Umlando omfushane wokuthuthukiswa kobuchwepheshe bonjiniyela bokutywina baseChina (I)
Umlando wokuthuthukiswa kwezimpawu zenjoloba nepulasitiki e-China mfushane kakhulu, lapho izwe lisungulwa, imboni yokuvala iraba nepulasitiki imane nje ingenalutho.Inkathi yegolide yangempela yemboni yenjoloba neyepulasitiki yaseChina ingemva kwezinguquko kanye nokuvuleka.Namuhla ngizokutshela ngomlando wokuthuthukiswa kobuchwepheshe bokuvalwa kobunjiniyela ngendikimba yezimpawu zenjoloba nepulasitiki eChina.
Okokuqala, isigaba sokuqala sobuchwepheshe bokufaka uphawu lobunjiniyela
Ngalesi sikhathi semikhiqizo yemishini yokwakha yaseChina ingcindezi yokusebenza yesistimu ye-hydraulic icishe ibe ngu-12-14MPa.uhlelo lokuvala olusetshenzisiwe olunezimpawu yilezi: uphawu lwenjoloba olumise okwe-0 (NBR);igobolondo lensimbi uphawu lwamafutha ajikelezayo esikhumba senkomo;insimbi kathayela ishumi likakhokho eziyishumi metal spring ekupheleni uphawu;ukupakisha kwe-asbestos;i-asbestos i-rubber eyishumi yokuvala i-gasket;Uphawu olumise okwe-V (isikhumba senkomo esiyishumi phenolic izinkuni zerabha eziyishumi);Uphawu olumise okwe-V (Indwangu yesiqeshana se-NBR eyishumi]: okuthambile kuzoba i-genus sealing gaskets nokunye.
Okwesibili, isigaba sokuqala sobuchwepheshe bokuvalwa kobunjiniyela
Ngalesi sikhathi ukukhiqizwa kwemikhiqizo eyinhloko yaseShayina yemishini yokwakha ingcindezi yokusebenza kwesistimu ye-hydraulic cishe i-14-3.5MPa.uhlelo lwayo lokuvala olusetshenziswa ezimpahleni zenjoloba kanye nezigxivizo zepulasitiki yizona eziyinhloko, ezisusa isikhumba senkomo, i-asbestos fibre kanye nensimbi ewuthayela izinsimbi eziyishumi zokugcina zikakhokho.Izinhlobo eziyinhloko D yilezi: uphawu olumise okwe-0 (NBR, FKM);isiseshi sika-D sika-chassis esinophawu lwamafutha antantayo (indandatho yensimbi eyomile enomfanekiso ongu-0);D iphakheji yangaphakathi ye-skeleton rotary oil seal Chuan BR, FKM, ZACM).Izigxivizo ezinyakazayo ze-Hydraulic nezomoya D ziyi-0-shaped seal (NBR, FKM);Indandatho yomjovo we-D eminyene emise okwe-U (NBR, AU, BU): Uphawu olumise okwe-V (indwangu yesemishi eliyishumi le-NBR);uphawu olumise okwenkomishi (indwangu yesemishi ye-NBR eyishumi), njll.
Kule minyaka eyi-10, ukuze kuhlangatshezwane nezidingo zentuthuko ezifana nemishini yokwakha, imishini yokubumba neyokucindezela, njll. kusetshenziswa ubuchwepheshe be-hydraulic obuphakathi nomfutho ophezulu, uMnyango Wezemishini wangaphambili wasungula isitshalo sokukhiqiza izinti zenjoloba eziyisikhombisa nepulasitiki.Ngaphezu kwalokho, ukuze kuthuthukiswe ukuthuthukiswa kobuchwepheshe bokuvala uphawu e-China, "iKomidi Likazwelonke Lobuchwepheshe Lokumisa I-Hydraulics kanye Ne-Pneumatics I kanye neKomidi Likazwelonke Lobuchwepheshe Lokulinganisa I-Hydraulics ne-Pneumatics Rubber kanye ne-Plastic Seals Standardization Sub-Technical Committee" (ehambisanayo kuya ku-ISO/TCI3/SC7 endala) yasungulwa ngo-1975 nango-1979, kanye ne-Institute of Friction Fluid (ehambisana ne-ISO/TCI3/SC7 yakudala) kanye ne-Friction Society Fluid Seals Sub-Technical Committee.
