Malinga ndi kulondola kwa kusefera kosiyanasiyana (kukula kwa tinthu ting'onoting'ono tosefera zonyansa), fyuluta yamafuta a hydraulic ili ndi mitundu inayi: fyuluta yowoneka bwino, fyuluta wamba, fyuluta yolondola komanso fyuluta yabwino kwambiri, yomwe imatha kusefa kuposa 100μm, 10～ 100μm motero., 5 ~ 10μm ndi 1 ~ 5μm kukula zonyansa.
Posankha zosefera zamafuta a Hydraulic, lingalirani mfundo izi:
(1) Kulondola kwa kusefa kuyenera kukwaniritsa zofunikira zomwe zidakonzedweratu.
(2) Ikhoza kusunga mphamvu yokwanira yozungulira kwa nthawi yaitali.
(3) Chigawo cha fyuluta chimakhala ndi mphamvu zokwanira ndipo sichidzawonongeka ndi mphamvu ya hydraulic.
(4) Chosefera pachimake chimakhala ndi kukana bwino kwa dzimbiri ndipo chimatha kugwira ntchito kwa nthawi yayitali pakutentha komwe kwanenedwa.
(5) Chosefera pachimake ndichosavuta kuyeretsa kapena kusintha.
Nthawi zambiri pamakhala malo otsatirawa pakuyika hydraulic filter element oil filter mu hydraulic system:
(1) Iyenera kukhazikitsidwa pa doko loyamwa la mpope:
Nthawi zambiri, fyuluta yamafuta pamtunda imayikidwa mumsewu woyamwa wa mpope kuti usefe tinthu tambiri toyipa kuti titeteze pampu ya hydraulic.Kuphatikiza apo, kusefa kwamafuta amafuta kuyenera kukhala kuwirikiza kawiri kuchuluka kwa mpope, ndipo kutaya kwamphamvu kuyenera kukhala kosakwana 0.02MPa.
(2) Anayika pa potuluka mafuta msewu wa mpope:
Cholinga choyika fyuluta yamafuta apa ndikusefa zonyansa zomwe zingalowe mu valve ndi zigawo zina.Kusefedwa kwake kuyenera kukhala 10 ~ 15μm, ndipo kumatha kupirira kupanikizika kogwira ntchito komanso kukhudzidwa kwamafuta ozungulira, ndipo kutsika kwake kuyenera kukhala kosakwana 0.35MPa.Pa nthawi yomweyi, valavu yotetezera iyenera kuikidwa kuti iteteze fyuluta yamafuta kuti isatsekedwe.
(3) Kuyika pa msewu wobwerera mafuta wa dongosolo: Kukhazikitsa uku kumakhala ngati fyuluta yosalunjika.Kawirikawiri, valavu yakumbuyo yam'mbuyo imayikidwa mofanana ndi fyuluta.Fyuluta ikatsekedwa ndikufikira pamtengo wina wokakamiza, valavu yakumbuyo yakumbuyo imatsegulidwa.
(4) Adayikidwa pagawo lamafuta anthambi a dongosolo.
(5) Makina osefera osiyana: Pampu ya hydraulic ndi fyuluta yamafuta imatha kukhazikitsidwa mwapadera kuti pakhale makina akuluakulu a hydraulic kuti apange gawo lodziyimira pawokha.
Kuphatikiza pa fyuluta yamafuta yofunikira pa dongosolo lonse la hydraulic system, fyuluta yapadera yamafuta nthawi zambiri imayikidwa padera kutsogolo kwa zigawo zina zofunika (monga ma servo valves, ma valve olondola, ndi zina zotero) kuti atsimikizire ntchito yawo yachibadwa.
