Amafutha ezimboni I-40A

izinkomba zomzimba namakhemikhali

Izici eziyisisekelo zamafutha e-I-40A:

1. Ukuminyana ekamelweni lokushisa, kg/m³ - 810 ± 10.
2. I-kinematic viscosity, mm²/ s, ezingeni lokushisa elingu-50 ^°C - 35… 45.
3. I-kinematic viscosity, mm²/ s, ekushiseni kwe-100 ° C, hhayi ngaphansi kuka - 8,5.
4. iphoyinti elikhanyayo, ^°C, hhayi ngaphansi - 200.
5. Ukuqina kwezinga lokushisa, ^°C, hhayi ngaphansi kuka -15.
6. Inombolo ye-Acid, ngokuya nge-KOH - 0,05.
7. Inombolo ye-coke - 0,15.
8. Ubuningi bokuqukethwe komlotha,% - 0,005.

Uwoyela omusha wezimboni I-40A (kukhona negama elithi uwoyela IS-45 namafutha omshini C) kufanele anikezwe abathengi kuphela esimweni sokuqala sokuhlanzwa kwe-distillate futhi ngaphandle kwezithasiselo.

I-GOST 20799-88 iphinde inikeze ukuthi uma isetshenziswa njengoketshezi lwe-hydraulic, lolu hlobo lwamafutha kufanele luhlolwe ukuzinza kwalo ekucindezelweni okuhlukahlukene kokusebenza. Ukuzinza kwemishini kunqunywa ngokuvumelana nezinkomba zamandla okugunda wesendlalelo sokugcoba, esitholakala kugebe lobuchwepheshe phakathi kwezindawo zokungqubuzana eziseduze.

Isibonakaliso sesibili sokuzinza kwemishini yisikhathi sokubuyisela i-viscosity yamafutha, esethwe ngokwendlela ye-GOST 19295-94. Ngesicelo esengeziwe, uwoyela we-I-40A nawo uhlolwe ukuzinza kwe-colloidal. Ukuhlola kuhlanganisa ukunquma inani lamafutha elicindezelwe liphuma kugrisi langempela kusetshenziswa i-penetrometer elinganisiwe. Le nkomba iyadingeka ezimweni zokusebenza zamafutha emazingeni okushisa angaphandle ashintsha kakhulu.

I-analogue yamazwe ngamazwe yalokhu kuthambisa i-Mobil DTE Oil 26, ekhiqizwa ngokuvumelana ne-ISO 6743-81, kanye namafutha akhiqizwa ezinye izinkampani ezihlangabezana nezidingo zaleli zinga.

Isicelo

Uwoyela we-I-40A uthathwa njenge-medium-viscosity lubricant, esetshenziswa kangcono emishinini elayishwe kakhulu nezindlela lapho kukhula khona izingcindezi ezibalulekile zokuxhumana. Ukungabikho kwezithasiselo ezithile kwenza kube nokwenzeka ukusebenzisa la mafutha futhi njenge-diluent: kokubili okokugcoba okune-viscosity ephansi kakhulu (isibonelo, I-20A noma I-30A), kanye namafutha ane-viscosity eyengeziwe (isibonelo, I-50A ).

Ukuzinza kwe-oxidation okuhle kakhulu kusiza ukunciphisa isikhathi sokungasebenzi kanye nezindleko zokunakekela imishini ngokukhuthaza ukuhlanzeka kwesistimu nokunciphisa idiphozithi, ukwelula impilo yesihlungi sikawoyela namafutha.

Ukuvikelwa okuthuthukisiwe kokuvikela ukugqokwa nokugqwala kwezingxenye zesistimu kusetshenziswa izinhlobo ezahlukahlukene zokunakekelwa okujwayelekile kusiza ukunweba impilo yezingxenye zesistimu yobuchwepheshe futhi kwandise ukusebenza kwazo. Ngesikhathi sokukhiqiza, uwoyela we-I-40A uphathwa ngama-demulsifiers, ngakho-ke lesi sithambiso sivikela imishini kahle ekungeneni kwamanzi kuya ezindaweni zokuhlikihla.

Izindawo ezinengqondo zokusebenzisa uwoyela we-I-40A:

• Ama-Friction systems, lapho kuba khona ingozi yokuqoqwa kwamadiphozithi angaphezulu.
• Amasistimu we-hydraulic adinga umthamo wokuthwala okuphezulu nokuvikelwa kokugqoka.
• Imishini nezindlela ezihlala zisebenza endaweni egqwalile.
• Imishini yokusebenza ngensimbi esebenza ngengcindezi yenqubo ephakeme.

Uwoyela uzibonakalisa ngempumelelo njengengxenye yoketshezi olusebenzayo emshinini we-electroerosive wezinsimbi nama-alloys.

Intengo kawoyela wezimboni I-40A incike kumkhiqizi kanye nokupakishwa komkhiqizo:

• Lapho ukupakisha emiphongolweni enamandla 180 amalitha - kusuka ruble 12700.
• Lapho upakisha emathinini anamandla angama-5 amalitha - kusuka kuma-ruble angama-300.
• Lapho upakisha emathinini anamandla angama-10 amalitha - kusuka kuma-ruble angama-700.
