Screw cartridge valve flow control valve LFR10-2A-K

Valavu yolipirira kuthamanga

Malingana ndi malo a valve compensation compensation mu dera lonse la hydraulic, dongosolo loyendetsa chiwongoladzanja chowongolera katundu lingathenso kugawidwa mu pre-valve pressure compensation load-sensitive system ndi post-valve pressure compensation load-sensitive system. Chiwongoladzanja cha pre-valve chimatanthawuza kuti valavu yochepetsera kupanikizika imakonzedwa pakati pa pampu ya mafuta ndi valavu yolamulira, ndipo kubwezera pambuyo pa valve kumatanthawuza kuti valavu yolipirira mphamvu imakonzedwa pakati pa valve yolamulira ndi actuator. Malipiro a pambuyo pa valve ndi apamwamba kwambiri kuposa chiwongoladzanja cha valve isanayambe, makamaka pakakhala kusakwanira kwa mafuta a pampu. Ngati mafuta a pampu sakukwanira, valavu yaikulu yomwe imalipidwa pamaso pa valavu idzapangitsa kuti pakhale kutuluka kwa katundu wopepuka komanso kutsika pang'ono ku katundu wolemetsa, ndiko kuti, katundu wopepuka amayenda mofulumira, ndipo actuator iliyonse ili kunja kwa sync. pamene ntchito yapawiri ikuchitika. Komabe, pambuyo-valve chipukuta misozi alibe vuto ili, izo kugawira otaya operekedwa ndi mpope mu gawo, ndi synchronize zinthu zonse actuating pa pawiri zochita. Dongosolo lozindikira katundu limagawidwa kukhala chipukuta misozi chisanachitike komanso chipukuta misozi. Pamene katundu awiri kapena kuposerapo akugwira ntchito nthawi imodzi, ngati kuyenda koperekedwa ndi mpope waukulu ndikokwanira kuti akwaniritse kayendedwe kamene kakufunika ndi dongosolo, ntchito za pre-valve compensation ndi post-valve compensation ndizofanana. Ngati kuyenda koperekedwa ndi mpope waukulu sikungathe kukumana ndi kayendedwe kofunikira ndi dongosolo, malipiro asanayambe valavu ali motere: kutuluka kwa mpope waukulu poyamba kumapereka kutuluka kwa katundu ndi katundu wochepa, ndiyeno amapereka kutuluka. ku katundu wina pamene zofunikira zoyenda za katundu ndi katundu wochepa zimakwaniritsidwa; Mkhalidwe wa chipukuta misozi pambuyo pa valve ndi: kuchepetsa kutuluka kwa katundu aliyense poyerekeza ndi nthawi yomweyi ya chaka chatha (kutsegula kwa valve) kuti akwaniritse zotsatira za mgwirizano. Ndiko kuti, pamene kutuluka koperekedwa ndi mpope waukulu sikungathe kukumana ndi kayendedwe kofunikira ndi dongosolo, kugawa kwa kayendedwe kamene kamalipidwa kumapereka chiwongoladzanja chisanakhale chokhudzana ndi katundu, pamene kugawa kwapakati kumaperekedwa pambuyo poti valve sichikugwirizana ndi katundu, koma kokha. zokhudzana ndi kuchuluka kwa kutsegula kwa valve yaikulu.
