Ma hydraulic proportional rotary security solenoid valve 23871482

Monga valavu yotetezera kuteteza kuchulukitsitsa kwa hydraulic system valve yothandizira imagwiritsidwa ntchito pofuna kupewa kuchulukitsitsa kwa dongosolo, valve nthawi zambiri imatsekedwa. Pamene kupanikizika kutsogolo kwa valve sikudutsa malire okonzedweratu, valavu imatsekedwa popanda kusefukira kwa mafuta. Pamene kupsyinjika pamaso pa valavu kupitirira malire a malire awa, valavu imatsegula mwamsanga, ndipo mafuta amabwereranso ku thanki kapena dera lochepetsetsa, motero amalepheretsa kudzaza kwa hydraulic system. Kawirikawiri valavu yotetezera imagwiritsidwa ntchito mu dongosolo lokhala ndi pampu yosinthika, ndipo kupanikizika kwakukulu komwe kumayendetsedwa ndi nthawi zambiri kumakhala 8% mpaka 10% kuposa kupanikizika kwa dongosolo.

Monga valavu yowonongeka, kupanikizika kwa hydraulic system kumasungidwa kosalekeza mu dongosolo la mpope wochulukira, ndipo chinthu cha throttle ndi katundu zimagwirizana. Panthawiyi, valve nthawi zambiri imakhala yotseguka, nthawi zambiri mafuta ochulukirapo, ndi mafuta osiyanasiyana omwe amafunidwa ndi njira yogwirira ntchito, kuchuluka kwa mafuta otayika kuchokera ku valve ndi kwakukulu komanso kochepa, kuti asinthe ndi kulinganiza kuchuluka kwa mafuta omwe amalowa. hydraulic system, kotero kuti kuthamanga kwa hydraulic system kumakhalabe kosasintha. Komabe, chifukwa cha kutayika kwa mphamvu mu gawo lakusefukira, nthawi zambiri amagwiritsidwa ntchito m'dongosolo ndi pampu yochepetsera mphamvu yochepa. Kuthamanga kosinthidwa kwa valve yothandizira kuyenera kukhala kofanana ndi kupanikizika kwa dongosolo.

Kuwongolera kupanikizika kwakutali: Lumikizani cholowera chamafuta cha chowongolera chakutali ku doko loyang'anira kutali (kutsitsa doko) la valavu yothandizira kuti mukwaniritse kuwongolera kwakutali mkati mwa valavu yayikulu yothandizira.

Monga valavu yotsitsa, doko loyendetsa kutali (kutsitsa) la valve yothandizira limagwirizanitsidwa ndi thanki yamafuta ndi valve yobwerera, kuti mzere wa mafuta utsitsidwe.

Kwa masitepe ambiri othamanga kwambiri komanso otsika kwambiri, pamene valavu yobwerera imagwirizanitsa doko loyendetsa kutali (kutsitsa doko) la valve yothandizira ndi ma valve angapo oyendetsa kuthamanga kwakutali, kulamulira kwapang'onopang'ono kwapamwamba ndi kutsika kumatha kuchitika.

Kuti agwiritsidwe ntchito ngati valavu yotsatizana, chivundikiro chapamwamba cha valavu chothandizira chimasinthidwa kukhala doko la kukhetsa mafuta, ndipo dzenje la axial lomwe limagwirizanitsidwa ndi valavu yaikulu ndi chivundikiro chapamwamba chatsekedwa, monga momwe tawonetsera mu Chithunzi e, ndi doko lotayira mafuta. valavu yayikulu imagwiritsidwa ntchito ngati chotengera chachiwiri chamafuta kuti chigwiritsidwe ntchito ngati valavu yotsatizana.

Ma valve otsitsa otsitsa amagwiritsidwa ntchito pamapampu ndi ma accumulator, monga momwe tawonetsera pa Chithunzi f. Pamene mpope ikugwira ntchito bwino, imapereka mafuta ku accumulator. Pamene mphamvu ya mafuta mu accumulator ifika kukakamiza kofunikira, valavu yothandizira imayendetsedwa kupyolera mu mphamvu ya dongosolo kuti pampu itulutse, ndipo dongosolo lidzapereka mafuta ndi accumulator ndikugwira ntchito mwachizolowezi; Pamene mphamvu ya mafuta ya accumulator imatsika, valve yothandizira imatsekedwa, ndipo pampu yamafuta ikupitiriza kupereka mafuta ku accumulator, motero kuonetsetsa kuti dongosololi likugwira ntchito bwino.
