Yogwiritsidwa ntchito ku Mercedes-Benz 722.9 722.8 solenoid valve 0260130035 0260130034 2202271098

1. Chisindikizo chodzilimbitsa chokha chimatengedwa.

◆ Kawirikawiri, pamene ultra-high pressure unloading valve ikugwira ntchito, disc imakankhidwira mmwamba pansi pa mphamvu yapakati. Kukwera kwamphamvu mu dongosolo, kumapangitsanso kukankhira m'mwamba, ndipo kumachepetsa kupanikizika kwapadera kwa malo osindikizira. Komanso, valavu ikatsekedwa, mphamvu yolamulira idzakhudza kwambiri mpando wa valve, womwe ungawononge mosavuta malo osindikizira ndi kuchepetsa moyo wautumiki wa valve. Kudzilimbitsa kopitilira muyeso wothamanga kwambiri wokhala ndi mpando wosinthika, chimbale cha valavu sichimatsukidwa mwachindunji ndi sing'anga, chomwe chimachepetsa kukokoloka kovala. Pamene valavu yatsekedwa, diskiyo imangogwiritsidwa ntchito ndi mphamvu zotanuka za kasupe kakang'ono, zomwe zimapangitsa kuti diski pampando wa valve ikhale yaying'ono kwambiri, ndipo kusindikiza pamwamba sikuli kosavuta kuwonongeka, motero kumapangitsa moyo wautumiki. wa valavu. Chifukwa cha mawonekedwe ake osavuta komanso ntchito yodalirika, imatha kutsimikizira kukhazikika kwa valve pamene ikugwira ntchito pansi pa ultra-high pressure.

2. Wedge disc amatengedwa

Kuchokera pakuwunika kwamakina, chifukwa valavu ya conical ndi mtengo wa cantilever, imakonda kugwedezeka ndi kutopa kwapang'onopang'ono chifukwa cha kuthamanga kwambiri komanso kuthamanga kwamadzi komanso kugwedezeka kwamphamvu. Pakatikati mwa valavu ya valavu ya wedge amapangidwa ndi kudula pakati pa valavu ya silinda pa ndege yolowera, yomwe ili yofanana ndi mtengo wongothandizidwa kuchokera kumakina. Chifukwa chakuti mapeto apansi a diski yake ali pafupi ndi mpando wa valve, kugwedezeka kwa diski kumakhala kochepa kwambiri kapena kovuta, kotero poyerekeza ndi valavu ya cone, valavu ya wedge imakhala yokhazikika bwino pakugwira ntchito.

Kuphatikiza apo, mpando wa valavu ndi kutulutsa valavu zimapangidwa ngati ma nozzles a Venturi, omwe amatha kuchepetsa cavitation ndi kung'anima evaporation. Kuyika dzenje loletsa kuyenda kutsogolo kapena kumbuyo kwa valavu kumatha kuyamwa mbali ya kutsika kwapakati, kuchepetsa kutsika kwapakati musanayambe ndi pambuyo pake, ndikufooketsa cavitation. Ngati pali kung'anima evaporation, si kophweka kutengera pansi-pafupi ndi outflow direction. Kutengera mawonekedwe atsopano ndi njira yabwino yopititsira patsogolo moyo wautumiki wa valavu yamphamvu yamadzi ya valavu yopumira kwambiri. Komabe, kupanikizika kwapang'onopang'ono, kapangidwe kake kayenera kukhala kosavuta.
