Txhim khu kev ntseeg tau pov thawj lub cav diesel - YaMZ 238M2, cov yam ntxwv thiab kev tsim qauv uas ua kom nws siv los ua lub zog rau ntau yam khoom siv.

YYaroslavl motors

Xyoo 1958, lub tsheb cog hauv Yaroslavl (YaAZ) tau hloov pauv mus rau hauv lub cev muaj zog (YaMZ), rau kev tsim khoom loj ntawm diesel xyaw. Thaum xub thawj, lub tuam txhab tsim YaAZ-206 thiab YaAZ-204 diesel xyaw (los ntawm 110 txog 225 hp), uas tau nruab nrog cov tsheb thauj khoom yav dhau los, xa mus rau kev tsim khoom ntxiv rau KrAZ tsheb cog hauv Kremenchug.

Nyob rau xyoo 1961, lub tuam txhab tau pib tsim lub zog ntawm nws tus kheej tsim YaMZ 236, 238 thiab 240. Cov cav tshiab muaj kev sib koom ua ke, thiab qhov sib txawv tseem ceeb yog tus naj npawb ntawm lub tog raj kheej. Xws li kev tsim qauv tsim ua kom muaj peev xwm ua kom lub zog diesel, feem ntau yog vim qhov nce ntawm cov thooj voos kheej kheej, los ntawm rau (YaMZ 236) mus rau kaum (YaMZ 240).

Lub peev xwm no tau muab lub zog hluav taws xob nrog ntau yam kev siv. Tsis tas li ntawd, cov txheej txheem ntau lawm tau yooj yim, uas ua rau muaj cov motors uas tau tsim. Nws tseem yog ib qho tseem ceeb uas kev sib koom ua ke dav tau pab txhawb kev ua haujlwm ntawm ntau yam khoom siv nrog lub cev muaj zog, nce kev ruaj ntseg.

YAMZ 238M2 engine

Kev tsim ua tiav ntawm YaMZ 238 diesel cav ua rau nws muaj peev xwm ua tiav ntau yam kev hloov kho tshiab txhawm rau txhawm rau txhim kho cov txheej txheem kev ua haujlwm thiab tsim ntau yam kev hloov kho kom ua tiav ntau yam kev xaiv rau tshuab thiab khoom siv. Tam sim no, cov nroj tsuag tseem tsim 22 kev hloov kho ntawm 238 lub cev muaj zog, suav nrog cov M2 Performance index.

Lub YaMZ 238M2 lub cav hloov cov qauv nrog "M" Performance index hauv cov kab ntau lawm thiab tau tsim tawm txij li xyoo 1988. Lub tshuab hluav taws xob diesel yog tus cwj pwm los ntawm cov yam ntxwv tseem ceeb hauv qab no:

• nrog cov khoom siv roj tshwj xeeb uas tso cai rau kev ua haujlwm ntawm lub tshuab hluav taws xob nyob rau hauv cov xwm txheej ntawm cov yob thiab muaj zog trim;
• roj mov system, ua nyob rau hauv ib qho kev sib cais nrog kev txhaj tshuaj ncaj qha;
• txo cov roj noj YaMZ 238M2;
• tsis muaj turbocharging;
• piston type booster pump.

Qhov nrov ntawm YaMZ 238M2 lub cav nrog cov neeg siv khoom tau lees paub los ntawm qhov tseeb tias cov nroj tsuag tam sim no tsim 15 diesel cav configurations ib zaug. Xws li tus lej loj yog ua tiav los ntawm kev siv cov khoom sib txawv ntawm cov tshuab hluav taws xob, cov khoom siv roj, pib.

Technical indicators

Cov yam ntxwv zoo ntawm YaMZ 238M2 xyuas kom muaj kev siv lub cav ntawmtxheej txheem sib txawv. Main lub cev muaj zog tsis:

• hom - diesel;
• duty cycle - plaub-stroke;
• version - V-shaped, nrog kev sib txawv ntawm 90 degrees;
• ntau tus thooj voos kheej kheej - 8;
• ua haujlwm ntim - 14.86 l;
• zog - 240,0 l. p.;
• tus lej siab tshaj plaws ntawm kev hloov pauv - 2350 rpm;
• compression ratio - 16.5;
• roj noj - 168 g / (hp-h);
• stroke - 14 cm;
• lub tog raj kheej txoj kab uas hla - 13;
• ntaus li qub - 16 daim;
• sib tov - direct txhaj;
• hnyav - 1.08 t;

• dimensions:

  • ntev - 1, 12 m,
  • dav – 1.01 m,
  • siab - 1.05 m,
  • resource ua ntej overhaul - 8000 teev;
  • cua txias - 20.0 l,
  • lubrication system - 29.0 l.
  • cua txias - 20.0 l,
  • lubrication system - 29.0 l.

• ntim ntim (tsis muaj radiators):

  • cua txias - 20.0 l,
  • lubrication system - 29.0 l.

Tsis tas li, ntawm cov yam ntxwv ntawm YaMZ 238M2, nws yog qhov tsim nyog yuav tsum nco ntsoov txo qis kev siv roj.

Txhawm rau kom ntseeg tau cov kev txwv tsis pub dhau, kev txhim kho lub cav ntawm cov txheej txheem kev pabcuam, kev saib xyuas yuav tsum tau ua raws sijhawm thiab ua haujlwm zoo, nrog rau lwm yam kev saib xyuas. Cov txheej txheem thiab zaus ntawm kev ua haujlwm no yog muab los ntawm cov chaw tsim khoom hauv phau ntawv tsim thiab pom zoo ua haujlwm rau YaMZ 238M2.

Diesel daim ntawv thov

Ntau qhov ua tiav ntawm chav tsev fais fab yog txuam nrog ntau yam kev siv. Nrog rau cov yam ntxwv zoo, YaMZ 238M2 yog siv rau ntawm cov tsheb hauv qab no thiab cov khoom siv hauv tsev:

• Tsheb:

  • MAZ (Belarus),
  • MoAZ (Belarus),
  • URAL ("Ural Automobile Plant").
• Nkoj lub cev muaj zog ("Bogorodsk Tshuab-Lub Tsev Cog").

• Cov khoom siv hluav taws xob:

  • khiav kho tshuab, tus kheej-propelled cranes (Kalugaputmash),
  • motor platforms ("Kirov Machine Plant"),
  • snowplows ("Sevdormash"),
  • railcars ("Muromteplovoz").
• Bulldozers ("ChSDM").
• Excavators (Lestekhkom).
• Diesel fais fab nroj tsuag ("Electric unit").
• Electrical units ("Tyumen-ship kit").

Tus tsim txhim khu kev qha ntawm YaMZ 238M2, cov yam ntxwv ntawm kev ua haujlwm, tus nqi qis thiab kev saib xyuas kom ua haujlwm tau zoo ntawm cov cuab yeej nruab nrog lub cav diesel.
