Kukho izizathu ezine eziqhelekileyo zokungaphumeleli kweamatywina erabha: iimpazamo zoyilo, iimpazamo zokukhetha izinto, imiba yomgangatho wetywina, kunye nokusetyenziswa ngendlela engafanelekanga.
1. Iimpazamo zoyilo zidla ngokubangelwa ngabaqulunqi abangenakuqonda ngokwaneleyo imveliso.
Ngokomzekelo, uqikelelo olunganelanga loxinzelelo oluthwalwa yinto yokutywinwa, ukuqonda okungalunganga kokusasazwa koxinzelelo loqhagamshelwano kwindawo yokutywinwa, kunye noyilo olungenangqiqo lwe-groove yokubeka into yokutywina.Uhlalutyo lwento egqityiweyo (i-FEA) isoloko isetyenziselwa ukuncedisa kuyilo kunye nohlalutyo lokungaphumeleli kweamatywina.
2. Impazamo yokukhetha izinto eziphathekayo
Izinto eziqhelekileyo zokutywinwa kweerubha ziquka i-EPDM, i-NBR, i-VMQ, i-FKM, kunye ne-CR.Ezi rubber zineempawu ezahlukeneyo kunye nokusetyenziswa.Ukukhethwa kwezinto eziphathekayo kufuneka kuthathelwe ingqalelo kwiinkalo ezininzi, ezifana nokushisa kokusetyenziswa, nokuba izinto eziphathekayo zichasene ne-medium, ubunzima bezinto eziphathekayo, ukunyanzeliswa kwe-deformation esisigxina, kunye nokuxhatshazwa kokugqoka.
Iimpazamo zokukhetha izinto eziphathekayo zihlala zibangelwa ngabaqulunqi abangaqhelananga nokusebenza kwezinto ezahlukeneyo.Umthengisi we-rubber onamava angabonisa imiba yokukhethwa kwezinto ezibonakalayo kwasekuqaleni.
3. Umgangatho wetywina
Umgangatho wemveliso yamatywina unxulumene ngokusondeleyo nokuthembeka kwemveliso yokugqibela.Iingxaki eziqhelekileyo zibandakanya umgangatho ongazinzanga wezinto eziluhlaza, ukondla okungafanelekanga kwezinto eziphathekayo ngexesha lokuxuba i-rubber, ukugcinwa okungafanelekanga kwezinto eziluhlaza okanye i-rubber edibeneyo (ukungcola komnqamlezo), ukuxuba ukungalingani kwezinto zerabha, iimeko ezingafanelekanga ze-vulcanization (ubushushu, ixesha, uxinzelelo, njl. ukugcinwa okungafanelekanga kweemveliso zokutywinwa, kunye nokusetyenziswa okungafanelekanga kweembumba.Le miba idla ngokubandakanya ulawulo lomgangatho kwinkqubo yemveliso.Iqela lokuodola kufuneka lenze uhlolo oluninzi, uphando, kunye novavanyo lwemveliso xa ukhetha umenzi wecandelo lokutywina.Ngexesha lenkqubo yokubonelela, umenzi wetywina unokuphinda afuneke ukuba anike ingxelo yokuhlola eyinyani nechanekileyo.
4. Ukusetyenziswa ngokungafanelekanga kwezitywina
Isitywina esilungileyo, ukuba sisetyenziswe ngokungafanelekanga, sinokubangela ukuba yonke imveliso ingaphumeleli, njengokusetyenziswa kakubi kweoli yokuthambisa.
Enye ingxaki eqhelekileyo ziimpazamo zokufakela.Ngokomzekelo, ukuphazamiseka kwenzeka ngexesha lenkqubo yendibano ye-O-ring;Ukunyanzeliswa okungalinganiyo kwento yokutywinwa ngenxa yofakelo olungafanelekanga;Ukuthambisa okungonelanga kwezitywina kunye nezinye iimpazamo.Ukuba ezi ziphoso zibangelwa ngumenzi wezitywina, ngoko oku kuthathwa njengombandela womgangatho wokuvelisa
