Ma hydraulic balance valve Excavator hydraulic cylinder valve pachimake NFED-LHN

Pamene valve yothandizira ambiri ikugwira ntchito, imasinthidwa kwathunthu ndikuyendetsedwa ndi kuthamanga kwa masika. Ikhoza kusintha kuthamanga kwa mafuta a hydraulic ndi kukakamiza. Kawirikawiri, ngati kupanikizika kwa mafuta a hydraulic kuli kochepa kusiyana ndi kukakamiza kofunikira pa ntchitoyo, spool imakanizidwa ndi kasupe panthawiyi ndipo ili mu hydraulic oil flow inlet attachment. Koma pamene kupanikizika kwa mafuta a hydraulic kumakhala kwakukulu kuposa kukakamizidwa kovomerezeka mu ntchito, mwa kuyankhula kwina, pamene kupanikizika kuli kwakukulu kuposa kasupe, spool mwachibadwa amakankhidwa ndi mafuta a hydraulic, ndipo mafuta a hydraulic adzalowa mkati ndi kunja. kupita ku tanki.

Pamene kupanikizika kwa mafuta a hydraulic kumawonjezeka pang'onopang'ono, spool nayonso imatsekedwa pang'onopang'ono. . Panthawiyi, mafuta a hydraulic amayenda kudzera mu valve yothandizira kupita ku tanki yoyenera kuyenda pang'onopang'ono, pamene kupanikizika kwa mafuta a hydraulic kumachepetsedwa kukhala kofanana kapena kucheperapo kusiyana ndi kuthamanga kwa masika, spool idzagwa mwachibadwa kuti isindikize cholowera chofanana. mafuta a hydraulic.
Kutulutsa kwamafuta a hydraulic ndi pampu yamafuta ambiri kumakhala ndi mphamvu yokhazikika, ndipo kukakamiza kofananira kwamafuta a hydraulic omwe amagwiritsidwa ntchito ndi silinda yogwira ntchito nthawi zambiri kumakhala kochepa kwambiri kuposa kutulutsa kwapampu yamafuta. Panthawiyi, tidzawona kuti pamene ntchitoyo ili yachibadwa, padzakhala mafuta a hydraulic akuyenda mu thanki kupyolera mu chipangizo cha valve yothandizira. Izi zitha kuwonetsetsa kuti silinda ya hydraulic ili ndi mphamvu yogwira ntchito.
