Chosefera chamafuta amtundu wa hydraulic chiyeneranso kukwaniritsa zofunikira za kutsika kwamphamvu (kusiyana kwathunthu kwa fyuluta yothamanga kwambiri ndi yochepera 0.1PMa, ndipo kusiyana kwathunthu kwa fyuluta yobwerera mafuta ndi yochepera 0.05MPa) kuonetsetsa kukhathamiritsa kwa moyo wa flow and sefa element.Ndiye timasankha bwanji fyuluta yamafuta a hydraulic molondola?Mkonzi akukuuzani kuti muyenera kuganizira mbali 5 zotsatirazi:

1. Kusefedwa kolondola

Choyamba, dziwani ukhondo wa madontho molingana ndi zosowa za hydraulic system, kenako sankhani kulondola kwa fyuluta yamafuta molingana ndi mulingo waukhondo malinga ndi tebulo lachizindikiro.Chosefera chamafuta a hydraulic chomwe chimagwiritsidwa ntchito kwambiri pamakina omanga chimakhala ndi digiri ya kusefera ya 10μm.Ukhondo wamafuta a Hydraulic (ISO4406) Kulondola mwadzina kusefera kwa zinthu zosefera (μm) Mtundu wa ntchito 13/103 valavu ya Hydraulic servo (yokhala ndi 3μm sefa element) 16/135 Vavu yofananira ya Hydraulic (yokhala ndi 5μm sefa) 18/1510 General hydraulic components ) (ndi 10μm fyuluta chinthu) 19/1620 general hydraulic zigawo zikuluzikulu (<10MPa) (ndi 20μm fyuluta chinthu)

Popeza kuti kusefera kwadzidzidzi sikungathe kuwonetsa mphamvu ya kusefera kwa zinthu zosefera, kukula kwa tinthu tating'onoting'ono tating'onoting'ono tomwe fyulutayo imatha kudutsa pamayesero omwe atchulidwa nthawi zambiri amagwiritsidwa ntchito ngati kusefera kwake kokwanira kuti awonetsere kusefera koyambirira. chinthu chosefera chatsopano.Mulingo wofunikira kwambiri pakuwunika kuthekera kwa sefa yamafuta a hydraulic ndi mtengo wa β womwe umatsimikiziridwa molingana ndi ISO4572-1981E (mayeso ophatikizika ambiri), ndiye kuti, mafuta osakanikirana ndi ufa woyeserera amafalitsidwa kudzera musefa yamafuta nthawi zambiri. , ndi polowera mafuta ndi potulukira mafuta zili mbali zonse za fyuluta yamafuta.chiŵerengero cha chiwerengero cha particles.

2. Makhalidwe oyenda

Kuthamanga ndi kutsika kwamphamvu kwa fyuluta yomwe imadutsa mumafuta ndi magawo ofunikira amayendedwe oyenda.Mayeso amayendedwe amayenera kuchitidwa molingana ndi muyezo wa ISO3968-91 kuti ajambule mayendedwe otsika.Pansi pa mphamvu yoperekera mafuta, kutsika kwathunthu (kuchuluka kwa kutsika kwapanyumba kwa fyuluta ndi kutsika kwamphamvu kwa chinthu chosefera) nthawi zambiri kuyenera kukhala pansi pa 0.2MPa.Kuthamanga kwakukulu: 400lt / min Mayeso a viscosity yamafuta: 60to20Cst Kuthamanga kochepa kwambiri kwa Turbine: 0 ℃ 60lt / mphindi Kuthamanga kwakukulu kwa Turbine: 0 ℃ 400lt / min

3. Sefa mphamvu

Kuyesa kwa rupture-impact kudzachitika molingana ndi ISO 2941-83.Kusiyana kwamphamvu komwe kumatsika kwambiri pamene fyuluta yawonongeka iyenera kukhala yaikulu kuposa mtengo wotchulidwa.

4. Makhalidwe a kutopa akuyenda

Ayenera kukhala molingana ndi muyezo wa kutopa wa ISO3724-90.Zosefera ziyenera kuyesedwa kutopa kwa mizunguliro 100,000.

5. Kuyesa kusinthika kwamafuta a hydraulic

Zosefera zamafuta a Hydraulic

Kuyesedwa kwa kuthamanga kwa kuthamanga kuyenera kuchitidwa molingana ndi ISO2943-83 kuti zitsimikizire kugwirizana kwa zinthu zosefera ndi mafuta a hydraulic.

Sefera chiŵerengero cha b chiŵerengero amatanthauza chiŵerengero cha chiwerengero cha particles zazikulu kuposa kukula anapatsidwa mu madzimadzi pamaso kusefera kwa chiwerengero cha particles zazikulu kuposa kupatsidwa kukula mu madzimadzi pambuyo kusefera.Nb=chiwerengero cha tinthu tisanasefe Na=chiwerengero cha tinthu tating'onoting'ono titatha kusefera X=kukula kwa tinthu.

Chosefera mafuta a Hydraulic ndi nthawi yaukadaulo pantchito yosefera.Pofuna kuyeretsa zoyambira zachilengedwe ndikugwiritsanso ntchito zinthu, zida zoyeretsera zimafunikira.Tsopano chinthu chosefera chimagwiritsidwa ntchito kwambiri pakusefera kwamafuta, kusefera kwa mpweya, kusefera kwamadzi ndi mafakitale ena osefera.Zinthu zosefera zamafuta a hydraulic zimaphatikizanso zinthu zosefera pamapepala, zinthu zosefera zamafuta (zosefera zamagalasi, zitsulo zachitsulo zomverera, ulusi wa polypropylene, ulusi wa polyester) ma mesh sefa (ma mesh osapanga dzimbiri) ndi chinthu chosefera mzere.Chosefera chamafuta a hydraulic ndichoyenera kusefa asidi amphamvu, alkali wamphamvu komanso zosungunulira za organic.Sefa nembanemba ndi fyuluta yakuya yopindika, yomwe ili ndi malo osefera akulu, kusiyana kocheperako, mphamvu yogwira dothi komanso moyo wautali wautumiki.Pali mitundu yosiyanasiyana ndi mafotokozedwe omwe mungasankhe.
