukuba kube kuncane, okudinga ifilimu kawoyela endaweni eshelelayo yophawu oluyinhloko.Lolu hlu lwama-coefficients of friction lapho ifilimu kawoyela kwakheka khona nalo lwaziwa ngethiyori yokugcoba njengokugcoba uketshezi.Kulolu hlu, indawo yokusebenza yophawu ithintana nesilinda noma induku ngokusebenzisa ifilimu yamafutha, lapho uphawu lunenkonzo ende yokuphila ngaphandle kokugqoka, ngisho nalapho ukunyakaza okuhlobene kwenzeka.Ngenxa yalesi sizathu, kubalulekile ukuklama ukusatshalaliswa kwengcindezi yokuxhumana okufanayo ukuze kukhiqizwe ifilimu kawoyela esezingeni eliphezulu endaweni eshelelayo.Lokhu akulona iqiniso kuphela ezimpahleni ezihlanganisiwe kodwa kuzo zonke izimpawu ze-hydraulic.
Izimiso zokuklama zezigxivizo ezihlanganisiwe zihlanganisa okulandelayo:
① Izinga lokuminyanisa lilonke lenhlanganisela yophawu linakwa ngokufanelekile ngokuya ngezakhiwo zezinto ezibonakalayo.Igebe phakathi komkhiqizo kanye ne-groove esimweni samahhala lishiywe, kodwa alilikhulu kakhulu ukugwema ukuzamazama emgodini.
②Indandatho yokuvala: Uphawu oluyinhloko.Ugqinsi lwawo angeke lube lukhulu kakhulu, ngokuvamile lube ngu-2 ~ 5mm, ngezinto ezithile zokuvala;ububanzi bayo abukwazi ukuba banzi kakhulu, ngempumelelo band ukuvala ububanzi idlula inani elithile kungabhekwa ukwengeza lubrication inkatho, ukugwema ukungqubuzana okomile futhi kukhasa isenzeko.
③I-Elastomer: indima ukuhlinzeka ngokuqhubekayo ukusekela ukuze uqinisekise umphumela wokuvala uphawu oluhlanganisiwe.Ngokusho kobunzima bezinto ezibonakalayo, i-elastic modulus, njll. ukuthatha izinga lokucindezela elifanele, ububanzi bayo kanye nobubanzi be-groove ukushiya igebe elifanele phakathi.Qinisekisa ukuthi i-elastomer inesikhala esanele sokuhamba ngemva kokukhishwa kwe-extrusion.
④ Ukugcina indandatho: Indima iwukuqinisekisa ukuzinza kwendawo ye-elastomer ngemva kokungena emseleni, ukuze kuthuthukiswe ukuzinza kukonke kwendandatho yokuvala.Kuhlanganiswe nendandatho yophawu kanye nomklamo jikelele we-elastomer.
⑤Indandatho yokuqondisa: Indima ukuqondisa nokuqinisekisa ukusebenza okushelelayo nokuzinzile kwepiston kusilinda kanye nokuvikela ukulimala endaweni yensimbi yesilinda ngokuthintana phakathi kwensimbi ye-piston kanye ne-cylinder steel barrel.Isakhiwo ngokuvamile siyi-GFA/GST ejwayelekile.
