VMGZ decoding - hydraulic mafuta
Zviri mukati
Kazhinji kazhinji, mafuta eVMGZ anoshandiswa semushonga unoshanda mune hydraulic michina. Tsananguro yezita iri: multigrade hydraulic mafuta akasimbiswa.
Kushanda kwemafuta eVGGZ
Mafuta eVMGZ anoshandiswa mu hydraulic control system, pamwe nemadhiraivha emagetsi mune anotevera marudzi emidziyo:
- Mugwagwa unokosha michina
- Kusimudza nekutakura michina
- Muchina wekuvaka
- Zvishandiso zvemasango
- Dzakasiyana mota dzakateedzerwa
Kushandiswa kweVMGZ kunovimbisa kuvimbika kwekushanda kwechigadzirwa, pamwe chete nekutanga kweiyo hydraulic drive pamhepo yakadzika kwazvo tembiricha.
Chinonyanya kukosha pamwe nemafuta aya ndechekuti haidi kuchinjwa kana uchishanda mumwaka wakasiyana. Mafuta akakodzera kushanda patembiricha kubva -35 ° C kusvika + 50 ° C, zvinoenderana nerudzi rwepombi inoshandiswa muchirongwa ichi.
Unyanzvi hunhu hwemafuta VMGZ
Mukugadzirwa kweiri mafuta, yakaderera-viscosity zvicherwa zvinoriumba zvine hushoma simba viscosity inoshandiswa seyakagadzirwa zvinhu. Izvi zvinoriumba zvinotorwa kubva kuzvikamu zve petroleum uchishandisa hydrocracking kana wakisi yakadzika. Uye nerubatsiro rwezvakasiyana zvinowedzerwa uye zvinowedzerwa, mafuta anounzwa kune anodikanwa kuenderana. Mhando dzekuwedzera dzinowedzerwa kumafuta eVMGZ: antifoam, antiwear, antioxidant.
Hydraulic mafuta anoratidza ekushambadza zvakanaka zvivakwa, zvisingaite kupupa furo, ichi chakakosha chivakwa chinobatsira kudzivirira kurasikirwa kwemafuta panguva yekushanda. Uyezve, chigadzirwa ichi chinopesana nekuumbwa kwemvura, iyo inobatsira pane kusimba kwemaitiro. Ichi chigadzirwa chine yakakwirira anti-corrosion zvivakwa uye yakazvisimbisa pachayo sechinhu chakanakisa chishandiso chekudzivirira simbi. Imwe yemipimo yakakosha kugona kugona kugadzira mashandiro pasina kupisa mafuta.
Maitiro ekuita kwemafuta eVGGZ:
- Viscosity isiri pasi pegumi m / s pa10 ° С.
- Viscosity isingasviki 1500 pa40 ° С.
- Viscosity indekisi 160
- Flash pa t isiri pasi pe 135 ° С
- kuomesa t -60 ° С
- Makemikari tsvina haina kubvumidzwa
- Hapana mvura yakabvumidzwa
- Oiri inofanira kunge isingagadziriswe nesimbi
- Kuwedzera kwevanhu kusapfuura 865 kg / m3 pa20 ° C
- Chikamu chevhu hachipfuuri 0,05% yehuwandu hwese
Vagadziri vemafuta VMGZ
Vanotungamira vanogadzira mafuta akadaro ndiwo makambani mana makuru: Lukoil, Gazpromneft, Sintoil, TNK.
Vazhinji vevatengi vemafuta aya vanopa yavo sarudzo vachida makambani Lukoil neGazprom. Pane kufunga kwakasimba pakati pevashandi uye madhiraivha emidziyo yakakosha yekuti ma hydraulic mairi emakambani aya anogadzirwa pamidziyo imwechete kubva kuzvikamu zvakafanana zvemafuta.
Iwe unogona zvakare kazhinji kunzwa mhinduro dzisina kunaka pamusoro pemitengo yemafuta ekunze anounzwa, semuenzaniso, iyo yakapusa mafuta eMobil inodhura zvakapetwa ka2 kana kupfuura VMGZ kubva kune vagadziri vemumba.
Kushivirira chinhu chakakosha mukusarudzwa kwemafuta emagetsi, pamwe nesarudzo yeinjini yemota.
Kana uchisarudza hydraulic mafuta, zvakakosha kusarudza chigadzirwa chemhando yepamusoro, zvikasadaro, pamwe nemafuta epasi-emhando VMGZ, mamwe matambudziko anowanikwa.
- Kuwedzera kusvibiswa kwemagetsi
- Mafirita akavharika
- Kukurumidza kupfeka uye ngura yezvikamu
Nekuda kweizvozvo, nguva yekuzorora inoitika mukugadzirisa kana basa rekugadzira, iro rinobatanidza mutengo wakakwira zvakanyanya kupfuura musiyano wemutengo pakati pemafuta emhando yepamusoro neyekunyepera yakachipa.
Icho chinetso chikuru mukusarudza mugadziri weVMGZ ndiyo ingangoita akafanana maficha emafuta kubva kune akasiyana vagadziri. Izvi zvinokonzeresa padiki diki seti yekuwedzera yezvinoshandiswa nemakambani ese. Panguva imwecheteyo, kuyedza kuhwina mumakwikwi, imwe neimwe yemakambani ekugadzira anozotarisa pane zvimwe zvivakwa zvemafuta, kunyangwe kana zvisina kusiyana nemukwikwidzi.
mhedziso
Mafuta eVMGZ ishamwari isingadzoreke ye hydraulic michina. Nekudaro, iwe unofanirwa kunyatsoswedera kusarudzo yemafuta uye uchifunga zvinotevera zvinhu:
- Kana uchisarudza, zvakakosha kuti unyatsoongorora iwo marongero eiyo hydraulic mashandiro kuti uwane kuti ndeapi mafuta shiviriro anopiwa mune ino mashandiro.
- Izvo zvakakosha kuti utarise oiri kutevedzera ISO uye SAE zviyero
- Paunenge uchisarudza mafuta eVMGZ, mutengo haugone kutariswa seyakanyanya kukosha, izvi zvinogona kuzoita sekusavimbika
Vhidhiyo: VMGZ Lukoil
Mibvunzo nemhinduro:
Mafuta eVmgz anotsanangurwa sei? Iyo yakakora multigrade hydraulic mafuta. Mafuta aya haagadziri sediments, iyo inobvumira kushandiswa kwemaitiro mumhepo yakashama.
Mafuta eVmgz anoshandiswa chii? Iyi multigrade hydraulic oiri inoshandiswa mumidziyo inogara ichishanda mumhepo yakavhurika: kuvaka, kutema matanda, kusimudza uye kutakura, nezvimwe.
Chii chinonzi viscosity yeVmgz? Pakupisa kwe +40 degrees, viscosity yemafuta inobva ku13.5 kusvika ku16.5 sq.mm / s. Nekuda kweizvi, inochengeta zvivakwa zvayo pakumanikidza kusvika ku25 MPa.
