Ukuze uthuthukise ukuphila kwezimpawu, ukumelana nokungqubuzana kophawu oluyinhloko kufanele kube kuncane, okudinga ifilimu kawoyela endaweni eshelelayo yophawu oluyinhloko.Lolu hlu lwama-coefficients okungqubuzana okwakhiwa kwefilimu kawoyela lwaziwa nangokuthi i-fluid lubrication kuthiyori yokugcoba.Kulolu hlu, uphawu lwe-wo.i-rking surface ku-cylinder noma induku ithintwa ifilimu yamafutha, khona-ke, uphawu lunempilo ende yesevisi ngaphandle kokugqoka, ngisho noma kwenzeka ukunyakaza okuhlobene.Ngakho-ke, ukucatshangelwa okufanele kunikezwa ekwakhiweni kokusatshalaliswa kwengcindezi yokuxhumana okulingana kahle, okuvumela ifilimu kawoyela esezingeni eliphezulu ukuthi yenziwe endaweni eshelelayo.Lokhu akulona iqiniso kuphela ezimpahleni ezihlanganisiwe, kodwa futhi kuzo zonke izimpawu ze-hydraulic.
Izimiso zokuklama zezigxivizo ezihlanganisiwe zihlanganisa okulandelayo:
① Isilinganiso sokuminyanisa sesisonke senhlanganisela yophawu sinalwa ngokufanelekile ngokuya ngezakhiwo zezinto ezibonakalayo.Isimo samahhala somkhiqizo kanye ne-groove phakathi kwegebe, kodwa hhayi esikhulu kakhulu, ukuze unganyakazi ku-groove.
② indandatho yokuvala: uphawu oluyinhloko.Ubukhulu bayo abukwazi ukujiya kakhulu, ngokuvamile ku-2 ~ 5mm, kuya ngempahla ethile yokuvala;ububanzi bawo angeke bube banzi kakhulu, ububanzi bebhande lokuvala eliphumelelayo budlula inani elithile bungacatshangwa kanye ne-lubrication groove, ukugwema ukuvela kokungqubuzana okomile kanye nesenzakalo esinwabuzelayo.
③ i-elastomer: indima iwukuhlinzeka ngokuqhubekayo ukusekela ukuqinisekisa ukuthi inhlanganisela yokuvala umphumela wokuvala uphawu.Ngokusho kokuqina kwento, i-modulus of elasticity kanye nezinye izinga lokucindezelwa okufanele, ububanzi bayo nobubanzi be-groove ukushiya igebe elifanele phakathi.Qinisekisa ukuthi i-elastomer inesikhala esanele sokuhamba ngemva kokukhishwa.
④Indandatho yokugcina: indima iwukuqinisekisa ukuzinza kwendawo ye-elastomer ngemva kokulayisha emseleni, ukuze kuthuthukiswe ukuzinza kweringi yophawu iyonke.Kuhlanganiswe nendandatho yokuvala kanye nomklamo jikelele we-elastomer.
⑤ Indandatho yomhlahlandlela: Umsebenzi uwukuqondisa nokuqinisekisa ukusebenza okubushelelezi nokuzinzile kwepiston kusilinda, ukuvimbela izingxenye zensimbi ze-piston ukuthi zingathintani nombhobho wensimbi we-cylinder futhi zilimaze ubuso bombhobho wensimbi we-cylinder.Isakhiwo ngokuvamile samukela i-GFA /GST ejwayelekile.
