Kuti uvandudze hupenyu hwechisimbiso, kupesana kwekupokana kwechisimbiso chikuru kunoda kuve kwakaderera, izvo zvinoda firimu remafuta pane inotsvedza pamusoro pechisimbiso chikuru.Urwu huwandu hwema coefficients ekukweshera umo iyo firimu remafuta inogadzirwa inozivikanwa zvakare mune lubrication theory semafuta ekuzora.Muchikamu ichi, nzvimbo yekushanda yechisimbiso inosangana ne cylinder kana tsvimbo kuburikidza nefirimu yemafuta, apo chisimbiso chine hupenyu hurefu hwebasa pasina kupfeka, kunyange kana kufamba kwehama kuchiitika.Nechikonzero ichi, zvakakosha kugadzira yunifomu yekubata kumanikidza kugovera kuitira kuti firimu remafuta rakakwana rigone kugadzirwa panzvimbo inotsvedza.Izvi ndezvechokwadi kwete chete kune zvisimbiso zvakasanganiswa asi kune ese ma hydraulic seals.
Misimboti yekugadzira yekusanganisa zvisimbiso inosanganisira zvinotevera:
① Iyo yakazara yekumanikidza mwero weiyo musanganiswa chisimbiso inokosheswa zvakakodzera zvichienderana neiyo zvinhu zvivakwa.Mukaha pakati pechigadzirwa uye groove mune yakasununguka nyika yasara, asi kwete yakanyanya kukura kuti usazununguke mu groove.
②Kuvhara mhete:Main chisimbiso.Ukobvu hwayo haugone kuve hwakakora zvakanyanya, kazhinji mu2 ~ 5mm, neiyo chaiyo yekuisa chisimbiso zvinhu;hupamhi hwayo hahugoni kuva hwakafara zvikuru, iyo inoshanda chisimbiso bhendi upamhi inopfuura imwe kukosha inogona kutariswa kuwedzera lubrication groove, kudzivirira yakaoma kukweshera uye kukambaira chiitiko.
③Elastomer: basa nderekuenderera mberi nekupa rutsigiro kuti ive nechokwadi chekuisa chisimbiso chemusanganiswa chisimbiso.Maererano nezvinhu kuoma, elastic modulus, etc. kutora zvakakodzera compression mwero, upamhi hwayo uye upamhi groove kusiya akakodzera gap pakati.Ita shuwa kuti elastomer ine nzvimbo yakakwana yekufamba mushure me extrusion.
④ Chengetedza mhete: Basa nderekuona kugadzikana kwechinzvimbo che elastomer mushure mekupinda mugororo, kuitira kuvandudza kugadzikana kwese kwechisimbiso mhete.Yakasanganiswa nemhete yechisimbiso uye elastomer yakazara dhizaini.
⑤Kutungamira mhete: Basa ndere kutungamira uye kuve nechokwadi chekushanda kwakatsetseka uye kwakadzikama kwepiston mucylinder uye kudzivirira kukuvadzwa kwecylinder simbi pamusoro nekusangana pakati pepiston simbi uye cylinder simbi mbiya.Chimiro chacho chinowanzojairika GFA /GST.
