Indlela ye-servo ohlelweni lwe-hydraulic inembile kakhulu (imvume evamile i-3μm), evinjelwa kalula yizinhlayiya emafutheni, okuholela ekuhlulekeni kokulawula.Izinhlayiya zamafutha okugcoba zizosheshisa ukugqokwa kwezimpawu ohlelweni, ngaleyo ndlela kunciphise ukuthembeka nempilo yesevisi yemishini.Ngakho-ke, kuyadingeka ukukala ukuhlanzeka kwemikhiqizo yamafutha ngendlela enembile, ebizwa ngokuthi "ukuhlanzeka".
Njengamanje, i-ISO 4406 ne-NAS 1638 zisetshenziswa kabanzi ukuveza ukuhlanzeka kukawoyela.Kukhona ukuxhumana okuthile phakathi kwamazinga amabili.I-China okulingana ne-ISO 4406-1999 standard yamukelwe, kwakhiwa "ikhodi yezinga lokungcoliswa kwamafutha ezinhlayiyana ze-hydraulic" GB/T 14039-2002 kazwelonke.
Izinga le-ISO 4406-1999 ukunquma inani lezinhlayiya > 4μm, > 6μm, > 14μm ku-100ml kawoyela, Izinga le-ISO 4406 lokuhlanzeka labekwa etafuleni yi-International Organization for Standardization ngo-1991 ukuze kubhekiselwe kumakhodi ebanga lokungcoliswa (ukuhlanzeka) .
I-ISO 4406 ikhethelwa u-5μm, 15μm lawa osayizi ababili, ngoba ucwaningo luye lwabonisa ukuthi izinhlayiya ze-5μm zizodala ukuguga okukhulu, futhi izinhlayiya ze->15μm zizobangela ukunamathela kwezingxenye ze-hydraulic, ngakho-ke laba osayizi ababili bangabonisa ngokuyisisekelo ukuguga kwamafutha, izimo zokunamathela.
Indlela yokuguqula ukuhlanzeka kwamafutha we-hydraulic ngaphansi kwamazinga ahlukene?Ithebula elilandelayo libonisa indlela yokuguqula phakathi kwetafula lenhlanzeko le-ISO4406 namazinga ahlukene:
Amathebula akulo mhlahlandlela avumela abasebenzisi ukuthi basebenzise izinto zokubala zezinhlayiyana ezizenzakalelayo ukuze baboneubudlelwano phakathi kwezibalo zezinhlayiyana ezingavuthiwe ezinosayizi abahlukahlukene kanye nezinombolo zekhodi yokubika zeizindinganiso ezihlukahlukene zokungcola.
Qaphela ukuthi okunye okufakiwe kwethebula kuchazwa njengezibalo eziqoqiwe (isb. > 6µm”) kanyeezinye zichazwa njengezibalo ezihlukanisayo (isb. 6–14µm”).
Izimo zosayizi bezinhlayiyana ezinikezwe njengokuthi “µm” zibhekisela ku-ACFTD (okungukuthi, Uthuli Lokuhlola Lokuhlanza I-Air Cleaner)ukusatshalaliswa.Izimo zosayizi bezinhlayiyana ezinikezwe njengokuthi “µm(c)” zibhekise ku-MTD (okungukuthi ISO Medium TestUthuli) ukusatshalaliswa.
Wonke amazinga ayizibalo ngevolumu ngayinye, futhi ahlinzeka ngezindlela ezilula zokuguqula izinhlayiyanaibala emikhawulweni okulula ukuyihumusha.Ngokuqaphela izidingo zezinga,
izibalo zezinhlayiya zingaguqulwa ngokunembile zibe amazinga okungcola.
Idatha ye-NAS1638
Izinga lokuhlanzeka le-NAS 1638 lasungulelwa izingxenye ze-aerospace e-US kanyeisasetshenziswa kabanzi ekusetshenzisweni kwamandla oketshezi lwezimboni kanye ne-aerospace.
Izibalo ziyizibalo ezihlukene, futhi isigaba se-NAS sivame ukubikwa njengesibalo esisodwaemele isibalo esiphezulu sezinhlayiyana ezivunyelwe (okungukuthi isimo esibi kakhulu) sezinhlayiyana ezimisiweububanzi besayizi.
