Ifanele izincedisi zomlayishi we-excavator hydraulic proportional valve RE177539

Usenokungazi kakhulu malunga neevalvu zokhuseleko, kodwa xa kufikwa kwi-valufa (i-overflow) ye-valve, i-oil port overflow valves okanye imipu yesibini, unokuba nombono. Ezinye iingxaki eziqhelekileyo ze-excavators zibangelwa ukusilela kweevalve zokhuseleko, ezifana nesantya esicothayo, ubuthathaka, ukugqabhuka kombhobho okanye ukuqhuma kombhobho we-hydraulic, ukugoba kwe-cylinder lever njalo njalo. Ngaphandle kokuthetha okuninzi, lo mzalwana ulandelayo wokumba uya kukunika intshayelelo eneenkcukacha kwisisombululo sevalve yokhuseleko kunye nokungaphumeleli kwayo, ndiyakholelwa ukuba uya kuba ugcwele isivuno.
Ivalve yokunceda ifakwe kwi-valve yokulawula ephambili (umhambisi) kwicala lesiqu sokusebenza. Ngenkangeleko, ivalve yokukhulula i-cylindrical kwaye ifana kakhulu nevalve yokunceda. Umahluko ngumsonto wohlengahlengiso phezulu. Ivalve yokhuseleko inomsonto omnye kwaye ivalve yoncedo ephambili inemisonto emibini. Kwinqanaba loxinzelelo loxinzelelo, i-valve yokukhusela i-valve iphezulu kune-pressure setpoint ye-valve enkulu yokunceda.
Kwiimeko eziqhelekileyo, i-valve yokhuseleko ayithathi nxaxheba emsebenzini, ngoko ke umlinganiselo woxinzelelo lwe-valve yokhuseleko lukhethekileyo kwaye awukwazi ukulinganiswa ngokuthe ngqo ngesixhobo. Uxinzelelo lwe-valve enkulu yokunceda kufuneka lunyuswe kwangaphambili kwaye lunokulinganiswa kuphela emva kokuba luphezulu kunexabiso loxinzelelo lwevalve yokhuseleko.
