Mbiri yachidule ya chitukuko chaukadaulo waukadaulo waku China (I)

Mbiri ya chitukuko cha zisindikizo za mphira ndi pulasitiki ku China ndi yochepa kwambiri, pamene dzikoli linakhazikitsidwa, makampani osindikiza mphira ndi pulasitiki ndi opanda kanthu.M'badwo weniweni wamakampani opanga mphira ndi pulasitiki ku China ndi pambuyo pa kukonzanso ndikutsegula.Lero ndikuwuzani mbiri ya chitukuko chaukadaulo wosindikiza uinjiniya ndi mutu wa zisindikizo za rabara ndi pulasitiki ku China.

Choyamba, gawo loyambira laukadaulo wosindikiza uinjiniya
Panthawi imeneyi ya makina omanga aku China opangira ma hydraulic system akugwira ntchito pafupifupi 12-14MPa.makina osindikizira omwe amagwiritsidwa ntchito ndi zisindikizo ndi awa: 0-woboola pakati mphira chisindikizo (NBR);chipolopolo chachitsulo chisindikizo cha mafuta a chikopa cha ng'ombe;malata khumi Nkhata Bay khumi zitsulo kasupe mapeto chisindikizo;katundu wa asbestos;asibesitosi khumi mphira kusindikiza gasket;Chisindikizo chooneka ngati V (chikopa cha ng'ombe khumi phenolic nkhuni za rabara);Chisindikizo chooneka ngati V (NBR khumi kopanira Nsalu]: zofewa zidzakhala genus kusindikiza gaskets ndi zina zotero.
 
Chachiwiri, gawo loyambira laukadaulo wosindikiza uinjiniya
Panthawiyi kupanga zinthu zazikulu zaku China zamakina omanga makina opangira ma hydraulic system kugwira ntchito kumakhala pafupifupi 14-3.5MPa.makina ake osindikizira omwe amagwiritsidwa ntchito mu zisindikizo ku mphira ndi zisindikizo za pulasitiki ndizo zikuluzikulu, kuchotsa zikopa za ng'ombe, ulusi wa asbestos ndi zitsulo zamalata khumi zosindikizira za cork mapeto.Mitundu yayikulu D ndi: chisindikizo chofanana ndi 0 (NBR, FKM);chokwawa D chassis chokhala ndi chisindikizo chamafuta oyandama (chifanizo chachitsulo chowuma chooneka ngati 0);D mkati mwa phukusi la mafupa ozungulira mafuta a Chuan BR, FKM, ZACM).Zisindikizo za Hydraulic ndi pneumatic reciprocating D ndi chisindikizo chooneka ngati 0 (NBR, FKM);Mphete ya jekeseni ya D yooneka ngati U (NBR, AU, BU): Chisindikizo chooneka ngati V (NBR sangweji khumi nsalu);chisindikizo chooneka ngati chikho (NBR ten sangweji nsalu), etc.

M'zaka 10, kuti akwaniritse zosowa za chitukuko monga makina yomanga, forging ndi kukanikiza makina, etc. ntchito sing'anga ndi mkulu kuthamanga hayidiroliki luso, Unduna wakale wa Machinery anakhazikitsa asanu akatswiri mphira ndi pulasitiki zisindikizo kupanga chomera.Kuphatikiza apo, pofuna kulimbikitsa chitukuko chaukadaulo wosindikiza ku China, "National Technical Committee for Standardization of Hydraulics and Pneumatics I ndi National Technical Committee for Standardization of Hydraulics and Pneumatics Rubber and Plastic Seals Standardization Sub-Technical Committee" (yogwirizana ndi ku ISO/TCI3/SC7 yakale) idakhazikitsidwa mu 1975 ndi 1979, komanso Institute of Friction Fluid (yogwirizana ndi ISO/TCI3/SC7 yakale) ndi Friction Society Fluid Seals Sub-Technical Committee.
