Ngesikhathi sokusebenzisa i-umshini we-polyurethane foam, ngezinye izikhathi ngenxa yokusetshenziswa okungafanele ngu-opharetha noma ezinye izizathu, ezinye izingxenye zemishini ngokwayo zinezinkinga, okuholela ekuvaleni kwemishini, njengokuthi: ikhanda lokuxuba livinjiwe, i-valve ephezulu nephansi yokubuyisela emuva angikwazi ukuvala lezi. izinkinga, nolwazi lwangaphambilini luphinde lwakutshela mayelana nezixazululo zalezi zinkinga.Namuhla, ngizokutshela ukuthi yini ebangela ukushintshashintsha kwengcindezi nokucindezela okunganele kwesiteshi se-hydraulic?

1. Ukushintshashintsha kwengcindezi esiteshini samanzi abandayo Sivame ukuhlangana nokuguquguquka kwengcindezi okuhlukahlukene okuhambisana nokuguquguquka okungaphezulu naphansi.Lokhu kungenxa yokuthi isikhwama somoya se-accumulator siphukile noma umfutho we-nitrogen mncane kakhulu.Singashintsha i-nitrogen, egcwele i-nitrogen.Qaphela ukuthi umfutho we-nitrogen awukwazi ukuba phezulu kakhulu noma uphansi kakhulu, futhi ingcindezi ingafinyelela ku-100 MPa.

2. Umfutho wesiteshi se-hydraulic awuphezulu.Uma singekho isihlungi embobeni yokumunca yepompo ye-hydraulic engcole kakhulu, iphampu ngeke ikwazi ukumunca uwoyela.Ngeke nje ukucindezela kwamafutha kube okuphansi, kodwa ukugqoka kwepompo kuzophinde kusheshiswe.Ngakho-ke, kufanele kwenzeke ukuhlanza isihlungi somoya njalo.isici esisebenzayo.Ukwenyuka kwengcindezi ephansi kuhlotshaniswa nokugqoka amaphampu nama-valve okusiza.Ngenxa yezinkinga zokuklama nokuhlaziya ukwakheka kwezwe lami kwezomnotho nezenhlalo, iphampu yegiya esetshenziswayo ijwayele ukuguga, futhi kufanele siyishintshe kaningi uma idinga ukuthuthukiswa.I-valve yesiphethu sokuphepha ijwayele ukukhathala ngesikhathi sokusetshenziswa kwezimali ezinkulu futhi kufanele ilungiswe njalo ukuze kuvinjelwe ukuvuza kwengcindezi.
