1. Izi ezi nzacha
Nke mbụ, chọpụta ọkwa ịdị ọcha nke ntụpọ dị ka mkpa nke sistemu hydraulic si dị, wee họrọ nzacha nzacha nke nzacha mmanụ dịka ọkwa ịdị ọcha dị ka tebụl akara. Ihe nzacha mmanụ hydraulic a na-ejikarị eme ihe n'ime igwe ihe owuwu nwere ogo nzacha aha nke 10μm. Ịdị ọcha nke mmanụ hydraulic (ISO4406) Nzacha aha njirimara nke ihe nzacha (μm) Ngwa ngwa 13/103 hydraulic servo valve (ya na ihe nzacha 3μm) 16/135 valvụ hydraulic proportional valve (ya na 5μm filter element) 18/1510 General hydraulic components (> 10MPa). ) (ya na ihe nzacha 10μm) 19/1620 akụrụngwa hydraulic izugbe (<10MPa) (ya na ihe nzacha 20μm)
Ebe ọ bụ na nzacha nzacha n'ọnụ enweghị ike igosipụta ikike nzacha nke ihe nzacha, dayameta nke ihe nzacha kacha sie ike nke nzacha nwere ike ịgafe n'okpuru ọnọdụ nnwale akọwapụtara ka a na-ejikarị dị ka nzacha ya zuru oke iji gosipụta ozugbo nzacha mbụ nke ihe nzacha arụnyere ọhụrụ. Usoro kachasị mkpa maka ịtụle ikike nke ihe nzacha mmanụ hydraulic bụ uru β kpebisiri ike dabere na ISO4572-1981E (nnwale ọtụtụ ngafe), ya bụ, a na-ekesa mmanụ a gwakọtara na ntụ ntụ ọkọlọtọ ọkọlọtọ site na nzacha mmanụ ọtụtụ oge. , na ntinye mmanụ na mpụta mmanụ dị n'akụkụ abụọ nke nzacha mmanụ. ruru nke ọnụ ọgụgụ nke ahụ.
2. Njiri mara
Ntughari na nrụgide nrụgide nke ihe nzacha na-agafe na mmanụ bụ ihe dị mkpa nke njirimara na-asọpụta. Ekwesịrị ịme ule njirimara erugharị ahụ dị ka ọkọlọtọ ISO3968-91 iji dọpụta njiri mara nrụba-nrụgide. N'okpuru nrụgide ọkọnọ nke mmanụ a na-egosi, ngụkọta nrụgide (nchikota nke mbelata nrụgide nke ụlọ nzacha na nrịba nke ihe nzacha) kwesịrị ịdị n'okpuru 0.2MPa.

3. Ike nyo
A ga-eme nnwale nbibi-mmetụta dị ka ISO 2941-83 si kwuo. Ọdịiche nrụgide nke na-adaba nke ọma mgbe ihe nzacha mebiri emebi kwesịrị ịdị ukwuu karịa uru akọwapụtara.
4. Ebu ike ọgwụgwụ àgwà
Kwesịrị ịdabere na ule ike ọgwụgwụ ISO 3724-90. Ihe nzacha ga-abụrịrị nwale ike ọgwụgwụ maka okirikiri 100,000.
5. Nnwale maka mgbanwe nke mmanụ hydraulic
Ihe nzacha mmanụ hydraulic
Ekwesịrị ime ule nguzogide nrụgide dị ka ọkọlọtọ ISO2943-83 iji nyochaa ndakọrịta nke ihe nzacha na mmanụ hydraulic.

Ihe nzacha mmanụ hydraulic bụ okwu ọkachamara na ụlọ ọrụ nzacha. Iji mee ka ihe ndị mbụ dị na gburugburu ebe obibi dị ọcha na iji ihe onwunwe eme ihe, a chọrọ ngwa nchacha. Ugbu a, ihe nzacha a na-ejikarị eme ihe na nzacha mmanụ, nzacha ikuku, nzacha mmiri na ụlọ ọrụ ndị ọzọ. Ihe nzacha mmanụ hydraulic na-agụnye ihe nzacha akwụkwọ, ihe nzacha kemịkalụ (fiber glass, fiber sintered feel, polypropylene fiber, polyester fiber) mesh filter element (igwe anaghị agba nchara) na ihe nzacha eriri ahịrị. Ihe nzacha mmanụ hydraulic dabara adaba maka nzacha acid siri ike, alkali siri ike na ihe mgbaze organic. Akpụkpọ ahụ nzacha bụ ihe nzacha omimi apịaji, nke nwere nnukwu ebe nzacha, ọdịiche nrụgide dị ala, ikike ijide unyi siri ike yana ogologo ndụ ọrụ. Enwere ụdị dị iche iche na nkọwapụta ịhọrọ.
