Ngokusho kwesigaba samazwe ngamazwe se-API, i-TSZp-8 ifakwe eqenjini le-GL-3, futhi ngokusho kwe-American SAE standard, inikezwa isigaba 75W-80. Lezi zimpawu zichaza:

  1. Iphesenti eliphelele lezithasiselo alikho ngaphezu kuka-2,7.
  2. Ukungenzeki kokusebenzisa amafutha kumagiya e-hypoid nasezinjinini.
  3. Isicelo esincanyelwayo sezindlela zokusebenza zezimoto ezinomthwalo omaphakathi wezinto ezigcotshiwe.
  4. Ukuba khona kwezithasiselo ezikhethekile ezinxephezela ukwanda kokungqubuzana kokuslayida.

Isici esihlukile samafutha okudlulisa we-TSZp-8 ukubola kwawo kwamanye ama-alloys angenayo insimbi (ithusi, ithusi), okubangelwa ukuba khona kwe-phosphorus esebenzayo kanye nezinhlanganisela zesulfure ekubunjweni kwayo. Ngakho-ke, kunconywa ukwengeza inani elithile le-corrosion inhibitors ekwakhiweni komkhiqizo, okungakhi i-emulsion enezingxenye eziyinhloko futhi kunganciphisi i-viscosity yamafutha kumanani angaphansi kuka-7,5 mm.2/ s.

Ukwenyuka kwe-viscosity kungesinye sezizathu zokuthi kungani uwoyela we-TSZp-8 unomthamo omkhulu womthwalo kunezinye izinhlobo ezidumile zamafutha egiya (isibonelo, i-TAP-15v).

Ezinye izici zomzimba nemishini kawoyela zimi kanje:

  • Ukuminyana, kg/m3: 850...900.
  • Ibanga le-viscosity liyi-100 °C, mm2/ s: 7,5… 8,5.
  • Izinga lokushisa lomlilo, ° С, hhayi ngaphansi: 164.
  • Ukuqina kwezinga lokushisa, °C, akusekho: -50.
  • Umthwalo wokusebenza olinganiselwe, N: - 2000.
  • Ubukhulu bomthwalo osebenzayo, N: 2800.

Kuwoyela wegiya okucatshangelwayo, ukukhiqizwa okunqunywa yizinkambiso ze-TU 38.1011280-89, iminonjana yesibabule ne-phosphorus compounds, kanye namanzi, kuvunyelwe.

Ukubuyekezwa okuningi kuphawula ukuthi ukuze kuqinisekiswe izinga eliphakeme lokuhlukahluka kwamafutha e-TSZp-8, kuyinto efiselekayo ukwengeza i-polymethacrylate noma i-polyalkylstyrene ekubunjweni kwayo. Ngenxa yalokho, uketshezi lwamafutha uma kushisa akukhuli kakhulu, kodwa amafutha aba yisimo sezulu sonke. Iphesenti lezithasiselo akufanele lidlule i-3 ... 5% yenani lomthamo we-lubricant. I-Polymethacrylate futhi iyiphuzu lokuthulula elicindezelayo, okwandisa ukusebenza kukawoyela emazingeni okushisa aphansi.

Ama-analogue angaphandle aseduze kawoyela we-TSZp-8 yi-Autran GM-MP evela kumkhiqizo we-British Petroleum, i-Deusol TFA yaseCastrol, kanye ne-Shell Donax TD.

Ukucacisa uphawu lwamafutha okudlulisela i-TSZp-8 kuhlanganisa:

  • T - ukudluliswa;
  • I-Szp - amafutha asetshenziswa ikakhulukazi kumagiya e-helical;
  • 8 - isilinganiso se-kinematic viscosity ku-100 °C, kwe mm2/ s.

Intengo yemikhiqizo inqunywa umthamo wokufakwa kwamafutha. Uma upakisha emiphongolweni enamandla angama-216 amalitha, amanani alo mkhiqizo aqala kusuka kuma-ruble angu-14000 20, futhi uma egcwele ama-canister angu-2500-litre - kusuka kuma-ruble angu-XNUMX.
