Ntchito yaikulu ya valve yothandizira

Kuthamanga kwanthawi zonse: mu dongosolo la quantitative pump throttling regulation, pampu yochulukira 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) .

Mphamvu yolimbitsa mphamvu: Valve yothandizira imalumikizidwa mndandanda pamayendedwe obwerera mafuta, valavu yopumira imatulutsa kupanikizika kumbuyo, ndipo kukhazikika kwa magawo osuntha kumawonjezeka.

Ntchito yotsitsa dongosolo: doko loyang'anira kutali la valve yothandizira limalumikizidwa ndi valavu ya solenoid yokhala ndi kusefukira kwakung'ono. Pamene electromagnet yapatsidwa mphamvu, doko loyang'anira kutali la valve yothandizira limadutsa mu thanki yamafuta, ndipo pampu ya hydraulic imatsitsidwa panthawiyi. Valve yothandizira tsopano imagwiritsidwa ntchito ngati valavu yotsitsa.

Chitetezo cha chitetezo: Pamene dongosolo likugwira ntchito bwino, valve imatsekedwa. Pokhapokha pamene katunduyo adutsa malire omwe atchulidwa (kupanikizika kwa dongosolo kumadutsa kupanikizika kokhazikitsidwa), kusefukira kumatsegulidwa kuti atetezedwe mochulukira, kotero kuti kupanikizika kwa dongosolo sikulinso kuwonjezeka (kawirikawiri kupanikizika kwa valve yothandizira ndi 10% mpaka 20% apamwamba kuposa kupanikizika kwakukulu kwa ntchito ya dongosolo).

Zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala: ngati valavu yotsitsa, monga chowongolera chakutali, monga valavu yothamanga kwambiri komanso yotsika kwambiri, monga valve yotsatizana, yomwe imagwiritsidwa ntchito popanga kupanikizika kumbuyo (chingwe pamayendedwe obwerera mafuta).
