Inkqubo ye-servo kwinkqubo ye-hydraulic ichaneke kakhulu (i-clean clearance yi-3μm), evalwe ngokulula ngamaqhekeza kwioli, ekhokelela ekungaphumeleli kolawulo.Amacandelo e-oyile yokuthambisa aya kukhawuleza ukunxiba kwezitywina kwinkqubo, ngaloo ndlela ukunciphisa ukuthembeka kunye nobomi benkonzo yezixhobo.Ngoko ke, kuyimfuneko ukulinganisa ukucoceka kweemveliso zeoli ngendlela echanekileyo, ebizwa ngokuthi "ukucoceka".
Okwangoku, i-ISO 4406 kunye ne-NAS 1638 zisetyenziswa ngokubanzi ukubonisa ukucoceka kwe-oyile.Kukho imbalelwano ethile phakathi kwale migangatho mibini.I-China elinganayo yamkelwa umgangatho we-ISO 4406-1999, yakha "ikhowudi yenqanaba longcoliseko lwe-oyile ye-hydraulic eqinileyo" GB/T 14039-2002 umgangatho wesizwe.
Umgangatho we-ISO 4406-1999 kukumisela inani lamasuntswana> 4μm,>6μm,>14μm kwi-100ml yeoli, Umgangatho wococeko we-ISO 4406 wabekwa yi-International Organisation for Standardization ngo-1991 ngokubhekisele kwiikhowudi zebakala longcoliseko (ucoceko) .
I-ISO 4406 ikhethelwe i-5μm, i-15μm ezi sayizi zimbini, kuba uphononongo lubonise ukuba amasuntswana angama-5μm aya kubangela ukuguga okunzulu, kwaye> amasuntswana angama-15μm aya kubangela ukuba axinge amacandelo oxinzelelo, ngoko ke ezi sayizi zimbini zinokubonisa ngokusisiseko ukunxitywa kweoyile, iimeko zokuxinga.
Indlela yokuguqula ukucoceka kweoli ye-hydraulic phantsi kwemigangatho eyahlukeneyo?Le theyibhile ilandelayo ibonisa indlela yokuguqula phakathi kwetafile yococeko ye-ISO4406 kunye nemigangatho eyahlukeneyo:
Iitafile kwesi sikhokelo zivumela abasebenzisi ukuba basebenzise izixhobo zokubala ezizenzekelayo eziphathwayo ukuze baboneubudlelwane phakathi kwamanani amasuntswana ekrwada ngokobukhulu obahlukeneyo kunye namanani ekhowudi yokunika ingxeloimigangatho eyahlukeneyo yongcoliseko.
Qaphela ukuba amanye amangeniso etheyibhile achazwa njengamanani olongezelekayo (umz. "> 6µm”) kunyeezinye zichazwa ngokubala ngokwahlukileyo (umz. 6–14µm”).
Izehlo zobungakanani bamasuntswana anikiweyo njenge “µm” zibhekisa kwi-ACFTD (oko kukuthi isicoci soMoya esiLuva uthuli)unikezelo.Amathuba obungakanani bamasuntswana anikwe njenge “µm(c)” abhekisa kwiMTD (okt ISO Medium TestUthuli) unikezelo.
Yonke imigangatho ikwizibalo ngokomthamo ngamnye, kwaye ibonelela ngeendlela ezilula zokuguqula amasuntswanaibala kwimida ekulula ukuyitolika.Ngokuqaphela iimfuno zomgangatho,
amanani amasuntswana anokuguqulwa ngokuchanekileyo kumanqanaba ongcoliseko.
NAS1638
Umgangatho wococeko we-NAS 1638 waphuhliswa kumacandelo e-aerospace e-US kunyeisasetyenziswa ngokubanzi kwimizi-mveliso kunye nosetyenziso lwamandla olwelo lwe-aerospace.
Amanani ngamanani ahlukeneyo, kwaye iklasi ye-NAS idla ngokuchazwa njengenani elinyeemele amanani aphezulu amasuntswana avumelekileyo (okt imeko embi kakhulu) kwisuntswana elichongiweyouluhlu lobungakanani.
