Mfundo zofunika kuziganizira
Valavu yothandizira ndi hydraulic pressure control valve, yomwe makamaka imagwira ntchito yochepetsera kupanikizika kosalekeza, kuwongolera kupanikizika, kutsitsa dongosolo ndi chitetezo chachitetezo pazida zama hydraulic. Mu kachulukidwe pampu throttling regulation dongosolo, kachulukidwe mpope amapereka otaya nthawi zonse, pamene kuthamanga kwa dongosolo kumawonjezeka, kufunikira kwa kutuluka kudzachepetsedwa, panthawiyi valve yothandizira imatsegulidwa, kotero kuti kuthamanga kwambiri kubwerera ku thanki, kuonetsetsa kuti kuthamanga kwa valve yolowera, ndiko kuti, kuthamanga kwa potulutsira pampu kumakhala kosasintha. Valve yothandizira imalumikizidwa motsatizana pamayendedwe obwerera mafuta, ndipo kukhazikika kwa magawo osunthira kumbuyo kwa valavu yothandizira kumawonjezeka. Ntchito yotsitsa ya dongosololi ndikulumikiza valavu ya solenoid ndi kayendedwe kakang'ono kamene kakusefukira pamndandanda pa doko lakutali la valve yothandizira. Pamene electromagnet yapatsidwa mphamvu, doko loyang'anira kutali la valve yothandizira limadutsa mu thanki yamafuta. Panthawiyi, pampu ya hydraulic imatsitsidwa ndipo valve yothandizira imagwiritsidwa ntchito ngati valavu yotsitsa. Chitetezo cha chitetezo ntchito, pamene dongosolo likugwira ntchito bwino, valavu imatsekedwa, pokhapokha ngati katunduyo akupitirira malire omwe atchulidwa, kusefukira kumatsegulidwa, ndipo chitetezo chochuluka chimachitidwa, kotero kuti kupanikizika kwa dongosolo sikuwonjezeka.
Komatsu excavator Ndi valavu ntchito mfundo
The ls valve of Komatsu excavator imatanthawuza valavu yoyendetsera kayendedwe ka madzi mu hydraulic system, yomwe imatha kulamulira kuthamanga ndi kuthamanga kwa madzi mu hydraulic system. Mu zofukula za Komatsu, mfundo yogwirira ntchito ya valavu ya 1s imaphatikizapo mbali ziwiri, zomwe ndi kuwongolera ndi kuwongolera kuthamanga.
1. Kuwongolera kuyenda
Phazi lowongolera kuthamanga limawongolera kutuluka kwamadzi mu hydraulic system posintha kutsegulira kwa valavu ya 1s. Pamene Komatsu excavator ayenera kusintha liwiro la hayidiroliki yamphamvu, madzi otaya akhoza lizilamuliridwa ndi kusintha kutsegula kwa valavu 1s, kuti tikwaniritse kulamulira liwiro la hayidiroliki yamphamvu. Valve ya ls imayang'anira malo otaya madzi posintha kusiyana pakati pa spool ndi mpando, potero kuwongolera kutuluka kwamadzimadzi.
2. Kuwongolera kupanikizika
Kuwongolera kwapanikizi kumatanthawuza kuwongolera kukakamiza kogwira ntchito kwa hydraulic system posintha kutengera kwa ls valve. M'mafukufuku a Komatsu, makina a hydraulic amafunika kukhala ndi mphamvu yogwira ntchito kuti atsimikizire kuti gawo lililonse la hydraulic lingagwire ntchito bwino. ls valavu imayang'anira kutayika kwamadzimadzi omwe akuyenda pakatikati pa valavu posintha kutsegula kwa dzenje lonyowa, kuti athe kuwongolera kuthamanga kwa dongosolo.
