Uwoyela weHydraulic VMGZ
Okuqukethwe
Ezweni lethu, ingxenye yamafutha we-hydraulic ithuthukisiwe. Futhi omunye wemikhiqizo yalesi sigaba uwoyela VMGZ. Lesi sifinyezo simele ukuthi: "Amafutha ashubile we-hydraulic azo zonke izinkathi zonyaka." Lolu hlobo lusabalele ezweni lakithi. Uwoyela weHydraulic walolu hlobo usebenza kumayunithi amaningi. Eyaziwa ezimweni eziningi njenge-VMG three.
Qamba ngokweGOST
Ngokusho kwe-GOST 17479.3, lolu hlobo lwaqanjwa ngokuthi MG-15-V:
- "MG" - amaminerali hydraulic uwoyela;
- "15" - isigaba se-viscosity. Lokhu kusho ukuthi ku-40°C i-kinematic viscosity ingu-13,50 - 16,50 mm2/s (cSt)
- "B" - iqembu lokusebenza. Lokhu kusho ukuthi uwoyela wamaminerali akhiwe nge-antioxidant, anti-corrosion kanye nezithasiselo zokulwa nokugqoka. Indawo enconyiwe yohlelo lokusebenza amasistimu we-hydraulic anamaphampu azo zonke izinhlobo ngengcindezi engaphezu kuka-25 MPa kanye nezinga lokushisa likawoyela elingu-90 ° C.
Izimpawu, ububanzi
I-VMGZ isetshenziswa njengoketshezi olunamanzi amaningi emikhakheni ehlukene yokukhiqiza, yokwakha, emahlathini, nakuzo zonke izindawo lapho kungenzeka khona ubuchwepheshe bama-hydraulic. Lokhu kungenxa yokuthi uwoyela we-VMGZ uguquguquka kakhulu, ugcinwa ngaphansi kwezimo zokusebenza kusuka -35 ° С kuya +50 ° С, okuvumela imishini ukuthi isebenze ezindaweni eziningi zezwe lethu ebusika nasehlobo ngaphandle kwesidingo. ukufaka esikhundleni uketshezi olunamanzi. Ezimweni zaseRussia emaphakathi, kunconywa ukuthi uyisebenzise njengesitshalo sasebusika. Futhi inzuzo enkulu yalolu hlobo ukuthi ingasetshenziswa ukuqala ama-hydraulic motors emazingeni okushisa aphansi.
I-VMGZ itholakala ngezinhlobonhlobo ezintathu ezihlukile endaweni yokuthulula kanye ne-viscosity (iphoyinti eliphansi lokuthela, i-viscosity ephansi):
- I-VMGZ-45°N
- I-VMGZ-55°N
- I-VMGZ-60°N
Abakhiqizi nobuchwepheshe bokukhiqiza
Abakhiqizi abakhulu bamafutha VGMZ
Njengamanje, kunamabhizinisi amathathu amakhulu akhiqiza uwoyela we-VMGZ ezweni lethu:
- IGazpromneft
- Rosneft
- I-Lukoil
Ingxenye eyinhloko amafutha ekhwalithi enhle athole ukuhlanzwa okukhethiwe futhi anokuqukethwe okuncane kwesibabule. Izingxenye ezinjalo zine-viscosity ephansi eguquguqukayo kanye nephuzu eliphezulu lokuthulula elibi. Zonke ezinye izakhiwo uhlobo lwe-VMGZ olunazo zitholakala ngokusebenzisa izithasiselo ezihlukahlukene ezihlinzeka nge-anti-wear, anti-foam, i-antioxidant kanye ne-corrosion properties.

IZICI EZINHLE
- Inikeza ukuvikelwa okuthembekile kwezingxenye zangaphakathi ngokumelene nokugqwala nokuguga kwemishini;
- Uhlu olubanzi lapho uketshezi lutholakala ngaphansi kwezimo zokusebenza, kusukela ku-35 ° С kuya ku-50 ° С;
- Ikhono lokuqala uhlelo ngaphandle kokulushisa;
- Asikho isidingo sokushintshwa kwe-hydraulic fluid yesizini;
- Izakhiwo zokulwa negwebu zisiza ukunciphisa ukungqubuzana koketshezi olusebenzayo;
Iseluleko sochwepheshe ngokukhetha nokusebenza
Ungasebenzisi i-VMGZ esetshenzisiwe noma uketshezi olusezingeni eliphansi, futhi ngisho nangaphezulu olungaziwa umsuka walo.
Imiphumela yokusebenza kwe-VMGZ esezingeni eliphansi:
- Izinga eliphezulu lokungcola, izingxenye zangaphakathi zezinhlelo ze-hydraulic.
- Ukuvala nokwehluleka kwesihlungi.
- Izinga eliphezulu lokuguga kanye nokugqwala kwezingxenye zangaphakathi.
- Ukwehluleka ngenxa yenhlanganisela yezinto ezingenhla.
Umbono wochwepheshe: Isikhathi sokuphumula kweminye imishini sibiza kakhulu, ngakho-ke hlala ubheka isimo soketshezi olusebenzisa amanzi bese ulushintsha ngesikhathi esifanele.
Lapho ukhetha, thatha njalo kubakhiqizi abathembekile. Izakhiwo eziyinhloko ze-VMGZ zicishe zifane kubo bonke abakhiqizi. Abakhiqizi bashintsha isethi yezithako ze-antioxidant kanye ne-anti-corrosion. Tadisha ngokucophelela ukwakheka bese ukhetha uwoyela ozokusiza ukwandise impilo yezinhlelo zakho ze-hydraulic. Kunoma yikuphi ungaqali ngentengo.
Izici ezimbili ezibalulekile okufanele uzicabangele lapho ukhetha:
- Iqoqo lezakhiwo ezihlinzekwa uwoyela we-VMGZ (ezikhonjiswe emibhalweni yezobuchwepheshe);
- Udumo negunya lomkhiqizo phakathi kwabasebenzisi bamasistimu asebenza ngogesi;
