Nhoroondo pfupi yekuvandudzwa kweChina yekuisa chisimbiso engineering tekinoroji (I)
Nhoroondo yekuvandudzwa kwerabha uye zvisimbiso zvepurasitiki muChina ipfupi kwazvo, apo nyika yakavambwa, indasitiri yekuisa chisimbiso yerabha nepurasitiki inongova isina chinhu.Iyo chaiyo yegoridhe zera reChina indasitiri yerabha nepurasitiki iri mushure mekugadzirisa nekuvhura.Nhasi ini ndichakuudza nezve nhoroondo yekuvandudzwa kweinjiniya yekuisa chisimbiso tekinoroji ine dingindira rerabha uye epurasitiki zvisimbiso muChina.
Chekutanga, nhanho yekutanga yeinjiniya yekuisa chisimbiso tekinoroji
Munguva ino yeChina yekuvaka michina zvigadzirwa hydraulic system inoshanda kumanikidza ingangoita 12-14MPa.yakashandiswa sealing system ine zvisimbiso ndezvi: 0-shaped rubber seal (NBR);simbi shell a cowde rotary mafuta chisimbiso;marata gumi koki gumi simbi simbi chitubu chisimbiso;asbestos kurongedza;asbestos gumi rubber sealing gasket;Chisimbiso chakaumbwa neV (dehwe remombe gumi phenolic ten rubber wood);V-yakaita chisimbiso (NBR gumi clip Fabric]: yakapfava ichave iyo genus yekuisa chisimbiso gaskets uye zvichingodaro.
Chechipiri, chikamu chekutanga cheinjiniya yekuisa chisimbiso tekinoroji
Munguva ino kugadzirwa kweChina chikuru zvigadzirwa zvekuvaka muchina hydraulic system inoshanda kumanikidza ingangoita 14-3.5MPa.hurongwa hwayo hwekuisa chisimbiso hunoshandiswa muzvisimbiso kune rabha uye zvisimbiso zvepurasitiki ndizvo zvakanyanya, kubvisa dehwe remombe, asbestos faibha uye simbi ine makora gumi ekupedzisira zvisimbiso.Mhando huru D ndeiyi: 0-yakaumbwa chisimbiso (NBR, FKM);crawler D chassis ine mafuta anoyangarara chisimbiso (simbi mhete yakaoma 0-yakaita mufananidzo);D yemukati pasuru skeleton rotary mafuta chisimbiso Chuan BR, FKM, ZACM).Hydraulic uye pneumatic reciprocating inofamba zvisimbiso D zviri 0-shaped chisimbiso (NBR, FKM);U-shaped dense D jekiseni mhete (NBR, AU, BU): V-yakaita chisimbiso (NBR gumi sandwich fabric);kapu-yakaita chisimbiso (NBR gumi sandwich jira), nezvimwewo.
Mumakore gumi aya, kuitira kuzadzisa zvinodiwa zvekusimudzira zvakadai semichina yekuvaka, yekufogisa nekutsikirira michini, nezvimwewo vachishandisa michina yepakati nepamusoro yehydraulic tekinoroji, yaimbova Ministry of Machinery yakamisa nomwe nyanzvi rabha uye epurasitiki zvisimbiso kugadzira chirimwa.Pamusoro pezvo, kuitira kusimudzira kusimudzira tekinoroji yekuisa chisimbiso muChina, iyo "National Technical Committee for Standardization yeHydraulics uye Pneumatics I uye National technical Committee for Standardization yeHydraulics uye Pneumatics Rubber uye Plastic Seals Standardization Sub-Technical Committee" (inoenderana. kune yekare ISO/TCI3/SC7) yakaumbwa muna 1975 uye 1979, pamwe neInstitute of Friction Fluid (inoenderana neiyo yekare ISO/TCI3/SC7) uye Friction Society Fluid Seals Sub-Technical Committee.
