Zosindikiza:Direct Machining a vavu thupi
Malo opanikizika:kupanikizika wamba
Kutentha:imodzi
Zowonjezera zomwe mungasankhe:valavu thupi
Mtundu wa galimoto:zoyendetsedwa ndi mphamvu

Mfundo zofunika kuziganizira
1. Kodi ndodo yosinthira valavu imakulungidwa mpaka osachepera 140bar ndi kuchuluka kwa 350bar?
A: Kuthamanga kwamtundu wa valve balance ndi 140Bar-350bar, zomwe sizikutanthauza kuti kupanikizika kwakukulu kosinthika ndi 350bar ndipo kutsika kochepa kosintha ndi 140bar; 140bar apa ikutanthauza kuti kupanikizika kocheperako kumatha kusinthidwa kukhala 140bar (kupanikizika kwenikweni kumakhala kotsika kuposa 140bar), ndipo 350bar kumatanthauza kuti kukakamiza kowongolera kopitilira muyeso kumatha kusinthidwa kukhala 350bar (kupanikizika kwenikweni kwakukulu ndikwapamwamba kuposa 350bar).
Anthu ena angadabwe kuti, chifukwa chiyani zochulukirapo komanso zocheperako sizingakhazikitsidwe? Monga mankhwala ogulitsa mafakitale, kukula kwa msonkhano wa spool ndi kusiyana kwa kasupe wogwirira ntchito kumatsimikizira kuti ndizovuta kwambiri kukonza malo apamwamba komanso osachepera. Ngati chiwerengero chapamwamba ndi chochepa chiyenera kukhazikitsidwa, mtengo wopangira spool uwu udzakhala wapamwamba kwambiri ndipo wogwiritsa ntchito sangavomereze. Pa nthawi yomweyi, kugwiritsa ntchito kwenikweni kumakhala kopanda tanthauzo.
Mwachidule, zomwe zimatchedwa kusintha kusintha ndi mtengo womwe ungakwaniritse zosowa za chikhalidwe chanu chogwirira ntchito.
2. Kodi valavu yokwanira ingasinthidwe ndi katundu?
A: Ndizosavomerezeka kwambiri kuti musinthe valve yoyezera pansi pa katundu, chifukwa pali chiopsezo chachikulu. Valavu yoyendetsera bwino imathandizira kwambiri kukhazikika kwaulamuliro chifukwa cha mawonekedwe apadera osinthika, koma choyipa cha kapangidwe kameneka ndikuti torque yolekerera malire si yayikulu, makamaka pankhani ya katundu. Pankhani ya katundu wolemetsa, pali mwayi wina woti ndodo yowongolera idzawonongeka
