Malo ena okonzera amayang'ana ndikusintha gulu la jekeseni wamafuta kwambiri.Ena amangoyang'ana ndi kusintha mphamvu ya jekeseni wa mafuta pachiyambi, ndipo zinthu zina zomwe siziyenera kuphweka zachepetsedwa.Izi ndi zolakwika.Timakhulupirira kuti kusinthaku kuyenera kuchitika motsatira ndondomekoyi.Sikuti mphamvu ya jakisoni wamafuta ikuyenera kuyang'aniridwa ndikusinthidwa, komanso ngodya ya jekeseni wamafuta, mtundu wa jakisoni wamafuta, ndi zina zotere ziyenera kuyang'aniridwa molingana ndi momwe zilili, makamaka pakulimba kwa jekeseni wamafuta.kudzutsa chidwi chonse.
Yang'anani kulimba kwa jekeseni wamafuta: Yambitsirani choyezera jekeseni wamafuta, tengani jekeseni wamafuta ambiri okhala ndi mabowo ambiri monga chitsanzo, kwezani mphamvu yodziwikiratu ya choyezera jekeseni yamafuta mpaka 2324 MPa, ndikuwonjezera mphamvu ya jekeseni wamafuta. jekeseni mpaka 24 ~ 25 MPa, pamene kukakamiza kwa jekeseni woyesa kutsika kuchokera ku 20 MPa kufika ku 18 MPa, nthawi ya jekeseni iyenera kukhala 9 ~ 20 s, ndipo kugwiritsa ntchito kovomerezeka sikuyenera kuchepera 9 s.
Ndikofunikira kudziwa kuti: choyamba, choyezera jekeseni chiyenera kukwaniritsa zofunikira zaumisiri, dera la mafuta othamanga kwambiri liyenera kukhala lolimba, ndipo ntchito yosindikiza ya msonkhano wa valve yotulutsa mafuta pa tester iyenera kukhala yabwino.Onjezani mpweya wozungulira mafuta, lepheretsani cholumikizira chamafuta othamanga kwambiri, pitilizani kupereka mafuta ndikuwonjezera kukakamiza, kuti kukakamiza kodziwikiratu kukwera mpaka 23 ~ 24 MPa.Pamene kukakamiza kwa tester kutsika kuchokera ku 20 MPa kufika ku 18 MPa, nthawiyo siyenera kukhala yocheperapo mphindi zitatu.Kachiwiri, jekeseni yamafuta iyenera kuyang'aniridwa osachepera kawiri, ndipo mtengo wapakati uyenera kutengedwa.Ndipo kusiyana kwa nthawi pakati pa nthawi ziwiri zoyandikana sikudzakhala kwakukulu kuposa 2 s pamtundu wa pintle ndi mbale, ndipo sikudzakhala kwakukulu kuposa 3 s pamtundu wautali wa porous.
