Ntchito ya valve yothandizira

1, kukhathamiritsa kosalekeza kumachulukirachulukira: mu kachulukidwe pampu yowongolera kachulukidwe, pampu yochulukira imapereka kuyenda kosalekeza. Pamene kupanikizika kwa dongosolo kumachepetsedwa, kufunikira kothamanga kudzachepetsedwa. 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 kwamphamvu) .

2, mphamvu yowongolera mphamvu: valavu yothandizira imalumikizidwa motsatizana pa chitoliro chobwerera, valavu yopumira imapanga kupanikizika kumbuyo, ndipo magawo osuntha amawongolera kusalala.

Zochita zokondera kachitidwe: doko loyang'anira kutali la valve yothandizira limalumikizidwa ndi valavu ya solenoid yokhala ndi kusefukira kwakung'ono. Pamene maukonde a electromagnetic amayendetsedwa, doko loyang'anira kutali la valavu yothandizira limadutsa thanki yamafuta, ndipo pampu ya hydraulic imasinthidwa pakadali pano. Valve yothandizira tsopano imagwiritsidwa ntchito ngati valavu yobwerera.

3, chitetezo chachitetezo: Pamene dongosolo likugwira ntchito bwino, valavu ya mpira imazimitsidwa. Pokhapokha pamene katunduyo akudutsa malire omwe atchulidwa (kupanikizika kwa dongosolo kumadutsa kupanikizika kokhazikika), kusefukira kumatsegulidwa kuti atetezedwe kwa gawo, kotero kuti kupanikizika kwa dongosolo sikulinso kuwonjezeka (kawirikawiri, kupanikizika kwa valve yothandizira ndi 10% 20% apamwamba kuposa kuthamanga kwambiri kwa dongosolo).

4, ntchito yogwiritsira ntchito nthawi zambiri imakhala: ngati valve yobwezeretsa, monga chowongolera chakutali, monga valavu yothamanga kwambiri komanso yotsika kwambiri, monga valve yotsatizana, yoyenera kupanga kupanikizika kumbuyo (chingwe pa chitoliro chobwerera).

Vavu yothandizira nthawi zambiri imakhala ndi zida ziwiri: 1, valavu yothandizira yolunjika. 2. Vavu yothandiza yoyendetsa ndege.

Zofunikira zazikulu za valve yothandizira ndi: kuwongolera kwakukulu kowongolera, cholakwika chochepa chowongolera, kutsika kwapang'onopang'ono, kuchitapo kanthu movutikira, kutayika kwakukulu kwa gawo, ndi phokoso laling'ono.

Mfundo yogwira ntchito ya valve yothandizira

Valavu yothandizira ndi mtundu wa valavu yowongolera mafuta, yomwe imagwira ntchito ngati kusefukira kosalekeza, kuwongolera kupanikizika, kubwezeretsa dongosolo komanso chitetezo chachitetezo pazida zamagetsi.

Mfundo ya valve yothandizira: Mu ndondomeko yoyendetsera kayendedwe ka pampu, pampu yowonjezera imapereka kuthamanga kosalekeza, ndipo pamene kupanikizika kwa dongosolo kumachepetsedwa, kufunikira kwa kutuluka kudzachepetsedwa. Panthawiyi, valavu yothandizira imatsegula valavu yowongolera ndi kuchepetsa kuti madzi ayambe kusefukira ku thanki ndikuwonetsetsa kuti valavu yolowera imalowa.

Mu dongosolo lokhazikika la kupopera kwapampu, pampu yokhazikika imapereka kuyenda kosalekeza. Pamene kupanikizika kwa dongosolo kumachepetsedwa, kufunikira kothamanga kudzachepetsedwa. Panthawiyi, valve yothandizira imatsegulidwa, kotero kuti kutuluka kwakukulu kumabwereranso ku tank pressure regulator ndi kuchepetsa kupanikizika kwa valve, kuonetsetsa kuti mpweya wotsekemera wa valve, ndiye kuti, kuthamanga kwa mpweya kumakhala kosalekeza. nthawi zambiri amatsegulidwa ndi kusinthasintha kwamphamvu).
