Yogwiritsidwa ntchito ku excavator hydraulic relief valve 723-40-50100

Mfundo yogwira ntchito ndi:

Kuthamanga kwa kasupe kumasinthidwa ndipo kupanikizika kwa mafuta a hydraulic kumayendetsedwa. Monga momwe tikuonera pachithunzichi: pamene kupanikizika kwa mafuta a hydraulic kuli kochepa kuposa kukakamiza kofunikira pa ntchito, spool imapanikizidwa ndi kasupe polowera mafuta a hydraulic. Pamene kupanikizika kwa mafuta a hydraulic kupitirira kukakamizidwa kovomerezeka kwa ntchito yake, ndiye kuti, pamene kupanikizika kuli kwakukulu kuposa kuthamanga kwa kasupe, spool imathamangitsidwa ndi mafuta a hydraulic, ndipo mafuta a hydraulic amalowa mkati, amatuluka kuchokera pakamwa kumanja. njira yosonyezedwa, ndi kubwerera ku thanki. Kuchuluka kwa mafuta a hydraulic, kumapangitsa kuti spool ikhale yokwera kwambiri ndi mafuta a hydraulic, ndipo mafuta a hydraulic amabwereranso ku thanki kudzera mu valve yothandizira. Ngati kupanikizika kwa mafuta a hydraulic kuli kochepa kapena kofanana ndi kuthamanga kwa masika, spool imagwa ndikusindikiza mafuta a hydraulic mafuta. Chifukwa kuthamanga kwamafuta a hydraulic pampu yamafuta kumakhazikika, ndipo kukakamiza kwamafuta a hydraulic a silinda yogwira ntchito kumakhala kocheperako kuposa kukakamiza kwamafuta a hydraulic pampu yamafuta, nthawi zonse pamakhala mafuta ena a hydraulic obwerera ku thanki kuchokera ku valavu yothandizira pakugwira ntchito yanthawi zonse kuti mukhalebe ndi mphamvu yogwira ntchito ya silinda ya hydraulic ndi ntchito yabwinobwino. Zitha kuwoneka kuti ntchito ya valavu yothandizira ndikuletsa kuthamanga kwa mafuta a hydraulic mu hydraulic system kuti asapitirire katundu wovomerezeka ndikuchita ntchito yoteteza chitetezo.
