Gịnị bụ ụkpụrụ nke hydraulic?

Ụkpụrụ nke hydraulic Jack:
Ihe mejupụtara: Nnukwu cylinder mmanụ 9 na nnukwu piston 8 mejupụtara hydraucic cydraucic. Onye ahụ lere aka 1, obere cylinder mmanụ 2, obere piston 3, na valves chekwaa 4 na 7 mejupụtara ntuziaka hydraulic mgbapụta.
1.Ọ bụ aka weliri obere piston elu, olu nke ụlọ mmanụ na ala njedebe nke obere piston ga-abawanye iji mepụta oghere mpaghara. N'oge a, otu a na-emeghe valvel 4 na mmanụ na mmanụ mmanụ 12 site na mmanụ Saịpụ 5; Mgbe a na-agbanye aka, obere piston na-akpali, nrụgide dị na obere ụlọ piston na-awa, nke a na-emechi valve 4, na otu valve 7 emepere. Mmanụ a na-etinye n'ime obere ụlọ nke na-ebugharị cylinder 9 site na pipe 6 iji mee ka nnukwu ọkpụkpụ mee ka ọ dị elu.
2.Mgbe aka ahụ welie ọzọ na-amachi mmanụ, otu ndepụta valve 7 na-emechi emechi, nke mere na mmanụ ahụ enweghị ike ịbanye na ya, yabụ na-ejide onwe ya na-agaghị adakwasị onwe ya. Site n'ịdọghachi aka na-azụ ya mgbe niile, mmanụ nwere ike na-aga n'ihu hydraulically ntụ ọka nke na-ebuli cylinder iji ji nwayọọ nwayọọ bulie ihe dị arọ.
3.Ọ na-emeghe valve Valve 11, mmanụ dị ala nke na-ebugharị cylinder nke na-ebugharị mmanụ mmanụ site na pọvve 10, na ibu agha kwụsịrị. Nke a bụ ụkpụrụ nke hydraulic Jack.
