Zvinoenderana nekurongeka kwakasiyana kwesefa (saizi yezvimedu zvinosefa kunze kusvibiswa), iyo hydraulic sefa yemafuta sefa ine marudzi mana: coarse sefa, yakajairwa sefa, chaiyo sefa uye yakakosha firita, inogona kusefa kunze kupfuura 100μm, 10～ 100μm zvichiteerana. , 5 ~ 10μm uye 1 ~ 5μm saizi tsvina.
Paunenge uchisarudza Hydraulic sefa element mafuta sefa, funga zvinotevera mapoinzi:
(1) Kurongeka kwesefa kunofanirwa kusangana nezvinodiwa zvakafanotemerwa.
(2) Inogona kuchengetedza kukwana kwakakwana kwekutenderera kwenguva yakareba.
(3) Iyo sefa yepakati ine simba rakakwana uye haizokuvadzwa nekuita kwe hydraulic pressure.
(4) Iyo sefa yepakati ine yakanaka corrosion resistance uye inogona kushanda kwenguva yakareba patembiricha yakatarwa.
(5) Iyo sefa musimboti iri nyore kuchenesa kana kutsiva.
Kune kazhinji anotevera zvinzvimbo zvekuisa hydraulic sefa element oiri sefa mune hydraulic system:
(1) Inofanirwa kuiswa pachiteshi chekukwevera chepombi:
Kazhinji, sefa yemafuta epamusoro inoiswa pamugwagwa wekukweva wepombi kusefa mahombe etsvina kudzivirira iyo hydraulic pombi. Pamusoro pezvo, iyo yekusefa kwesefa yemafuta inofanira kunge yakapetwa kaviri chiyero chekuyerera kwepombi, uye kurasikirwa kwekumanikidza kunofanira kunge kuri pasi pe0.02MPa.
(2) Yakaiswa munzira yekubuda yemafuta yepombi:
Chinangwa chekuisa sefa yemafuta pano ndeyekusefa kunze kwezvinosvibisa zvinogona kupinda muvharuvhu uye zvimwe zvikamu. Kurongeka kwayo kunofanirwa kunge kuri 10 ~ 15μm, uye inokwanisa kumirisana nekumanikidza kwekushanda uye kudzvanywa kwemafuta padunhu reoiri, uye kudonha kunofanirwa kunge kuri pasi pe0.35MPa. Panguva imwecheteyo, chivharo chekuchengetedza chinofanira kuiswa kuti chidzivirire sefa yemafuta kubva pakuvharwa.
(3) Yakamisikidzwa mumugwagwa weoiri wekudzoka weiyo system: Iyi yekumisikidza inoita senge isina kunanga sefa. Kazhinji, chivharo chekumashure chinoiswa kumashure chakafanana nesefa. Kana iyo sefa yakavharwa uye inosvika kune imwe yekumanikidza kukosha, iyo yekumashure yekumanikidza valve inovhura.
(4) Yakaiswa pabazi remafuta redunhu rehurongwa.
(5) Separate filtration system: Pombi ye hydraulic uye sefa yemafuta inogona kugadzirirwa zvakanyanya kune yakakura hydraulic system kuti iite yakazvimirira yekusefa wedunhu.
Mukuwedzera kune sefa yemafuta inodiwa kune iyo yese system mu hydraulic system, iyo yakakosha sefa yemafuta inowanzoiswa zvakasiyana pamberi pezvimwe zvakakosha zvikamu (sevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavha,yakadaro) kuti ave nechokwadi chekushanda kwavo kwakajairika.
