VMGZ decoding - oli ea haeteroliki
Tse ka hare
Nako le nako, oli ea VMGZ e sebelisoa e le mokelikeli o sebetsang mechineng ea hydraulic. Tlhaloso ea lebitso lena: multigrade oli ea hydraulic e teteaneng.
Ts'ebeliso ea oli ea VMGZ
Oli ea VMGZ e sebelisoa lits'ebetsong tsa taolo ea hydraulic, hammoho le li-drive tsa hydraulic mefuteng e latelang ea lisebelisoa:
- Lisebelisoa tse khethehileng tsa tsela
- Lisebelisoa tsa ho phahamisa le ho tsamaisa
- Mechini ea kaho
- Lisebelisoa tsa meru
- Likoloi tse fapaneng tse batloang
Ts'ebeliso ea VMGZ e netefatsa ts'epahalo ea ts'ebetso ea sesebelisoa sa tekheniki, le ho qala ha hydraulic drive maemong a tlase haholo a moea.
Tlatsetso ea bohlokoahali ea oli ena ke hore ha e hloke ho fetoloa ha e sebetsa ka linako tse fapaneng tsa selemo. Oli e loketse ts'ebetso ea mocheso ho tloha ho -35 ° C ho isa ho 50 ° C, ho latela mofuta oa pompo e sebelisoang tsamaisong ena.
Litšobotsi tsa setsebi sa oli ea VMGZ
Ha ho etsoa oli ena, lisebelisoa tsa liminerale tse nang le viscosity e tlase tse nang le viscosity e fokolang e tlase li sebelisoa. Likarolo tsena li fumanoa ka likaroloana tsa peteroleamo ho sebelisoa hydrocracking kapa waxing e tebileng. Ka thuso ea li-additives le li-additives tse fapaneng, oli e tlisoa ho tsitsiso e lakatsehang. Mefuta ea litlatsetso e ekelitsoeng ho oli ea VMGZ: antifoam, antiwear, antioxidant.
Oli ea haeteroliki e bonts'a thepa ea setlolo se setle haholo, e sa phophothe feela, thepa ena ea bohlokoa e thusa ho qoba tahlehelo ea oli nakong ea ts'ebetso. Hape, sehlahisoa sena se hanela ho thehoa ha pula, e nang le phello e ntle ho botsitso ba mechini. Lihlahisoa tsena li na le litšobotsi tse phahameng tsa ho thibela ts'enyeho mme li ipakile e le mokhoa o motle oa ho sireletsa tšepe. E 'ngoe ea mekhahlelo ea bohlokoahali ke bokhoni ba ho qala lits'ebetso ntle le ho futhumatsa oli.
Litšobotsi tsa ts'ebetso ea oli ea VMGZ:
- E tiileng e qamathelang e seng ka tlase ho 10 m / s ka 50 ° С.
- E tiileng e qamathelang e seng ho feta 1500 ka 40 ° С.
- Lenane la Viscosity 160
- Flash e ka tlase ho 135 ° С
- thatafatsa t -60 ° С
- Litšila tsa mechini ha lia lumelloa
- Ha ho metsi a lumelloang
- Oli e tlameha ho hanela ts'enyeho ea tšepe
- Boikarabello ha bo fetang 865 kg / m3 ka 20 ° C
- Palo ea seretse ha e fete 0,05% ea boima bohle
Bahlahisi ba oli VMGZ
Bahlahisi ba ka pele ba oli e joalo ke likhamphani tse kholo tsa 4: Lukoil, Gazpromneft, Sintoil, TNK.
Boholo ba bareki ba oli ena ba fana ka khetho ea bona molemong oa lik'hamphani tsa Lukoil le Gazprom. Ho na le maikutlo a matla har'a basebetsi le bakhanni ba lisebelisoa tse ikhethang tsa hore lioli tsa hydraulic tsa lik'hamphani tsena li hlahisoa ka thepa e ts'oanang ho tsoa likarolong tse tšoanang tsa oli.
U ka boela oa utloa likarabo tse fosahetseng mabapi le litheko tsa lioli tsa haeteroliki tse tsoang kantle, ka mohlala, oli e bonolo ka ho fetisisa ea Mobil e tla bitsa makhetlo a 2-3 ho feta VMGZ ho tsoa ho baetsi ba malapeng.
Mamello ke karolo ea bohlokoa ho khethoeng ha oli ea haeteroliki, hape le ho khethoeng ha oli ea enjine bakeng sa koloi.
Ha u khetha oli ea haeteroliki, ho bohlokoa ho khetha sehlahisoa sa boleng, ho seng joalo, hammoho le oli ea VMGZ ea boleng bo tlase, ho boetse ho na le mathata a mangata:
- Ho silafala ho eketsehileng ha li-hydraulic
- Metlhotlo e koetsoeng
- Ho senyeha ho potlakileng le ts'enyeho ea likarolo
Ka lebaka leo, nako ea phomolo e hlaha mosebetsing oa ho lokisa kapa oa tlhahiso, o kenyelletsang litšenyehelo tse phahameng haholo ho feta phapang ea theko lipakeng tsa oli ea boleng bo holimo le leshano le theko e tlaase.
Bothata bo boholo ba ho khetha moetsi oa VMGZ ke mofuta o batlang o ts'oana oa oli ho tsoa ho baetsi ba fapaneng. Sena se bakoa ke sete ea li-additives tse nyane tse sebelisoang ke lik'hamphani tsohle. Ka nako e ts'oanang, ho leka ho hapa tlholisanong, e 'ngoe le e' ngoe ea lik'hamphani tse etsang thepa e tla shebana le thepa e 'ngoe ea oli, leha e sa fapane le mohatelli.
fihlela qeto e
Oli ea VMGZ ke molekane ea ke keng a khutlisoa oa mekhoa ea haeteroliki. Leha ho le joalo, o hloka ho atamela ka hloko khetho ea oli mme o nahane ka lintlha tse latelang:
- Ha u khetha, ho bohlokoa ho ithuta ka hloko sebopeho sa haeteroliki ho tseba hore na ho fanoa ka mamello ea oli mochining ona.
- Ho bohlokoa ho hlahloba oli hore na e latela melao ea ISO le SAE
- Ha u khetha oli ea VMGZ, theko e ke ke ea nkuoa e le mokhoa o ka sehloohong, sena se ka fetoha chelete e belaetsang

Lipotso le likarabo:
Oli ea Vmgz e hlalosoa joang? Ke oli e teteaneng ea multigrade hydraulic. Oli ena ha e thehe sediments, e lumellang ho sebelisoa ha mekhoa sebakeng se bulehileng.
Oli ea Vmgz e sebelisetsoa eng? Oli ena ea li-hydraulic hydraulic e sebelisoa lisebelisoa tse lulang li sebetsa sebakeng se bulehileng: kaho, ho rema lifate, ho phahamisa le ho tsamaisa, joalo-joalo.
Viscosity ea Vmgz ke eng? Ka mocheso oa likhato + 40, viscosity ea oli e tsoa ho 13.5 ho ea ho 16.5 sq.mm / s. Ka lebaka lena, e boloka thepa ea eona khatellong ea ho fihla ho 25 MPa.
