U-ring ndiye chisindikizo chamafuta chomwe chimagwiritsidwa ntchito kwambiri mu masilinda a hydraulic, ndi mtundu wa seal milomo, kaya pisitoni kapena piston ndodo imatha kupeza kusindikiza kwabwino.Pansi pa kupanikizika kochepa, U-ring imasindikizidwa kokha ndi kusokoneza kwa milomo, ndipo kukangana kumakhala kochepa chifukwa cha malo ang'onoang'ono okhudzana.Ndi kuwonjezereka kwa kupanikizika, kuchuluka kwa kusinthika kwa milomo kumawonjezeka, kugwedezeka, kuponderezana ndi kupindika kumawonjezeka, kuponderezana kwa radial kwa U-ring kumakhala kwakukulu, ndipo kutalika kwa kukhudzana ndi chisindikizo kumapitirira kuwonjezeka mpaka Utali wonse wa axial wa U-ring umagwirizana ndi malo osindikizira, kuti atsimikizire kusindikizidwa bwino pansi pa kupanikizika kwakukulu.
Kuyika ndondomeko
Pamene pisitoni imasonkhanitsidwa ndi mphete yosindikizira yooneka ngati U, m'pofunika kugwiritsa ntchito choyikapo, chomwe ndi cone.Kuzama kwa mutu waukulu kumakhala kokulirapo kuposa kutalika kwa kumapeto kwa pisitoni yosindikizira.Ndi bwino kukhala ndi kutalika pang'ono kwa silinda, ndipo ngodya yakuthwa iyenera kukhala yozungulira ndipo roughness iyenera kukhala yosachepera 0,8.Pistoni ndi zidazo zimayikidwa mokhazikika, choyikacho chimakutidwa ndi batala, U-ring imatenthedwa mpaka madigiri 55 mumafuta, kenako yokutidwa ndi mafuta, ndikukankhira motsatira chisindikizo cha piston.Bowo lotsogolera mkati mwa mphete yosindikizira yooneka ngati U ndi yovuta kwambiri, chowongolera dzanja choyamba pamasitepe onse ozungulira, bola ngati chozungulira pang'ono, osapachika dzanja pamzere, ndiyeno kuyeretsa, dzenje lamkati litakutidwa ndi. batala, mphete yosindikizira imatenthedwanso mpaka madigiri 55 mu mafuta, ndiyeno yokutidwa ndi batala, dzanja lofinyidwa mu dzenje lachiwongolero muzitsulo zosindikizira, mawondo akuluakulu ndi abwino kuyikapo, mphete yosindikizayo imalowa mkati mwa mtima, mukhoza kuyikapo. .
