Oyenera PC400-6 mfuti 723-90-61400 valve thandizo

Kumene kuli valavu yotsitsimula ya excavator

Pamwamba pa valavu yoperekera, mawonekedwe omwewo. Mukayang'ana papampu ya hydraulic pamwambapa, muwona kuti pali mapaipi awiri ofanana kukula kwake, adzakhala okulirapo kuposa mapaipi ena, mapaipi awiriwa ali ku valavu yogawa, valavu yogawa pamwamba pa valavu yolamulira yomwe ili ndi mapaipi awiriwa. ndi valve yothandizira. Valve yothandizira imakhala ndi mphamvu yowonjezereka yowonjezereka: mu dongosolo la quantitative pump throttling regulation, pampu yowonjezera imapereka kuthamanga kosalekeza. Pamene kupanikizika kwa dongosolo kumawonjezeka, kufunikira kothamanga kudzachepa. Panthawiyi, valve yothandizira imatsegulidwa, kotero kuti kutuluka kwakukulu kumabwereranso ku thanki, kuonetsetsa kuti mpweya wotsekemera wa valve, ndiko kuti, kuthamanga kwa mpweya wa pampu kumakhala kosalekeza (doko la valve nthawi zambiri limatsegulidwa ndi kusinthasintha kwa kuthamanga) .

Ntchito ya valve yothandizira

Spillover zotsatira. Valve yothamanga imatha kusintha ndikuwongolera kuyenda mu zida za hydraulic pomwe pampu yochulukira ikupereka mafuta. Ntchito yachitetezo chachitetezo. Pewani ngozi zobwera chifukwa cha kuchuluka kwa zida zama hydraulic ndi zida zamakina. Amagwiritsidwa ntchito ngati valve yotulutsa. Valve yoteteza oyendetsa ndege ndi ma valve awiri a solenoid awiri amagwiritsidwa ntchito palimodzi ndipo angagwiritsidwe ntchito ngati njira yotsitsa. Mavavu owongolera kutali komanso kuthamanga kwapakati. Kuwongolera kwapamwamba ndi kotsika kosiyanasiyana. Amagwiritsidwa ntchito ngati valve yotsatizana.

Ngati valavu yothandizira ya chokumbayo yathyoledwa, idzakhudza zomwe zikuchitika, ndipo kuthamanga kwa mafuta sikungapitirire ku chipinda chapamwamba cha valavu yaikulu ndi chipinda chakutsogolo cha valve yoyendetsa ndege, ndipo valavu yoyendetsa ndege idzataya mphamvu yake yolamulira. kuthamanga kwa valve yaikulu; Chifukwa palibe kupanikizika kwa mafuta m'chipinda chapamwamba cha valavu yaikulu ndipo mphamvu ya masika ndi yaying'ono kwambiri, valavu yaikulu imakhala valavu yothandizira mwachindunji ndi mphamvu yaing'ono ya masika. Pamene kupanikizika kwa chipinda cholowetsa mafuta kumakhala kochepa kwambiri, valavu yaikulu idzatsegula kusefukira, ndipo dongosololi silingathe kukhazikitsa kupanikizika.
