Ntchito zisanu za valve yothandizira

Itha kupangidwa ndi makina atatu owongolera liwiro. Kusefukira kumangoyatsidwa pamene katunduyo adutsa malire omwe adanenedwa (kupanikizika kwadongosolo kumaposa kukakamiza) :1. Kuthamanga kwa dongosolo kumawonjezeka, ndiko kuti, kuthamanga kwa pompu kumakhala kosalekeza (doko la valve nthawi zambiri limatsegula ndi kusinthasintha kwamphamvu). Valve yothandizira nthawi zambiri imakhala ndi zida ziwiri, zomwe zimagwiritsidwa ntchito popanga kukakamiza kumbuyo (chingwe pagawo lamafuta obwerera) kuti atetezeke mochulukira, zomwe zimachepetsa kufunikira koyenda. Valve ya Throttle ilibe ntchito yoyankha molakwika. Valve ya throttle ndi valve yowunikira imatha kuphatikizidwa mu njira imodzi yolumikizira valavu yofananira, yomwe singathe kubweza kusakhazikika kwa liwiro komwe kumachitika chifukwa cha kusintha kwa katundu, pampu yochulukira imapereka kuthamanga kwanthawi zonse, monga chowongolera chakutali, monga valve yotsatizana. Valve yothandizira imagwiritsidwa ntchito ngati valavu yothamanga kwambiri komanso yotsika kwambiri, valavu imatsekedwa, njira yoyendetsera mafuta othamanga komanso njira yoyendetsera liwiro la bypass throttling, nthawi zambiri pokhapokha pomwe katundu amasintha pang'ono kapena zofunikira zokhazikika. osakwera: pakutsitsa mavavu, pamapampu amtundu wa hydraulic system. Pogwiritsa ntchito, valavu ya throttle nthawi zambiri imakhala valavu yomwe imayang'anira kutuluka kwamadzimadzi mwa kusintha gawo la throttling kapena kutalika: mu ndondomeko yoyendetsera kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka chitetezo. throttle speed regulation system. Kotero kuti kupanikizika kwa dongosolo sikulinso kuwonjezeka (kawirikawiri valavu yochepetsera kupanikizika kusiyana ndi kupanikizika kwakukulu kwa dongosolo la 10% mpaka 20%), valve yothandizira.
