I-VMGZ decoding - uwoyela we-hydraulic
Okuqukethwe
Ngokuvamile, uwoyela we-VMGZ usetshenziswa njengoketshezi olusebenzayo kuzinqubo zokubacindezela. Incazelo yaleli gama: uwoyela we-hydraulic multigrade uqinisiwe.
Ukusetshenziswa kukawoyela we-VMGZ
Uwoyela we-VMGZ usetshenziswa ezinhlelweni zokulawula umfutholuketshezi, kanye nasemshinini wokubacindezela kulezi zinhlobo zokusebenza ezilandelayo:
- Imishini ekhethekile yomgwaqo
- Imishini yokuphakamisa nokuthutha
- Imishini yokwakha
- Imishini yamahlathi
- Izimoto ezahlukahlukene ezilandelelwe
Ukusetshenziswa kwe-VMGZ kuqinisekisa ukuthembeka kokusebenza kwedivayisi yezobuchwepheshe, kanye nokuqala kwedrayivu ye-hydraulic emazingeni okushisa omoya aphansi kakhulu.
Okuhlanganiswa okubaluleke kakhulu kwalo kawoyela ukuthi awudingi ukushintshwa lapho usebenza ngezikhathi ezahlukahlukene. Uwoyela ulungele ukusebenza emazingeni okushisa ukusuka ku-35 ° C kuye ku- + 50 ° C, kuya ngohlobo lwepompo elisetshenziswe ohlelweni.
Izici zobuchwepheshe be-VMGZ kawoyela
Ekukhiqizweni kwalo oyili, izinto ezimbiwa phansi ezisetshenziswa nge-viscosity yamaminerali ene-viscosity encane enamandla. Lezi zingxenye zitholakala ezingxenyeni zikaphethiloli usebenzisa i-hydrocracking noma i-waxing ejulile. Futhi ngosizo lwezithasiselo ezahlukahlukene nezengezo, uwoyela ulethwa ekuvumelaneni okufunwayo. Izinhlobo zezithasiselo ezingezwe kumafutha e-VMGZ: i-antifoam, i-antiwear, i-antioxidant.
Uwoyela we-Hydraulic ukhombisa izakhiwo zokuthambisa ezinhle kakhulu, cishe azikho amagwebu, le mpahla ebalulekile isiza ukugwema ukulahleka kukawoyela ngesikhathi sokusebenza. Futhi, lo mkhiqizo uyamelana nokwakheka kwemvula, okunomphumela omuhle ekuqineni kwezinqubo. Le mikhiqizo inezindawo eziphakeme zokulwa nokugqwala futhi izisungule njengezindlela ezinhle kakhulu zokuvikela insimbi. Enye yemingcele ebaluleke kakhulu yikhono lokuqala izindlela ngaphandle kokushisa uwoyela.
Izici zokusebenza kukawoyela we-VMGZ:
- I-viscosity engekho ngaphansi kwe-10 m / s ku-50 ° С.
- I-viscosity engekho ngaphezu kwe-1500 ku-40 ° С.
- Inkomba ye-viscosity 160
- I-Flash at t ingaphansi kuka-135 ° С.
- ukuqina t -60 ° С
- Ukungcola kwemishini akuvunyelwe
- Awekho amanzi avunyelwe
- Amafutha kufanele amelane nokugqwala kwensimbi
- Ubuningi abukho ngaphezu kuka-865 kg / m3 ngo-20 ° C
- Inani lesidumbu alikho ngaphezu kuka-0,05% wesisindo esiphelele
Abakhiqizi bakawoyela i-VMGZ
Abakhiqizi abahamba phambili bamafutha anjalo yizinkampani ezinkulu ezine: iLukoil, iGazpromneft, iSintoil, i-TNK.
Iningi labathengi balo mafutha banikeza ukukhetha kwabo bavuna izinkampani iLukoil neGazprom. Kunombono oqinile phakathi kwabasebenzi nabashayeli bemishini ekhethekile yokuthi uwoyela wokubacindezela walezi zinkampani ukhiqizwa kwimishini efanayo kusuka ezingxenyeni ezifanayo zikawoyela.
Ungase futhi uzwe izimpendulo ezingezinhle mayelana namanani kawoyela we-hydraulic angenisiwe, ngokwesibonelo, uwoyela weMobil olula kakhulu uzobiza ama-2-3 ngaphezulu kwe-VMGZ kusuka kubakhiqizi basekhaya.
Ukubekezelelana kuyisici esibalulekile ekukhetheni uwoyela wokubacindezela, kanye nasekukhetheni uwoyela wenjini yemoto.
Lapho ukhetha uwoyela wokubacindezela, kubalulekile ukukhetha umkhiqizo wekhwalithi, ngaphandle kwalokho, kanye namafutha we-VMGZ asezingeni eliphansi, kunezinkinga eziningi ezitholakalayo:
- Ukwanda kokungcola kwama-hydraulic
- Izihlungi ezivalekile
- Ukugqoka okusheshayo nokugqwala kwezingxenye
Ngenxa yalokho, isikhathi sokuphumula senzeka emsebenzini wokulungisa noma wokukhiqiza, okubandakanya izindleko eziphakeme kakhulu kunokwehluka kwentengo phakathi kukawoyela osezingeni eliphakeme nenkohliso eshibhile.
Ubunzima obukhulu bokukhetha umenzi we-VMGZ ukwakheka okucishe kufane kwamafutha kusuka kubakhiqizi abahlukahlukene. Lokhu kungenxa yesisekelo esincane sezithasiselo ezisetshenziswa yizo zonke izinkampani. Ngasikhathi sinye, sizama ukuwina emncintiswaneni, ngayinye yezinkampani ezikhiqizayo izogxila ezintweni ezithile zikawoyela, noma ngabe yehlukile kumbangi.
isiphetho
Uwoyela we-VMGZ ungumlingani ongenakubuyiselwa endaweni yezindlela zokubacindezela. Kodwa-ke, udinga ukusondela ngokucophelela ekukhetheni kukawoyela futhi ucabangele lezi zinto ezilandelayo:
- Lapho ukhetha, kubalulekile ukutadisha ngokucophelela ukucaciswa kwemishini ye-hydraulic ukuze uthole ukuthi yikuphi ukuhlinzekwa kwamafutha okunikezwa kule ndlela.
- Kubalulekile ukuhlola uwoyela ngokuqhathaniswa namazinga we-ISO ne-SAE
- Lapho ukhetha uwoyela we-VMGZ, intengo ayikwazi ukubhekwa njengombandela oyinhloko, lokhu kungahle kube ukonga okungabazekayo

Imibuzo nezimpendulo:
Ngabe uwoyela we-Vmgz uchazwa kanjani? Kuwuwoyela owugqinsi we-hydraulic multigrade. Lawa mafutha awakhi ama-sediments, okuvumela ukusetshenziswa kwezindlela emoyeni ovulekile.
Amafutha e-Vmgz asetshenziselwa ini? Lawa mafutha e-hydraulic amaningi asetshenziswa kumishini esebenza njalo emoyeni ovulekile: ukwakhiwa, ukugawulwa kwemithi, ukuphakamisa nokuthutha, njll.
Iyini i-viscosity ye-Vmgz? Ekushiseni kwama-+40 degrees, i-viscosity yamafutha isuka ku-13.5 kuya ku-16.5 sq.mm / s. Ngenxa yalokhu, igcina izakhiwo zayo ezingcindezini ezifika ku-25 MPa.
