Zomwe zimayambitsa phokoso ndi kugwedezeka

1 Phokoso lopangidwa ndi mabowo

Mpweya ukalowetsedwa m’mafutawo pazifukwa zosiyanasiyana, kapena mphamvu ya mafuta ikatsika poyerekezera ndi mpweya wa mumlengalenga, mpweya wina wosungunuka m’mafutawo umathamanga kwambiri n’kupanga thovu. Ma thovu amenewa amakhala okulirapo m'dera lotsika kwambiri, ndipo akamayenda ndi mafuta kumalo othamanga kwambiri, amapanikizidwa, ndipo voliyumuyo imakhala yaying'ono kapena ming'oma imatha. M'malo mwake, ngati voliyumuyo ili yaing'ono m'malo othamanga kwambiri, koma imawonjezeka mwadzidzidzi ikapita kumalo otsika kwambiri, kuchuluka kwa thovu mu mafuta kumasintha mofulumira. Kusintha kwadzidzidzi kwa voliyumu kumatulutsa phokoso, ndipo chifukwa njirayi imachitika nthawi yomweyo, imayambitsa kugunda kwa hydraulic ndi kugwedezeka. Kuthamanga ndi kuthamanga kwa doko la valve yoyendetsa ndege ndi doko lalikulu la valve yothandizira oyendetsa ndege zimasiyana kwambiri, ndipo cavitation ndi yosavuta kuchitika, zomwe zimapangitsa phokoso ndi kugwedezeka.

2 Phokoso lopangidwa ndi hydraulic impact

Pamene valavu yothandizira oyendetsa ndege imatsitsidwa, phokoso lamphamvu lidzachitika chifukwa cha kutsika kwadzidzidzi kwa kuthamanga kwa hydraulic circuit. Kuthamanga kwambiri komanso mphamvu zambiri zogwirira ntchito, phokoso lalikulu kwambiri, lomwe limayambitsidwa ndi nthawi yochepa yotsitsa valve yothamanga komanso mphamvu ya hydraulic. Panthawi yotsitsa, kupanikizika kumasintha mwadzidzidzi chifukwa cha kusintha kwachangu kwa mafuta othamanga, zomwe zimapangitsa kuti mafunde amphamvu asokonezeke. Kuthamanga kwamagetsi ndi phokoso laling'ono, lomwe limapanga phokoso laling'ono, koma likaperekedwa ku dongosolo ndi mafuta, ngati limagwirizana ndi gawo lililonse la makina, likhoza kuwonjezera kugwedezeka ndi phokoso. Chifukwa chake, phokoso lamphamvu la hydraulic likachitika, nthawi zambiri limatsagana ndi kugwedezeka kwadongosolo.

Zofunikira zazikulu za valve yothandizira ndi: kupanikizika kwakukulu kowongolera, kusinthasintha kwapang'onopang'ono, kugwedezeka kwapang'onopang'ono, kuchitapo kanthu movutikira, kuchulukitsitsa kwakukulu ndi phokoso lochepa.
