Tap-15 kapena Tad-17. Chochindikira ndi chiyani? Kusiyana

Tap-15 kapena Tad-17: kusiyana

Tap-15 kapena Tad-17? Ngati tilingalira za mankhwala a mafuta awa, ndiye kuti pali kusiyana kochepa. Onsewo ndi a mchere, chifukwa amapangidwa m'kati mwa distillation ndi distillation yamagulu ena amafuta. Tep-15 ndi yotsika mtengo, chifukwa chake kuchuluka kwa kupanikizika kwambiri ndi zowonjezera zowonjezera kumachepetsedwa pamenepo. Komanso, mamasukidwe akayendedwe Tep-15 ndi penapake m'munsi, ngakhale mbali zambiri zosuntha magalimoto (makamaka zoweta zoweta), chizindikiro ichi si wovuta.

Chitetezo chogwiritsa ntchito mafuta opangira giya omwe akuganiziridwa sichidziwika kokha ndi kukula kwa makulidwe awo pa kutentha kochepa (kwa Tad-17, kutentha kwa ntchito ndi -20 mpaka +135^ºC, ndi Tep-15 kuchokera -23 mpaka +130^ºC), komanso kuchuluka kwamphamvu kwamankhwala pokhudzana ndi kuyika zisindikizo zamabokosi. M'lingaliro ili, Tad-17 imagwira ntchito kwambiri. Lili ndi sulfure ndi phosphorous wambiri, zomwe zimapangitsa kuti pakhale machitidwe a mechanochemical pamtunda wa zida za hypoid. Chifukwa cha machitidwe otere, mafilimu amapangidwa kumeneko, omwe amawonjezera mphamvu yotsutsana ndi kulanda zinthuzo pansi pazifukwa zothamanga kwambiri za chinthu chimodzi chopatsirana choyandikana nacho. Pansi pazimenezi, si mitundu yonse ya zisindikizo za rabara zomwe zingakhale ndi kukana kokwanira kovala. Komanso, ngati synchronizer imapangidwa ndi mkuwa kapena aloyi yamkuwa, ndiye kuti kukana kwake kudzachepetsedwa.

M'malo mwake, Tep-15, amene alibe kuchuluka kwa reagents mankhwala yogwira, si tcheru kwambiri mlingo wa mafuta kukana mphira ndi kalasi ya aloyi zamkuwa.

Ndi chiyani chokhuthala - Tap-15 kapena Tad-17?

Poyerekeza, ndikofunikira kuwunika osati mtengo wonse wa viscosity, komanso kusintha kwake pakuwonjezera kutentha.

Mafuta amtundu wa Tep-15 malinga ndi GOST 17479.2-85 ndi mafuta amafuta a gulu lachiwiri, ali ndi zowonjezera zowonjezera, choncho amapangidwa kuti azigwiritsidwa ntchito mogwira mtima pansi pa katundu wakunja mpaka 2 GPa ndi kutentha kwakukulu mpaka 2.^ºC. Panthawi imodzimodziyo, Tad-17 imaphatikizapo zowonjezera zowonjezera, ndipo ndi za gulu la 5, zomwe katundu wakunja pazitsulo ndi magiya amatha kufika 3 GPa kapena kuposa, pa kutentha kwakukulu mpaka 150.^ºC.

Choncho, mayunitsi mulingo woyenera kwambiri ntchito Tep-15 ndi cylindrical, bevel ndi - pang'ono - nyongolotsi magiya, amene ntchito pa liwiro ndi otsika kutsetsereka, ndi kwa Tad-17 - makamaka hypoid magiya, kumene liwiro kufika 5 ... 7 % ya giya yozungulira yothamanga. Chifukwa chake, chizindikiro cha kuvala mumikhalidwe yotere chimawonjezeka kuchokera ku 0,4 mpaka 0,5.

Kuwunika kwa kukhazikika kwa zizindikiro za viscosity kutengera kutentha kwa voliyumu ya node kumapereka mfundo zotsatirazi. Kwa Tep-15, kukhuthala kumasintha motere:

• Pa 100^ºC - 15… 16 mm²/ s
• Pa 50^ºC - 100… 120 mm²/ s
• Pa 20^ºC - 870… 1150 mm²/ s

Chifukwa chake, zizindikiro zofanana za Tad-17 ndi:

• Pa 100^ºC - 18… 20 mm²/ s
• Pa 50^ºC - 180… 220 mm²/ s
• Pa 20^ºC - 1500… 1600 mm²/ s

Zomwezo, Tap-15 kapena Tad-17? Poyerekeza momwe mafuta opangira mafuta amagwirira ntchito, timawona kuti mphamvu yamafuta a giya ya Tad-17 ndiyokwera kwambiri, chifukwa chake, imatha kugwiritsidwa ntchito pakuchulukitsitsa pamakina, pomwe kukhalapo kwa nthawi yayitali kwa filimu yamafuta pamtunda wolekanitsa magawo opaka. mokakamizidwa. Pa nthawi yomweyo, "Tep-15" ndi zothandiza kwambiri ntchito gearbox thalakitala, komanso magalimoto sing'anga-ntchito.
