Nthawi zambiri otsegula ma hydraulic system otembenuza solenoid valve SV-08

Zida zomwe zimakhala zosavuta kupanga phokoso pazida zama hydraulic nthawi zambiri zimatengedwa ngati mapampu ndi mavavu, ndipo mavavu amakhala makamaka ma valve osefukira ndi ma valve owongolera ma elekitiroma. Pali zinthu zambiri zomwe zimatulutsa phokoso. Pali mitundu iwiri ya phokoso la valve yosefukira: phokoso la liwiro ndi phokoso la makina. Phokoso la phokoso la liwiro limayamba makamaka chifukwa cha kugwedezeka kwamafuta, cavitation ndi hydraulic impact. Phokoso la makina limayamba makamaka chifukwa cha kugunda ndi kugunda kwa magawo mu valavu.

(1) Phokoso lobwera chifukwa cha kukakamiza kosagwirizana

Gawo la valve yoyendetsa ndege ndi gawo losavuta kugwedezeka monga momwe tawonetsera pa Chithunzi 3. Pamene ikusefukira pansi pa kupanikizika kwakukulu, kutsegula kwa axial kwa valve yoyendetsa ndege kumakhala kochepa kwambiri, kokha 0.003 ~ 0.006 cm. Malo otsetsereka ndi ochepa kwambiri, ndipo kuthamanga kwake kumakhala kokwera kwambiri, komwe kumatha kufika 200m / s, zomwe zimayambitsa mosavuta kugawa kwapakati kosagwirizana, mphamvu yamagetsi yamagetsi ya cone valve ndi kugwedezeka. Kuphatikiza apo, elliptical yomwe imayambitsidwa ndi makina a valavu ya cone ndi mpando wa valve ya cone, dothi lomwe limamatira pa doko la valve yoyendetsa komanso kusinthika kwa kasupe woyendetsa kasupe kumayambitsanso kugwedezeka kwa valavu ya cone. Chifukwa chake, nthawi zambiri amaganiziridwa kuti valavu yoyendetsa ndiye gwero la phokoso.

Chifukwa cha kukhalapo kwa zinthu zotanuka (kasupe) ndi misa yosuntha (valavu ya cone), imapanga chikhalidwe cha oscillation, ndipo kutsogolo kwa valve yoyendetsa ndege kumakhala ngati phokoso lamagetsi, kotero kuti kugwedezeka kwa valavu kumakhala kosavuta kuyambitsa. ndi resonance wa valavu lonse ndi kupanga phokoso, amene nthawi zambiri limodzi ndi kuthamanga kwambiri kulumpha.
