Imbali emfutshane yophuhliso lobuchwephesha bobunjineli bokutywina baseTshayina (I)
Imbali yophuhliso lwezitywina zeerabha kunye neplastiki eChina ifutshane kakhulu, xa ilizwe lasekwayo, i-rubber kunye neplastiki yokutywina imboni iyinto engenanto.Ubudala begolide bokwenyani beshishini lerabha kunye neplastiki laseTshayina lisemva kohlaziyo kunye nokuvula.Namhlanje ndiza kukuxelela ngembali yokuphuhliswa kobuchwephesha bokutywinwa kobunjineli kunye nomxholo we-rubber kunye neeplastiki zokutywinwa eChina.
Okokuqala, inqanaba lokuqala lobuchwephesha bokutywinwa kobunjineli
Ngeli xesha leemveliso zoomatshini bokwakha baseTshayina inkqubo yoxinzelelo lwehydraulic yokusebenza imalunga ne-12-14MPa.inkqubo yokutywina esetyenzisiweyo enamatywina ngala: 0-shaped rubber seal (NBR);iqokobhe lentsimbi isitywini seoli yenkomo;intsimbi etyatyiweyo intsimbi yesivalo ezilishumi intsimbi yokuphela kwetywina;ukupakisha i-asbestos;i-asbestos i-gasket yokutywina irabha ezilishumi;Isitywina esimilo engu-V (isikhumba senkomo ishumi leenkuni zerabha eline phenolic);Itywina elinemilo engu-V (i-NBR ishumi leclip Ilaphu]: ithambile iya kuba yi-gaskets yokutywina ye-genus njalo njalo.
Okwesibini, isigaba sokuqala sobuchwephesha bokutywinwa kobunjineli
Ngeli xesha imveliso yeemveliso eziphambili zaseTshayina zoomatshini bokwakha inkqubo yoxinzelelo lwehydraulic yokusebenza imalunga ne-14-3.5MPa.inkqubo yayo yokutywina esetyenziswa kwiitywina kwirabha kunye nezitywina zeplastiki zezona ziphambili, ukuphelisa ulusu lwenkomo, ifayibha yeasbestos kunye nentsimbi ebiyelweyo yezitywina ezilishumi zecork end.Iindidi eziphambili ze-D zezi: i-0-shaped seal (NBR, FKM);umkhandi D chassis ene-oyile edadayo yotywino (intsimbi yentsimbi eyomileyo enomfanekiso ongu-0);D iphakheji yangaphakathi skeleton rotary oil seal Chuan BR, FKM, ZACM).I-Hydraulic kunye ne-pneumatic reciprocating motion seals D ziyi-0-shaped seal (NBR, FKM);Iringi yenaliti ye-D eshinyeneyo eyenziwe ngu-U (NBR, AU, BU): Isitywina se-V (i-NBR ishumi lelaphu lesandwich);itywina elimilise okwekomityi (i-NBR ishumi lelaphu lesandwich), njl.
Kule minyaka eyi-10, ukuze kuhlangatyezwane neemfuno zophuhliso ezifana noomatshini bokwakha, oomatshini bokubumba kunye nokucinezela, njl.njl usebenzisa iteknoloji yoxinzelelo oluphakathi kunye noxinzelelo oluphezulu lwe-hydraulic, owayesakuba nguMphathiswa woShishino wamisela irabha esixhenxe yobuchwephesha kunye neplasitiki yokuvelisa imveliso.Ukongezelela, ukwenzela ukukhuthaza ukuphuhliswa kobuchwephesha bokutywinwa e-China, "iKomiti yeSizwe yezobuGcisa yoMgangatho we-Hydraulics kunye ne-Pneumatics I kunye neKomiti yeSizwe yezobuGcisa yoMgangatho we-Hydraulics kunye ne-Pneumatics Rubber kunye ne-Plastic Seals Standardization sub-Technical Committee" (ehambelanayo ukuya ISO/TCI3/SC7 endala) yasekwa ngo-1975 kunye 1979, kwakunye Institute of Friction Fluid (ehambelana ne-ISO/TCI3/SC7 endala) kunye neFriction Society Fluid Seals Sub-Technical Committee.
