Iyo hydraulic mafuta sefa chinhu chinofanirwawo kusangana nezvinodiwa zvekurasikirwa kwekumanikidza (iyo yakazara yekumanikidza musiyano weyakanyanya kudzvanywa sefa iri pasi pe0.1PMa, uye iyo yakazara yekumanikidza musiyano wemafuta ekudzosa sefa iri pasi pe0.05MPa) kuve nechokwadi chekugadzirisa. kuyerera uye kusefa chinhu hupenyu.Saka isu tinosarudza sei iyo hydraulic oiri sefa nenzira kwayo?Mupepeti anokuudza kuti unofanirwa kufunga nezve zvinotevera 5 zvinhu:
1. Kurongeka kwesefa
Kutanga, sarudza hutsanana hwehuwandu hwematanho zvichienderana nezvinodiwa zve hydraulic system, uye wozosarudza kurongeka kwesefa yemafuta sefa zvichienderana nehutsanana hutsanana maererano netafura yechiratidzo.Iyo inonyanya kushandiswa hydraulic oiri sefa chinhu mumichina yekuvaka ine zita rekusefa degree re10μm.Hutsanana hwemafuta eHydraulic (ISO4406) Kukwenenzverwa kwemazita kwesefa chinhu (μm) Chishandiso renji 13/103 Hydraulic servo valve (ine 3μm sefa element) 16/135 Hydraulic proportional valve (ine 5μm sefa element) 18/1510 General hydraulic components ) (ine 10μm sefa element) 19/1620 general hydraulic components (<10MPa) (ine 20μm sefa chinhu)
Sezvo kurongeka kwezita rekusefa kusingakwanise kunyatso kuratidza kugona kwesefa yechinhu chesefa, iyo dhayamita yeyakaomesesa spherical particle iyo iyo sefa inogona kupfuura pasi peyakatsanangurwa mamiriro ekuyedzwa inowanzo shandiswa seyayo mhedzisiro yekusefa kuratidza zvakananga kusefa kwekutanga kweiyo sefa. ichangobva kuiswa sefa chinhu.Chiyero chakakosha chekuongorora kugona kwe hydraulic oiri sefa chinhu ndeye β kukosha kwakatarwa maererano ne ISO4572-1981E (multi-pass bvunzo), kureva, mafuta akasanganiswa neyakajairwa test powder inotenderedzwa kuburikidza nemafuta sefa kwenguva dzakawanda. , uye chinopinza chemafuta nechinobudisira mafuta zviri pamativi ose esefa yemafuta.chiyero chenhamba yezvimedu.
2. Kuyerera maitiro
Kuyerera uye kudonhedza kudonhedza kwesefa chinhu chinopfuura nepakati pemafuta akakosha maparamita ekuyerera maitiro.Iyo yekuyerera hunhu bvunzo inofanirwa kuitwa zvinoenderana neiyo ISO3968-91 chiyero kudhirowa kuyerera-kudonhedza kudonha hunhu curve.Pasi peiyo yakatemerwa mafuta ekupa kudzvanywa, iyo yakazara dzvinyiriro inodonha (iyo hwerengedzo yekudonhedza kudonhedza kwesefa imba uye kudonhedza kudonha kweiyo sefa element) inofanira kunge iri pazasi 0.2MPa.Kuyerera kwakanyanya: 400lt/min Oil viscosity test: 60to20Cst Minimum flow Turbine: 0℃ 60lt/min Yakanyanya kuyerera Turbine: 0 ℃ 400lt/min
3. Sefa simba
Iyo rupture-impact bvunzo ichaitwa zvinoenderana neISO 2941-83.Musiyano wekumanikidza unodonha zvakanyanya kana iyo sefa element yakuvadzwa inofanira kunge yakakura kupfuura kukosha kwakataurwa.
4. Kuyerera kuneta maitiro
Inofanirwa kuenderana ne ISO3724-90 yakajairwa kuneta bvunzo.Sefa zvinhu zvinofanirwa kuyedzerwa kuneta kwe100,000 cycles.
5. Muedzo wekugadzirisa kwe hydraulic mafuta
Hydraulic mafuta sefa
Iyo yekumanikidza inoyerera inomira bvunzo inofanirwa kuitwa zvinoenderana neiyo ISO2943-83 chiyero kuratidza kuenderana kweiyo sefa zvinhu neiyo hydraulic oiri.
Filtration ratio b ratio inoreva chiyero chenhamba yezvimedu zvakakura pane zvakapihwa saizi mumvura isati yasefa kusvika kunhamba yezvikamu zvakakura pane saizi yakapihwa mumvura mushure mekusefa.Nb=nhamba yezvidimbu zvisati zvasefa Na=nhamba yezvimedu mushure mekusefa X=saizi.
Hydraulic mafuta sefa chinhu inyanzvi izwi muindasitiri yekusefa.Kuti uchenese zviwanikwa zvepakutanga uye kushandiswazve kwezviwanikwa, midziyo yekuchenesa inodiwa.Ikozvino iyo sefa chinhu chinonyanya kushandiswa mukusefa oiri, kusefa kwemhepo, kusefa kwemvura uye mamwe maindasitiri ekusefa.Izvo zvinhu zve hydraulic mafuta sefa chinhu chinonyanya zvinosanganisira bepa sefa chinhu, kemikari fiber sefa element (girazi faibha, simbi fiber sintered inonzwa, polypropylene fiber, polyester fiber) mesh sefa chinhu (stainless simbi mesh) uye mutsara gap sefa chinhu.Iyo hydraulic mafuta sefa chinhu chakakodzera kusefa yakasimba asidhi, yakasimba alkali uye organic solvent.Iyo sefa membrane ndeye yakapetwa yakadzika sefa, iyo ine yakakura sefa nzvimbo, yakaderera pressure musiyano, tsvina yakasimba inobata simba uye hupenyu hurefu hwesevhisi.Kune akasiyana mamodheru uye zvakatemwa zvekusarudza kubva.
