valavu yoyendetsa valavu yoyendetsedwa ndi CBBA-LHN

Crane yamagalimoto imagwiritsidwa ntchito kwambiri, magalimoto opangira zinthu zambiri, otchuka pamsika wapadera wamagalimoto, zigawo zake zazikulu ndi chassis yagalimoto yapadera ndi crane yonyamula, kudzera pamayendedwe amakina monga matalikidwe, kukulitsa, kuzungulira, kukweza mpaka. kwaniritsani zochita zamakina agalimoto yamagalimoto, kudzera mumitundu yosiyanasiyana kuti mukwaniritse ntchito zokweza. Pali valavu yoyezera gawo mu hydraulic system ya crane, yomwe imatha kugwira ntchito yochepetsa liwiro pakugwa kwa crane, mkono wowonjezera ndi mkono wolumikizira, womwe ungapewe kutayika kwa kuwongolera komwe kumayang'ana chinthu cholemera. , ndi kupanga chinthu cholemera ndi mkono wonyamulira kukhala wokhazikika pamalo enaake mu danga.
Valavu yoyezera imatha kugwira ntchito yochepetsa liwiro mu crane: pomwe makina a crane kapena katundu akatsika, valavu yotsatizana mu valavu yolumikizira imatha kugwiritsa ntchito gawo lapakati kuti asunge kukhazikika kwamafuta akubwerera kwa silinda ya hydraulic, kotero kuti silinda ya hydraulic imakhala ndi kayendedwe ka yunifolomu, kuti ipeze liwiro lakugwa yunifolomu, dongosolo lokonzekera liyenera kumvetsera mfundo ziwiri: Choyamba, pofuna kupulumutsa ndalama, valavu yosavuta yowunika ndi valve yoyendera kunja yotuluka mkati. amagwiritsidwa ntchito m'malo mwa valve balance. Izi zili choncho chifukwa ngakhale kuti valavu yamagetsi imakhalanso yophatikizira valavu ya njira imodzi ndi valavu yowonongeka yamtundu wamtundu wotuluka kunja, valavu yotsatizana yawonjezera kasupe wawiri-wosanjikiza, mabowo otsekemera ndi zipangizo zina kuti apange valve core shock absorber. ; Chachiwiri ndi chakuti kayendetsedwe ka mafuta oyendetsa magetsi a valve balance iyenera kulumikizidwa motsatizana ndi valve throttle, kotero kuti spool zochita za valve yotsatizana ndi "zaulesi", ndipo liwiro lake silinasinthidwe chifukwa cha kusintha kwakung'ono kwa mphamvu yakunja.
