R210-7 R220-3 I-valve yokusiza i-Excavator XJBN-00653 hydraulic valve

Ngemva kokuba i-injector ifakwe ekhanda le-cylinder, i-O-ring ephakathi emasongweni amathathu e-O ihlukanisa umzila wamafutha ekhanda le-cylinder endaweni yokungena kawoyela kanye nendlela yokubuyisela uwoyela (ingxenye engaphezulu yiphaseji lokubuyisela uwoyela). Ngenxa yokuthi umfutho kawoyela wephaseji lokungena uwoyela uphakeme kunalowo wephaseji lokubuyisela uwoyela, lapho indandatho ye-O emaphakathi iphukile, amafutha ephaseji lokungena likawoyela azovuza emgudwini wokubuyisela uwoyela, ngaleyo ndlela andise ingcindezi emafutheni. buyisela iphaseji. Lapho ukuvala shaqa kucishiwe, ingcindezi ephaseji likawoyela elibuyayo izobuyiselwa endaweni yokungena kawoyela, ukuze ingcindezi kawoyela ngaphambi komgodi wokulinganisa umjovo ingancishiswa ngesikhathi ishisa ingcindezi kawoyela, okuholela ekuphumeni kobunzima. . Ubukhulu bomonakalo we-O-ring buyahlukahluka ngokuya kwesikhathi eside nesifushane somlilo. Ngemuva kokuthi iphutha lenzekile, kunzima ukucacisa ukuthi iyiphi i-cylinder ye-injector middle O-ring eyonakele, futhi kuyadingeka ukukhipha kancane kancane i-injector ukuze ihlolwe kuze kutholakale imbangela. Lapho ushintsha i-O-ring eyonakele, i-O-ring kufanele ifakwe ngendlela efanele ku-injector groove futhi ayikwazi ukusonteka; Kufanele igcotshwe ngamafutha ngaphambi kokulayisha ikhanda lesilinda; Njengoba i-injector ikhishwa futhi ilayishwa kabusha, ngokuvamile, uma singekho isilinganiso esiphephe kakhulu, ukushaywa kwe-plunger komjovo kufanele kulungiswe kabusha.
